Hi,

we have recognized that we can measure executing variables. The interface
CrawlerControllerPerformanceAgent
doesn't tell us in which unit (seconds or milliseconds) the time is measured.

Hi,

the time is measured in milliseconds.
This information is not part of the interface documentation as there is no guarantee what unit an actual implementation uses.

However, there are usually annotations on the MBean implementation classes like @MeasureUnit("ms"). These are shown when using jconsole. Navigate to Smila/Crawlers/Total/Attributes. There you should see besides others
- AverageDeltaIndicesProcessingTime (ms)
- AverageRecordsProcessingTime (ms)

Bye,
Daniel
