SNMP newbee question

I want to start monitoring my Zywall 70 router / vpn builder with check_snmp
The zywall has its own mib file. Where must i place the mib file on the nagios server ?

The main things i want to monitor are the cpu utilization and how many VPN’s are up
For the cpu is the oid .1.3.6.1.4.1.890.1.6.1.1.1 “Show device CPU load in %, it’s the snapshot of CPU load when
getting the values.”

But when i enter this command
/usr/lib/nagios/plugins/check_snmp -H xx.xx.xx.xx -C public .1.3.6.1.4.1.890.1.6.1.1.1

I get this error
SNMP problem - No data received from host
CMD: /usr/bin/snmpget -t 1 -r 5 -m ‘’ -v 1 [authpriv] xx.xx.xx.xx:161

i gues it has to do with the missing mib file

Let’s first check the obvious. Does the following return anything?

or

(assuming 10.15.36.40 is the IP of your ZyWall)

Both commands return this output

SNMPv2-MIB::sysDescr.0 = STRING: ZyWALL 70
SNMPv2-MIB::sysObjectID.0 = OID: SNMPv2-SMI::enterprises.890.1.6
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (714770600) 82 days, 17:28:26.00
SNMPv2-MIB::sysContact.0 = STRING:
SNMPv2-MIB::sysName.0 = STRING: MyZyWall70
SNMPv2-MIB::sysLocation.0 = STRING:
SNMPv2-MIB::sysServices.0 = INTEGER: 14

Good! 8)

Have you tried adding a SNMP version setting?

I didn’t but now i tried :mrgreen:
Unfortunately the same problem.

SNMP problem - No data received from host
CMD: /usr/bin/snmpget -t 1 -r 5 -m ‘’ -v 2c [authpriv] xx.xx.xx.xx:161

I think I found the reason. And a possible fix…

For some reason in the plugin… the default value for the miblist is commented out. Effectively the -m parameter ends up with a ‘’ instead of ‘ALL’.

the quick fix is to hand-edit the check_snmp.c file in the nagios-plugins-1.4.11/plugins folder and change this line:

to this:

& remake/reinstall it.
That should be on line 178.

Does anyone know why it was left commented out?

Alternatively… you can specify the “-m” parameter & put “ALL” in there if required.
