Summary
We have only scratched the surface with regard to monitoring and troubleshooting. Monitoring and Azure Monitor deserve their own book in order to do them any justice.
In this chapter, I began by introducing the concept of monitoring, discussing why monitoring is important and what SLIs, SLOs, and SLAs are. Then, I introduced the concept of troubleshooting and discussed my thought process and how I break down problems.
The rest of the book then focused on the key metrics and logs available to us for ADX and demonstrated how to enable diagnostics, and then we walked through an example and troubleshot an issue where data ingestion was not working.
Finally, we learned how to configure alerts for ingestion failures. We configured an action group that would send an email and an SMS whenever the ingestion failed.
In Chapter 10, Azure Data Explorer Security, we will learn how to secure our ADX clusters.
