    Hi i am krishna, i am seeting up a clustering with 2 nodes on RHEL 7.1 OS. I have an application(exe) which shall runs shell script which in-turn runs multiple binary executables which records audio/video files from hardware through ethernet” in active node. When active node fails then i want to send the notification event about active node state to the other node saying to start recording audio/video files.

    My problem is how to send notification about failure of a active node and its state????

    Thank you so much for this post Pradeep! I needed to quickly build a test Icinga server to learn how to use it and this was SO HELPFUL and I got the server built in about 15 minutes. Now I can focus on adding nodes, monitors, etc. Thanks!!

    There is one step missing. After installation of icinga2 it is neccesary to enable command feature of icinga2 in order to receive commands from icinga web. Please add this command to your tutorial:

    “icinga2 feature enable command”

      I get the error – “icinga2: Can’t send external Icinga command to the local command file “/var/run/icinga2/cmd/icinga2.cmd”: Permission denied.” even after enabling the icinga2 (icinga2 feature enable command)

      Any suggestions please??
