Monitoring, or the newer term ‘observability’ is a frequently misunderstood subject. I know this because I see forum posts where person A will ask a question and persons B, C and D will reply with some random nonsense. The landscape of monitoring tools is immense so a comparison blog that covers everything would quickly get tedious.
What I’ll do instead is explain the three types of monitoring that you need. Then suggest the best tool to use in each case for Kubernetes. As you may have guessed from the title we’ll cover Time Series, Logging and Tracing.
