Low Collector Memory Incidents

Hi all,

A lot has been written about this, but I have a question about this same problem that I am suffering, "The Collector allows only uninstrumented agent connection for Agent 'XXX' due to low collector heap memory (heap usage: 87%)."

Our collectors (7), are in a Collector Group, have 16GB RAM and the same configuration

-Xmx2G

-Xms2G

-XX: MaxPermSize = 256m

-XX: PermSize = 256m

To set -Xmx4G could help us solve the problem? It's AppMon 6.5

Best Regards,

Juan

Hello Juan,

That is correct. No matter how much memory you have available on the Collector machine, unless you change the Xmx and Xms values, it won't matter.

I think setting it to 4G would be a good start. Remember that you will also have to restart the collector once you make the change for it to take effect.

Let me know if you have any questions.

Thanks,

Ari

Thank you very much, Ari. For begining, we will set that. Although it will be slow to check the result, we will post it here.

Best Regards,

Juan
