How to strip characters in SNMP value

[sharafy]

Zabbix Version: 3.0.9

Hi,

I'm trying to monitor a system using SNMP. I added the OID, however when I get the data it contain a text and then the value. For example:

# snmpwalk -v 2c -c public 192.168.1.5 netSnmpExtendMIB.4.1.2.4.105.110.102.111.11
NET-SNMP-EXTEND-MIB::netSnmpExtendMIB.4.1.2.4.105.110.102.111.11 = STRING: "session-total: 0"

In zabbix, the value that I'm getting for the above item is "session-total: 0". Also, I will be setting up trigger and alert for this item. How can I discard the "session-total:" and simply keep 0 for this item? I came across few posts that mentioned the use of Regex and Macros but I'm not sure what is the best way to do this.

Can someone please help me with this?

Thanks.

Hello sharafy!

This functionality will only be released soon: https://www.zabbix.com/documentation..._preprocessing
What you are left with currently, I believe, is to implement externalscript or UserParameter for this kind of item and trim the returned value using third-party tools like sed and awk.

Functions are used for trigger operations mainly, while macros are the values to be substituted from host to host, not entirely your case.

Hi Ovas,

Thanks.

I came across the preprocessing feature. I will wait until that is released.In the meantime, I will look into the external script.

Thanks again.
