Viewing DR Series system statistics by using the CLI

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

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.

Monitoring clients

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.
◦
