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 for multinode unified topology
    database nodes for modular cluster topology)

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.

  • Multinode unified topology: unified nodes must be allocated a minimum of 16GB.

  • Modular cluster topology: application nodes must be allocated a minimum of 16GB.

  • Modular cluster topology: database nodes must be allocated a minimum of 32GB.

  • 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.
