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.

How do you implement Prometheus?

Install Prometheus

  1. Create a dedicated namespace for the Prometheus deployment: $ kubectl create namespace prometheus.
  2. Give your namespace the cluster reader role:
  3. Create a Kubernetes configmap with scraping and alerting rules:
  4. Deploy Prometheus:
  5. Validate that Prometheus is running:

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.
