Summary

As a final word of caution, remember that successful health checks across a cluster do not equate to a positive end user experience. Make sure to be in communication with end users about their experience, and use the cluster for your own purposes to ensure you are familiar with the experience the end user is receiving.

In this chapter, we have gone through a list of items that should be checked to monitor the health of an OpenStack cluster; this list is not exhaustive though. The best practice is to keep an eye out for possible points of failure and add checks that make sure that something that could potentially degrade services is monitored for its health.

The last topic for us to cover is troubleshooting. When these health checks start to alert, how should you go about diagnosing the problem and resolving the issue? In the last chapter, we will take a look at how to troubleshoot each of OpenStack's components.
