performance tests .SH SYNOPSIS \fBpgreplay\fP [\fIparse options\fR] [\fIreplay options\fR] [\fB-d\fR \fIlevel\fR] [\fIinfile\fR] .br \fBpgreplay\fP \fB-f\fP [\fIparse options\fR] [\fB-o\fP \fIoutfile\fR] [\fB-d\fR \fIlevel\fR] [\fIinfile\fR] .br \fBpgreplay\fP \fB-r\fP [\fIreplay options\fR] [\fB-d\fR \fIlevel\fR] [\fIinfile\fR] .SH DESCRIPTION \fBpgreplay\fR reads a PostgreSQL log file (\fInot\fR a WAL file), extracts the SQL statements and executes them in the same order and relative time against a PostgreSQL database cluster. A final report gives you a useful statistical analysis of your workload and its execution. .P In the first form, the log file \fIinfile\fR is replayed at the time it is read. .P With the \fB-f\fR option, \fBpgreplay\fR will not execute the statements, but write them to a \(oqreplay file\(cq \fIoutfile\fR that can be replayed with the third form. .P With the \fB-r\fP option, \fBpgreplay\fR will execute the statements in the replay file \fIinfile\fR that was created by the second form. .P If the execution of statements gets behind schedule, warning messages are issued that indicate that the server cannot handle the load in a timely fashion. The idea is to replay a real-world database workload as exactly as possible. .P To create a log file that can be parsed by \fBpgreplay\fR, you need to set the following parameters in \fBpostgresql.conf\fR: .IP \fBlog_min_messages=error\fR (or more) .br \fBlog_min_error_statement=log\fR (or more) .br \fBlog_connections=on\fR .br \fBlog_disconnections=on\fR .br \fBlog_line_prefix=\(aq%m|%u|%d|%c|\(aq\fR (if you don\(aqt use CSV logging) .br \fBlog_statement=\(aqall\(aq\fR .br \fBlc_messages\fR must be set to English (encoding does not matter) .br \fBbytea_output=escape\fR (from version 9.0 on, only if you want to replay the log on 8.4 or earlier) .P The database cluster against which you replay the SQL statements must be a clone of the database cluster that generated the logs from the time \fIimmediately before\fR the logs were generated. .P \fBpgreplay\fR is useful for performance tests, particularly in the following situations: .TP 4 * You want to compare the performance of your PostgreSQL application on different hardware or different operating systems. .TP 4 * You want to upgrade your database and want to make sure that the new database version does not suffer from performance regressions that affect you. .P Moreover, \fBpgreplay\fR can give you some feeling as to how your application \fImight\fR scale by allowing you to try to replay the workload at a higher speed. Be warned, though, that 500 users working at double speed is not really the same as 1000 users working at normal speed. .SH OPTIONS .SS Parse options: .TP \fB-c\fR Specifies that the log file is in \(aqcsvlog\(aq format (highly recommended) and not in \(aqstderr\(aq format. .TP \fB-b\fR \fItimestamp\fR Only log entries greater or equal to that timestamp will be parsed. The format is \fBYYYY-MM-DD HH:MM:SS.FFF\fR like in the log file. An optional time zone part will be ignored. .TP \fB-e\fR \fItimestamp\fR Only log entries less or equal to that timestamp will be parsed. The format is \fBYYYY-MM-DD HH:MM:SS.FFF\fR like in the log file. An optional time zone part will be ignored. .TP \fB-q\fR Specifies that a