Investigating performance metrics

Investigating performance metrics

The VMware Explorer allows you to monitor a wide range of elements in your virtual infrastructure. It contains a number of informative views through which you can quickly and easily access detailed information about any of the available components (physical or virtual) within the infrastructure. Its hierarchical interface includes drilldown capabilities that display various performance metrics and alarms within the virtual infrastructure.

Figure 19. VMware Explorer

NOTE: The VMware Explorer dashboard is inventory-based. The VMware Explorer dashboard counts all virtual machines (VMs), including template VMs, for each vCenter. The Virtual Environment Summary dashboard is service-based. The VMware service created by Foglight® for VMware for a particular vCenter does not contain template VMs. Therefore, the number of VMs for a particular vCenter is different when you view it through the VMware Explorer dashboard than the number that appears when you view it through the Virtual Environment Summary dashboard.

To access this dashboard, from the navigation panel, under Dashboards, click VMware > VMware Explorer. For complete reference about the data appearing on this dashboard, see VMware Explorer views .

The VMware Explorer dashboard contains the following views: the Virtual Infrastructure view and VMware Explorer Primary view.

The Virtual Infrastructure view contains a navigation tree on the Topology tab that represents the various virtual infrastructure objects: Virtual Centers, Datacenters, Clusters, ESX Hosts, Resource Pools, and Virtual Machines. For each individual object or group of objects, a status indicator appears, showing the alarm of highest severity that is outstanding for the that object or objects. For example, there are 25 virtual machines configured for a vCenter. Twenty of the virtual machines have a normal status, three have a warning status, and two have a critical status. In the Topology view, the virtual machines container for that vCenter displays a critical status indicator to show that at least one of the virtual machines associated with the vCenter has an outstanding critical alarm.

Figure 20. Topology tab

The Hierarchy tab shows the logical layout of vCenter management servers.

Figure 21. Hierarchy tab

Hovering over an object in the Virtual Infrastructure view, you see a popup that provides a summary of the present state of that object.

Selecting an object or group of objects on either tab of the Virtual Infrastructure view displays performance details about your selection in the VMware Explorer Primary view. The VMware Explorer Primary view takes up the entire display area of the Foglight for VMware browser interface. This view provides significant value to administrators who leverage Foglight for VMware to monitor their virtual infrastructure.

The alarm summary in the top-right shows the number of alarms at each severity level that are outstanding for the selected object. Clicking an alarm count lists the active alarms for the object.

A set of tiles displayed along the top indicate the type of the selected object or objects, and the related alarm counts.

Additionally, a collection of navigation tabs appears in this view. These navigation tabs vary from object to object, but generally contain a tab to an object summary (typically the default view), a tab to an object performance overview, and one or more tabs to other relevant information.

The display area changes in appearance and content, depending on the selected object or group of objects. For example, if you select an object type container from the Topology view, the Summary tab displays a consumption graph and a table that are representative of the group of objects within that container.

However, selecting a Resource Pool container from the Topology tab displays a Resource Pools Relationship Tree on the Summary tab. This tree contains every resource pool that belongs to the clusters within the associated vCenter. This is useful if you want to see how those resource pools are laid out, or if you want to take a look at the utilization statistics for each configured resource pool on the vCenter.

If you select an individual resource pool from the Virtual Infrastructure view, the Summary displays summary and utilization information for that resource pool. This is typically the type of information you see on the Summary tab when you select any individual object from the Virtual Infrastructure view.

The metrics and the amount of detail displayed in the display area vary depending on the type of the selected object. For example, in the image below, the tiles indicate that the selected object is the New Datacenter datacenter, and that it is connected to one vCenter, one cluster, two ESX® Hosts, and so on.

The Utilizations view, typically located across the center of the display area tab, provides numerical and graphical representations of utilization metrics associated with the selected object or group of objects. For example, selecting a single resource pool from the Virtual Infrastructure view and opening the Performance tab in the display area, displays four graphs in the Utilizations view, showing CPU, memory, disk, and network resource utilizations for the selected resource pool.

