Seems that I’m not the only one struggling with regex that works on regex101.com and don’t in Graylog (https://community.graylog.org/t/regex-works-on-regex101-com-but-not/13272), but even after trying to escape twice the “\d”, it still doesn’t match!
Please find the input string : [mux_input 632] [encaps] dropping late packet (0 ms)
And the working regex on regex101 : \d+(?:[,.]\d+)?
(I’m trying to get “632”).
This one doesn’t match anything in Graylog, doubling the escape doesn’t match either : \d+(?:[,.]\d+)?
Would you have any idea what’s the issue here?
