=== Spellcheck === | |||
Checks that the spelling checker service is available. Requires [[Nagios#NRPE|NRPE]] to installed and running 1st. | |||
On the Zimbra server, add the following to <code>/etc/nagios/nrpe.cfg</code> | |||
command[check_zimbra_spell]=/usr/lib/nagios/plugins/check_http -H localhost -p 7780 | |||
Add a new service (on Nagios server)... | |||
define service { | |||
use zimbra-svc-template | |||
hostgroup_name zimbra-servers | |||
service_description Zimbra Spelling | |||
check_command check_nrpe!check_spell | |||
} | |||
== Dependency Checks == | |||
=== DNS === | |||
Checks that your Zimbra server is able to make DNS lookups. Requires [[Nagios#NRPE|NRPE]] to installed and running 1st. | |||
Note that if you need to consider which DNS server(s) it is most appropriate to check against. For example, if you run a local Bind instance on your Zimbra server, you may want to test both that, and the DNS server which it forwards requests to. | |||
On the Zimbra server, add the following to <code>/etc/nagios/nrpe.cfg</code> | |||
command[check_dns]=/usr/lib/nagios/plugins/check_dns -H google.com | |||
If you need to resolution again a DNS server different to the default (as specified in <code>/etc/resolv.conf</code> use the <code>-s</code> option, for example... | |||
command[check_dns]=/usr/lib/nagios/plugins/check_dns -H google.com -s 8.8.8.8 | |||
Add a new service (on Nagios server)... | |||
define service { | |||
use zimbra-svc-template | |||
hostgroup_name zimbra-servers | |||
service_description DNS Resolution | |||
check_command check_nrpe!check_dns | |||
