Foglight for VMware 5.8.1 - Installation Guide

Enabling VMware Performance Agents to collect data from a Virtual Center

Foglight™ for VMware uses the VMware Performance Agent to collect information from monitored environments. Each VMware Performance Agent can monitor an entire Virtual Center. To enable the agent to monitor your virtual environment, you must grant the agent privileges for accessing the Virtual Center and collecting data from it.

 
* 
IMPORTANT: Follow this procedure only if your environment does not include Foglight for Resource Optimization.

Configure these privileges on the Virtual Center using the VMware® Virtual Infrastructure Client.

First, you create a role and assign it privileges for browsing datastores, viewing and terminating sessions, and modifying performance intervals. Next, you assign that role to a user account that you want the VMware Performance Agent to use for accessing the Virtual Center. You will associate the selected user account with the VMware Performance Agent instance in a later step, when you configure the VMware Performance Agent properties (see Setting the Configuration properties ).

To grant a VMware Performance Agent privileges for collecting data from a Virtual Center:
1
In the VMware Virtual Infrastructure Client, on the tool bar, click Administration.
The Administration screen appears.

Configuring VMware Performance Agents for data collection

Configuring VMware Performance Agents for data collection

Foglight™ for VMware uses the VMware Performance Agent to collect information from monitored environments. Creating a VMware Performance Agent instance creates the agent process on the Agent Manager host. Activating the VMware Performance Agent starts that agent process, while starting an agent instance’s data collection enables the agent to start collecting data from the monitored Virtual Center and to send it to Foglight for VMware.

When the VMware Performance Agent package is successfully deployed, create one or more agent instances, activate them, and start their data collection. To perform these steps in a single operation for one or more monitored hosts, use the Administration tab of the VMware Environment dashboard.

Each VMware Performance Agent monitors a single Virtual Center. When you create a VMware Performance Agent instance and the Agent Setup wizard determines that the Virtual Center was not previously monitored by this Foglight instance, it starts importing historical data into Foglight. This data is not immediately available as it takes some time to collect it. This process can import data collected over 30 days or less, depending on the amount of data available in the Virtual Center. This allows you to explore VMware metrics as soon as the data is imported, instead for waiting for the agent to collect some data from the Virtual Center. The Metric History column in the Agents table indicates the progress of the historical data import. Historical data is intended for charting, trending, and general presentation purposes. It does not cause any alarms to fire.

To import Virtual Center historical data, the minimum recommended Virtual Center Statistics Levels must be at least 2 in the samples that are collected for one month for the agent to populate 30 days of historic collections. The following table lists the minimum Statistics Levels for all collection frequencies. For more information about Virtual Center Statistics levels, see your VMware® documentation.

Using an alternative method to create and configure VMware Performance Agents

The following procedure describes the process of creating and activating VMware Performance Agent instances and starting their data collection using the Agent Status dashboard. This dashboard is useful for creating agent instances one Agent Manager at a time.

Another way to create agent instances is using the fglcmd command-line interface. For more information about the available fglcmd commands, see the Command-Line Reference Guide.

To create, activate VMware Performance Agent instances and start their data collection using the Agent Status dashboard:
1
Log in to the Foglight for VMware™ browser interface.
2
On the navigation panel, under Dashboards, choose Administration > Agents > Agent Status.
The Agent Status dashboard appears in the display area.
Figure 24. Agent Status dashboard
3
On the Agent Status dashboard, click Create Agent.
The Create Agent wizard appears with the Host Selector page open.
4
Specify the monitored host that you want to use to monitor with the VMware Performance Agent.
In the Create Agent wizard, on the Host Selector page, select the system on which the Agent Manager is running, and click Next.
If the system name does not appear in the list, check that its Agent Manager is active and connected to the Management Server.
The Create Agent wizard refreshes, showing the Agent Type and Instance Name page.

IMPORTANT: If the VMwarePerformance agent type is not listed, you likely need to deploy the VMware Performance Agent package to that host. For more information, see Deploying VMware Performance Agent packages to monitored hosts .
5
On the Agent Type and Instance Name page, select VMwarePerformance.
6
Specify the name of the VMware Performance Agent instance that you are about to create.
•
To have Foglight for VMware assign a generic name, ensure that Generic Name is selected.
•
To use a specific agent name, select Specify Name, and in the Name box that appears, type the agent name.

Setting the VMware Performance Agent properties

The VMware Performance Agent collects data from the virtual infrastructure and sends it to the Management Server. The agent keeps track of resource utilization metrics and alerts you when certain pre-defined thresholds are reached.

When an agent connects to Foglight Management Server™, it is provided with sets of properties that it uses to configure its correct running state. Each agent is provided with a combination of two types of properties: agent properties and shareable properties.

Default versions of these properties are installed with Foglight for VMware. However, you can edit the default shareable and agent properties, configure agent properties that apply only to a specific agent instance, and create edited clones of shareable properties that are used by a subset of agents of a certain type.

There are two ways to access the VMware Performance Agent properties:

•
On the VMware Environment dashboard, on the Administration tab, select an agent instance and click Edit Properties (see Configuring VMware Performance Agents for data collection ). This method only provides access to the Configuration properties, but not the Black List and Data Collection Scheduler properties.
•
On the Agent Status dashboard, select an agent instance and click Edit Properties. This method provides access to the full set of VMware Performance Agent properties, and is described in this

For more information about working with agent properties, see the Administration and Configuration Guide.

To modify agent properties:
1
Log in to the Foglight browser interface.
2
Ensure that the navigation panel is open.
To open the navigation panel, click the right-facing arrow on the left.
3
Navigate to the VMware Performance Agent properties. An agent instance can have a combination of global and private properties. Global properties apply to all instances of the agent type, while private properties apply only to specific agent instances.
f
On the navigation panel, under Dashboards, choose Administration > Agents > Agent Status.
 
* 
IMPORTANT: Another way of editing the VMware Performance Agent properties is through the Agent Properties dashboard. The properties you specify on this dashboard apply to all instances of the VMware Performance Agent type. To be certain that you are editing properties for a particular agent instance, without overwriting any properties of other VMware Performance instances, use the Agent Status dashboard instead of the Agent Properties dashboard.
g
On the Agent Status dashboard, select the instance of the VMware Performance Agent whose properties you want to modify and click Edit Properties.
h
Click Modify the private properties for this agent to indicate that you want to edit the properties of the selected VMware Performance Agent instance.
A list of agent properties appears in the display area.
Figure 30. Agent Properties

The configuration of agent properties described in this section include:

•
Setting the VMware Performance Agent properties
•
Setting the Configuration properties
•
Setting the FileCollector properties
•
Setting the vSwitchCollector properties
•
Setting the Duplicate VM List properties
•