backslash in a simple string literal will escape the following single quote. This depends on configuration options like \fBstandard_conforming_strings\fR and is the default for server version 9.0 and less. .SS Replay options: .TP \fB-h\fR \fIhostname\fR Host name where the target database cluster is running (or directory where the UNIX socket can be found). Defaults to local connections. .br This works just like the \fB-h\fR option of \fBpsql\fR. .TP \fB-p\fR \fIport\fR TCP port where the target database cluster can be reached. .TP \fB-W\fR \fIpassword\fR By default, \fBpgreplay\fR assumes that the target database cluster is configured for \fItrust\fR authentication. With the \fB-W\fR option you can specify a password that will be used for all users in the cluster. .TP \fB-s\fR \fIfactor\fR Speed factor for replay, by default 1. This can be any valid positive floating point number. A \fIfactor\fR less than 1 will replay the workload in \(oqslow motion\(cq, while a \fIfactor\fR greater than 1 means \(oqfast forward\(cq. .TP \fB-E\fR \fIencoding\fR Specifies the encoding of the log file, which will be used as client encoding during replay. If it is omitted, your default client encoding will be used. .TP \fB-j\fR If all connections are idle, jump ahead to the next request instead of sleeping. This will speed up replay. Execution delays will still be reported correctly, but replay statistics will not contain the idle time. .SS Output options: .TP \fB-o\fP \fIoutfile\fR specifies the replay file where the statements will be written for later replay. .SS Debug options: .TP \fB-d\fR \fIlevel\fR Specifies the trace level (between 1 and 3). Increasing levels will produce more detailed information about what \fBpgreplay\fR is doing. .TP \fB-v\fR Prints the program version and exits. .SH ENVIRONMENT .TP \fBPGHOST\fR Specifies the default value for the \fB-h\fR option. .TP \fBPGPORT\fR Specifies the default value for the \fB-p\fR option. .TP \fBPGCLIENTENCODING\fR Specifies the default value for the \fB-E\fR option. .SH LIMITATIONS \fBpgreplay\fR can only replay what is logged by PostgreSQL. This leads to some limitations: .TP 4 * \fBCOPY\fR statements will not be replayed, because the copy data are not logged. .TP 4 * Fast-path API function calls are not logged and will not be replayed. Unfortunately, this includes the Large Object API. .TP 4 * Since the log file is always in the server encoding (which you can specify with the \fB-E\fR switch of \fBpgreplay\fR), all \fBSET client_encoding\fR statements will be ignored. .TP 4 * Since the preparation time of prepared statements is not logged (unless \fBlog_min_messages\fR is \fBdebug2\fR or more), these statements will be prepared immediately before they are first executed during replay. .TP 4 * Because the log file contains only text, query parameters and return values will always be in text and never in binary format. If you use binary mode to, say, transfer large binary data, \fBpgreplay\fR can cause significantly more network traffic than the original run. .TP 4 * Sometimes, if a connection takes longer to complete, the session ID unexpectedly changes in the PostgreSQL log file. This causes \fBpgreplay\fR to treat the session as two different ones, resulting in an additional connection.

