Regular Expression for field extraction

Hi everyone,

i got two URLs which i want to represent in one regex group. The dest Port (443) will be in a seperate group

Here are two examples.



my.url.is.here:443

http://myurl.de/tasks/search/home?

 

When i use the following regex "(?<url>[^\s:]+):?" the first example is fine, but the second only catches "http" because it only matches till the ":"

Can someone help and fix my regex?

Thanks.

Hi @ITWhisperer thx for the reply. Now the first number of the dest port is lost.

It captures everything till "my.url.is.here:4"

I'm not 100% sure what you want to see.

This is my search

index=mysearch
|  rex "\s(?<url>.+)(:\d|\?)(?<dest_port>\d+)?\s+"

If you don't mind losing the ?, you could use

"(?<url>.+)(:\d|\?)"
