@Named @ThreadSafe public class TaskTimer extends Object implements org.springframework.beans.factory.DisposableBean
Customers need to turn on DEBUG logging for com.codebarrel.jira.plugin.automation.util.TaskTimer This class allows you approximately time tasks across threads and will provide output of stats every SPLITms to DEBUG & optionally, a file. It's quite handy to track how things are performing is high volumne systems. Sample output:

The columns are:

(1) Timestamp (2) Key of the task you're tracking. You can give this anything, so even the issueKey or ruleId, meaning your can group event types (3) # of invocations (4) Total time (ms) (5) Utilization: % of time / the last split. Can be > 100% if multithreaded (6) Invocations / second
