Monitoring

Starting with version 0.5 RPort comes with basic monitoring capabilities. The RPort client can collect the following metrics from the underlying operating system:

• CPU usage (percent)
• Memory usage (percent)
• IO usage (percent)
• List of running processes
• Fill level of hard disks and mount points

To use the built-in monitoring both – server and client – must run at least RPort 0.5.0.

The monitoring is enabled by default. If newer clients are connected to an old server the client disables the monitoring automatically. All monitoring data is stored on the server in a sqlite3 database file monitoring.db inside the data dir of the RPort server.

Select a proper value for data_storage_days carefully in the [monitoring] section of the rportd.conf. The more clients you have, the more data will be collected. Having hundreds of clients collecting monitoring data, the database file can quickly grow to 10 Gigabytes or more. Use a symbolic link, if you want to store the monitoring.db file outside the data dir.

If you client configuration after an update does not contain a [monitoring] section, copy it from the rport.example.conf. To save bandwidth and disk space on the server, you can disable the monitoring for clients completely. Please refer to the documentation inside the configuration example to explore all options of the monitoring.

All collected monitoring data can be fetched using the API. Please refer to our API docs.

RPort now includes a powerful alerting feature that processes monitoring data. For more info, see the Monitoring Alerting section.
