Chapter 7. Monitoring Hosts
The Red Hat Enterprise Linux OpenStack Platform installer user interface provides a number of functions for monitoring the hosts it manages. These functions are accessed via the Monitor menu in the main title bar.
7.1. Dashboard
The Dashboard page is the main screen displayed when you log in to the user interface, and presents an overview of the current status of all hosts that the installer manages. You can access the dashboard at any time from anywhere in the user interface by clicking → .
There are three key elements to the dashboard:
Host Configuration Status
This section contains a table and a pie graph that outline the total number of hosts that the installer manages and the current state of each host. Hosts are categorized according to status, and you can click the title of a status type to display a list of all hosts currently reporting that status.
Latest Events
This section displays a list of any recent events that have been recorded in the installer over the most recent one-week period.
Run distribution in the last 30 minutes
This section contains a time series that displays the number of Puppet runs executed over the most recent report interval. By default, this interval is 30 minutes. The time series is broken into sub-intervals that represent 10% of the overall report interval length, each of which display the number of runs executed during that sub-interval.
