    SNMP stops polling Orion NPM 9.5 sp3

      Here is a bizare one for you guys :)


      Just installed the lates Orion NPM 9.5 sp3 and running into an odd problem. The historical  data is available for network interfaces but SNMP polling randomly stops for all objects (drives, cpu, memory). You can see real-time stats but no historical data. Also if you look in the polling stats the SNMP OUTSTANDING goes through the roof and SNMP statistics index shows 0 out of %number of polls%. The problem goes away after the server is rebooted or services restarted.


      Its a Windows 2008 Server running on VMWare.

      Tried disabling Anti-Virus

      Windows firewall is off

      CPU and RAM utilization appear to be normal

      Any ideas?

          The issue was related to Windows server 2008. After moving to Windows 2003 server SNMP works correctly. However now the NPM service randomly stops :)

            We are running NPM 9.5 SP4 and have a similar problem in terms of "SNMP OUTSTANDING' going through the roof.  After the poller runs for a few hours we continue to see graphs for status polls but the graphs for interface statistics stop updating and "SNMP OUTSTANDING" shows in the thousands or higher.  Stopping and restarting the poller services fixes it for a while, but then it just happens again.  I know our SQL server is under-powered and I'm trying to get some input from SOMEBODY (Josh? Anybody?) as to what specs of hardware we should shoot for. But even at times when the SQL server is doing pretty well, we keep "losing" the interface statistics graphs.  Any ideas?
