Yes you can use those Ansible roles to install to another node. This is what the Monasca Vagrant<https://github.com/stackforge/monasca-vagrant> dev environment does, it creates two VMs one with devstack and the UI and the other with everything else on it. I would suggest using that.

If for some reason you want to install apart from those VMs to another node, the vagrant environment can at least be used as a guide for how to use the Ansible. The mini-mon.yml file is the playbook that installs the Monasca stack. It pulls its variables from the host and group vars, some of which will have to be modified to set the right ips etc.

If i want to install Monasca to my test environment, except from UI part, will i use and install all cookbooks listed here https://github.com/search?utf8=%E2%9C%93&q=ansible-monasca to another node as a monitoring node?

Subject: Re: [Monasca] question about monasca-agent installation

Hi,

I removed the times part and it worked as expected. Is there a possibility to lower the default 60 seconds evaluation period?

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.

Subject: Re: [Monasca] question about monasca-agent installation

I followed the pip method and set the monasca agent manually at one of my vms and used the monasca docker instance  also for keystone url and monasca api url.
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 have some options on how you install the agent. 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.

Subject: [Monasca] question about monasca-agent installation


What is the right way to install monasca-agent? Using https://github.com/hpcloud-mon/ansible-monasca-agent or pip install?

How will the ansible cookbook be used? There is no main.yml to run the cookbook. Anyone can give me an example?
