How do I refresh my Prometheus config?

Prometheus can reload its configuration at runtime. If the new configuration is not well-formed, the changes will not be applied.

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.

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.: Allow setting a replicated Prometheus as the cold standby. Pre-define some out-of-box highly sensitive alerting rules.

How do I know if Prometheus is running?

You can view things such as the current Prometheus environment (Under the “Status” tab), execute queries using PromQL (Under the “Graph” tab) and see what is currently alerting (Under the “Alerts” tab).

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.

What port does Prometheus use?

In the default configuration there is a single job, called prometheus , which scrapes the time series data exposed by the Prometheus server. The job contains a single, statically configured, target, the localhost on port 9090 .

How does Prometheus scrape metrics?

On the Prometheus server side, each target (statically defined, or dynamically discovered) is scraped at a regular interval (scrape interval). Each scrape reads the /metrics to get the current state of the client metrics, and persists the values in the Prometheus time-series database.

How do I check my Prometheus metrics?

You get the metrics details by querying from the Prometheus's time-series database where the Prometheus stores metrics and you use a query language called PromQL in the Prometheus server to query metrics about the targets.

Why is Prometheus?

Prometheus is a monitoring solution that gathers time-series based numerical data. It is an open-source project started at SoundCloud by ex-Googlers that wanted to monitor a highly dynamical container environment. As they were not satisfied with the traditional monitoring tools, they started working on Prometheus.
