Resource utilization checks#

Check disk space#

This procedure checks that there is enough disk space.

  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)

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

Check available RAM#

This procedure ensures that the RAM available per node 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.

  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.

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