Analyse logfiles

Is there any tool to search the IPFire Logfile database - esp. to exclude text patterns ?

Here is a command line example that excludes two simple patterns:

grep -v -e "DROP_" -e "INFO" /var/log/messages
[root@ipfire ~]# grep --help

Usage: grep [OPTION]... PATTERN [FILE]...
Search for PATTERN in each FILE or standard input.
PATTERN is, by default, a basic regular expression (BRE).
Example: grep -i 'hello world' menu.h main.c

Regexp selection and interpretation:
. . .
  -v, --invert-match        select non-matching lines
  -e, --regexp=PATTERN      use PATTERN for matching
. . .
