Resource Utilisation Checks

Check Disk Space

Purpose

To ensure that there is enough disk space.

Procedure

  1. Login to all nodes.

  2. Run the following command:

    diag disk

  3. Verify that the following disks are not over 85%:

    /
    /opt/platform
    /tmp
    /var/log
    /opt/platform/apps/mongodb/chroot/dbroot (this is only on unified nodes)
    

Step to Resolve

If any node is above the threshold, please clean if possible, else contact VOSS L2 support.

Check Available RAM

Purpose

To ensure that the RAM available per node is aligns with the scale of the platform.

Unified Nodes must be allocated a minimum of 8GB if the User count is less than 50 000, and 16GB for 50 000 or more. Each WebProxy should have a minimum of 4GB RAM.

Procedure

  1. Login to one node as platform.

  2. Run the following command:

    cluster run all diag free

  3. Verify that total RAM aligns with the scale of the platform. Note: the command above shows RAM in kilobytes.

Step to Resolve

If any node is below the threshold, please allocate more RAM to the virtual machine.
