I a performance monitoring tool that monitors the performance of my servers. I get an alert message every 5 minutes from
the monitoring tool if the queue count increase. The monitor sends an email of NOT-OK when the queue count increases and
another email of OK when the queue count goes to 0 again.
Lately, we have been seeing some NOT-OK alerts for the queue count increasing. It goes back down before the next monitor runs.
I am trying to investigate the reasons for the spikes. I believe that Garbage collection is causing the the queue count to go up.
I looked at a couple of emails from last month where the queue count was more than zero and pulled the data into an excel file.
I highlighted the records where the queue count is increasing. I am trying to determine what is causing the queue to go up.
It could be GC's are performing, it couldn't be user activity, it couldn't thread utilization. I would really appreciate your help in this matter.
