For all Lustre components, the SNMP module reports a number and total and free
capacity (usually in bytes).
Depending on the component type, SNMP also reports total or free numbers for
objects like OSD and OSC or other files (LOV, MDC, and so on).
The Lustre SNMP module provides one read/write variable, sysStatus, which
starts and stops Lustre.
The sysHealthCheck object reports status either as healthy' or 'not healthy' and
provides information for the failure.
The Lustre SNMP module generates traps on the detection of LBUG
(lustrePortalsCatastropeTrap), and detection of various OBD-specific healthchecks
(lustreOBDUnhealthyTrap).