This can speed up replay. The statistics will not include the skipped time, but delay warnings will work as expected. Idea and original patch by John Lumby. Bugfixes: - Fix failure to parse string constants like E'\\' where the backslash before a quotation mark is backslash-quoted. Bug discovered by Jeff Frost. Version 1.1.0 Feb 09 2012 Enhancements: - Respect environment variable DESTDIR in Makefile for RPM packagers. - Improve execution delay reporting by introducing more intelligent time steps when a report is written; every 10 seconds is way too spammy. - Add documentation for interaction with pgFouine to the README. Bugfixes: - Fix incorrect assumption that everything that starts with a dollar sign is a dollar quoted string. This used to trigger bogus "end of dollar quote not found" error messages when $n placeholders are used in PREPARE statements. Discovered and fixed by Todd Owen. - When pgreplay waited for a response on a connection because it needed to send the next command, it used to sleep for one millisecond before polling the socket again. This proved to be too long on busy systems, where replay started to lag behind. Now pgreplay will not sleep, but keep polling until the response is there. Version 1.0.0 Jun 03 2011 Bugfixes: - Fix a connection and memory leak introduced by the new handling of FATAL connection errors in 0.9.1. Discovered by Denis Kostin. Version 0.9.1 Feb 26 2011 Enhancements: - Calculate parse and execution statistics and display them at the end of the run. Bugfixes: - Use "=" instead of "==" in "test" comparisons in configure. This improves portability. - Change replay file timestamp to seconds after midnight of 2000-01-01 in local time. This makes the replay file format independent of time zones and avoids problems with mktime(3) implementations that don't like the UNIX epoch. - Ignore string literals in filter_bad_statements during log file parsing. This keeps the function from getting confused by the contents of the string. Discovered by Josh Berkus. - Correctly handle prepared statements without parameters. Discovered by Grigorij Lipin. - Fix a corner case bug in read_log_line that can cause data corruption when parsing a stderr log. Discovered by Grigorij Lipin. - Skip memory dumps in stderr log caused by "out of memory" errors instead of gagging on them. Discovered by Grigorij Lipin. - Don't gag if a connection attempt results in a FATAL error during replay.

