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 16GB.
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.
