[mrtg] MRTG with SNMPv3 and contecxt names - help required.

[Nicoletti, Leandro (CONT)]

I'm trying to graph some stats on a Checkpoint VSX firewall that uses context names for each virtual firewall. I can successfully walk the OIDS using SNMPV3 at the CLI, but having difficulty getting anything into MRTG.

I can successfully pole the interfaces using MRTG and SNMPv3 with context names using the example below, but getting nothing when I try custom OIDS

enablesnmpv3: yes
target[10.10.10.10]: #eth3-02:public at 10.10.10.10:::::3
SnmpOptions[10.10.10.10]: privpassword=>'somepassword',privprotocol=>'des',username=>'someusername',authpassword=>'somepassword',authprotocol=>'md5'
SetEnv[10.10.10.10]: MRTG_INT_IP="No Ip" Some Interface="eth3-02"
MaxBytes[10.10.10.10]: 125000000.

This could be down to my config. I'm trying to capture current and peak connections on a firewall (amongst other things). The basic config looks like this, when I run it I get a 'no response from host'. I'm not 100% sure if my use of SNMPv3 and context names are correct. Any help with this config would be greatly appreciated.

enablesnmpv3: yes

Walk specific OID works ok (connection tables)
snmpwalk -n ctxname_vsid7 -v3 -l authPriv -u someusername -a MD5 -A somepassword -x DES -X somepassword 10.10.10.10 .1.3.6.1.4.1.2620.1.1.25.3
