Foglight for OpenStack 5.7.4 - User Guide

Using Foglight for OpenStack Interacting with Foglight for OpenStack dashboards Reference

Summary tab

The Summary tab is available on OpenStack Explorer and appears on all views regardless of the resource object or group of objects chosen.

For more information about using the OpenStack Explorer dashboard, see Using the OpenStack Explorer dashboard .

Purpose and content

The Summary tab displays your OpenStack infrastructure resource objects.

Figure 44. OpenStack Explorer Summary tab

Each tile shows how many of the corresponding object types there are and the count of objects of that type in each of the alarm states (normal, warning, critical, fatal).

More detailed information for selected objects is displayed in collapsible views below the Summary tab.

On a tile, click the object type icon, the name, or the count, to view a pop-up that lists all objects of the corresponding type, along with their respective states. Click a column header on the pop-up to change the sort order. Click an object in the pop-up list to view details for that object in the OpenStack Explorer dashboard.

If an alarm state has a count of zero, then you cannot select that alarm state. If you click a normal state icon or count, the OpenStack Explorer page refreshes. No alarms are associated with the normal state.

Summary and Resource Information view

This view is available in the OpenStack Explorer display area. To find it, open the OpenStack Explorer and on the Topology tree on the navigation panel, select an individual Host, Instance, or Volume. In the OpenStack Explorer, open the Summary tab.

Purpose

The Summary and Resource Information view shows configuration details for the selected Host, Instance, or Volume.

System Info tab

This tab is available on the OpenStack Environment dashboard.

Figure 46. Summary Info tab with sub-tabs

Purpose and content

Displays summary data for the following OpenStack entities: Services, Images, Flavors, Networks, and Hypervisors.

Description of embedded views

The System Info tab is made up of the following embedded views:

•
Services
•
Images
•
Flavor
•
Network
•
Hypervisor
Services

This view displays a list of OpenStack services running on different hosts.

The table is includes the following fields:

•
Name — the name of a service installed on the OpenStack system.
•
Host — the node on which the service is installed.
•
Availability Zone — the location where the node resides.
•
Status — indicates if the service is enabled.
•
State — indicates if the service is running.
•
Disabled Reason — provides a description of why a service is disabled.
•
Updated at — provides the time the configuration information was last refreshed.
Images

This view displays the total number of image templates available for virtual machine file systems.

The table is includes the following fields:

•
Name — the name of the image.
•
Size — the size of image data, in gigabytes.
•
Visibility — indicates if the image is accessible to all members of a project.
•
Min Disk — the minimum size of the disk needed to boot the image, in gigabytes.
•
Min Ram — the minimum amount of RAM needed to boot the image, in megabytes.
•
Description — is a brief description of the image.

You can choose which columns to view by clicking the arrow in the upper right corner of the table and selecting which columns you want to see.

Flavor

This view displays the total number of flavors available identifying them by name. The table shows the amount of RAM, how many virtual CPUs an instance has, and the disk size.

When starting an instance, a set of virtual resources known as a flavor must be selected. Flavors define how many virtual CPUs an instance has, the amount of RAM and disk sizes.

The table is includes the following fields:

•
Name — name of an individual flavor.
•
RAM — virtual machine memory in megabytes.
•
vCpus — number of virtual CPUs presented to the instance.
•
Swap — optional swap space allocation for the instance.
•
rxtxFactor — optional property that allows created servers to have a different bandwidth cap from that defined in the network.
* 
NOTE: The default value of 1 is the same as the attached network.1
•
Disk — Virtual root disk size in gigabytes.
•
Disabled — Default value is false.
•
Public — whether a flavor is available to all users or private with True being the default.
•
Ephemeral — the size of a secondary ephemeral data disk that exists only for the life of the instance.
•
ExtraSpec — additional optional restrictions on which compute nodes the flavor can run on.
Network

This view displays the total number of network configurations for the OpenStack system.

The table is includes the following fields:

•
Name — network name.
•
Status — indicates if the network is operational.
•
Subnets — subnets associated with the network.
•
PhysicalNetwork — the name of the physical network.
•
AdminStateUp — the administrative state of a port.
* 
NOTE: false indicates that the port is not forwarding packets.
•
Project — project to which the network is associated.
•
NetworkType — the default network provider type and the only type of network projects are able to create.
•
External — indicates if the network is public or private.
•
Shared — whether any project can access the network resource.
•
SegmentationId — identifies an isolated segment on the physical network.
Hypervisor

This view displays the total number of hypervisors.

The table consists of the following fields:

•
Hypervisor Type — the type of hypervisor running on a host.
•
Host — the host running the hypervisor.
•
Node Name — name of the hypervisor node.
•
Node Ip — hypervisor’s IP, available for “Icehouse” and higher versions of OpenStack.
•
Hypervisor Version — the version of the hypervisor running on a host.
•
VCPUs — the total number of virtual central processing units (VCPUs).
•
RAM — hypervisor’s RAM.
•
Storage — hypervisor’s local storage capacity.

Topology tab

The Topology tab is located in the navigational panel at the left of the Foglight browser interface, under dashboards. For more information about the OpenStack Explorer dashboard, see Using the OpenStack Explorer dashboard .

Purpose

The Topology tab provides an organized view of the various OpenStack objects that agents are monitoring. It serves as a navigation tool, and it also presents pertinent alarm information.

Figure 47. Topology tab

When you select an object from the Topology tab, all the views in the OpenStack Explorer dashboard are updated with information pertaining to that object.

The topological view is organized into a tree using object type (or topology type) containers for branches.

The top-level objects in the topological view are always the Regions.

Each Region in the Topology view contains those objects in the OpenStack Infrastructure that are related to that particular Region.

At the right, the Topology view displays status indicators. For an individual object, the status indicator represents the alarm of highest severity that is outstanding for that object. For an object type container, the status indicator represents the alarm of highest severity that is outstanding for all the objects of that type.
