Netflow Event Errors

Hello,

I am seeing a large amount of errors in my event logs from netflow that state the following:

Event Type:   Error
Event Source:   NetFlowService
Event Category:   None
Event ID:   0
Date:       2/21/2008
Time:       1:49:29 PM
User:       N/A
Computer:
Description:
Exception: error occurred during packet processing. Object reference not set to an instance of an object.

I did a search and it is a bug apparently and the solution was the following:

here is a bug fix in the works for this, but in the meantime, running this query should get the messages to stop.

INSERT INTO PortsProtocols
 SELECT ServicePorts.Port, -1 FROM ServicePorts
 WHERE ServicePorts.Port NOT IN
 (
 SELECT PortId FROM PortsProtocols WHERE PortId=ServicePorts.Port
 )

GO

What exactly does "run this query" mean? In the database manager?

I am getting that same error, and none of my NetFlow data is displaying on the web interface. I dont know if its being imported into that database either not that I care. I just use NetFlow for realtime troubleshooting. I have a case open right now with support. I had to run the Diag utility and get it sent to the development team. Sure would be nice to have NetFlow back.

I am trying to think of anything that might have caused this today. So far the only changes I made were.

Implement QoS on MPLS network
Add more ports to NetFlow
Updated IP address ranges

I dont think any of those tasks should have created any problems.

Have you checked in perfmon the SolarWinds counters, and see what your "Netflow Invalid Packet Count" is? Ours is going through the roof here, and we are getting all those Application Log errors.

Yes you would run this in either Database Manager or SQL Management Studio for SQL Server 2005 or Query Analyzer for SQL Server 2000.

#2 may have caused this because of a bug. Have you tried the SQL query posted above? I think that will fix the errors for you.

Great. That query fixed everything right up. Even the problems I was having with the web interface not displaying any data. Thanks.
