Expose the carbon port (2003) when installing Carbon/Graphite and docs
* Expose carbon_cache_port to the config file and via the firewall * Small cleanup job around the Graphite/Grafana playbook for consistency * Docs for building a monitor host Change-Id: I9e15eac3ce749c341ebf464f165f73c0a87212e5

Installation
|
||||
~~~~~~~~~~~~
|
||||
|
||||
1. Deploy machine (RHEL7 is used in this example)
|
||||
2. Install RPMS
|
||||
|
||||
::
|
||||
|
||||
[root@dhcp23-93 ~]# yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
|
||||
...
|
||||
[root@dhcp23-93 ~]# yum install -y ansible git
|
||||
|
||||
3. Clone Browbeat
|
||||
|
||||
::
|
||||
|
||||
[root@dhcp23-93 ~]# git clone https://github.com/openstack/browbeat.git
|
||||
Cloning into 'browbeat'...
|
||||
remote: Counting objects: 7533, done.
|
||||
remote: Compressing objects: 100% (38/38), done.
|
||||
remote: Total 7533 (delta 30), reused 36 (delta 23), pack-reused 7469
|
||||
Receiving objects: 100% (7533/7533), 5.26 MiB | 5.79 MiB/s, done.
|
||||
Resolving deltas: 100% (4330/4330), done.
|
||||
|
||||
4. Add a hosts file into ansible directory
|
||||
|
||||
::
|
||||
|
||||
[root@dhcp23-93 ~]# cd browbeat/ansible/
|
||||
[root@dhcp23-93 ansible]# vi hosts
|
||||
|
||||
Content of hosts file should be following
|
||||
|
||||
::
|
||||
|
||||
[graphite]
|
||||
localhost
|
||||
|
||||
[grafana]
|
||||
localhost
|
||||
|
||||
5. Setup SSH config, SSH key and exchange for Ansible
|
||||
|
||||
::
|
||||
|
||||
[root@dhcp23-93 ansible]# touch ssh-config
|
||||
[root@dhcp23-93 ansible]# ssh-keygen
|
||||
Generating public/private rsa key pair.
|
||||
...
|
||||
[root@dhcp23-93 ansible]# ssh-copy-id root@localhost
|
||||
...
|
||||
|
||||
6. Edit install variables
|
||||
|
||||
::
|
||||
|
||||
[root@dhcp23-93 ansible]# vi install/group_vars/all.yml
|
||||
|
||||
Depending on the environment you may need to edit more than just the following
|
||||
variables - graphite_host and grafana_host
|
||||
|
||||
|
||||
7. Install Carbon and Graphite via Ansible playbook
|
||||
|
||||
::
|
||||
|
||||
[root@dhcp23-93 ansible]# ansible-playbook -i hosts install/graphite.yml
|
||||
...
|
||||
|
||||
8. Install Grafana via Ansible playbook
|
||||
|
||||
::
|
||||
|
||||
[root@dhcp23-93 ansible]# ansible-playbook -i hosts install/grafana.yml
|
||||
...
|
||||
|
||||
9. Install Grafana dashboards via Ansible playbook
|
||||
|
||||
::
|
||||
|
||||
[root@dhcp23-93 ansible]# ansible-playbook -i hosts install/grafana-dashboards.yml -e 'cloud_dashboards=false'
|
||||
...
|
||||
|
||||
Now navigate to http://monitoring-host-address:3000 to verify Grafana is
|
||||
installed, the Graphite data source exists and custom dashboards are uploaded.
|
||||
|
||||
You can now point other clouds at this host in order to view System and
|
||||
Application performance metrics. Depending on the number of clouds and
|
||||
machines pointed at your monitoring server, you may need to add more disk IO
|
||||
capacity, disk storage or carbon-cache+carbon-relay processes depending
|
||||
entirely on the number of metrics and your environments capacity. There is a
|
||||
Graphite dashboard included and it is recommended to install collectd on your
|
||||
monitoring host such that you can see if you hit resource issues with your
|
||||
monitoring host.
