SCOM DWH performance collection Issue -- error with event ID 31553

  • Article

i have encountered an issue with performance collection inserting in to SCOM DWH. i see the event ID 31553 flooding in OpsMgr log with below errors. im still trying to find the exact cause for the error. however, i have fix the mentioned issue.

i suspect that this behavior occurs when the servers are moved to different domain/change n IP address and this information could not updated in DB.

Solution:

Note: Please make sure you take the latest back of OpsDB and OpsDWH.

**Steps1:**execute following query:

--Get Duplicate Keys in ME Stage from DWH

select * from ManagedEntityStage mes

inner join ManagedEntity me on mes.ManagedEntityGuid = me.ManagedEntityGuid

inner join ManagedEntityProperty mep on me.ManagedEntityRowId = mep.ManagedEntityRowId

where mep.FromDateTime = mes.ChangeDateTime

order by mep.ManagedEntityRowId

Note: when i executed the query i got approx. 10000+ records.

**Steps2: ** Execute following query to delete the records.

--If duplicate keys exists use below query to delete the keys.

delete mes

from ManagedEntityStage mes

inner join ManagedEntity me on mes.ManagedEntityGuid = me.ManagedEntityGuid

inner join ManagedEntityProperty mep  on me.ManagedEntityRowId = mep.ManagedEntityRowId

where mep.FromDateTime = mes.ChangeDateTime
