How to capture Multiple values in single group via regex?

[abhishekbhasin]

Need to extract P302 P1 P2 with a single regular ex I build (?<Par>P[1-9][0-9]*) but when I run this in splunk it only captures first (P302)

 [SearchBroker - XXX] - [submitSearch] INFO: XXX [] - submitSearch time=36 pTime={P302=11,P1=7,P301=13,P2=24,P3=23,P4=31,P5=25,P6=23,P300=13,P7=23,P8=24,P9=24,P10=21,P12=24,P11=23,P1000=1,P14=26,P13=24,P16=21,P15=20,P18=20,P17=23} pProcessTime={P302p=10,P1p=6,P301p=12,P2p=23,P3p=22,P4p=30,P5p=24,P6p=23,P300p=13,P7p=23,P8p=24,P9p=24,P10p=21,P12p=23,P11p=22,P1000p=0,P14p=26,P13p=23,P16p=20,P15p=20,P18p=20,P17p=23} pWaitTime=

Full syntax please rex max_match=3 ...  (?<Par>P[1-9][0-9]*) doesn't work

The ellipsis (...) were to indicate the rest of your command - try it like this

| rex max_match=3 "(?<Par>P[1-9][0-9]*)"

Thanks!. It works

Can you explain "doesn't work?"  This is a test:

| eval _raw = " [SearchBroker - XXX] - [submitSearch] INFO: XXX [] - submitSearch time=36 pTime={P302=11,P1=7,P301=13,P2=24,P3=23,P4=31,P5=25,P6=23,P300=13,P7=23,P8=24,P9=24,P10=21,P12=24,P11=23,P1000=1,P14=26,P13=24,P16=21,P15=20,P18=20,P17=23} pProcessTime={P302p=10,P1p=6,P301p=12,P2p=23,P3p=22,P4p=30,P5p=24,P6p=23,P300p=13,P7p=23,P8p=24,P9p=24,P10p=21,P12p=23,P11p=22,P1000p=0,P14p=26,P13p=23,P16p=20,P15p=20,P18p=20,P17p=23} pWaitTime="
| rex max_match=3 "(?<Par>P[1-9][0-9]*)"

Output is exactly 3 values in Par.

Maybe you need all of them?  Then max_match=0.
