\"nagios\"\/<\/a> nagios<\/a> is a great open source service\/server monitor, i’ve been using it for a very long time. one thing i noticed, however, as you update the various config files, if you make a mistake and try to start nagios again it will report this error:<\/p>\n

\n[root@ethereal nagios]# .\/nagios.initscript start
\nStarting network monitor: nagios
\nNo lock file found in \/usr\/local\/nagios\/var\/nagios.lock\n<\/p>\n<\/blockquote>\n

not all that helpful, but if you look in your messages log it is much more helpful:<\/p>\n
