Viewing container statistics

Displaying container statistics by using the CLI

In the DR Series system GUI, you can view statistics about a selected container. All statistics displayed represent specific information about the backup data, throughput, replication, marker type, and connection type for the selected container. The displayed statistics will vary depending upon the connection type used by the specified container.

To display container statistics for a selected container, complete the following steps.

1.
On the left navigation menu, click Containers, and then select the storage group that contains the container you want to view. (If you are only using the DefaultGroup storage group in your DR Series system, you do not need to select a group.)
The Containers page is displayed.
2.
In the list of containers, select the container for which you want to view statistics, and then click the Chart icon.
3.
In the Active and Throughput charts, you can view current statistics for the container.
The Active chart displays the number of active files ingested based on time (in minutes), and the number of active bytes ingested based on time (in minutes). The Throughput chart displays the number of read data in Mebibytes/per second (MiB/s) based on time (in minutes), and the number of write data in MiB/s based on time (in minutes).
* 
NOTE: The values in the Active and Throughput charts refresh automatically every 15 seconds.
4.
In the Backup Data and Throughput panes, click Zoom to select the duration period you want to display.
5.
You can view the following additional information about the container.
◦
Marker Type—the marker type associated with the container.
◦
Connection Type—the configured connection type for the selected container, which can be NFS, CIFS, NDMP, iSCSI, FC, RDS, or OST. The type of connection information displayed for the container can vary based on connection type.
◦
Total Files—the total number of files in the selected container.
6.
In the Connection information pane, you can view information about the configured connection type for the selected container which can be NFS, CIFS, NDMP, iSCSI, FC, RDS, or OST. The type of information displayed can be different depending on the connection type. For example, the following information is displayed:
◦
NFS Connection Configuration pane—NFS access path, Client Access, NFS Options, Map root to, and NFS Write Accelerator (DR6000 only).
◦
CIFS Connection Configuration pane—CIFS share path, Client Access, and CIFS Write Accelerator (DR6000 only).
◦
If the container is an RDA connection type container, the Connection Type OST pane or Connection Type RDS pane displays the following information:
▪
Capacity — displays a Capacity pane with Status, Capacity, Capacity Used, and Total Images
▪
Duplication
— displays a Duplication Statistics pane with Inbound and Outbound statistics in the following categories: Bytes Copied (logical), Bytes Transferred (actual), Network Bandwidth Settings, Current Count of Active Files, and Replication Errors.
▪
Client Statistics — displays a Client Statistics pane with Images Ingested, Images Complete, Images Incomplete, Images Restored, Bytes Restored, Image Restore Errors, Image Ingest Errors, Bytes Ingested, Bytes Transferred, and Network Savings.

Displaying container statistics by using the CLI

An alternate method for viewing container statistics is by using the DR Series system CLI command: stats --container --name <container name>

This command shows the following information:

•
Container Name (name of the container)
•
Container ID (ID associated with container)
•
Total Inodes (total number of data structures in container)
•
Read Throughput (read throughput rate in Mebibytes or MiB/s for container)
•
Write Throughput (write throughput rate in MiB/s for container)
•
Current Files (current number of files in container)
•
Current Bytes (current number of ingested bytes in container)
•
Cleaner Status (current space reclamation process status for the selected container)

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

Managing replications

Managing replications

Guidelines and prerequisites for replication
Viewing replication information
Adding replication relationships
Modifying replication relationships
Deleting replication relationships
Starting and stopping replication
Adding a cascaded replica
In the DR Series system GUI, you can set up and manage data replication operations. Such replication operations include, creating new replication relationships, managing or deleting existing replication relationships, starting and stopping replication, and displaying current replication statistics.

Guidelines and prerequisites for replication

Refer to the following important notes and guidelines for understanding and using replication in the DR Series system.

•
TCP Port Configuration—If you plan to perform replication operations across a firewall, the DR Series system replication service requires that the following fixed TCP ports be configured to support replication operations:
◦
port 9904
◦
port 9911
◦
port 9915
◦
port 9916
•
DMAs and Domain Relationships

— To allow replication storage information to be viewed by a corresponding data management application (DMA), the target DR Series system must reside in the same domain as the source DR Series system in the replication relationship.

•
Replication Limits —

Refer to the DR Series System Interoperability Guide for details about the supported system limits for replication per DR Series system model. For a definition of connections and streams, see Streams_vs_Connections.

•
Version Checking — The DR Series system software includes version checking that limits replication only between other DR Series systems that run the same system software release version. If versions are incompatible, the administrator will be notified by an event, and replication will not continue.
•
Storage Capacity and Number of Source Systems — Be aware that the storage capacity of the target DR Series system is directly affected by the number of source systems writing to its containers, and also by the amount being written by each of these source systems.
•
MTU Setting — Primary and secondary replication targets should have the same network maximum transmission unit (MTU) setting. See the topic, “Configuring Network Settings,” for more information about this setting.
* 
NOTE: Rapid Air Gap is a replication feature in which a secondary target DR Series system in a three-way replication scenario exists in an isolated private network. This solution is available for use with NetVault Backup 11.4.5. The DR Series system secondary target can be hosted with limited set of services. All other services are closed, securing the DR Series system appliance from the external environment. The Secondary target is available for replication for only a specific period of time (when the Air gap closes). And, only during this period of time will replication between the Primary and Secondary target DR systems occur. Commands for using this feature are available in the DR Series system command line interface (CLI). For information about setting up and using the Rapid Air Gap feature, see the DR Series Air Gap Setup Guide and the DR Series System Command Line Reference Guide.
