Nagios4 configuration check on start \ reload

Recently installed a new Build 4.0.3 - I am familiar with Nagios also have a 3.0b5 build running..
On my 3.0b5 build when ever the Nagios service is started / restarted / reloaded a configuration check is run and the output is seen as below.
Code: Select all
[root@nagios ~]# service nagios reload
Running configuration check...done.
Reloading nagios configuration...done
On the new build (for me) this is not happening. And the output is a bit different.
Code: Select all
[root@nagiosvm ~]# service nagios reload
nagios (pid 10681 10680 10679 10678 10677 10675) is running...
Reloading nagios: [ OK ]
Is this a feature change in the newer versions..
Let me know..
Thank you
Jon

What distro is this installed on, and was it installed by a package manager, or source?

Does your /etc/init.d/nagios have checkconfig="true"? If so it does do a config verification, however any output is redirected to a file for logging (/tmp/.configtest.XXXXXXXX)

This is how my /etc/init.d/nagios file is set..
Code: Select all
reload() {
echo -n $"Reloading $prog: "
killproc -p ${pidfile} $exec -HUP
RETVAL=$?
echo
}
I am not sure if the previous Admin set it up this way or not but on the old Nagios 3.05b box the reload looks like this.
Code: Select all
reload|force-reload)
printf "Running configuration check..."
$NagiosBin -v $NagiosCfgFile > /dev/null 2>&1;
if [ $? -eq 0 ]; then
echo "done."
if test ! -f $NagiosRunFile; then
$0 start
else
pid_nagios
if status_nagios > /dev/null; then
printf "Reloading nagios configuration..."
killproc_nagios nagios -HUP
echo "done"
else
$0 stop
$0 start
fi
fi
else
echo " CONFIG ERROR! Reload aborted. Check your Nagios configuration."
exit 1
fi
;;
*)
echo "Usage: nagios {start|stop|restart|reload|force-reload|status|check}"
exit 1
;;
esac
# End of this script
On the 3.05b version - when a reload command was executed, the config files were checked for errors and if there were any problems it would not reload .
Looks like I would need to change the current version reload settings to match that of the old reload settings to accomplish this?
Let me know if this is correct.
Thank you
Jon

I would tend to agree, the 3.05 one looks correct. As a side note, the init scripts are a part of several bug fixes that are being worked on or have already been completed for core.

I upgraded to 4.0.4 last week and noticed right away that the configuration check that I was used to seeing in 3.0b5 upon a nagios service reload was working again in the new version.
Code: Select all
[root@nagiosvm ~]# service nagios reload
Running configuration check...Reloading nagios configuration...done
Thank you
