What can Prometheus do?

Prometheus is an open source monitoring and alerting toolkit for containers and microservices. The project is a hit with lots of different organizations regardless of their size or industrial sector. The toolkit is highly customizable and designed to deliver rich metrics without creating a drag on system performance.

Prometheus (software) Prometheus is a free software application used for event monitoring and alerting. It records real-time metrics in a time series database (allowing for high dimensionality) built using a HTTP pull model, with flexible queries and real-time alerting.

Likewise, how does Prometheus collect data? Prometheus collects metrics from monitored targets by scraping metrics HTTP endpoints on these targets. Since Prometheus also exposes data in the same manner about itself, it can also scrape and monitor its own health. For a complete specification of configuration options, see the configuration documentation.

Regarding this, how does Prometheus work?

The Prometheus server works on the principle of scraping, i.e., invoking the metrics endpoints of the various nodes that it is configured to monitor. It collects these metrics at regular intervals and stores them locally. The nodes expose these over the endpoints that the Prometheus server scrapes.

Is Prometheus accurate?

Prometheus values reliability. If you need 100% accuracy, such as for per-request billing, Prometheus is not a good choice as the collected data will likely not be detailed and complete enough.

How do I monitor Prometheus by itself?

We need to provide some ways to monitor that “only” one Prometheus, maybe: Provide a dashboard to view the status of Prometheus, e.g.: https://grafana.com/dashboards/3662. Allow setting a replicated Prometheus as the cold standby. Pre-define some out-of-box highly sensitive alerting rules.

What are Prometheus metrics?

What is Prometheus Grafana?

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. Prometheus acts as the storage backend and Grafana as the interface for analysis and visualization.

What is Grafana monitoring?
