# Contributing If you have any issues or ideas for improvement you can contact me in the [CMK forum](https://forum.checkmk.com/) by sending me a direct message to `@thl-cmk` (this is the prefered way) or send an email to _thl-cmk[at]outlook[dot]com_. Please include: - your CMK version/edition - your environment (stand alone or distributed) - the OS of your CMK server(s) - the version of the plugin - the crash report (if any) For SNMP based plugins I migth need a snmpwalk from the device in question. This must contain - .1.3.6.1.2.1.1.1 sysDescr - .1.3.6.1.2.1.1.2 sysObjectID and all the SNMP OIDs used in the plugin. If you run the _snmpwalk_ command, please uses these options _**-ObentU**_ in addition to your snmp options like community, version etc. For example: ``` snmpwalk -v2c -c public -ObentU 10.10.10.10 .1.3.6.1.2.1.1.1 > hostname.snmpwalk snmpwalk -v2c -c public -ObentU 10.10.10.10 .1.3.6.1.2.1.1.2 >> hostname.snmpwalk snmpwalk -v2c -c public -ObentU 10.10.10.10 .1.3.6.1.4.1.2620.1.6.1 >> hostname.snmpwalk snmpwalk -v2c -c public -ObentU 10.10.10.10 .1.3.6.1.4.1.2620.1.38 >> hostname.snmpwalk ```
