We've spent a considerable amount of time defining what devices, services, and processes we want to monitor and how we want to monitor them. All that work is for nothing if our monitoring system doesn't have a mechanism to let us know when problems occur. In Zenoss Core, events identify when something happens to one of the devices we're monitoring.
In this chapter, we will:
Use the Event Console to process events
Create event commands through the Event Manager
Test events without affecting the actual device
Map events based on monitoring activity
One word of caution before we begin: Don't confuse events with alerts. In Zenoss Core, alerts notify us, the human, when an event occurs. We'll configure alerting rules in Chapter 7, Collecting Events.
