How to use VM monitoring, metrics, alarms and alerts

Note that the monitoring configuration files are stored under the /etc/abiquo/watchtower path.

The Abiquo UI displays the VM monitoring information, and enables you to manage alarms and alerts. See the following pages:

...

1. In Abiquo, the tenant administrator or user configures the collectd application (authentication and permissions) using OAuth.
   The user must have the “Allow Allow user to push own metrics” metrics privilege and assign this privilege to the application.

2. Users install collectd on their VMs, and then install the Abiquo collectd plugin (from source or using the Abiquo Chef cookbook).

3. The user configures their metrics in collectd.

4. The Abiquo collectd plugin automatically pushes all collectd metrics to the Abiquo API in PUTVAL JSON format.
