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.

    NOTE: When you first log on to the DR Series system GUI, you view the Dashboard page by default.

  2. You can view the following graphs:
    • 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:
    • Total number of files in all containers
    • Number of containers
    • Number of containers replicated
    • Active bytes–the total bytes before optimization.
    • Advanced data protection—the status of the data integrity check.
    • Cleaner status—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.
  5. To quickly view the state of the system, click the System Health Indicator icon, in the upper right corner of the DR Series system GUI. This icon appears green or red depending on the system state and displays the following information:
    • 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:

  • Capacity Used (system capacity used in Gibibytes or GiBs)
  • Capacity Free (system capacity free in GiBs)
  • Read Throughput (read throughput rate in Mebibytes or MiB/s)
  • Write Throughput (write throughput rate in MiB/s)
  • Current Files (current number of files in system)
  • Current Bytes (current number of ingested bytes in system)
  • Post Dedupe Bytes (number of bytes after deduplication)
  • Post Compression Bytes (number of bytes after compression)
  • Post Encryption Bytes
  • Post Encryption Bytes in GiB
  • Compression Status (current compression status)
  • Cleaner Status (current space reclamation process status)
  • Encryption Status
  • Total Inodes (total number of data structures)
  • Bytes decrypted
  • Dedupe Savings (deduplication storage savings by percentage)
  • Compression Savings (compression storage savings by percentage)
  • Total Savings (total storage savings by percentage)

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.

  • To monitor DR Series system alerts, on the left navigation menu, click Dashboard > Alerts.

    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.

    NOTE: For a detailed list of possibly occurring alerts, see the topic, “DR Series system alert and event messages,” in the “Support, maintenance, and troubleshooting” chapter of this guide.

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.

  1. To view client information for the DR Series system, on the left navigation menu, click Dashboard > Clients.

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

  2. To view NFS client information, click the NFS pane to expand it to view the following details:
    • 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.
  3. To view CIFS client information, click the CIFS pane to expand it to view the following details:
    • 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.
  4. To view RDS or OST client information, click the RDA pane to expand it to view the following details:
    • 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).
  5. To view NDMP client information, click the NDMP pane to expand it to view the following details:
    • 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.

  6. To view iSCSI client information, click the iSCSI pane to expand it to view the following details:
    • 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.
  7. To view iSCSI client information, click the iSCSI pane to expand it to view the following details:
    • 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.
  8. To view Fibre Channel client information, click the FC pane to expand it to view the following details:
    • Container Name—The container name of the FC VTL container.
