    NPM Polling problems

      Hi I am wondering if someone can provide me with some pointers on how to troubleshoot some polling problems I am having.

      My Configuration

      NPM 9.1 SP5

      Three Pollers on VM's with the Web Console on one the VM's with the Poller

      # of Elements

      Poller with Web Console - 4556

      Poller 2 - 1704

      Poller 3 - 4637

      SQL Server -- Dedicated Server - Microsoft SQL Server 2005 - 9.00.3042.00 (X64)

      Database size info-

      total Space usage - 112 gigabytes

      Data Space usage - 42.3 gigabytes

      Index Space usage - 1.0 gigabytes

      Free Space Available - 68.2 gigabytes

      Database volume is on a SANS


      looking at the graphs for interfaces-- I am seeing gaps-- The sampling rate is currently set to the default of 10 minutes. If I look at the the Polling Engines Stats there are times when the polling engines appear to be down --- i.e the polling engine "icon" is red.

      The problem I having is whether this is a database problem or a network problem or something else.  I have used the "polling tuner" to size the poll rates and I still see occasional problems. Today has been especially been a problem

      Any help would greatly be appreciated...

          Hi charpham,

          I have experienced it before and perform the ff test

          1. Check if the polling engine is with the same version with the primary server

              start > progam files > solarwind orion > advanced features > monitor polling engine

              if not. download the new version on the customer portal and apply it to all polling engine

          2. Check if all services on each polling engine is running. If one service is in stopped mode then you can see the polling engine in red on your monitor polling engine

              start > program files > solarwinds orion > advanced features > Orion service manager).

               i.e syslog services. do take note that in NPM 9.1 SP5 Alert manager by default is stopped in all polling engine except on your primary server or web server

          3. Restart the polling engine 

          4. Review polling completion percentage ( http://www.solarwinds.com/support/orion/docs/gaps/gaps.htm )

          1. Log on to the Orion server.
          2. Click Start > All Programs > SolarWinds Orion > Database Utilities > Database Manager.
          3. Expand your Orion database in the left navigation tree, and then click Engines.
          4. Click Table > Query Table in the menu bar.
          5. Type Select PollingCompletion from Engines in the Query window, and then click Refresh.

          5. Try to stopped and restart the solarwind network performance monitor and solarwind syslog services on Monitor Polling Engines. It will take some time before it goes to running state because of synchronization with the database


          Hope it will help
