When I checked the archived values via event count I can able to see the arc off line values but can't see arc off line values when I check start time and end time. Any specific reason?
This could be related to the WI 176390 - Arc-offline markers appear for backward search queries when the search period spans over archives with no data for the tag
Arc Off-line marker is returned when doing backward search and the search period spans over archives which do have primary record created but do not contain data for the tag.
Set MarkArchiveGaps tuning parameter to either 0 or 2. Restart of PI Archive subsystem is required to apply the change
0 – No gap markers
1 – Gap markers when there is actual gap between archive AND/OR when the point has no value during a whole archive (default)
2 – Gap markers ONLY when there is an actual gap between two consecutive archives.
