How to Handle the load on jira application

Srikanth Gogineni

Hi All,

 

I have been facing high cpu usage and i see the load on CPU ( consuming high cpu usage ) when multiple users are trying to create/requests(  using clone-plus plugin ) at a time .

 Jira version is : 6.2.7

No of Active users : 150 

connection pool max size is 150

max idle size is 80 

JVM memory = 18GB ( out of total RAM 32 GB) 

 

Could anyone help on controlling the high cpu usage .

 

Regards

Hi Shrikanth,

 

There are other factors to assess and consider to fine tune the server resources allocation for JIRA application, e.g: custom fields, third-party add-ons etc.

 

Going forward, I would suggest identifying the cause of the CPU spike before we plan ahead:

• Enable GC logging as illustrated in this KB -- How to Enable Garbage Collection (GC) Logging
• Generate thread dumps and CPU dumps when CPU usage spikes: 
  

  for i in $(seq 6); do top -b -H -p $pid -n 1 > app_cpu_usage.date +%s.txt; kill -3 $pid; sleep 10; done

  
  Make sure you change $pid to the process ID of running Jira, before running this command
• Open a Support ticket with JIRA Server Support -- with the support.zip and app_cpu_usage files
