How to Integrate

In the following we describe the setup and configuration of the Enterprise Alert Plugin for Nagios. You can find our official listing on the Nagios exchange

  1. In Enterprise Alert (System -> Event Sources -> New Source -> REST API Client) you can create a new REST API end point.
  2. Download the Nagios Plugin from our official listing at exchange Nagios
  3. Copy the two scripts (“” and “”) to your Nagios plugin directory (the location may vary).
  4. Edit the Enterprise Alert REST API URLs in these scripts to the match your REST API URL including your API Key.
  5. Define the new notification commands in the Nagios configuration (a sample configuration is available in the file “ea_commands.cfg”). Please, modify the paths accordingly.
  6. Set up a new contact in Nagios or use an existing one to add notification commands for host and service. You can find an example below:
    define contact{
    contact_name root
    alias Root
    service_notifications_enabled 1
    host_notifications_enabled 1
    service_notification_period 24×7
    host_notification_period 24×7
    service_notification_options w,u,c,r
    host_notification_options d,r
    service_notification_commands ea-service,notify-service-by-email
    host_notification_commands ea-host,notify-host-by-email
    email root@localhost
  7. The alert notification is sent as an event to Enterprise Alert and can be found under Incoming Events.
  8. Based on this event you can start to build an alert policy.

  9. Now you can test it by simulating an alert in Nagios. When Nagios detects an issue, the information is forwarded as an event to Enterprise Alert where your alert policy can then trigger the notification process.