From there, clicking a graph or a spinner shows a larger view of the graph with descriptive text about each metric appearing in the graph.

If you open the VMs tab for that same resource pool, the Utilizations view displays one graph illustrating the percent-used and percent-ready CPU utilization for the virtual machines of the resource pool.

If, however, you select a collection of ESX Hosts from the Virtual Infrastructure view and you open the Summary tab, an informative graph appears in place of a Utilizations view. Selecting a collection of objects in the Virtual Infrastructure view always shows a composite view displaying information about all object instances contained in that collection.

In addition to the Utilizations view, one or more Related Objects views may appear at the bottom of the display area. These views take the form of tables and list either the parent or child objects or both (whichever are applicable) of the object being viewed, and provide pertinent details about each one. Their appearance depends on the type and range of objects selected in the Virtual Infrastructure view.

For example, if you select a single cluster, two Related Objects views appear: one displaying the ESX hosts that belong to their cluster, and another listing the virtual machines running on those hosts. The views also display the performance metrics associated with each list item.

However, when you select a cluster container, the Summary tab shows a Related Objects view that lists all of the clusters in that container and provides pertinent details about each one.

Accessing VMware actions and tasks

The action panel operates like a drawer. Its default position is closed. To open the action panel, click the arrow at the far right of the Foglight for VMware browser interface.

The action panel provides you with easy access to a number of useful actions and tasks. However, it only provides additional Foglight for VMware related actions when you are viewing the VMware Explorer dashboard.

The following image shows an example of a typical VMware Explorer dashboard action panel.

Figure 34. Action panel

The actions available in the action panel vary depending on the object displayed in the VMware Explorer dashboard. The following actions are available from the VMware Explorer dashboard action panel:

Under the Actions heading, the Run Migration Modeler link takes you to the VMware Modeler dashboard, which provides you with a mechanism for viewing the impact that migrating a virtual machine will have on a target ESX Host.

For more information on the Migration Modeler, including specific instructions on how to run the Migration Modeler, see Planning for virtual machine migrations .

Under the Actions heading, the View Virtual Infrastructure Alarms link takes you to the vmAlarms dashboard. For specific information on the vmAlarms dashboard, see Exploring VMware alarms .

Under the Actions heading, the View Object IDs link takes you to the Object IDs dialog box. The Object IDs dialog box lists all of the objects in the virtual infrastructure with their type and object ID. The object IDs are the true names of the objects. To produce component-specific thresholds, context is required in the form of the relevant object ID.

To narrow down the list of objects, type a relevant text string in the search field provided and click Search. You can type things like a portion of the object type name (for example, server), a portion of the object name (for example, part of the IP address), or a portion of the object ID. To clear the Search box, click Clear.

For more advanced search options, click Advanced. To narrow down the list to objects of a particular type, type the object type name in the Type box. To find the object by name, type the object name in the Name box. To find the object by ID, type the object ID in the Object ID field.

Viewing baseline ranges

Foglight can estimate system performance by comparing metric values against a baseline range. A baseline establishes expected data patterns during a given time period. This feature is only available when your Foglight system includes a baseline cartridge with applicable metric definitions. Foglight for VMware uses the capabilities of the IntelliProfile cartridge, which enables the appearance of baseline data for ESX hosts and virtual machines on the VMware Environment and VMware Explorer dashboards.

Baseline data can also be displayed on custom dashboards and views for the following metric properties.

utilization

Start creating a custom dashboard by clicking Create dashboard on the action panel. From there, create a view and add one or more of the data elements listed above. For complete information about custom dashboards and how to get started, refer to the Foglight User Help and the Creating Custom Dashboards learning video.

Before finishing, edit the view properties and enable the appearance of the baseline minimum and maximum values by selecting one or more of the Show baseline min/max as check boxes.

When you finish creating the custom dashboard, the blue line in the chart indicates metric values over time, while the grey shaded area represents the baseline range for the selected metric.
