There are 4 User Defined Data Collector Sets under Perfmon generating CSV file on a daily basis.
In the report a red alert occurs which resembles performance log is greater than 12 hours old and is deemed inactive.
When looked inside the Perfmon they are running fine and generating report.
There is no evidence to RESTART each of the Data Collectors
Any clue that you can IDENTIFY the Error and cause what needs to do for erasing red tick mark which identifies that this is to work.
Before hand thanks
