 For server configuration and setup we use puppet for most servers. The main puppet code is provided in GitLab <https://gitlab.gwdg.de/dariah-de-puppet>. The DARIAH-DE and TextGrid Repository module (dhrep) is contained in Github <https://github.com/DARIAH-DE/puppetmodule-dhrep>.

+To view real time metrics from our servers or applications we use [Grafana](https://grafana.com/), which is available at <https://metrics.gwdg.de> inside GoeNet.
+Grafana retrieves its data from influxdb. [Telegraf](https://github.com/influxdata/telegraf)can be used to store data from the servers in that database. It is easy to enable telegraf on puppet configured servers. Telegraf stores metrics from the server in the influxdb. 
+
+Some system stats monitored by telegraf in our current puppet setup:
+
+* CPU
+* Memory
+* Space
+* Apache
+* ...
+
+A list of stats telegraf collects stats with the input plugin, a list is [available](https://github.com/influxdata/telegraf#input-plugins).
