Changing config files while nagios is running causes webinterface to mess up

[Michael Huettig]

Hi Raphael,
you are right:
The WEB-Interface gets confused, if you are changing your config, 'cause of 
the CGI's handnling and display nagios status, but nagios is running 
correctly, so it's on your hand to decide wether you have to restart nagios 
after any small changes or make some changes for a while and then restarting 
nagios, i've written some small scripts, which check nagios-config 
(
#!/bin/sh
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
)
and restart nagios
(
#!/bin/sh
PATH=/usr/local/bin:/usr/bin:/usr/X11R6/bin:/bin:.
# Nagios-cfg checken und Nagios durchstarten
/usr/local/nagios/bin/check_nagioscfg >/dev/null
RETVAL=`echo $?`
#echo $RETVAL
if [ $RETVAL = 0 ]; then
        echo "[`date +%s`] RESTART_PROGRAM;`date +%s`" 
>/usr/local/nagios/var/rw/nagios.cmd
fi

Hope this helps ...

Regards

Michael