If the execution of statements gets behind schedule, warning messages are issued that indicate that the server cannot handle the load in a timely fashion. A final report gives you a useful statistical analysis of your workload and its execution. The idea is to replay a real-world database workload as exactly as possible. This is useful for performance tests, particularly in the following situations: - You want to compare the performance of your PostgreSQL application on different hardware or different operating systems. - You want to upgrade your database and want to make sure that the new database version does not suffer from performance regressions that affect you. Moreover, pgreplay can give you some feeling as to how your application *might* scale by allowing you to try to replay the workload at a higher speed (if that is possible, see "implementation details" below). Be warned, though, that 500 users working at double speed is not really the same as 1000 users working at normal speed. While pgreplay will find out if your database application will encounter performance problems, it does not provide a lot of help in the analysis of the cause of these problems. Combine pgreplay with a specialized analysis program like pgFouine (http://pgfouine.projects.postgresql.org/) for that. As an additional feature, pgreplay lets you split the replay in two parts: you can parse the log file and create a "replay file", which contains just the statements to be replayed and is hopefully much smaller than the original log file. Such a replay file can then be run against a database. pgreplay is written by Laurenz Albe and is inspired by "Playr" which never made it out of Beta. Installation ============ pgreplay needs PostgreSQL 8.0 or better. It is supposed to compile without warnings and run on all platforms supported by PostgreSQL. Since I only got to test it on Linux, AIX, FreeBSD and Windows, there may be problems with other platforms. I am interested in reports and fixes for these platforms. On Windows, only the MinGW build environment is supported (I have no other compiler). That means that there is currently no 64-bit build for Windows (but a 32-bit executable should work fine anywhere). To build pgreplay, you will need the pg_config utility. If you installed PostgreSQL using installation packages, you will probably have to install the development package that contains pg_config and the header files. If PostgreSQL is installed in the default location, the installation process will look like this: unpack the tarball ./configure make make test (optional, described below) make install (as superuser) If your PostgreSQL installation is in a nonstandard directory, you will have to use the --with-postgres= switch of "configure". Unless you link it statically, pgreplay requires the PostgreSQL client shared library on the system where it is run. The following utilities are only necessary if you intend to develop pgreplay: - autoconf 2.62 or better to generate 'configure' - GNU tar to 'make tarball' (unless you want to roll it by hand) - groff to make the HTML documentation with 'make html' Testing ------- You can run a test on pgreplay before installing by running "make test". This will parse sample log files and check that the result is as expected. Then an attempt is made to replay the log files and check if that works as expected. For this you need psql installed and a PostgreSQL server running (on this or another machine) so that the following command will succeed: psql -U postgres -d postgres -l You can setup the PGPORT and PGHOST environment variables and a password file for the user if necessary. Usage ===== First, you will need to record your real-life workload. For that, set the following parameters in postgresql.conf: log_min_messages = error (or more) (if you know that you have no cancel requests, 'log' will do) log_min_error_statement = log (or more) log_connections = on log_disconnections = on log_line_prefix = '%m|%u|%d|%c|' (if you don't use CSV logging) log_statement = 'all' lc_messages must be set to English (the encoding does not matter) bytea_output = escape (from version 9.0 on, only if you want to replay the log on 8.4 or earlier) It is highly recommended that you use CSV logging, because anything that the PostgreSQL server or any loaded modules write to standard error will be written to the stderr log and might confuse the parser. Then let your users have their way with the database. Make sure that you have a pg_dumpall of the database cluster from the time of the start of your log file (or use the -b option with the time of your backup). Alternatively, you can use point in time recovery to clone your database at the appropriate time. When you are done, restore the database (in the "before" state) to the machine where you want to perform the load test and run pgreplay against that database. Try to create a scenario as similar to your production system as possible (except for the change you want to test, of course). For example, if your clients connect over the network, run pgreplay on a different machine from where the database server is running. Since passwords are not logged (and pgreplay consequently has no way of knowing them), you have two options: either change pg_hba.conf on the test database to allow "trust" authentication or (if that is unacceptable) create a password file as described by the PostgreSQL documentation. Alternatively, you can change the passwords of all application users to one single password that you supply to pgreplay with the -W option. Limitations =========== pgreplay can only replay what is logged by PostgreSQL. This leads to some limitations: - COPY statements will not be replayed, because the copy data are not logged. I could have supported COPY TO statements, but that would have imposed a requirement that the directory structure on the replay system must be identical to the original machine. And if your application runs on the same machine as your database and they interact on the file system, pgreplay will probably not help you much anyway. - Fast-path API function calls are not logged and will not be replayed. Unfortunately, this includes the Large Object API. - Since the log file is always written in the database encoding (which you can specify with the -E switch of pgreplay), all "SET client_encoding" statements will be ignored. - If your cluster contains databases with different encoding, the log file will have mixed encoding as well. You cannot use pgreplay well in such an environment, because many statements against databases whose encoding does