extract two string log file

[lib95]

Hello,

I search to extract the lines containing two string <Begin_DateTime> and <End_Datetime> and RC 0 or 1 from a logfile.
How is it possible to do it ?

Thank you

Best regards

That's 4 things you want to find from the log, based on my counting....

But making all of them match .. https://regex101.com/r/jQvDQ1/1

Hello,

Ok thank you but doesn't resolve my issue
I have created two items logs for get Start and End data, but items are empty
log[/logmsg,,"*Start : [(a-zA-Z0-9+)]"]
log[/logmsg,,"*End [RC*] : [(a-zA-Z0-9+)]"]

So fix it... that's about all I can say based on the info that you provided...

None of your regexes match anything in your initial examples... Those might be bogus, but you should provide some real examples to expect any help. Show us the item config, provide some examples etc.. We are no miracle workers...

Hello,

Thank you, my question was not clear, sorry, on the log file, I try to get the last entries like below :
2023-03-03 02:10:13 Log : ############### END [RC= 0] : 2023-03-02 19:02:59 ################################
2023-03-03 02:10:13 Log : ############### START : 2023-03-03 02:10:13 ########################################

First regex "*Start : [(a-zA-Z0-9+)]"...
1. you cannot start regex with a multiplier... because it has no preceding tokens...
2. your pattern is START not Start...
your regex might be simply ".* START : .*"

Second regex: "*End [RC*] : [(a-zA-Z0-9+)]"...
1. again .. do not start with quantifier...
2. again ... END vs End....
3. [] in regex has special meaning... so if you want to search for [] literally, you need to escape them ..
your regex might be ".*END \[RC=.*\] : .*"
