What is Push Gateway?
Consider Pushgateway as a metrics mailbox. Prometheus typically gathers metrics from your various services and machines on its own. Yet, some objects, like temporary jobs, are not always capable of sending measures directly to Prometheus.
Basically, Pushgateway acts as a mailbox for these jobs to deposit their measurements. Prometheus then visits, checks the mailbox and gets those metrics. In this manner, your monitoring system incorporates even difficult metrics from contract work!
How to use Prometheus to Monitor Docker Containerized Applications
Containerization has transformed software development by providing portability and consistency through platforms like Docker. Yet ensuring the health of those containerized applications requires monitoring. Prometheus is a monitoring tool that uses its powerful features to monitor the application and make sure that the application is in good health. In this article first, you will understand what is, and then I will guide you through the steps to monitor your Docker container by using Prometheus.
