Too Long; Didn't Read
Modern systems today are far more complex to monitor. Microservices combined with containerized deployment results in highly dynamic systems. Monitoring systems need to provide integrations with a large and dynamic ecosystem of third-party platforms to provide complete observability. In order to meet these challenges, modern systems had to gear up with new capabilities. In this post, I will look at the characteristics of modern systems and the new challenges they raise for monitoring. I will also discuss common solutions for monitoring, from the days of Graphite and StatsD to the currently dominant Prometheus.
