Historical report is missing data for a recent interval

A historical report is missing data for a recent interval.

None

This could occur because you are running the report at the end of the last interval (for example
it is 12:31 and you are running a report from the 12:00:00 to 12:29:59 interval). Data replication
from the Logger to the Historical Data Server can be delayed by 1 to 5 minutes. The data for
the last interval might not be in the HDS yet.

This could also be because the Logger connected to the HDS has gone offline or because the
Logger went offline and is now in the process of recovering. When the Logger fails, the HDS
does not switch to the back up Logger. Instead, it waits for its Logger to recover. When the
Logger recovers, it begins receiving current data and recovers data from the back up Logger
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 offline or because the HDS went offline
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.

No action is necessary; the data will appear in reports when the recovery and replication processes
are complete. Try running the report again in several minutes.
