Using NFS disk space for performance data storage

Last Updated : Sep 23, 2022 |

Use Remote NFS storage for large capacity configurations to ensure adequate space is available for performance data storage. The NFS partition should be 30 GB or more.

Note:

The system administrator should monitor the daily report volume to determine the actual remote storage requirements. These requirements are based on the customer configuration and performance data parameters selected to record.

System Manager indicates data transfer completion by returning to the command prompt without displaying an error message. After the transfer completes, you cannot access the performance data from the old storage location.

Before changing the storage location, the System Manager verifies that the NFS is properly mounted on the local mount point and that the NFS server is accessible.

Important:

If you configured a NFS mount on System Manager for Session Manager Performance Data (perfdata) collection, then, if and when you reboot/boot System Manager virtual machine, you need to ensure that you manually re-mount the NFS store once the System Manager VM is up and you are able to log in to the VM through SSH. Failure to re-mount the NFS partition will result in the Session Manager perfdata to go, by default, into a folder which is in the root (/) partition of the System Manager file system. This might cause the partition to get full which in-turn might cause issues with the System Manager application.

Before you begin

  • On the NFS server, administer a user as admin and a group as admin and ensure that their UID and GID match the user admin and group admin of System Manager.

  • Set permissions on the NFS partition to be exported to 755 and assign the ownership of the NFS partition to the user admin and group admin.

  • If you have set up the NFS partition before Release 7.0, change the ownership of all the files and directories to user admin and group admin.

Procedure

  1. Log in to System Manager as a non-root user using SSH.
  2. Mount the NFS share. Run the following command:

    mountNFS_PerfData.sh server:directory

    where:

    • server is the Hostname, IP address, or fully qualified domain name of the NFS server.

    • directory is the path to the shared directory on the NFS server.

  3. On the System Manager web console, click Elements > Session Manager  > Performance > Data Collection.
  4. Click Disable All.
  5. On the SSH session, run the command move_to_perfdata-remote.sh to move existing performance data to the remote storage location.
  6. On the System Manager Performance Data Collection page, click Change Data Storage.
  7. Click OK and acknowledge the warning message.
  8. Select Remote (NFS) storage and click Commit.

    System Manager updates the Performance Data Collection page with the new storage location.

  9. Click Enable All to enable data collection for all Session Manager instances.
