SNMP Traps on specific server

Hi all,

I would like to send custom snmp trap on a specific snmp server.

I found the article from Deb Allen : https://devcentral.f5.com/articles/custom-snmp-traps

Is possible to implement something like this in alert.conf

    alert BIGIP_MCPD_MCPDERR_POOL_MEMBER_MON_STATUS {
        snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.10"
}

and specify a specific snmp server for this event ?

I hope that i'm clear enough

Thank you

Regards

    i understand trap is enabled by default (because it is in /etc/alertd/alert.conf). trap destination is configured under snmp menu in gui or sys snmp traps in tmsh.

     configuration

root@(ve11a)(cfg-sync In Sync)(Active)(/Common)(tmos) list sys snmp traps
sys snmp {
    traps {
        i192_168_207_28_1 {
            community public
            host 192.168.207.28
        }
    }
}

 trace

    Hello Nitass,

     

    Thank you for your answer, actually in my case i do not want to use the snmp server by configured by default but send specific trap to a specific server

      what about executing snmptrap command using alertd or icall? sol14397: Executing a command or custom script based on a syslog message https://support.f5.com/kb/en-us/solutions/public/14000/300/sol14397.html
