Naemon notifications to Zulip

Zulip already has a Nagios integration which is also working for Naemon but every notification is creating it’s own topic and this what I want to avoid. Due to Zulip’s API this can also be achieved without changing the Nagios integration.

• Requirements
• Zulip
• Naemon

Requirements

It’s also possible to send a curl command but I decided to use zulip-send ‘cause of the “cleaner command”.

To get zulip-send it’s necessary to install the Zulip python bindings on the Naemon host:

pip install zulip

Zulip

Now it’s time to create a bot. Let’s call it ‘monitoring-bot@example.com’. You can then download the zuliprc file and put it into the home folder (~/.zuliprc) of the naemon user.

In my case I’m using OMD with Naemon backend and the OMD site is called internal.

OMD[internal@srv-mon-01]:~$ cat ~/.zuliprc
[api]
email=monitoring-bot@example.com
key=1234
site=https://zulip.example.com

Naemon

The service notification command:

# etc/naemon/conf.d/notification_command_zulip.cfg
# multiline messages are a little tricky - carriage return is necessary to output newlines
define command {
    command_name notify-service-by-zulip
    command_line /usr/local/bin/zulip-send --stream <STREAM> --subject <TOPIC> \
        --message "`echo \"**$NOTIFICATIONTYPE$**: $HOSTNAME$\r\n**Service**: $SERVICEDESC$ is $SERVICESTATE$\r\n\n**Description**\r\n$SERVICEOUTPUT$\"`"
}

After changing the service_notification_command at the contact object and a naemon restart this will produce following Zulip message:

Of course the same can be applied host notifications and different OMD sites.

Tested with:

• Naemon 1.0.9
• Zulip 1.9.1
