A Squirro cluster can be extensively configured. This section covers the available configuration options and facilities in detail.
The Configuration Files section below outlines the various ways Squirro and its services can be configured. Squirro in a Box also ships with a Puppet configuration, which automates the management of those configuration files.
Puppet is a configuration management utility. It ensures servers are running with the correct configuration. |
Squirro's Puppet recipe is driven by one file: /etc/squirro.yaml. The available configuration settings are described on the separate page squirro.yaml.
Whenever the squirro.yaml file is modified, Puppet should be executed to apply the new configuration. Puppet is executed by running the following command as root:
[root@localhost ~]# puppetrun |
Puppet is run every 60 minutes and upon reboot. When changing a Squirro config file directly, it might be under puppet control and thus any changes are reverted again with the next Puppet run. If you choose not to use Puppet, puppet can be disabled with the following command: |
Each service has its own configuration file /etc/squirro/<servicename>.ini. Additionally there is a common configuration file which applies to all services at /etc/squirro/common.ini.
