How to get ptime from below string

[Veeruswathi]

Hi ,

Below is my field "rtpmap:8 PCMA/8000,rtpmap:101 telephone-event/8000,ptime:20" I would like to get ptime from this , which is 20 . But sometimes i have the field coming as maxptime instead of ptime

Please help

Thanks,
Swathi

Why not just use extract?

| makeresults 
| eval _raw="rtpmap:8 PCMA/8000,rtpmap:101 telephone-event/8000,maxptime:20,ptime:20" 
| extract pairdelim=",", kvdelim=":" mv_add=t

This is the below error : 'ptime:(?\w+)': Regex: unrecognized character after (? or (?-

Hi

Give a try

| makeresults 
| eval msg="rtpmap:8 PCMA/8000,rtpmap:101 telephone-event/8000,maxptime:20" 
| makemv delim="," msg 
| rex field=msg "(ptime:|maxptime:)(?P<ptime>\d+)"

| makeresults | eval test="rtpmap:8 PCMA/8000,rtpmap:101 telephone-event/8000,ptime:20" | rex field=test "ptime:(?\w+)"
