DGOK5031 No performance data exist for any database of the monitored instance.

Explanation
No database is configured for monitoring, or the
monitored instance has not been set up to store history data in the
Performance Warehouse, or the monitored instance has been set up to
store history data but the end of the first storage interval has not
been reached.

User response
Ensure that you have added databases for monitoring to your monitored instance during
    configuration of the Data Server (peconfig). Further, from Performance Expert Client, check the properties of the monitored instance whether
    the storage of history data is enabled. Finally, determine whether sufficient time has elapsed
    to allow for the completion of at least one storage interval. If required, allow for some extra
    time and try again later.
