We complement the Netdata agent with Netdata.Cloud, a free-forever SaaS offering that maintains all the principles of the Netdata agent, while providing infrastructure level monitoring and several additional convenience features.
In Netdata.Cloud, infrastructure is organized in war-rooms. On each war-room you will find the "Overview" page, that provides a fully automated dashboard, very similar to the one provided by the agent, in which every chart presented aggregates data from all servers in the war-room! Magic! Zero configuration! Fully automated!
Keep in mind that Netdata.Cloud is a thin convenience layer on top of the Netdata agent. We don't aggregate your data. Your data stay inside your servers. We only collect and store a few metadata (how many netdata agents you have, which metrics they collect, what alarms have been configured, when they triggered - but not the actual metric and log data of your systems).
Try it! You will be surprised!
