Agents view

Purpose

This view displays a list of the existing VMware Performance Agent instances and shows their status. Use it to verify that your agents are collecting data from the monitored environment.

Figure 88. Agents view

How to Get Here
1
On the VMware Environment dashboard, open the Administration tab.
The Agents view appears at the bottom of the Administration tab.
 
Description of the View
Data displayed
•
Active. Indicates if the VMware Performance Agent process is running.
 
•
Agent Name. The name of the VMware Performance Agent instance.
 
•
Agent Version. Indicates if the agent is running the latest version of the agent package (), or it needs to be updated ().
 
•
Alarms. The total numbers of Warning, Critical, and Fatal alarms.
 
•
Data Collection. Indicates if the VMware Performance Agent is collecting data from the monitored environment.
 
•
Download Log. Allows you to download the agent log file.
 
•
Edit Properties. Allows you to edit the agent’s properties.
 
•
Foglight Agent Manager Host. The name of the machine on which the Agent Manager and the VMware Performance Agent process are running.
 
•
Metric History. The progress of the import of historical data. 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. Historical data is intended for charting, trending, and general presentation purposes. It does not cause any alarms to fire.

Click this column to start a metric history import, or to see its progress. When the import is in progress, you have an option to cancel it, if needed.

Click Cancel in the dwell to cancel the import. You can resume it at a later time.

When the metric history import is completed, this is indicated in the dwell.
