How do I update Prometheus config?
Prometheus can reload its configuration at runtime. If the new configuration is not well-formed, the changes will not be applied. A configuration reload is triggered by sending a SIGHUP to the Prometheus process or sending a HTTP POST request to the /-/reload endpoint (when the –web. enable-lifecycle flag is enabled).
How do I reset my Prometheus service?
killall -HUP prometheus # or: systemctl reload prometheus journalctl -eu prometheus # check the logs! If the new config is bad, prometheus will log an error and keep running with the old configuration. If the new config is good, it will log success and start using the new configuration.

How do Prometheus exporters work?
Exporters are essential pieces within a Prometheus monitoring environment. Each program acting as a Prometheus client holds an exporter at its core. An exporter is comprised of software features that produce metrics data, and an HTTP server that exposes the generated metrics available via a given endpoint.
What is Grafana tool?
Grafana is an open source solution for running data analytics, pulling up metrics that make sense of the massive amount of data & to monitor our apps with the help of cool customizable dashboards. The tool helps us study, analyse & monitor data over a period of time, technically called time series analytics.
How do I run node exporter in the background?
Running Node exporter in CentOS 7 is very straightforward. Download node exporter package and untar the package. It is always better to rename the folder for better management. Node exporter has to be run always in the background to collect the metrics and expose the metrics as http to be scraped by Prometheus.
How does Prometheus work?
Prometheus can scrape metrics from jobs directly or, for short-lived jobs by using a push gateway when the job exits. The scraped samples are stored locally and rules are applied to the data to aggregate and generate new time series from existing data or generate alerts based on user-defined triggers.
What is Prometheus Pushgateway?
The Prometheus Pushgateway allows you to push time series from short-lived service-level batch jobs to an intermediary job which Prometheus can scrape. Combined with Prometheus’s simple text-based exposition format, this makes it easy to instrument even shell scripts without a client library.
