What is server monitoring?
Server monitoring includes various approaches and tools for monitoring the performance of application and web servers. It includes collecting machine- and infrastructure-level metrics that help operations teams understand their infrastructure, but they often fail to find, isolate and troubleshoot performance issues that occur in the in the application code.
What's the problem?
However, most of the server monitoring tools are incapable of knowing how applications are performing. None of the server monitoring tool can explain the following:
Slow part of the application code
The frequency, performance and application functionality used
Exceptions of application functionality
Impact of a slow external service call impact to the application response time a
The response time of each request to my application
The components of application involved in any of transactions to understand the slow down
The way the application code operates in the run time
It is almost next to impossible to restore application service quickly, without answering these fundamental questions.
What's the solution?
To address these queries, most companies adopt log monitoring and analytics as a solution. However, log file monitoring cannot answer many of the questions without a lot of customization. The latest APM tools understand the actual internal workings of your applications - they view the code executing, all entry and exit calls to the application, transactions, exceptions and their associated impact, etc.
Key Benefits of AppDynamics:
View server health and chart application topology
Find and fix performance slowness by drilling down to code level detail
Track important server metrics and trend performance
Ensures end users are not impacted by fixing bottlenecks
What's the impact?
APM products providing a tremendous amount of value. Some of the benefits of using APM:
Quicker QA cycle due to rapid problem isolation,detection, and resolution.
Quick development owing to less time tracking down bugs.
Steady production environment because of better QA and development.
Reducing MTTR from hours/days to minutes.
Fewer bugs released as they are easier to identify and remediate.
