Foglight for OpenStack 5.7.4 - User Guide

Action panel

The action panel is at the far right of the Foglight browser interface.

The action panel provides you with easy access to several useful actions and tasks.

Agents view

The Agents view is available on the OpenStack Environment dashboard. To find it, open the OpenStack Environment dashboard and click the Administration tab.

For more information about this dashboard, see Using the OpenStack Environment dashboard .

The Agents view displays information on the various agent systems that are collecting and sending details to Foglight for OpenStack. This view can be used to verify that agents are properly reporting information at regular intervals to Foglight for OpenStack.

Each agent in the Agents view contains an alarm summary that shows you the number of alarms of each severity that are presently outstanding for the agent.

Alarm Analytics tab

This tab is available in the OpenStack Explorer. To find it, open the OpenStack Explorer and on the Topology tab that appears on the navigation panel, select a Host, Instance, or Volume. In the OpenStack Explorer, open the Alarm Analytics tab.

The Alarm Analytics tab displays resource-related metrics collected about a Host, Instance, or Volume over a selected time period, and also shows any events that occurred during that time frame.

This view is made up of the following embedded views:

This view shows a chart with the utilization percentage or all values for one or more metric values selected in the Source Object/Metric view.

This view can give you a good idea on how the current resource consumption affects your environment as a whole. For example, a steady increase in memory consumption can trigger memory utilization alarms, which typically indicate that you need to allocate more memory to the affected Server.

This view allows you to select the metrics that appear in the chart view on the right. Possible metric types include: CPU Metrics, Disk Metrics, Memory Metrics, and Network Metrics. For each metric type, you can display the values of a selected metric, or all metric values associated with that type.

For example, selecting Disk Metrics gives you an option of displaying Read Rate, Write Rate, Number Read, Number Write, Read Latency, Write Latency or All in the chart.

This view allows you to add alarms as an overlay to the Metrics Vs. Related Events view, and correlate the resource consumption with the stability of your environment.

CPU tab

This tab is available in the OpenStack Explorer. To find it, open the OpenStack Explorer and on the Topology tab that appears on the navigation panel, select a host. In the OpenStack Explorer, open the CPU tab.

The OpenStack Explorer’s CPU tab displays the CPU Usage for the selected host and the CPU Usage by Host Instances.

This view is made up of the following embedded views:

This view displays the amount of CPU each host used during a selected time period.

This view shows the amount of CPU the Host Instances used.

This view displays a list of all discovered Instances related to the selected host. The default view shows the combined CPU usage by all the instances on the selected host. The graph uses color to represent each instance. If you hover over a color on the graph, a pop-up identifies the instance associated with that color.

Clicking the Instance name in the Instance column takes you to a summary view showing resource utilization and configuration information for that instance.
