    HP-UX Net-SNMP Multiple CPU Issue

    djobrien

      I have a number of HP-UX servers running the NET-SNMP agent. These are large boxes with as many as 32 CPU's and 1 TB memory. NET-SNMP is only be polling the utilization of CPU #1 and is constantly reporting high CPU usage. Glance shows the average CPU ~50% while SolarWinds shows >90%. How can I get SolarWinds to monitor all installed CPU's on HP-UX servers? Has anyone else experienced this issue.

       

      Thanks,

       

      Derrick

          What version of net-snmp is the system running? Let's make sure it's at least 5.4, since multi-cpu support was enhanced with that release.

              Version 5.6.1.1.001.

                  This works just fine on HP-UX 11.23 but not servers running 11.31. I have attached a sample snmpd.conf file for one of the newer servers. It's about as simple as it gets.

                  Hopefully the extra details help I'm at a loss to why this is not working.

                  Has anyone got to know how to fix this, even we are getting only 1 CPU value if polling the HP-UX with NET-SNMP.
