escalations

[Brian Andrus]

I am having trouble with the event handler. I have set up a test one for
vsftpd on the same box nagios is running on.
I created a restart-vsftpd script based on the http example to restart the
service (it is below).
I set up the command in the config and added the event_handler option to the
service (excerpts from the config files are below).

The even handler does get fired off three times when I down the service.
>From the log files, it gets called as CRITICAL SOFT 1, CRITICAL SOFT 2,
CRITICAL HARD 3 (at which point the script should actually do something).
The problem is that the script seems to call the /etc/rc.d/init.d/vsftpd
restart, but it exits after failing to shut it down. I get an entry in the
messages.log file "vsftpd: vsftpd shutdown failed" but I don't get the
startup succeeded message which I do get if I run "vsftpd restart" from the
command line.


Has anyone else seen this behaviour? I am running Fedora Core 1.
