Viewing QoreStor statistics by using the CLI
An alternate method for viewing the current QoreStor statistics is by using the QoreStor 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
- Cleaner Status (current space reclamation process status)
- Compression Status (current compression 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 QoreStor CLI commands, see the QoreStor Command Line Reference Guide.
Monitoring system alerts
You can easily view current system alerts and events in the QoreStor GUI.
- To monitor system alerts, on the navigation menu, click 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, “QoreStor 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 connected to the QoreStor system. Client information can be viewed through the System Configuration page in the QoreStor GUI, or using the QoreStor CLI. .
Monitoring clients through the QoreStor GUI
- To view client information for QoreStor, on the navigation menu, click System Configuration.
The total number of currently active clients for a particular type is displayed at the bottom of the page.
- Client information is grouped by client type (RDA/OST, NFS/CIFS, NDMP, iSCSI, or FC). To view client information, click the appropriate pane to view information for that client type.
Monitoring clients through the QoreStor CLI
You can monitor client status through the CLI by using either the rda or ost commands.
To monitor clients, complete the following steps:
- Access the QoreStor CLI. Refer to Using the QoreStor command line for more information.
- View client information with the appropriate client command
stats –clients[--type <NFS|CIFS|OST|RDS|NDMP|ISCSI|FC>]
Refer to the QoreStor Command Line Reference Guide for more information.
Configuring and using Rapid NFS and Rapid CIFS
Rapid NFS and Rapid CIFS enable write operation acceleration on clients that use NFS and CIFS file system protocols. Similar to OST and RDS, these accelerators allow for better coordination and integration between QoreStor backup, restore, and optimized duplication operations with Data Management Applications (DMAs) such as CommVault, EMC Networker, and Tivoli Storage Manager. For the current list of supported DMAs, see the QoreStor Interoperability Guide.
Rapid NFS is a new client file system type that ensures that only unique data is written to QoreStor. It uses user space components and file system in user space (FUSE) to accomplish this. Metadata operations such as file creates and permission changes go through the standard NFS protocol, whereas write operations go through Rapid NFS.
Rapid CIFS is a Windows-certified filter driver that also ensures that only unique data is written to QoreStor. All chunking and hash computations are done at the client level.

NOTE: The supported DMAs listed in the QoreStor Interoperability Guide are the DMAs that have been tested and qualified with Rapid NFS and Rapid CIFS. You can use Rapid NFS and Rapid CIFS with other DMAs (such as Veritas products), but those products have not been tested and qualified with Rapid NFS or Rapid CIFS. |
