Telemetry Client

Telemetry collects runtime statistics from the Servers it is installed on, such as CPU and RAM usage, Network utilization or other parameters. By default, the statistics are collected every 10 seconds and sent to an Influxdb backend.

The data can then be used to display graphs and trigger alerts via Grafana.

The data collection is done by a telemetry daemon running on the monitored hosts. We are using telegraf for this task. It's purpose is to collect all metrics defined in a config file, cache them for a short amount of time and transfering them to the time series database via a TCP or UDP network connection.

Requirements

• A telemetry server has to be set up and running on a host, to take the telemetry data. This can be done using the Telemetry server role.
