configuration includes an external HDS, you may notice that you are missing
records from reports during the Logger recovery process.
If the Logger
connected to the external HDS goes offline, the external HDS does not connect
to a different Logger. For example, if the external HDS is connected to Logger
A and Logger A fails, the HDS does not connect to Logger B. When Logger A comes
back up, it recovers data from Logger B and begins to receive current
historical information. After Logger A has recovered all of the data from
Logger B, it replicates this data to the external HDS.
If reports are run
from the external HDS for recent intervals while Logger A is offline or while
the Logger is in the process of recovering or replicating data, you might not
see data for those intervals in reports. These records are missing only
temporarily; you will see the data after the replication process for the tables
used by the reports is complete.
If your deployment
does not include an external HDS and Logger A goes offline, you will not see
report data from the interval during which Logger A was offline until Logger A
has recovered that data from Logger B.
