Please post a query that yields this error.
can be triggered by running a number of queries usually as they become more complex but for example the one you gave me will also trigger it.
MAX(I.Traffic.InMaxbps) AS InMaxBps, AVG(I.Traffic.OutMaxbps) AS OutMaxBps
FROM Orion.NPM.Interfaces I
WHERE I.Traffic.ObservationTimestamp > GETUTCDATE()-30 AND I.InterfaceID IN (
SELECT TOP 10 T.InterfaceID
FROM Orion.NPM.Interfaces T
WHERE T.Traffic.ObservationTimestamp > GETUTCDATE()-30
GROUP BY T.InterfaceID
ORDER BY AVG(T.Traffic.Averagebps) DESC
GROUP BY I.NodeID, I.InterfaceId, I.Node.Caption, I.Caption, CONCAT(YEAR(I.Traffic.ObservationTimestamp),'-',MONTH(I.Traffic.ObservationTimestamp),'-',DAY(I.Traffic.ObservationTimestamp))
Sorry for the late reply - I lost track of this thread.
That query works for me if I add the "SELECT" at the beginning, though I know from your other thread (SWQL Complex query ) that you are on an older version of the platform - you might be hitting some bug we fixed years ago.
To get more details about the error, you can look in the SWIS log file: C:\ProgramData\SolarWinds\InformationService\v3.0\Orion.InformationService.log
