Prometheus
Prometheus is an open source monitoring tool that was originally built by SoundCloud in 2012, inspired by Google's BrogMon. It is written in GoLang. According to the New Stack Survey of 2017, Prometheus is one of the most widely used tools for monitoring Kubernetes clusters. What makes Prometheus different than other open source monitoring systems is that it has a simple, text-based format, making it easy to get metrics from other systems. It also has a multidimensional data model and a rich and concise query language. Using Prometheus, we can monitor all levels, nodes, container-scheduling systems, and also routers and switches. If we are dealing with large applications and a fast-moving infrastructure, this means that the jobs that we run change rapidly and we have to deploy them around 100 times a day. In this case, Prometheus will be very useful, as it has the ability to discover services. If we have a dynamic infrastructure, we can use Prometheus to detect early failures...
