People, Sorry to bring this subject up again, but i still cannot solve it... Problem: check_log does not send notifications Description: i'm checking a local a file (/var/log/auth.log), i have chmoded it to be readable by others. i have set old file to be same to a place where nagios has write permissions. The web interface shows the correct info (it shows ok state when nothing happens, and it shows critical state when my pattern is found). I have used complex patterns at first, and then change to simple patterns, like "BAD" (without the quotes), and still not working. Something that i noticed is that /var/log/maillog is not even touched when this service reaches critical state. Marc has already tried to help, changing the printf command to echo, but it doesn't solved the problem...
