But Prometheus isn’t only a time series database. Prometheus has become the mainstream monitoring tool of choice in container and microservice world. Prometheus exports a long list of metrics that can be seen by browsing to So, how you construct your Prometheus monitoring dashboard will ultimately involve quite a lot of trial and error. monitoring, tutorial You can fine-tune the amount of RAM using the To get an overview of how well Prometheus is performing, we can measure the ingestion rate for the samples using the Likewise, it can be useful to monitor the actual amount of time between target scrapes that you have configured for Prometheus using the Another useful metric to query and visualize is the Grafana comes with a built-in official dashboard for Prometheus called As you can see, this dashboard contains the following visualizations (some are similar to the ones described above):While designed for benchmarking Prometheus servers, the While this is probably overkill for the day-to-day monitoring of your instance, this advanced dashboard includes some useful panels that are not displayed in the Prometheus Stats dashboard.You can slice and dice the various metrics that Prometheus self-reports about itself any way you want. Now we will configure Prometheus to scrape these new targets.

Prometheus acts as the storage backend and Grafana as the interface for analysis and visualization.Prometheus collects metrics from monitored targets by scraping metrics from HTTP endpoints on these targets.

The combination of Prometheus and Grafana is becoming a more and more common monitoring stack used by DevOps teams for storing and visualizing time series data.
about itself at You can also verify that Prometheus is serving metrics about itself by This guide is a "Hello World"-style tutorial which shows how to install, It records real-time metrics in a time series database built using a HTTP pull model, with flexible queries and real-time alerting.
