Anyone tried to catch JVM out of heap space errors?
java.lang.OutOfMemoryError: Java heap space
I can measure memory usage, free memory, total memory and compare these in all sorts of neat ways.
However Integration Server utilizing above 80 or even 99% does not necessarily cause a Java heap space error. Thus I receive a lot of false positive alerts.
Also after a heap space error the Integration Server does not necessarily die, usually it just reports itself online but stops processing. Thus I can catch the issue by checking some other things. But I would like to be able to catch the issue quicker. Currently I know the when things should happen on the IS but it’s like did these 4 things happen in the past 60 minutes, if not- dead.
Any help be most appreciated.
