Hi guys,

i just explained it to Victor in private mail, but this seems to be a FAQ.

                                              ^^
                                              ^^
.._lines=0 means that _no_ lines were scanned for patterns at all.
Why? First, because check_logfiles only examines lines which were appended
to the logfile since the last run. And second, if you run check_logfiles for
the very first time, it does not start searching from the beginning of the
file. It only initializes itself by positioning at the end-of-file.
This was necessary to avoid alerts caused by very old error messages in the
logfile.

This message already exists:
$ check_logfiles --logfile=/var/log/schmarrn.log --criticalpattern=kaas
UNKNOWN - (1 unknown in check_logfiles.protocol-2008-04-17-19-32-10) - could
not find logfile /var/log/schmarrn.log |default_lines=0 default_warnings=0
default_criticals=0 default_unknowns=1

(There is the option "nologfilenocry" which can be set in a
configurationfile. With this option, a missing logfile is silently
tolerated).
