SNMP errors and "-nan" in all graphs on HP-UX host.

[cparlam]

Hello,

We have a Cacti 0.8.7i installation (on Ubuntu), monitoring 137 servers, mostly Red Hat Linux and HP-UX. Most of the hosts are being monitored just fine.

Anyway, when trying to add a new HP-UX host (we have a HP-UX host template that works perfectly), I'm getting some weird SNMP errors (SNMP configuration for this host is the same as on similar servers):

CMDPHP: Poller[0] Host[339] DS[9509] WARNING: Result from SNMP not valid. Partial Result: U

When manually snmpwalk'ing from Cacti server:

#snmpwalk -v 2c -c cacti hpuxhost .1.3.6.1.4.1.11.2.3.1.1.15.0
iso.3.6.1.4.1.11.2.3.1.1.15.0 = No Such Object available on this agent at this OID

I have been googling and searching the forum for possible solutions to no avail

Well, I found out what was happening, for some reason SnmpMib2 wasn't started on the host. There are several SNMP-related "daemons" that need to be started on HP-UX:
