Activating the agent

After you create the agent instance and define the proper credentials, you can enable the agent to start the data collection:

1
On the navigation panel, navigate to Dashboards > Administration > Agents > Agent Status.
2
Select the agent that you want to activate, and click Activate.
 
* 
TIP: The activate operation fails if the credentials are not properly defined. Click Get Log to see the list of errors and warnings.
 
* 
NOTE: You can also create/activate an agent when adding a monitored host. For more information, see Adding a monitored host.

Monitoring the infrastructure

After activating the agent, you can start monitoring your infrastructure environment. If your agent is configured correctly, the Hosts dashboard should now display the data being collected.

To access the Hosts dashboard:
•
On the navigation panel, under Dashboards, click Infrastructure > Hosts > Hosts.
Figure 9. Hosts dashboard

 
* 
NOTE: The Add Host icon and the Monitored column are available only if Foglight for Infrastructure is installed.

The Monitored column shows whether the host is already configured for monitoring , or is not monitored yet (in which case, you can click the icon to add a monitored host).

Once sufficient data has been collected, the CPU (Utilization, Current), Memory Current, Disk (I/O, Usage), and Network Current columns and the Utilization sparklines display the resource utilization for each monitored host. Hover over each of these columns to see the resource utilization graph for a host.

Adding a monitored host

The Add Monitored Host wizard allows you to add different types of hosts to the list of components being monitored in your infrastructure environment.

You can launch this wizard from several places in the Foglight browser interface:

•
From the Infrastructure Environment dashboard, by clicking Single Host in the upper-right corner.
•
From the Infrastructure Environment dashboard > Monitoring tab > Resource Utilizations view. If a host is not being monitored, the Resource Utilizations view displays a warning message. You can add the selected host to the list of monitored hosts by clicking Configure Host Monitoring .
•
From the Hosts dashboard, by clicking Add Host , or (for a known but unmonitored host) by clicking the icon in the Monitored column.
To add a host using the Add Monitored Hosts wizard:
1
In the Add Monitored Host wizard, on the Host and Agent Manager page, specify the host that you want to monitor.
•
Remote Host: Type the host name or the IP address of the host you want to monitor. If you clicked the Monitored icon for an unmonitored host, this box already contains the host name.
 
* 
NOTE: This value must resolve to a real host name or IP address in order to pass the credential validation test in Step 3.
•
Optional Settings: Expand this area and type the host name that you want to override the previously specified host. This step is optional.
•
Agent Manager: Select the agent manager that you want to use to collect the information about the remote host. The list includes only the Foglight Agent Managers to which the Foglight for Infrastructure agent package is deployed.
•
OS Type: Select the OS type of the remote host that you want to monitor: Windows, *nix (HP-UX, AIX), Linux, or Solaris.
 
* 
NOTE: The wizard uses the specified OS type to determine what agent type to create, WindowsAgent or UnixAgent. This box appears disabled if the wizard is invoked by selecting a host when its OS type is known.
•
Virtual / Guest: Ensure this check box is disabled.
* 
NOTE: Ability to monitor virtual hosts is currently implemented only in Foglight™ for Virtualization, Enterprise Edition. For information about how to configure a virtual agent, refer to the Foglight™ for Virtualization, Enterprise Edition documentation.
2
Click Next.
The host name is validated.
If the host name does not resolve to a real host name, the message Unable to locate host using the provided host name appears in the Validation Result dialog box. Click Cancel and return to Step 1 to define a valid host name or IP address.
If the host name passes the validation test, the Add Monitored Host wizard refreshes, showing the Agent Properties page. The layout of the page is different for WindowsAgents and UnixAgents.
•
WindowsAgent
•
*nix (HP-UX, AIX) Agent
•
LinuxAgent
•
Solaris Agent
 
* 
NOTE: If you selected the Virtual/Guest check box in Step 1, the Collect Metrics check boxes are disabled, preventing the agent from collecting these type of metrics.
3
On the Agent Properties page, specify the properties of the monitoring agents. For complete information, see Creating agent instances. Click Next.
The wizard checks whether the Agent Manager has any credentials configured for this host, and displays the findings on the Credential Verification page. Matching credentials are those with a resource mapping that matches the host to be monitored.
 
* 
NOTE: Credentials are security data that provide the Infrastructure agent with the permission to monitor system resources, such as a host or a range of hosts.
If the selected host name matches the host on which the Agent Manager is running, that is indicated on the Credential Verification page.
If any matching credentials are found, they are displayed in table format. The result of the validation is displayed in the Test column.
•
If the test fails, click the FAILED link to open a dialog box that displays additional information about the issues encountered during the validation, and helps you troubleshoot the root of the problem.
•
If the test is successful, the SUCCESS link appears in the Test column.
 
* 
TIP: When several credentials are available for a resource, the list of credentials is ordered with the most applicable credentials at the top. The ordering is based on a relative ordering value assigned to each credential.
If no matching credentials are found, that is indicated on the Credential Verification page.
4
On the Credentials Verification page, select one of the following options:
•
Do not configure a credential: Select this option if you want to configure the credential for this resource at a later time. Local credentials for Windows® and UNIX® are set up by default when Foglight for Infrastructure is installed. Click Next and continue with Step 7.
•
Add host(s) to a new credential: Select this option if you want to add the host to a new credential. This option is suitable if none of the existing credentials have the connection details needed to access the new host. Click Next and continue with Step 5.
•
Add host(s) to an existing credential: Select this option if you want to add the host to an existing credential. This option is suitable if an existing credential has the security data needed to access the new host, but you need to edit its resource mappings to include this host. Click Next and continue with Step 6.
•
If the selected host name matches the host on which the Agent Manager is running, click Next and continue with Step 7.

c
On the Credential Properties page, type the required properties, and click Next.
The Credential Name and Lockbox page appears.
d
On the Credential Name and Lockbox page, provide a name to identify the credential, and select a lockbox in which you want to keep the credential. A lockbox can be used to group credentials for access and/or security. In smaller Foglight installations, using the default System lockbox should be sufficient.
 
* 
NOTE: If a lockbox is password protected and is not released to the target Foglight Agent Manager, you can provide the lockbox password on the last page of the wizard.
Click Next.
The Resource Mapping page appears.
e
On the Resource Mapping page, indicate which hosts you want to associate with this credential. You can either select the host that you are about to start monitoring, all monitored hosts, or hosts whose name contains a specific text string.
Click Next.
The Policies page appears.
f
Optional. On the Policies page, define one or more policies for this credential. A policy defines the number of times a credential can be used, the number of allowed authentication failures, the time range during which the credential is valid, or the length of time the credential data can be cached on the client. For example, you can specify the number of times the credential can be used, or the time period during which it can be used. For complete information about the available credential policies, see the Administration and Configuration Help.
