Icinga Integration

Icinga is an open source IT infrastructure monitoring tool that offers monitoring and alerting for systems, network devices, applications, and services. Icinga is highly configurable, easily extensible, hence very pervasive.

Opsgenie's Icinga plugin supports a bi-directional integration with Icinga. The integration leverages Opsgenie's Icinga-specific executable and OEC utility to automatically create rich alerts (status, alert histogram, trends, etc.) and synchronizes alert status between Icinga and Opsgenie.

Opsgenie Icinga Plugin Integration

Opsgenie Icinga integration plugin utilizes full capabilities of Opsgenie and provides bi-directional integration with Icinga. Integration leverages Opsgenie's Icinga-specific executable and OEC utility to automatically create rich alerts (status, alert histogram, trends, etc.) and synchronizes alert status between Icinga and Opsgenie.

Installation

The steps below describe how to integrate Opsgenie and Icinga using Opsgenie Icinga integration plugin. Note that slight alterations may be needed for these instructions depending on your exact Linux distribution and your Icinga configuration.

🚧

If you're using Lamp based Icinga plugin, backup all existing configurations. Uninstall the old plugin, then install the new one.

Prerequisites

Packages provided support the following systems:

  • Red Hat based linux distributions
  • Debian based linux distributions

Download Opsgenie Icinga Plugin

For Red Hat Based Distributions

rpm -i opsgenie-icinga-<your_version>.rpm

πŸ“˜

For rhel6 distributions, you can download this package.

🚧

During upgrades, rpm package does not overwrite your existing configurations. It saves the new default configuration file as opsgenie-integration.conf.rpmnew. Find more information about rpm upgrades config file handling from here.

🚧

If you want to update from version 201X-XX-XX to 2.X.X, you must add --force parameter. E.g.:
rpm -U --force opsgenie-integration-<your_version>.rpm

We suggest that you backup existing configuration files before update!

For Debian Based Distributions

dpkg -i opsgenie-icinga-<your_version>.deb

Add Icinga integration to Opsgenie

  1. Please create an Opsgenie account if you haven't done so already.
  2. Go to Opsgenie's Icinga Integration page.

🚧

For Free and Essentials plans, you can only add the integrations from the Team Dashboards, please use the alternative instructions given below to add this integration.

There are three ways to configure golang-executable file:

  1. Configuring from conf file: Configure from /home/opsgenie/oec/conf/opsgenie-integration.conf file. Configuring from conf file will overwrite the configurations made in the script.
  2. Configuring by using Golang Flags: Configure by entering flags to command in the opsgenie.cfg file. Use -apiKey flag for your apiKey and -is flag for your icinga_server name. If multiple Icinga servers aren't being used, the Icinga server does not need to be defined. Using flags overwrites all the other configuration methods mentioned above.

πŸ“˜

To send additional custom arguments, add them after the flags as: customArgName1 customArgValue1 customArgName2 customArgValue2
Parse custom arguments by adding {{_payload.customArgName}} to wherever is needed in the input fields.
For more information about using raw parameters please visit Dynamic Fields document.

  1. Configuring from script: Configure apiKey and icinga_server from send2opsgenie.go script. If this option is used, build the script again and put the new executable to /home/opsgenie/oec/opsgenie-icinga directory. Find information about the location of the send2opsgenie.go and how to build a go script in the Source section.

πŸ“˜

Configure the golang-executable to use a proxy for sending HTTP requests by defining the environment variable HTTP_PROXY=http://host:port

Define Icinga contacts

  1. Copy /home/opsgenie/oec/opsgenie-icinga/opsgenie.cfg config file, (configures a contact and its host and service notification commands) to /usr/local/icinga/etc/objects directory.
cp /home/opsgenie/oec/opsgenie-icinga/opsgenie.cfg /usr/local/icinga/etc/objects
  1. Add the following line to the main Icinga configuration file (ICINGA_HOME/etc/icinga.cfg)
...
cfg_file=/usr/local/icinga/etc/objects/opsgenie.cfg
...
  1. Add the contact "opsgenie" to the Icinga configuration’s main contact group in ICINGA_HOME/etc/objects/contacts.cfg file. If using the default configuration, contacts.cfg, add "opsgenie" user to the "admins" contact group.
  2. Restart Icinga.

If everything goes well, alerts are seen in Opsgenie for every notification created in Icinga.

Configure Opsgenie to Icinga Integration (Optional)

πŸ“˜

In order to use this feature "Send Alert Actions To Icinga" and "Send via OEC" checkboxes should be enabled in Opsgenie Icinga Integration.

Use Opsgenie's OEC and the Icinga script to update alerts on Icinga. This enables deployment of your own scripts/ability to modify the ones provided and execute customized actions on Icinga.

To be able to execute actions in Icinga, OEC gets the configuration parameters from the configuration file. The configuration file can be found under /home/opsgenie/oec/conf/config.json

Configuration Parameter

Description

alert_histogram_image_url

OEC retrieves histogram images from Icinga using this URL. Localhost should be replaced with the Icinga server address.

trends_image_url

OEC retrieves trends images from Icinga using this URL. Localhost should be replaced with the Icinga server address.

command_url

URL to update Icinga alerts when alerts get acknowledged, commented, etc.

user

Username to authenticate Icinga web server to get Icinga histogram and trends images.

password

Password to authenticate Icinga web server to get Icinga histogram and trends images.

The package that you downloaded also includes OEC utility which is located under /usr/local/bin and the script that is needed to be run by OEC which is under /home/opsgenie/oec/scripts. After the configuration of OEC is done, you need to run it. In order to learn more about how to run OEC, you can refer to the Running OEC documentation.

🚧

Icinga integration package does not support SSL v1.0. If your Icinga Server has SSL v1.0, we suggest you to upgrade your SSL server.

FAQ and Troubleshooting

If the integration is not working, please check if the problem is mentioned below, and follow our advice:

1. Icinga alerts are not getting created in Opsgenie:

Run the following test command from the shell. Check if the test alert is created in Opsgenie:

/home/opsgenie/oec/opsgenie-icinga/send2opsgenie -entityType=host -t=PROBLEM -hs=DOWN -hn=test_host
  • If a "Trace/breakpoint trap" error occurs: It means the send2opsgenie plugin being used isn't compatible with your server distribution. Follow the "Source and Recompiling send2opsgenie" section below and rebuild your send2opsgenie.go according to your specific server environment.
  • If the alert is created in Opsgenie: It means the integration is installed correctly. The problem might be that Icinga is not notifying the Opsgenie contact for alerts. Check the Icinga alert notifications log.
  • If not: Check the logs at /var/log/opsgenie/send2opsgenie.log. Look for the following errors in the log file:
  • If the error "RestException[Could not authenticate.]" is in the logs, it means Opsgenie couldn't identify the API key. Check if the API key is set correctly, as explained in "Opsgenie Plugin Configuration in Icinga" above.
  • If the error "Could not execute this action with apiKey of [Icinga] integration" is in the logs, make sure that the correct Icinga integration package was doanloaded and used, not Icinga 2 or any other.
  • If unsure of the problem, set the plugin's log level to debug, try again and send the logs to us with out contact us form, so we can problem solve on our end and attempt to find a solution for you.
  • If there is no /var/log/opsgenie/send2opsgenie.log file, or there are no logs in it, check the following:
  • First, make sure the icinga user haspermission to write to /var/log/opsgenie directory. The installation package automatically does this for you. If an error occurs, execute: chown -R icinga:opsgenie /var/log/opsgenie
  • Check the Icinga server logs at /usr/local/icinga/var/icinga.log. See if there are error logs regarding send2opsgenie, and contact us with them.

Setting send2opsgenie plugin's log level to DEBUG:

Change the line send2opsgenie.logger=warning to icinga2opsgenie.logger=debug in /etc/opsgenie/conf/opsgenie-integration.conf file.

2. The Icinga alert is not acknowledged when the alert is acked in Opsgenie:

  • First, check the alert logs.
  • If the "Posted [Acknowledge] action to Icinga.." action is not in the log, it means Opsgenie didn't send the Acknowledge action to Icinga. Check the integration configuration, as it might not have matched the alert action.
  • If the "Posted [Acknowledge] action to Icinga.." action is not in the log and no related log after that, it might mean OEC is having connection problems. Check the logs.

3. Could not open Icinga RPM package

If while installing the rpm package you get an error saying that the package is obsolated, you need to use "rpm -i opsgenie-icinga-1.0.4-rpm-x86-64.rpm --nodeps" instead.

If you get "is already installed" error, use "rpm -i opsgenie-icinga-1.0.4-rpm-x86-64.rpm --force" instead.

Source and Recompiling send2opsgenie

The source for the executable send2opsgenie is located under /usr/bin/ and send2opsgenie.go is located under /etc/opsgenie/ and is also available at GitHub Opsgenie Integration repository. To change the behavior of the executable, edit send2opsgenie.go and build it using:

go build send2opsgenie.go

For installing go, refer to https://golang.org/doc/install. Note that the executable in the plugin is built for linux/386 systems.
