REGEX with look ahead not working
Posted: 03 Aug 2023, 15:31
I am trying to ignore entries in my /usr/local/cpanel/logs/error_log, where my hosting company does not allow use of the cPanel Store directly. The hosting company also resells the cPanel add-on products.
My server environment is:
OS: CentOS v7.9.2009 STANDARD virtuozzo
cPanel Version: 110.0.9
The special need is that the error_log entry begins with a date/time, and then there are subsequent lines followed by a newline character that are part of the initial error_log entry; until the next new entry which begins with a date/time. I want to ignore the entire log entry (multiple lines) using csf.logignore.
My REGEX works at regex101.com but DOES NOT work on my server, when added to my csf.logignore.
YES, I have restarted LFD after editing the file.
If I remove the regex look ahead "?=..." csf will ignore the 1st line OK, but will include the subsequent lines in the email logfile report (not what we want).
I have the following working when tested at regex101.com , using flavor PCRE2.
