How to measure CPU and memory during load test

Question

We are using JMeter in a heterogeneous environment and we would like to measure CPU and memory while we are producing heavy load on a server where our service or web application is running. What would you recommend to use? Is there any software solution (open source or commercial) available which records CPU and memory usage in a file or to a database?

Thank you!

Answer 1

Perhaps you can take a look to collectd if you run in some unix/linux flavour. It will bring you not only CPU but also memory, Disk IO, network and a good number of plugins available.

Answer 2

One you install the Perfmon plugin, I also had to install the server agent, and open the firewall port 4444.

Here's a link which I found super useful.

Answer 3

You can use our JMeter perfmon plugin to measure CPU, memory and a lot of other metrics:

Answer 4

From the java perspective, you can use jconsole or write your own code to monitor the memory usage.

1. Measure CPU and memory consumption of a Java application
2. javasysmon on github
3. dstat for linux and perfmon for windows. Read more

Answer 5

You could take a look at Cacti.

It could collect resource usages like CPU, MEM easily with built-in templates and display them in nice graphics. Both Windows and Uni* are supported.
