is this caused by upgrade?
From which version you upgraded?
Do you receive a lot of traps or syslogs?
I,m upgrade NPM from 10.4 to 10.5. But I am not sure that it because of an upgrade. I didn't track CPU loading until now.
Comments from techsupport Solrawinds Orion:
"...From reviewing the logs it appears that the Multicast routing is causing problems within the Data Processor.
I have the following suggestions:
** Before doing any work on your database please make sure that you have a current backup as this will make a permanent change to your database. **
Please stop all the Orion Services using the Orion Service Manager (Start > All Programs > Solarwinds Orion > Advanced Features)
Next run this script against your DB:
IF (dbo.GetNpmDbVersion() = 8) -- version is equal to 10.5
IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[NPM_RoutingNeighbor]') AND type in (N'U'))
IF EXISTS (SELECT * FROM sys.indexes WHERE name='IX_NPM_RoutingNeighbor' AND object_id = OBJECT_ID('NPM_RoutingNeighbor'))
ALTER TABLE NPM_RoutingNeighbor DROP CONSTRAINT IX_NPM_RoutingNeighbor
--recreate the unique constraint
ALTER TABLE NPM_RoutingNeighbor
ADD CONSTRAINT IX_NPM_RoutingNeighbor UNIQUE (
Next restart the Orion Services using the Orion Service Manager. Monitor the CPU usage.
If this does not improve we can try disabling Multicast Routing completely:
1) Ensure you have a good back up of your Database.
2) Modify pollers table
Connect to your Database Using SQL Server Management Studio
Right Click on your Database -> New Query...
DELETE FROM Pollers WHERE PollerType LIKE '%Multicast%'
Monitor the CPU usage on the Orion Server.
If this does not help I would recommend upgrading your Orion installation to the latest version 10.6..."
Now I'm upgrade Orion NPM from 10.5 to 10.6, I track CPU loading... while everything is silent
The problem was solved by an upgrade to NPM v10.6.
