DevOps is a set of practices that basically do the task of automating the processes between software development and IT Teams, in order that they can develop, test and release a more reliable software in a shorter time. To achieve this, DevOps has a fully packed toolbox, with tools ranging from Configuration Management to Integration Management to Delivery Management to Monitoring tools.
In this blog post, we will be discussing Top 22 monitoring tools. It can be easily argued that Monitoring tools are the most crucial and vital part of DevOps. They provide crucial information that helps you to ensure optimal performance. But with so many tools in the market, which tool is cd best suited for your scenario is very difficult to identify.
To help you out in this, we have listed the top 20 monitoring tools in this article. These 20 monitoring tools are divided into 4 categories on the basis of the need they cater.
These categories are:
- Infrastructure Monitoring
- Application Performance Monitoring(APM)
- Network Monitoring
Let’s begin with a detailed discussion on Monitoring Tools.
