Help with regex to extract time in milliseconds

[aniketb]

Hi,

Can someone help me extract the time in MS from the following log line?

Dec 15, 2015 9:35:08 PM org.apache.catalina.startup.Catalina start
INFO: Server startup in 183678 ms

I'm trying this, but doesn't seem to work correctly:

If the message is regular (ie if it always says INFO: Server start up in...) then you would be better off making the regex more explicit.

INFO:\sServer\sstartup\sin\s(?<ms>\d+)\s

You can see the difference between them in the regex debugger on https://regex101.com/

On a side note, you can use the following site to test your regex: https://regex101.com/

Hello

try this regex:

\s*(?<ms>\d*)\s*ms
