Recently I discovered a great little app called PushOver. This app allows me to receive push notifications on my iOS devices or Mac (it also works for Windows and Android platforms as well, but really who wants to use those) from any service that utilizes the PushOver API such IFTTT. As it turns out, you can very easily integrate PushOver into Nagios as well utilizing a script called notify_by_pushover.sh created by Jedda Wignall (@jedda) . And that is what we did.

It starts with getting the PushOver app installed on your device. It's a few bucks, but seriously, the coolness of getting this to work is worth it.

Next, you'll need to grab Jedda's script from GitHub and put it somewhere on your Nagios server.

You'll then need to configure Nagios to utilize this script for notifcations. So in the commands.cfg, where you have notify-host-by-email and notify-service-by-email commands, also add PushOver commands. They should probably look similar to:

# 'notify-host-pushover' command definition
define command{
        command_name    notify-host-pushover
        command_line    /usr/lib64/nagios/plugins/notify_by_pushover.sh -u $CONTACTADDRESS1$ -a $CONTACTADDRESS2$ -c 'persistent' -w 'siren' -t "Nagios" -m "$NOTIFICATIONTYPE$ Host $HOSTNAME$ $HOSTSTATE$"
        }

# 'notify-service-pushover' command definition
define command{
        command_name   notify-service-pushover
        command_line   /usr/lib64/nagios/plugins/notify_by_pushover.sh -u $CONTACTADDRESS1$ -a $CONTACTADDRESS2$ -c 'persistent' -w 'siren' -t "Nagios" -m "$HOSTNAME$ $SERVICEDESC$ : $SERVICESTATE$ Additional info: $SERVICEOUTPUT$"
        }

Since we still wanted to receive Nagios alert emails in addition to PushOver alerts, it was necessary to define a new PushOver Contact Template:

define contact{
        name                            generic-pushover
        host_notifications_enabled      1
        service_notifications_enabled   1
        host_notification_period        24x7
        service_notification_period     24x7
        host_notification_options       d,u
        service_notification_options    c,u
        host_notification_commands      notify-host-pushover
        service_notification_commands   notify-service-pushover
        can_submit_commands             1
        retain_status_information       1
        retain_nonstatus_information    1
        register                        0
        }

This enabled us to create new contacts to send the PushOver notifications to.

define contact{
        use                    generic-pushover
        contact_name           alek_pushover
        alias                  Alek Pushover
        contactgroups          smartalek_ops
        address1               pushover_user_key_goes_here
        address2               pushover_application_api_key
}

Thats it. Just restart Nagios and you should be good to go.
