Need help with an own created ow-server snmptt trap conf

[skyerjoe]

Hello everybody

We plan to integrate an Sensor in our IT Envirionment based on 1-wire sensors with an ow-server.

Unfortunatley the Company which has build the Ow-Server doesn't offer any traps in the MIB.

So i tried to create an MIB trap on myself

My reference is the Main Doku from snmptt

Here is the nagios trap log:

Code: Select all

trap.log:
 Mon Jul 9 11:28:33 2012: Unknown trap (.1.3.6.1.4.1.31440.0.6) received from 192.168.23.10 at:

Here is the snmptt conf for the trap:

Event wateralertBOWSERVER .1.3.6.1.4.1.31440.0.6 "Status Events" Critical

works:
- Other snmp traps which were generated by snmpttconvertmib and used with the snmp check result plugin


dosen't work:
- The own generated trap ( won't be recognised anymore the trap apperars in the unknown trap log all the time)


I think it has sth. to do with the match variable. But I'm not so familar with the perl syntax.

May someone could help me.

no one?

how i have to configure snmptt to identify this trap ...

edit: here is my snmptt.ini: http://pastebin.com/0akpvq1v

I have solved the problem.

First i modified the snmptt.config in a following way:

Code: Select all

EVENT wateralertOWSERVER .1.3.6.1.4.1.31440.0.6 "Status Events" Testing
FORMAT Water Status  
EXEC /usr/local/nagios/libexec/submit_check_result localhost "Water Alert level 1" 2  "Water status is $1-10 $+10-+10  " ( the dollar signs write in this way $1 $2 $3..etc $+1 $+2 ...etc) 
MATCH $+1:(31440.2.2.1.1.4:2)
SDESC
ow-server alert
EDESC

now i can see in the plugin output which Variable defines which Value
so now i can build the final trap:

Code: Select all

[code]EVENT wateralertOWSERVER .1.3.6.1.4.1.31440.0.6 "Status Events" Testing
FORMAT Water Status $+1
EXEC /usr/local/nagios/libexec/submit_check_result localhost "Water Alert level 1" 2  "Water status is  critical"
MATCH $+1:(31440.2.2.1.1.4:2)
SDESC
ow-server alert
EDESC



EVENT wateralertOWSERVER .1.3.6.1.4.1.31440.0.6 "Status Events" Testing
FORMAT Water Status $+1
EXEC /usr/local/nagios/libexec/submit_check_result localhost "Water Alert level 1" 0 "Water status is ok"
MATCH $+1:(31440.2.2.1.1.4:1)
SDESC
ow-server alert
EDESC

Maybe there are some other Alternatives to determine all Varaibles and their Values .... but i only found this solution
