What is Pushgateway?
Prometheus is an amazing tool, but it has limitations. Some of your applications, including batch jobs and ephemeral jobs, may not live long enough for it to find and scrape them. Since Prometheus cannot scrape all jobs, the company developed Pushgateway as a bridge tool. Because you usually cannot push metrics directly to the Prometheus application, you can sometimes use a Pushgateway to deliver the necessary data. When you need monitoring solutions, try Metricfire.
