V. Monitoring of VRTX
Monitoring of the VRTX chassis is more important than ever before, as it will
also roll-up the status of the shared storage components (controller and
drives). Many new defined storage events that are emitted by the chassis
controller will be recognized by OME v1.2 and the controller’s global status will
include the status of the PERC cards and the physical/virtual disks (to see
individual statuses, launch the CMC GUI and drill down to the Storage node).
Monitoring a device in OME includes the rolled-up status of the hardware,
typically viewed in the device tree, as well as the asynchronous events from
the device in the form of traps. In a Datacenter, the delivery of SNMP traps can
typically be trusted to be reliable – this is one reason the status polling interval
in OME can be kept at the default one hour interval or greater. However, when
managing devices over a WAN and/or sharing limited bandwidth with other
back office functions, the delivery of traps may not be as reliable. If traps
seem unreliable or not an option, it is recommended to set the status polling
rate to a shorter duration, but have an interval wide enough to not tax the
network. The default one hour may suffice in many cases. Additionally, OME
