No, it does not seem to be normal.
You might want to try manually running Database Maintenance to see if that clears up, as that will remove orphaned information from the database.
It is normally ran at 2:15am system time by default - it is weird that it did not clear up.
[Start > Programs > SolarWinds Orion > Advanced Features > Database Maintenance]
To see the logging for the Database Maintenance, you might try to look into C:\ProgramData\Solarwinds\Logs\Orion\swdebugMaintenance.log
Repeated thanks for the pointer. I found the swdebugMaintenance.log files in D:\Program Files (x86)\SolarWinds\Orion, but they all seem to be doing the steps for ResponseTime maintenance (including "Removing orphaned data from ResponseTime") without notifying of any failures.
But the records are still being generated for deleted nodes, and the hourly records still exist for deleted nodes.
Thanks again for your help. But I still need more, if anyone has any more.
If you still have the orphaned information under ResponseTime_Hourly even after the Database Maintenance, it might be that the NodeID is still there?
Can you check the NodeID that corresponds to ResponseTime_Hourly that is having the orphaned data, and thereafter, cross check it against the 'Nodes' table
WHERE NodeID = __
Replace __ with the NodeID that you see in ResponseTime_Hourly orphaned data.
Let me know how that goes.
Thanks again Andy.
I am not finding records for deleted nodes in the Nodes table using your query.
When I try
SELECT count(*) Count, [NodeID]
where NodeID not in (select NodeID from NetPerfMon.dbo.Nodes)
group by NodeID
order by NodeID
I currently get 18 rows. Against the _Detail table, 72 rows. Against the _Daily table, none.
Does that provide any clues?
It is weird that you are not seeing the NodeID in the Nodes table, but are still seeing ResponseTime statistics. The Database Maintenance should have removed it.
Just checking if the output from the query, is the orphaned ResponseTime belonging to the same NodeID, or it involves a few?
I was thinking that it might be a one off issue that might not reoccur after you have dropped those statistics.
Alternatively, you can try upgrading as that will facilitate in fixing of flat-files (as well as updating), and see if there are improvements.
