Any way to view historical load information in DB such as in the Process and Memory Viewer UI

    JVM memory (Windows and Linux) and CPU utilization (Linux only) is written to the memory-diagnostic.log within <install home>/logs/<JVM>/<product>/ (such as .../logs/IA/IA/). This log contains snapshots every three minutes. Since it writes one line per three minutes, this log doesn't rollover frequently and would contain a sizeable chunk of historical data. This is enabled by default, so you'll already have historical information in your system.

    Here's a sample of one of my idle Assure instance's memory-diagnostic.log:

    Ok, I see. Very nice. I didn't even think about that location. Thanks for the quick response!
