The alarm expression “ avg(cpu.user_perc) > 5 times 2” requires that the threshold value be exceeded for at least two minutes before the alarm goes to the ALARM state. The default period is 60 seconds and the “times 2” means two 60 second periods. How long does it take for it to change? It should be between two and three minutes given that expression.

I also created an alarm: avg(cpu.user_perc) > 5 times 2 I run the below command to create a cpu load stress --cpu 2 --timeout 600 I can see the alarms are created but there is a latency. Takes some minutes to see the alarm. How can i make it more real time or am i missing something? I checked the times of the two machines and they are same at tha docker side and at my vm.

You can certainly install with just pip install the Ansible role actually does this but in addition runs monasca-setup for you. Using pip is discussed on this page, https://github.com/stackforge/monasca-agent/blob/master/docs/Agent.md#installing The Ansible role can make things even easier in particular if you have Ansible installed. The playbook you call this from can be quite simple, here is one I use: - name: Installs the Monasca Agent hosts: monasca sudo: yes vars: monasca_agent_check_frequency:15 roles: - {role: monasca-agent, tags:[agent]} The key thing to be aware of is that the requirements for the role which are all listed in the README.md at https://github.com/hpcloud-mon/ansible-monasca-agent In the above example those requirements are defined in the group_vars. -- Tim Kuhlman Monitoring HPCloud From: Monasca <[email protected]<mailto:[email protected]>> on behalf of Oğuz Yarımtepe <[email protected]<mailto:[email protected]>> Date: Thursday, August 20, 2015 at 8:07 AM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: [Monasca] question about monasca-agent installation What is the right way to install monasca-agent?
