Prometheus is an open source monitoring and time-series database (TSDB) designed after Borgmon, the monitoring tool created internally at Google for collecting metrics from jobs running in their cluster orchestration platform, Borg. The following image shows an overview of the Prometheus architecture. In the center we have a Prometheus server, which is the component responsible for periodically collecting and storing metrics from various targets (e.g. the services you want to collect metrics from). The list of targets can be statically defined in the Prometheus configuration file, or we can use other means to automatically discover those targets via Service discovery. For instance, if you want to monitor a service that's deployed in EC2 instances in AWS, you can configure Prometheus to use the AWS EC2 API to discover which instances are running a particular service and then scrape metrics from those servers; this is preferred over statically listing the IP addresses for our application in the Prometheus configuration file, which will eventually get out of sync, especially in a dynamic environment such as a public cloud provider. Prometheus also provides a basic Web UI for running queries on the stored data, as well as integrations with popular visualization tools, such as Grafana.
