README.md

System Monitor

Java based system monitoring solution with support for plugins.

Example dashboards are provided in the doc/ folder, which can be imported into your Grafana installation.
Screenshots are available in the downloads section.

Components

Client

Runs on your hosts and collects metrics, which are sent to the central server.

More information.

Server

Receives aggregated metrics from clients and saves these into InfluxDB.

More information.

Plugins

Loaded by the client and provides extensions for doing the actual collecting of metrics.

More information.

Known problems

Correct timezone and clock

Ensure you have correct timezone and date/time and NTPd (or similar) running to keep it accurate!

Naming collision

You can't have hosts with the same name, as these cannot be distinguished when metrics are written to InfluxDB (which uses the hostname as key).

Renaming hosts

If you rename a host, the metrics in InfluxDB will still be available by the old hostname, and new metrics will be written with the new hostname. There is no easy way to migrate the old data, but you can delete it easily:

USE sysmon;
DELETE WHERE hostname = 'unknown';
