New Relic

The best thing about this software is that it provides really good deep insights. They provide a feature called 'VM' it provides information regarding garbage collection, heap, memory allocations, object allocations etc.

Error insights and alerts helps you to stay updated with what is currently happening with your application. Their app is also good which provide same features. So, even if you're travelling you can get insights directly on your phone.

Appdex score, RPM and other parameters really help in finding bottlenecks and optimising it.

It also tells which database query is taking more time and which is taking the least & which part of your application is taking more time which actually helps you in building an efficient application.

Sometimes, the metrics they provide in the VM section seems incorrect, although hard refreshing the page solves this problem.

I love this product! I have always had the free tier and it has so much many features. I don't know how they do so much for the free tier. I use the realtime app monitoring (APM) the most, to see current traffic as well as checking for slow apis and why they are slow. The second most used tool is to monitor my actual server (Host). Then of course I can't forget the essential and anxiety removing notification system that will tell me as soon as whatever I don't want to happen and set up an alert for, happens. This has saved me and my customers a few times already. Thank you for a great product! :)

I would love to upgrade to the paid version, but, so far, it is too expensive. I wish there were a starter tier, or even a supporter/love your product tier.

New Relic can be used to monitor system performance by integrating it with your system, written in any programming language, so that New Relic can gather variety of system metrics available. The APIs being used in the system can be profiled using New Relic or be it the queries happening on the system database. This analysis can later help in optimising the system performance by making sure all these slow api hits or db queries are working efficiently.

User interface of New Relic can be enhanced and made more user friendly for new users so that they can start their system analysis straightaway without having to get familiar with the UI first.
