Managing Agents

After you create agents, you can check their status and alarms. Over time, you may need to edit configured agents. You complete these tasks on the Storage Environment dashboard under the Administration tab.

This section covers the following tasks:

•
Reviewing the Status of Configured Storage Collector Agents
•
Reviewing Agent Alarms
•
Editing Configured Agents
•
Deploying Storage Agents after an Upgrade

Reviewing the Status of Configured Storage Collector Agents

The Storage Collector Agents view displays all Storage Collector agents, their status, and current alarms on that agent.

If the Configured box is not checked, some aspect of the configuration is incorrect. The agent has not validated successfully and is unable to collect data. To correct the configuration, see Editing Configured Agents.

Reviewing Agent Alarms

The Agent Alarms view shows the alarms that have been triggered, but not cleared for the Storage Collector agents. Failure to fix a chronic problem may cause the agent to stop collecting data. Note the following:

•
A Storage Collector agent alarm typically indicates a collection failure, and provides the reason for the failure.
•
A typical failure cause is that a password has been changed for a storage device, but the password in the associated credential has not been changed, leading to an authentication failure.
•
If you frequently get an alarm indicating a collection has timed-out, consider changing the agent schedule to collect less frequently. The Status panel on the Edit Agent Properties dialog box displays the duration of the last collection.

From this table you can select an alarm to view the alarm details.

To view alarm details or administer alarms:
1
Click on the required alarm.
The alarm message box opens.
2
After performing the required task, click Cancel.
The alarm message box closes.

Editing Configured Agents

The Edit Agent Properties dialog box provides the following functions for all configured agents:

•
View collection times and status.
•
Assign/Edit credentials.
•
Validate device connectivity.

The following functions are provided if relevant for a specific device type:

•
Edit port or path properties.
•
View the target devices being collected via a management host.
•
Enable/disable the collection of specific arrays via a management host.
•
Hitachi—enable/disable the use of the Tuning Manager.
•
CLARiiON using CLI—discover arrays in new domains.
•
Discover new arrays/switches in the environment using the Validate Connectivity function.
To edit Foglight for Storage Management Agent properties:
•
Click the Edit icon to the left of the Agent Name to open the Edit Agent Properties view.
The Agent Properties Editor page opens.
From the Edit Properties dialog box, you can perform the following tasks:
•
Reviewing Agent Status and Validating Connectivity
•
Managing Credentials
•
Managing Discovered Switches and Arrays
•
Managing CLARiiON Domains and Arrays
•
Managing the Hitachi Tuning Manager
