for the time it was down. Once data recovery is complete, the Logger begins to send the recovery
data to the HDS. Report data for the selected interval is available once the Logger has completed
recovery and the data is replicated to the HDS.
This problem could also occur if the HDS has gone ofine or because the HDS went ofine
and is now in the process of recovering. If it is recovering, data for the selected interval will be
available when recovery for that interval is complete. If the HDS has failed, the data for that
interval will be available when the HDS comes back up and completes recovery for that interval.
In either case the data is still on the Logger and is not lost.
Action:
No action is necessary; the data will appear in reports when the recovery and/or replication
processes are complete. Try running the report again in several minutes.
Data is missing from the Historical Data Server after it has recovered from a failure
Symptom:
Historical data is missing from the HDS.
Message:
None
Cause:
This could be because your Logger data retention and Historical Data Server backup schedule
are not in sync. You should plan these two schedules together so that you retain data on the
Logger for the period in which the HDS is not backed up. For example, if you are retaining data
on the Logger for 2 weeks, you should back up the HDS, at the minimum, once every two weeks.
This way, if the HDS fails, it can recover past data up to the last two weeks from a previous
HDS back up and data for the last two weeks from the Logger. If you are backing up the HDS
every two weeks but storing data on the Logger for only a week, you will be missing a week of
historical data if the HDS fails or the database has become corrupted.
Action:
Change the data retention on the Logger or backup schedule for the HDS to avoid this issue
