The Art of Monitoring

6 Using collectd events in Riemann

In Chapter 5 we set up monitoring and events in collectd and sent those events into Riemann. Now let’s see how we might use those events for monitoring. We’re going to look at several examples of checks we could create using our collectd events.

• We’re going to check collectd or other processes are running.
• We’re going to replicate some traditional monitoring checks for CPU, memory and disk, to help the transition from that more traditional monitoring model.
• We’re going to learn how to create better checks with more sophisticated logic.
• We’re going to create a host-centric Grafana dashboard displaying our collectd metrics as graphs.
