Number of SessionsĪ similar measure to the request throughput, this metric identifies the number of sessions the server can support at a given time. Request Throughput measures the number of requests the server can handle for a certain unit of time and helps determine your hardware needs. Too many active threads at the same time can slow down the application or the whole server. Additionally, you need to see if a sufficient amount of memory has been freed up. You have to determine the right frequency for running garbage collection, since this is a resource-intensive process. In addition, using as little available memory as possible could decrease your memory needs and minimize costs. This reading is critical because running low on heap memory will cause your application to perform slower. It can even lead to OutOfMemory exceptions. Here are some of the key areas you’ll want to monitor: Memory Usage When checking application performance, there are several areas that provide clues on whether everything is working within ideal parameters.
What metrics can be used to keep tabs on Tomcat performance.How you can set up Tomcat memory monitoring.In this article, you will take a look at: It’s important to know what is relevant to monitor and the acceptable values for the metrics being watched.
Tomcat performance monitoring can be done with JMX beans or a monitoring tool such as MoSKito or JavaMelody. As far as Java applications go, Apache Tomcat is one of the most commonly used servers. Application server monitoring metrics and runtime characteristics are essential for the applications running on each server. Additionally, monitoring prevents or resolves potential issues in a timely manner.
