Addresses on which to expose metrics and web interface. Repeatable for multiple addresses. --web.config.file="" [EXPERIMENTAL] Path to configuration file that can enable TLS or authentication. --buckets="5e-05,0.0001,0.0002,0.0004,0.0008,0.0016,0.0032,0.0064,0.0128,0.0256,0.0512,0.1024,0.2048,0.4096,0.8192,1.6384,3.2768,6.5536,13.1072,26.2144" A comma delimited list of buckets to use -i, --ping.interval=1s Ping interval duration --privileged Run in privileged ICMP mode -s, --ping.size=56 Ping packet size in bytes --log.level=info Only log messages with the given severity or above. One of: [debug, info, warn, error] --log.format=logfmt Output format of log messages. One of: [logfmt, json] --version Show application version. Args: [] List of hosts to ping ``` ## Configuration The prober can take a list of targets and parameters from the command line or from a yaml config file. Example config: ```yaml --- targets: - hosts: - host1 - host2 interval: 1s # Duration, Default 1s. network: ip # One of ip, ip4, ip6. Default: ip (automatic IPv4/IPv6) protocol: icmp # One of icmp, udp. Default: icmp (Requires privileged operation) size: 56 # Packet data size in bytes. Default 56 (Range: 24 - 65535) source: 127.0.1.1 # Souce IP address to use. Default: None (automatic selection) ``` In each host group the `interval`, `network`, and `protocol` are optional. The interval Duration is in [Go time.ParseDuration()](https://golang.org/pkg/time/#ParseDuration) syntax. The config is read on startup, and can be reloaded with the SIGHUP signal, or with an HTTP POST to the URI path `/-/reload`. ## Building and running Requires Go >= 1.22 ```console go install github.com/superq/smokeping_prober@latest sudo setcap cap_net_raw=+ep ${GOPATH}/bin/smokeping_prober ``` On multi-cpu systems it is typically more efficient to limit the prober to one CPU in order to reduce the number of cross-cpu context switches and packet copies from the kernel to the prober. This can be done with the `GOMAXPROCS` environment variable, or by using container (cgroup) limits. ```console export GOMAXPROCS=1 ./smokeping_prober ``` ## Docker ```bash docker run \ -p 9374:9374 \ --privileged \ --env GOMAXPROCS=1 \ quay.io/superq/smokeping-prober:latest \ some-ping-target.example.com ``` ## Metrics Metric Name | Type | Description ----------------------------------------|------------|------------------------------------------- smokeping\_requests\_total | Counter | Counter of pings sent. smokeping\_response\_duration\_seconds | Histogram | Ping response duration. smokeping\_response\_ttl | Gauge | The last response Time To Live (TTL). smokeping\_response\_duplicates\_total | Counter | The number of duplicated response packets. smokeping\_receive\_errors\_total | Counter | The number of errors when Pinger attempts to receive packets. smokeping\_send\_errors\_total | Counter | The number of errors when Pinger attempts to send packets. ### TLS and basic authentication The Smokeping Prober supports TLS and basic authentication. To use TLS and/or basic authentication, you need to pass a configuration file using the `--web.config.file` parameter. The format of the file is described [in the exporter-toolkit repository](https://github.com/prometheus/exporter-toolkit/blob/master/docs/web-configuration.md). ### Health check A health check can be requested in the URI path `/-/healthy`. prometheus-smokeping-prober-0.9.0/VERSION000066400000000000000000000000061474372005100202430ustar00rootroot000000000000000.9.0