not match the -E switch will fail. - Since the preparation time of prepared statements is not logged (unless log_min_messages is debug2 or more), these statements will be prepared immediately before they are first executed during replay. While pgreplay makes sure that commands are sent to the server in the order in which they were originally executed, there is no way to guarantee that they will be executed in the same order during replay: Network delay, processor contention and other factors may cause a later command to "overtake" an earlier one. While this does not matter if the commands don't affect each other, it can lead to SQL statements hitting locks unexpectedly, causing replay to deadlock and "hang". This is particularly likely if many different sessions change the same data repeatedly in short intervals. You can work around this problem by canceling the waiting statement with pg_cancel_backend. Replay should continue normally after that. Implementation details ====================== pgreplay will track the "session ID" associated with each log entry (the session ID uniquely identifies a database connection). For each new session ID, a new database connection will be opened during replay. Each statement will be sent on the corresponding connection, so transactions are preserved and concurrent sessions cannot get in each other's way. The order of statements in the log file is strictly preserved, so there cannot be any race conditions caused by different execution speeds on separate connections. On the other hand, that means that long running queries on one connection may stall execution on concurrent connections, but that's all you can get if you want to reproduce the exact same workload on a system that behaves differently. As an example, consider this (simplified) log file: session 1|connect session 2|connect session 1|statement: BEGIN session 1|statement: SELECT something(1) session 2|statement: BEGIN session 2|statement: SELECT something(2) session 1|statement: SELECT something(3) session 2|statement: ROLLBACK session 2|disconnect session 1|statement: COMMIT session 2|disconnect This will cause two database connections to be opened, so the ROLLBACK in session 2 will not affect session 1. If "SELECT something(2)" takes longer than expected (longer than it did in the original), that will not stall the execution of "SELECT something(3)" because it runs on a different connection. The ROLLBACK, however, has to wait for the completion of the long statement. Since the order of statements is preserved, the COMMIT on session 1 will have to wait until the ROLLBACK on session 2 has started (but it does not have to wait for the completion of the ROLLBACK). pgreplay is implemented in C and makes heavy use of asynchronous command processing (which is the reason why it is implemented in C). This way a single process can handle many concurrent connections, which makes it possible to get away without multithreading or multiprocessing. This avoids the need for synchronization and many portability problems. But since TINSTAAFL, the choice of C brings along its own portability problems. Go figure. Replay file format ------------------ The replay file is a binary file, integer numbers are stored in network byte order. Each record in the replay file corresponds to one database operation and is constructed as follows: - 4-byte unsigned int: log file timestamp in seconds since 2000-01-01 - 4-byte unsigned int: fractional part of log file timestamp in microseconds - 8-byte unsigned int: session id - 1-byte unsigned int: type of the database action: 0 is connect 1 is disconnect 2 is simple statement execution 3 is statement preparation 4 is execution of a prepared statement 5 is cancel request - The remainder of the record is specific to the action, strings are stored with a preceeding 4-byte unsigned int that contains the length. Read the source for details. - Each record is terminated by a new-line character (byte 0x0A). pgreplay and pgFouine ===================== pgFouine (http://pgfouine.projects.postgresql.org/) is a PostgreSQL log file analyzer that allows you to understand your database workload and find bottlenecks and slow queries. Because both pgreplay and pgFouine target performance questions, it would be nice if they could operate on the same log files. But pgFouine needs the statement to be logged along with its duration, which is logged at the end of query execution, whereas pgreplay needs it at execution start time, so they cannot use the same log file. If you use CSV logging, there is a workaround with which you can turn a log file for pgFouine into a log file for pgreplay. The following describes this procedure for PostgreSQL 8.4 (there is an additional field in the CSV log from 9.0 on, and pgFouine currently does not work with the new format). For recording, use the following configuration parameters: log_destination = 'csvlog' redirect_stderr = on log_min_messages = error log_min_error_statement = log log_connections = on log_disconnections = on log_duration = off log_min_duration_statement = 0 log_statement = 'none' lc_messages must be set to English (the encoding does not matter) The resulting CSV log file can be parsed by pgFouine. Then you need a PostgreSQL database to create a new CSV file as follows: CREATE TABLE postgres_log ( log_time timestamp(3) with time zone, user_name text, database_name text, process_id integer, connection_from text, session_id text, session_line_num bigint, command_tag text, session_start_time timestamp with time zone, virtual_transaction_id text, transaction_id bigint, error_severity text, sql_state_code text, message text, detail text, hint text, internal_query text, internal_query_pos integer, context text, query text, query_pos integer, location text ); COPY postgres_log FROM '/path/to/for_pgfouine.csv' WITH CSV; UPDATE postgres_log SET log_time = log_time - CAST(substring(message FROM E'\\d+.\\d* ms') AS interval), message = regexp_replace(message, E'^duration: \\d+.\\d* ms ', '') WHERE error_severity = 'LOG' AND message ~ E'^duration: \\d+.\\d* ms '; COPY (SELECT to_char(log_time, 'YYYY-MM-DD HH24:MI:SS.MS TZ'), user_name, database_name, process_id, connection_from, session_id, session_line_num, command_tag, session_start_time, virtual_transaction_id, transaction_id, error_severity, sql_state_code, message, detail, hint, internal_query, internal_query_pos, context, query, query_pos, location FROM postgres_log ORDER BY log_time, session_line_num) TO '/path/to/for_pgreplay.csv' WITH CSV; The resulting "for_pgreplay.csv" can be parsed by pgreplay.

