Hello Zenoss Community
It would be useful, when viewing SNMP trap details, for the enumerate name of
trap varbind values to be displayed (rather than showing the numerical value
only).
Numerical values are good for event transforms (ie code) but enumerate names
are good for human operators.
I'll show an example trap here (from the event details tab of an SNMP trap
event)
Code:
Field Value
examplePowerSupplyStatus.0 brownOut(13)
Zenoss currently just displays
Code:
Field Value
examplePowerSupplyStatus.0 13
Certainly one can create an event transform to specifically handle the value 13
and update the evt.summary text. In reality, not every trap from every MIB
will have an event transform.
Adding the enumerate name from the MIB adds meaning to a trap that is yet to
have a specific event transform created for it.
For reference sake here is a MIB snippet from a Compaq hardware monitoring MIB.
Obviously the enumerate name/human readable word is of great use (given that
there is no event transform to specifically handle each of those values)
Code:
cpqHeFltTolPowerSupplyStatus OBJECT-TYPE
SYNTAX INTEGER {
noError(1),
generalFailure(2),
bistFailure(3),
fanFailure(4),
tempFailure(5),
interlockOpen(6),
epromFailed(7),
vrefFailed(8),
dacFailed(9),
ramTestFailed(10),
voltageChannelFailed(11),
orringdiodeFailed(12),
brownOut(13),
giveupOnStartup(14),
nvramInvalid(15),
calibrationTableInvalid(16)
}
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The status of the power supply."
::= { cpqHeFltTolPowerSupplyEntry 5 }
Apologies for the long and technical nature of this post.
