Hi,
I'm trying to skip field if any of below field is missing I couldn't to parse
VD=73,IP=10.4.1.1,M1=1586,M2=158,TB=Mobile,
Grok expression for above
VD=%{NUMBER:VD},IP=%{IPV4:ipaddress},M1=%{NUMBER:m1},M2=%{NUMBER:m2},TB=%{DATA:tt},
Lets Say If VD is missing It has to parse by skipping field, I looking for universal pattern that parses even if any field is missing .
Any idea would be helpful thank you
