[Check_mk (english)] Dual: Check_MK Agent + SNMP with v1

Hi list,

maybe someone already did that.

I have an appliance which is incapable of giving me the right data when using version 2c (thanks oracle) so I am stuck to use version 1

Additionally I want to monitor the device with an agent so I changed it to “Dual: Check_MK Agent + SNMP” but this will automatically change it to version 2c

Any idea on how to change this behavior?

Hello Mathias,

this is done by rules:

in rules search for SNMP

Check the inline help

You should create a new tag and ad the rule also in that section:

Hosts
using SNMP bulk walk (enforces SNMP v2c)

Most SNMP hosts support SNMP version 2c. However, Check_MK defaults to version 1, in order to support as many devices as
possible. Please use this ruleset in order to configure SNMP v2c for as many hosts as possible. That version has two advantages: it supports 64 bit counters, which avoids problems with wrapping counters at too much traffic. And it supports bulk walk, which
saves much CPU and network resources. Please be aware, however, that there are some broken devices out there, that support bulk walk but behave very bad when it is used. When you want to enable v2c while not using bulk walk, please use the rule set snmpv2c_hosts
instead.

Regards

Alexander Wilk

This enforces v2c – I need v1 with Dual-Check
