Custom SNMP Trap Definition

i am not familiar with regex. this is mine.

[root@ve1023:Active] config  cat user_alert.conf
alert CERT_EXPIRE "Certificate (.*?w.*?) in file (.*?w.*?) will expire on (.*?)" {
        snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.300"
}

[root@ve1023:Active] config  logger -p local0.warning "Certificate 'mywork.com' in file mywork.com.crt will expire on Fri Nov 11 23:59:59 2011 GMT"

[root@ve1023:Active] config  tcpdump -nni 0.0 -s0 udp port 162
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

Next, how do I name the trap like the pre-defined traps are. The trap is coming through to my NMS as something generic like "bigIpNotifications.300"

The log message is contained in bigipNotifyObjMsg, but is there a way that I can separate the variable fields (such as the certificate file name, date, etc) into separate fields like bigipSSLCertName, etc so I can parse them on my NMS? All of the pre-defined traps seem to be parsed separately like this.i guess we have to modify f5 mib file; anyway, i have never done it before and not sure if it is supported. hope someone here knows. i am interested too. 🙂
