Hello all,
I am trying to extract fields (tried the dynamic extraction and manual using rex®ex) but am unable to get it just right. My data looks like the following:
Apr 30 00:48:25 "ip_address" Apr 30 2012 00:48:25: %ASA-4-113019: Group = "Group",
Username = "User", IP = "ip_address",
Session disconnected. Session Type: SSL, Duration: 1h:59m:24s, Bytes xmt: 86659734,
Bytes rcv: 4557700, Reason: User Requested
I would like to extract the Bytes xmt and Bytes rcv to separate fields (on search time). Then I would like pipe to an eval statement that adds them then another pipe to the timechart.
I have tried a lot of regex and rex combinations using this site regular expression reference as a ref . But I've only gotten as far as rex field=_raw "Bytes xmt: (?
I am probably doing this entirely wrong as this is my first expression so any help you can give would be great!
Thank you,
How about
rex field=_raw ".*Bytes xmt: (?<bxmt>\d+), Bytes rcv: (?<brcv>\d+),.*"
How about
rex field=_raw ".*Bytes xmt: (?<bxmt>\d+), Bytes rcv: (?<brcv>\d+),.*"
Got it and now have a better understanding of rex®ex. Thank you for all of your help and prompt responses!
Edited to show the backslashes.
There should be backslashes in front of the d+ characters. The comment forum doesn't always post them properly.
Thank you for your prompt response. I've copied and pasted what you've wrote, but the extracted fields bxmt and brcv do not show up under the selected fields nor interesting fields, so seemingly they have not been extracted. Is there something I'm missing or do I just pipe the additional statements (eval and timechart)?
