Why APM is Extremely Significant!
We all have faced the problem when the system gets too slow. Have you wondered why this problem occurs? Well, there could be several reasons but one of them is application performance. In today’s time, the term application has become very large and complex. Users using these applications often choose different mediums, as they have separate goals and requirements as per their needs.
This diversity in consumption medium brings complexity in a configuration which is only increasing in today’s time. Application performance means how available your application is for this real-world which brings us to APM. In this blog, first of all, we will discuss, what is APM, why it is needed, and what are the APM tools, which can help us obtain the information and health of the system.

This blog is a helpful summary of what I learned about logstash and how it helped. So, Ladies, Gentlemen, and others, sit tight and read on.

Logging and monitoring are like Tony Stark and his Iron Man suit, the two will go together. Similarly, logging and monitoring work best together because they complement each other well.
