Detect proactively whether application’s memory is under-allocated

 When the application’s memory is under-allocated, it will result in the following side-effects: 

 a. Transactions response time will degrade

 b. CPU consumption will spike up

 c. OutOfMemoryError will be thrown

Only when OutOfMemoryError is thrown, most of us start to look at our application’s memory settings. This is like only when a patient goes to a critical condition; we begin to give treatment :-). 

In this post, let’s discuss how to detect whether your application’s memory is under-allocated or not in a proactive manner.

Garbage Collection Patterns to predict outages

As the author of GCeasy – Garbage collection log analysis tool, I get to see few interesting Garbage Collection Patterns again & again. Based on the Garbage collection pattern, you can detect the health and performance characteristics of the application instantly. In this video and the post, let me share few interesting Garbage collection patterns that have intrigued me.

Is today’s microservice more bloated than yesterday’s monolith?

I am slightly hesitant to write this post, as it might attract some criticism. Nevertheless, I told myself there is nothing wrong with sharing my point of view (even though it might not be well accepted). I would like to share my personal experience regarding yesterday’s Monolithic and today’s Microservice architecture in this post.

Overhead added by Garbage Collection Logging

Enabling Garbage collection logs on your application has certain advantages. In nutshell, Garbage collection logs will facilitate you to optimize Garbage Collection pause time, improve overall application’s response time, forecast production outages, reduce computing cost. Even though Garbage collection logs have these advantages, we weren’t sure what overhead does garbage collection logging add to the application. Thus we set out to conduct the below case study.

“I don’t have to worry about Garbage collection” – Is it true?

I have heard a few of my developer friends say: “Garbage Collection is automatic. So, I do not have to worry about it.“ The first part is true, i.e., “Garbage Collection is automatic” on all modern platforms – Java, .NET, Golang, Python… But the second part i.e., “I don’t have to worry about it.” – may not be true. It is arguable, questionable. Here is my case to showcase the importance of Garbage Collection:

How many millions of dollars enterprises waste due to Garbage collection?

We truly believe enterprises are wasting millions of dollars in garbage collection. We equally believe enterprises are wasting these many millions of dollars even without knowing they are wasting. Intent of this post is to bring visibility on how several millions of dollars are wasted due to garbage collection.
