Tutorial: Connecting Icinga

Meerkat can connect to Icinga2 to create dashboards from Icinga2 objects like Services and Host Groups. Meerkat uses the Icinga2 HTTP API.


  • An Icinga2 Server with the HTTP API set up
  • Network connectivity between Meerkat and Icinga. Meerkat must be able to initiate a connection to the Icinga server. The Icinga API is usually served on TCP port 5665.
  • Permissions to edit the Icinga configuration files. We will be creating a user to access Icinga’s API.
  • Permissions to edit the Meerkat configuration file. The new user will be added.

1. Create a ApiUser object for Meerkat

Create an ApiUser object with read-only privileges. In a default installation, this configuration may be written to the file /etc/icinga2/conf.d/api-users.conf. We will use the example username and password “meerkat”.

object ApiUser "meerkat" {
	password = "meerkat"
	permissions = [ "objects/query/Host", "objects/query/Service", "objects/query/ServiceGroup", "objects/query/HostGroup", "events/StateChange" , "events/CheckResult", "events/AcknowledgementSet", "events/AcknowledgementCleared", "status/query" ]

Reload the Icinga daemon. On Linux systems using systemd, this can be done with:

systemctl restart icinga2

2. Add the new user to Meerkat

Set the Icinga URL and the username and password we just created in Meerkat’s configuration file:

IcingaURL = "https://icinga.example.com:5665"
IcingaUsername = "meerkat"
IcingaPassword = "meerkat"

If the Icinga instance uses self-signed certificates, set IcingaInsecureTLS:

IcingaInsecureTLS = true

Restart Meerkat to reload its configuration file. On Linux systems using systemd:

systemctl restart meerkat

3. Test creating Icinga dashboard elements

Browse to the URL serving Meerkat.

Choose a dashboard (or create a new one).

Click “add element” then select “Icinga Service” from the dropdown box.

See the demo Meerkat and the screenshots for inspiration on creating dashboards with Icinga elements.

More advanced usage of the Icinga elements, such as rendering check result output, filtered with regular expressions, are yet to be documented!
