JMX / Java memory pool items

[nairb]

Hello all

I have found some JMX memory items in Zabbix but I'm not sure what they related to each other. For example, for old gen I have:
- Old Gen
- CMS Old Gen
- PS Old Gen

Can you tell me what the difference between each is? Only CMS seems to be getting data

Kind regards

Brian

It depends on the garbage collector you currently use. "CMS" means "Concurrent Mark Sweep", that's the one you use now, that's why you have data for the "CMS Old Gen" and not the others beans for the old memory space.

Clear answer. Thanks for your help
