monitord

monitord ... know how happy your systemd is! 😊

We offer the following run modes:

• systemd-timer (legacy cron would work too)
  • Refer to monitord.timer and monitord.service unit files
  • Ensure no daemon: mode options are set in monitord.conf
• daemon mode
  • Enable daemon mode in configuration file
  • Stats will be written to stdout every daemon_stats_refresh_secs
• promethus-exporter daemon
  • Recommended to use monitord.service + set a non 0 prometheus_exporter in monitord.conf

Open to more formats / run methods ... Open a PR.

INFO level logging is enabled to stderr by default.

Install

Will work on this, but at the moment it's a manual clone and build from this repository.

Config

monitord can have the different components monitoted. To enable / disabled set the following in our monitord.conf. This file is ini format to match systemd unit files.

```ini [monitord] debug=false

onetime run (cron/systemd timer) output format

Supported: json, json-flat, json-pretty

output_format=json

Run as a daemon or now

Time to refresh systemd stats in seconds

Daemon mode only

daemonstatsrefresh_secs=60

[journald] enabled=no

[networkd] enabled=true linkstatedir=/run/systemd/netif/links

[units] enabled=no

Daemon Mode options

[daemon:prometheus_exporter]

We recommend TCP port 1 due to this monitoring PID 1 :)

Set a port >= 1 to listen

port = 1 ```

Output Formats

json

Normal serde_json non pretty JSON. All on one line. Most compact format.

json-flat

Move all key value pairs to the top level and . notate compononet + sub values. Is semi pretty too + custom. It's all unittested ...

json-pretty

Normal serde_json pretty representations of each componoents structs.
