RMON enables you to check the availability of your services, measure application response times, perform various types of checks, receive notifications regarding SSL certificate statuses, etc. You can install RMON on multiple servers, and agents will retrieve checks from the first responding server, sending results sequentially to the first accepting server.

Read more about Agents here.

You can also configure the storage of Checks metrics in VictoriaMetrics and display them in RMON. Read more about using VictoriaMetrics with RMON here.
