Thread dump export of all entries of e.g. java.util.Hashtable$Entry

[snoerenberg]

Hi,

we are currently facing a problem where we have 2 instances of a cache inside one JVM instance.
One is growing over time, one remains stable.

Is it possible to extract all the entries or keys from both caches using Yourkit?
This would give us a hint where the entries of the larger one are coming from. Of course only happens on production after some weeks runtime.

In the UI I can get only 500 entries displayed and exported but the expected amount is 60 million entries for the large cache.





Thanks

Hi Stephan,

You can increase the limit as described here:

Hi,

I can test it but I assume the UI will not be able to handle 60 million records.

Hi,

the UI is not able to render it, I could only click on "object explorer" and than Yourkit freezes.

Yes, UI is not able to render it, and I belive humans are not able to analyze it. There should be a sort of automatic analysis.

There should be a possibility to export to CSV like in Eclipse MAT.
Afterwards this can be analyzed by awk/sort/... and finally Excel with some Pivot tables.

Thanks
Stephan
