This server is in charge of monitoring the rest of our infrastructure. It runs InfluxDB to store recorded metrics and Grafana to visualize them and send alerts. Every server (including overwatch itself) runs Telegraf to gather metrics and send them to InfluxDB.
More information about the setup is in the Infrastructure monitoring page.
