Introduction

In this lesson, we explore the significance of the Prometheus Push Gateway in monitoring batch jobs. Batch jobs typically run for only a short period before exiting, which makes it challenging for Prometheus to scrape their metrics in time. Without an active process, Prometheus might miss these essential data points.

When a batch job completes, it pushes its metrics to the Push Gateway. Prometheus then scrapes these metrics at regular intervals, just as it does with any other target. From Prometheus' perspective, the Push Gateway functions as a standard HTTP endpoint without requiring any special configuration.

By integrating the Push Gateway into your monitoring strategy, you ensure that critical metrics from short-lived batch jobs are not lost, enhancing the overall reliability and accuracy of your observability system.
