leak analysis memory snapshot automatically triggered settings capture string 6.5 appmon

On our pre-prod systems, we configure automatically Memory Snapshot on Out-of-memory, allowing us to analyse cause of memory (over-)consumption. (java agents)
Before (in 6.3) this Leak Analysis automatically had String capture on, while since migration to 6.5, no Strings are captured anymore.

In System Profile, advanced setting of agent mapping, you can indicate whether you want this feature to be activated. But no possibility for indicating strings to be captured
Is this a change in default setting and can we configure string capture again ?

Regards

Monique

Hello Monique,

This feature requires minimum Java 6 version in the 6.5 AppMon.

Resource Exhausted Notifications (only available when Java is enabled for System Profile): Enable/Disable automatic generation of a Leak Analysis Memory Snapshot in case a Java 6 VM reports an Out-of-Memory notification. This option is not visible if you didn't select Java on the General pane of the System Profile, and enabling it only affects Java agents.

Regards,

Babar

Babar,
this is not an answer to my question.
Java version is > 6, Resource exhausted notification works.
But since upgrade to 6.5, I do not have string capture anymore, what was working fine with 6.3.

Hello au,

Double click on the system profile or right click and edit and then under the agent group select the agent mapping then select the agent name then click on the advanced on the same screen and you will see the following check box there.

According to our guardian, the string capture is removed from the automatic action in 6.5, as this resulted in huge memory-dump
