Issue:
A user brought to my attention to the error snapshot not displaying more then 2 days of errors when looking back at any time frame past 2 days. I verified that I can only see the errors from past two days no matter the time/data range I select. However, for anything beyond, I can see all other historical data in any time/date range just not the errors.
Environment:
APM 9.7.0.0 EM is running on Windows 2008 as a service.
Cause:
Lack of allocated heap size.
Resolution:
Make changes as following to EMService.conf
# Initial Java Heap Size (in MB)
wrapper.java.initmemory=1024
# Maximum Java Heap Size (in MB)
wrapper.java.maxmemory=2048
to
# Initial Java Heap Size (in MB)
wrapper.java.initmemory=4096
# Maximum Java Heap Size (in MB)
wrapper.java.maxmemory=4096
Then, restart the EM service.