NAME

pgreplay − PostgreSQL log file replayer for performance tests

SYNOPSIS

pgreplay [parse options] [replay options] [-d level] [infile]
pgreplay -f [parse options] [-o outfile] [-d level] [infile]
pgreplay -r [replay options] [-d level] [infile]

DESCRIPTION

pgreplay reads a PostgreSQL log file (not a WAL file), extracts the SQL statements and executes them in the same order and relative time against a PostgreSQL database cluster. A final report gives you a useful statistical analysis of your workload and its execution.

In the first form, the log file infile is replayed at the time it is read.

With the -f option, pgreplay will not execute the statements, but write them to a ‘replay file’ outfile that can be replayed with the third form.

With the -r option, pgreplay will execute the statements in the replay file infile that was created by the second form.

If the execution of statements gets behind schedule, warning messages are issued that indicate that the server cannot handle the load in a timely fashion. The idea is to replay a real-world database workload as exactly as possible.

To create a log file that can be parsed by pgreplay, you need to set the following parameters in postgresql.conf:

log_min_messages=error (or more)
log_min_error_statement=log (or more)
log_connections=on
log_disconnections=on
log_line_prefix='%m|%u|%d|%c|' (if you don't use CSV logging)
log_statement='all'
lc_messages must be set to English (encoding does not matter)
bytea_output=escape (from version 9.0 on, only if you want to replay the log on 8.4 or earlier)

The database cluster against which you replay the SQL statements must be a clone of the database cluster that generated the logs from the time immediately before the logs were generated.

pgreplay is useful for performance tests, particularly in the following situations:

*

You want to compare the performance of your PostgreSQL application on different hardware or different operating systems.

*

You want to upgrade your database and want to make sure that the new database version does not suffer from performance regressions that affect you.

Moreover, pgreplay can give you some feeling as to how your application might scale by allowing you to try to replay the workload at a higher speed. Be warned, though, that 500 users working at double speed is not really the same as 1000 users working at normal speed.

OPTIONS

Parse options:

-c

Specifies that the log file is in 'csvlog' format (highly recommended) and not in 'stderr' format.

-b timestamp

Only log entries greater or equal to that timestamp will be parsed. The format is YYYY-MM-DD HH:MM:SS.FFF like in the log file. An optional time zone part will be ignored.

-e timestamp

Only log entries less or equal to that timestamp will be parsed. The format is YYYY-MM-DD HH:MM:SS.FFF like in the log file. An optional time zone part will be ignored.

-q

Specifies that a backslash in a simple string literal will escape the following single quote. This depends on configuration options like standard_conforming_strings and is the default for server version 9.0 and less.

Replay options:
-h hostname

Host name where the target database cluster is running (or directory where the UNIX socket can be found). Defaults to local connections.
This works just like the -h option of psql.

-p port

TCP port where the target database cluster can be reached.

-W password

By default, pgreplay assumes that the target database cluster is configured for trust authentication. With the -W option you can specify a password that will be used for all users in the cluster.

-s factor

Speed factor for replay, by default 1. This can be any valid positive floating point number. A factor less than 1 will replay the workload in ‘slow motion’, while a factor greater than 1 means ‘fast forward’.

-E encoding

Specifies the encoding of the log file, which will be used as client encoding during replay. If it is omitted, your default client encoding will be used.

-j

If all connections are idle, jump ahead to the next request instead of sleeping. This will speed up replay. Execution delays will still be reported correctly, but replay statistics will not contain the idle time.

Output options:
-o outfile

specifies the replay file where the statements will be written for later replay.

Debug options:
-d level

Specifies the trace level (between 1 and 3). Increasing levels will produce more detailed information about what pgreplay is doing.

-v

Prints the program version and exits.

ENVIRONMENT

PGHOST

Specifies the default value for the -h option.

PGPORT

Specifies the default value for the -p option.

PGCLIENTENCODING

Specifies the default value for the -E option.

LIMITATIONS

pgreplay can only replay what is logged by PostgreSQL. This leads to some limitations:

*

COPY statements will not be replayed, because the copy data are not logged.

*

Fast-path API function calls are not logged and will not be replayed. Unfortunately, this includes the Large Object API.

*

Since the log file is always in the server encoding (which you can specify with the -E switch of pgreplay), all SET client_encoding statements will be ignored.

*

Since the preparation time of prepared statements is not logged (unless log_min_messages is debug2 or more), these statements will be prepared immediately before they are first executed during replay.

*

Because the log file contains only text, query parameters and return values will always be in text and never in binary format. If you use binary mode to, say, transfer large binary data, pgreplay can cause significantly more network traffic than the original run.

*

Sometimes, if a connection takes longer to complete, the session ID unexpectedly changes in the PostgreSQL log file. This causes pgreplay to treat the session as two different ones, resulting in an additional connection. This is arguably a bug in PostgreSQL.
