I need know because the metric "Data Points Retrieved From Disk Per Interval" sometimes present negative values. Can you help me?
This metric should never go negative. Was there any other point back in time that it went below 0? Please open up a Support issue, upload the screenshots as you did here and also the MOM and Collector logs. This will require some deeper investigation.
From my look at the code and our knowledge base, this appears to be an underdocumented metric. Will ask internally for others to respond
Definition of the metric:
Cluster Supportability Metrics - CA Application Performance Management - 10.0 - CA Technologies Documentation
Data Points Retrieved From Disk Per Interval
The number of data points that are retrieved from SmartStor per interval.
Can you post a screenshot of the full screen of the Investigator? We would like to see the full metric path as well.
What version is your MOM and Collectors?
Check the date/time that the metric appears negative and then check the MOM and Collector logs at that point in time to see if there are any warnings or errors.
the version of environment is 10.2.
In Log of MOM and Collectors not has any message.
Please, look this example:
Marking Matt as correct. Please open a case. Once resolved, if desired please share the solution here to help others. I am looking forward to hearing about your progress
