Pinned topic A confusing metric in Health Center

‏2012-11-14T19:45:42Z |
I use IBM Health Center to analyze my java program.
In the "Locking" analysis page, there is a metric named "%util"
%util: The amount of time the lock was held, divided by the amount of time the output was take over.

What the meaning of "the amount of time the output was take over"? And what the "%util" metric is referred to?

    Hi,

    The time the output was taken over refers to how long the application has been monitored for (normally the lifetime of the application). So %util is the percentage of the time that the lock has been held for over the lifetime of the application.

    So, for example, a value 14% would mean that a lock had been in use for 14% the time that we have monitored Things like cropping etc on the data can reduce this time window.

    Regards
