Monitoring device activity

You can use the Device Activity page to monitor data flows and data transfer rates for devices that are in use.

2
On the Device Activity page, you can view the following information.

Device activity

This area shows data transfers from clients to jobs on the left and jobs to storage devices on the right. Gray lines depict data flow; the thicker the line, the higher the rate of flow. Boxes represent clients, jobs, and devices; the taller the box, the higher the rate of flow.

You can use the following settings available in the Detail area to modify the data flow view:

Devices: Select this option to view data transfers from all jobs to a storage device.
Job groups: Select this option to view data transfers from a job group (plug-in or policy) to a storage device. The job group can be selected in the Grouping list.
Job: Select this option to view data transfers from client to jobs and from jobs to storage devices.
Focus and Un-focus: Use these buttons to show and hide data flow details for a specific device. Click the device box, and click Focus. To hide the details for that device, click Un-focus.
Pause and Play: Use these buttons to pause and resume data flow updates. To stop data flow updates, click Pause, and to resume updates, click Play.

The transfer rate shows “unknown” for backups running on older NetVault Backup Clients.

Summary

This area shows the following information: total active transfers, active clients, active devices, current overall throughput, hottest transfer, and hottest target.

You can click a box representing the client, job, or storage device in the Device Activity area to view information about that component.

Modifying DR Series System settings

You can modify the user password or stream limit for an existing DR Series system.

Click Update, and in the Update Device Details dialog box, modify the required settings.

Username

Specify a user account that can be used to log on to the device.

On the DR Series system, only one user account exists, and the user ID for that account is backup_user. You can only change the password for this account; you cannot create an account or delete an existing account.

Password

Type the password for the user account.

Stream Limit

The default value for this setting is 32 streams. This setting applies to all NetVault Backup Servers to which the container is added. If the number of data streams exceeds the defined limit for the container, the Media Manager reports an error (“Device has too many streams”).

You can set the soft stream limit to any value between 1 and 256.

If the container is added to more than one NetVault Backup Server, set the same soft stream limit on all servers.
