Agents view commands

The Agents view shows a list of existing agent instances and a set of agent management commands at the top of the list. Use it to verify that your agents are collecting data from the monitored environment.
The following commands are available:
•
Add: Starts a workflow for creating new agent instances. For more information, see Configuring monitoring agents.
•
Refresh: Refreshes the list of agent instances and their states.
•
Activate: Activates one or more selected agent instances. Activating an agent instance starts the agent process on the machine on which the agent is installed.
•
Deactivate: Deactivates one or more selected agent instances. Deactivating an agent stops the agent process on the machine on which the agent is installed.
•
Start Data Collection: Starts the data collection for one or more selected agent instances. Starting an agent’s data collection causes the agent to begin monitoring the Hyper-V server and to send the collected metrics back to the Management Server.
•
Stop Data Collection: Stops the data collection for one or more selected agent instances. Stopping an agent’s data collection causes the agent to stop monitoring the Hyper-V server.
•
Edit Properties: Starts a workflow for editing the properties of one or more selected agent instances. Each agent comes with a set of properties that it uses to configure its correct running state. For more information, see Configuring agent properties.
•
Remove: Deletes the selected agent instance.
•
Version: Updates the agent package to the latest version.
 
* 
IMPORTANT: Updating the agent package using this command generates the previously existing credentials. However, if you update the agent package by re-deploying its .gar file through the Agent Status page, the credentials need to be re-created. To do that, select an agent instance, click Edit Properties, and configure the required credentials on the Credentials tab of the Edit Tab Manager dialog box.
Figure 3. Edit Tab Manager dialog box
To perform any of the available commands, select one or more check boxes in the left-most column and click the appropriate button. For example, to start an agent’s data collection, select the check box in the agent row and click Start Data Collection.

Agent tabs

The Agents area contains two tabs: Hyper-V Agents and SCVMM Agents. Each tab displays a list of the existing Hyper-V or SCVMM Agent instances and shows their status. Use it to verify if your agents are collecting data from the monitored environment.

Configuring monitoring agents

Foglight™ for Hyper-V uses the Hyper-V and SCVMM agents to collect information about your virtual environment:
•
Hyper-V Agents collect information from monitored Hyper-V servers. A Hyper-V server is a physical component required to begin building a virtual infrastructure. Hyper-V servers provide hypervisor-based architecture for controlling and managing resources for the virtual machines that run on it.
•
SCVMM Agents collect information from Virtual Machine Managers (VMM). A VMM allows you to manage host, networking, and storage resources when creating and deploying virtual machines to virtual clouds.
When Hyper-V and SCVMM agent packages are successfully deployed, you can create 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 Agents area on the Administration tab.
When you add an agent instance, the agent process is created on the Agent Manager host. Activating the agent instance starts that agent process. When you start an agent’s data collection, the agent process starts collecting data from the monitored host and to sends it to Foglight for Hyper-V.
To create, activate agent instances, and start their data collection:
1
Log in to the Foglight browser interface.
2
On the navigation panel, under Dashboards, choose Hyper-V > Hyper-V Environment.
3
On the Hyper-V Environment dashboard that appears in the display area, open the Administration tab.

The agent instances created to monitor the new host appear on the Administration tab, in the Agents area.
Close the dialog box. The Administration tab dashboard refreshes, showing the newly created Hyper-V Agent in the list.
15
If required, reconfigure the agent properties or credentials. For example, you can specify the name of the monitored Hyper-V server or the authentication schema.

On the Agent Management dashboard, select the agents whose data collection you want to start and click Start Data Collection.
18
Click Refresh
The Active and Data Collection columns show green check marks indicating that the agents are active and collecting data.
Figure 27. Agents activated and collecting data
If the agent unexpectedly fails or stops, this is an indicator of an incorrect configuration. Unknown host names or invalid WinRM configuration can cause the agent to fail. Incorrect configuration causes the agent to stop. If this happens, the agent generates an observation containing a message with more information about the failure.You can view the message contents in the Data Browser. For example, to find out any massages related to the Hyper-V Agent, in the Data Browser, navigate to Hyper-V > Hyper-V Agents > <Hyper-V Agent instance> > Messages > History > <message>. For more information about the Data Browser, see the Data Model Guide.

Configuring agent properties

The Hyper-V and SCVMM Agents collect data from your virtual infrastructure and sends it to the Management Server. The agents keep track of resource utilization metrics and alerts you when certain pre-defined thresholds are reached.
When an agent connects to Foglight, 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 Hyper-V. 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 Hyper-V and SCVMM Agent properties:
•
On the Hyper-V Environment dashboard, on the Administration tab, select an agent instance and click Edit Properties (see Configuring monitoring agents ).
 
* 
NOTE: This method only allows you to edit the Configuration properties, but not the 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 Hyper-V Agent properties, and is described in this topic.
For more information about working with agent properties, see the Administration and Configuration Help.
To modify the Hyper-V or SCVMM Agent agent properties using the Agent Status dashboard:
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
Open the Agent Status dashboard and navigate to the agent properties.
e
On the navigation panel, under Dashboards, choose Administration > Agents > Agent Status.
 
* 
IMPORTANT: Another way of editing agent properties is through the Agent Properties dashboard. The properties you specify on this dashboard apply to all instances of the selected type. To be certain that you are editing properties for a particular agent instance, without overwriting any properties of other agent instances of the same type, use the Agent Status dashboard instead of the Agent Properties dashboard.
f
On the Agent Status dashboard, select the instance of the Hyper-V or SCVMM Agent whose properties you want to modify, and click Edit Properties.
g
Indicate that you want to edit the properties of the agent instance.
A list of agent properties appears in the display area.
Figure 28. Hyper-V Agent properties
Figure 29. SCVMM Agent Properties
The position of the Properties pane depends on the dashboard you used to access agent properties. If you used the Agent Properties dashboard, the Properties pane appears to the right of the Namespace > Type pane in the display area. If you used the Agent Status dashboard, the Properties pane appears across the display area.
