SNMP Trap: Disk Status
----------------------

For ``ERROR: Disk full``:

Identification

* The originating IP / hostname is used to identify the system generating the traps
* The NMS is responsible for associating traps with each managed system, 
  along with clearing of alarms and escalation to the relevant system operator
* The trap OID is generic  for various SNMP events monitored by the system
* The SNMP system name is included as part of the variable binding to assist identification. 

Severity Messages
.................

* Info : DISK STATUS: Disk <disk> is now running below 80 percent
* Critical : ERROR: Disk full, DISK ALMOST FULL: Disk <disk> is more than 80 percent full


Example: ERROR: Disk full

Resolution:

This trap depends on which disk is full:

* If it is the ``media`` or ``backup`` disks, then clean up the disk space. 
* If it is any other disk then contact Support immediately.
