Aktivieren von External Commands
Nagios 3 is not configured to look for external commands in the
default configuration as a security feature. To enable external
commands, you need to allow the web server write access to the
nagios command pipe. the simplest way of doing this is to
set check_external_commands=1 in your nagios configuration,
and then change the permissions in a way which will be maintained
across package upgrades (otherwise dpkg will overwrite your
permission changes). The following is the recommended approach:
- activate external command checks in the nagios configuration. this
can be done by setting check_external_commands=1 in the file
/etc/nagios3/nagios.cfg.
sed -i "s/check_external_commands=0/check_external_commands=1/" /etc/nagios3/nagios.cfg
- perform the following commands to change directory permissions and
to make the changes permanent:
/etc/init.d/nagios3 stop
dpkg-statoverride --update --add nagios www-data 2710 /var/lib/nagios3/rw
dpkg-statoverride --update --add nagios nagios 751 /var/lib/nagios3
/etc/init.d/nagios3 start
This is done by intention and will not fixed. See also #538828 for more informations.
Mails Benachichtigungen Limitieren
If you want to receive only 1 mail, it's easy. Set the
notification_interval to 0. But if you want 2, I guess you might achieve
this using escalation and setting notification_interval to 0.
Defining escalation with first_notification 2, and last_notification 2,
it should work.
I must admit I haven't tried it though.
