Using the Dashboard page

The Dashboard page contains graphics that show key information about the current state of the DR Series system. This page automatically refreshes every 30 seconds.

To use the Dashboard page, follow these steps.

1.
Click Dashboard in the left navigation menu of the DR Series system GUI.
Capacity—displays total used space, free space, and used and encrypted space in GBs and TBs.
Storage Savings—displays a total savings in percentage (combining both deduplication and compression) over a time period (for example, every hour, which is the default).
Throughput—displays the throughput volume (reads and writes) in Mebibytes/second (MiB/s) based on time (for example, every hour, which is the default).
System—displays information about memory and CPU usage.
3.
At the bottom of the Dashboard page, you can also view the System Summary section, which lists key information about the current DR Series system, including:
Active bytes–the total bytes before optimization.
Advanced data protection—the status of the data integrity check.

The current cleaner status as one of the following states:

Pending—displayed when there is any scheduled window set and the current time is outside the scheduled window for the Cleaner operation.
Running—displayed when the Cleaner operation is running during a scheduled window.
Idle—displayed only if there is no Cleaner operation running during a scheduled window.
4.
To change the time display in the graphs, click Zoom within the graph you want to view, and then select the time increment as hour, day, week, month, or year.
System State—displays the status value optimal, warning (a non-critical error has occurred), or actionable state (in which a critical error is detected.) To view more information about the System State, go to the Dashboard > Usage page, which displays current detailed status information for the system.
Hardware State—displays the status value optimal, warning (a non-critical error has occurred), or actionable state (in which a critical error is detected.) To view more information about the Hardware State, go to the Dashboard > Health page, which displays current detailed status information for the hardware and expansion shelf enclosures (if installed).
Alerts—displays the number of alerts that have occurred. You can click this number to view the alert(s).
Events—displays the number of events that have occurred. You can click this number to view the event(s).

Viewing DR Series system statistics by using the CLI

An alternate method for viewing the current DR Series system statistics is by using the DR Series system CLI command: stats --system. This command shows the following categories of system statistics:

For more information on DR Series system CLI commands, see the DR Series System Command Line Reference Guide.

Monitoring system alerts

You can easily view current system alerts in the DR Series system GUI.

The Alerts page displays a summary table of alerts listed by index number, timestamp of the system alert, and a brief message describing the alert.

Monitoring clients

You can easily view the current clients that are connection to the DR Series system. The Clients page displays a list of the clients that are connected to the DR Series system, which can include NFS, CIFS, RDA, OST, NDMP, iSCSI, and FC clients.

The total number of currently active clients for a particular type is displayed next to the client name in the individual client panes.

Name—the name of the NFS client.
Idle Time—the amount of idle time (non-activity) for the client.
Connection Time—the connection time for the client.
Name—the name of the CIFS client.
Idle Time—the amount of idle time (non-activity) for the client.
Connection Time—the connection time for the client.
Name — the name of the RDS or OST client.
IP Address—the IP address of the client.
Type—the type of RDA client.
Plug-in—the plug-in type installed on the client.
Backup Software—the backup software running on the client.
OS—the operating system of the client.
Idle Time—the amount of idle time (non-activity) for the client.
Connection—the number of connections for the client.
Mode—the current mode type that is set for the client, such as:
Auto: The DR Series system sets the deduplication as either Dedupe or Passthrough, based on the client’s number of cores and whether it is 32– or 64–bit.
Passthrough: The client passes all data to the DR Series system for deduplication processing (appliance-side deduplication).
Dedupe: The client processes hashing on data, so that deduplication processing occurs on the server side (client-side deduplication).
ID — the

NDMP session ID.

Duration — The duration of the current active session.
State — The current status, for example, Active.
Source — IP address of the source filer.
Target — The target tape drive being used for the current NDMP session.
Throughput — The current and average throughput.
Transfer size — The total size of data transferred in this backup session.
DMA — The IP address of the Data Management Application initiating the backup.

The NDMP Completed Sessions Statistics section shows the above information for any completed NDMP sessions.

Container Name—The container name for the iSCSI VTL container.
Container IQN—the iSCSI Qualified Name for the iSCSI VTL container.
Initiators Connected—the initiators connected to the iSCSI VTL container.
Container Name—The container name for the iSCSI VTL container.
Container IQN—the iSCSI Qualified Name for the iSCSI VTL container.
Initiators Connected—the initiators connected to the iSCSI VTL container.
Container Name—The container name of the FC VTL container.
