the channel token look like this: ctITmPr7aZkaTmPr7aZkaTmPr7aZkaTmPr7aZkaTmPr7aZka
Step 3: Nagios configuration
Create the command definitions in your Nagios configuration:
define command { command_name notify-host-by-dadapush command_line /usr/local/nagios/libexec/nagios-dadapush.sh -a "$NOTIFICATIONTYPE$" -b "$HOSTNAME$" -c "$HOSTSTATE$" -d "$HOSTOUTPUT$" -T "DADAPUSH_CHANNEL_TOKEN" } define command { command_name notify-service-by-dadapush command_line /usr/local/nagios/libexec/nagios-dadapush.sh -a "$NOTIFICATIONTYPE$" -b "$HOSTNAME$" -e "$SERVICEDESC$" -f "$SERVICESTATE$" -g "$SERVICEOUTPUT$" -T "DADAPUSH_CHANNEL_TOKEN" }
replace “DADAPUSH_CHANNEL_TOKEN” with your channel token.
Create the contact definition in your Nagios configuration:
define contact { contact_name dadapush alias dadapush service_notification_period 24x7 host_notification_period 24x7 service_notification_options w,u,c,r host_notification_options d,r host_notification_commands notify-host-by-dadapush service_notification_commands notify-service-by-dadapush }
The service_notification_options directive is used to define the service states for which notifications can be sent out to this contact. Valid options are a combination of one or more of the following:
w: Notify on WARNING service states
u: Notify on UNKNOWN service states
c: Notify on CRITICAL service states
r: Notify on service RECOVERY (OK states)
f: Notify when the service starts and stops FLAPPING
n (none): Do not notify the contact on any type of service notifications
The host_notification_options directive is used to define the host states for which notifications can be sent out to this contact. Valid options are a combination of one or more of the following:
d: Notify on DOWN host states
u: Notify on UNREACHABLE host states
r: Notify on host RECOVERY (UP states)
f: Notify when the host starts and stops FLAPPING
s: Send notifications when host or service scheduled downtime starts and ends
n (none): Do not notify the contact on any type of host notifications.
Add the contact to a contact group in your Nagios configuration:
define contactgroup{ contactgroup_name network-admins alias Network Administrators members email, dadapush }
Now the configuration is finished. Before applying the new configuration, run the following command to check for any error or mistake:
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
If there are no errors, restart the nagios service:
Step 4: test Nagios notifications
Now that we have everything configured how can we be sure that our notifications are working? use the check_dummy plugin (from the Nagios Plugins pack) and set it up to return a CRITICAL status, for example:
Other status codes you can return are:
0 - OK 1 - Warning 2 - Critical 3 - Unknown
