Prometheus is an open source monitoring system for which Kopano offers an exporter for kopano-server, kopano-dagent and kopano-spooler.
The prometheus-kopano-exporter accepts data from a unix socket, which it creates on startup and can be specified by passing the --listen-socket argument (or prometheus-kopano-exporter.cfg).
kopano-server or other deamons need to be configured to send statistics data to prometheus-kopano-exporter by setting statsclient_url to the socket created by prometheus-kopano-exporter and by setting statsclient_interval to a lower value than the prometheus scraping interval.
An example Grafana dashboard is available in the Grafana folder and can be imported using Grafana's webui through "create" => "import" => "upload .json file".
