DESCRIPTION "This table is used to provide remote device monitoring

facilities.

This table allows a list of network devices to be set up and polled regularly
|

(or only once) by a variety of protocols. The table can be configured to inform
|
||||
the management station(s) of devices that are not responding to polls or that
|

have started to respond after a period of silence."

ACCESS read-write

|

DESCRIPTION "This defines the protocol with which to monitor the device.
|
||||
|
||||
Writing an address to the remPollAddress field causes a default remPollProtocol
|
||||
value to be setup. The default value is derived from the format/content of the
|
||||
address. If the requested protocol is not supported or is not compatible with
|
||||
the remPollAddress, then an error is returned when an attempt is made to set the
|
||||
remPollStatus to valid.
|
||||
|
||||
If the requested protocol is not supported then a badValue error
|
||||
should be returned. If the requested protocol is not compatible
|
||||
with the remPollAddress then an error is returned when an attempt
|
||||
is made to set the remPollStatus to valid.
|

DESCRIPTION "The time-out value in hundreds of a second for each request

|

DESCRIPTION "The number of unsuccessful requests necessary before

deciding that the device is definitely not responding.

remPollPeriod OBJECT-TYPE
|
||||
SYNTAX INTEGER (0..65535)
|
||||
ACCESS read-write
|
||||
STATUS mandatory
|
||||
DESCRIPTION "The device will be polled every remPollPeriod seconds. The
|
||||
first poll is sent as soon as the remPollStatus is set to valid(1). To prevent
|
||||
overlapping polls, the value of remPollPeriod must be greater than
|
||||
2*remPollTimeout*remPollAttempts - otherwise an error is returned when the row
|
||||
is set to valid.
|
||||
|
||||
A poll consists of sending up to remPollAttempts request packets to the device.
|
||||
A reply to any of the request packets is sufficient to declare the poll
|
||||
successful (and stop further requests from being sent). A poll is deemed
|
||||
unsuccessful if no replies have been received after
|
||||
remPollTimeout*remPollAttempts seconds from the start of the poll. Note: each
|
||||
request packet must contain some sequence information so that late replies do
|
||||
not result in a successful poll.
|
||||
|
||||
The first unsuccessful poll causes a PollFailure event to be generated - further
|
||||
unsuccessful polls do not generate events. The next successful poll to the
|
||||
device causes a PollSuccess event to be generated - further successful polls do
|
||||
not generate events. The pattern then repeats.
|
||||
|
||||
The value 0 has a special value meaning of only-once When remPollStatus is set
|
||||
to valid(1), a single poll is started immediately. There are no events
|
||||
generated. whether the poll has been judged successful or unsuccessful.
|
||||
|
||||
The results of the poll(s) can be monitored by reading the remPollLastRequest
|
||||
and remPolLastReply fields.
|
||||
|
||||
This object may not be modified if the associated remPollStatus object is equal
|
||||
to valid(1)."

DESCRIPTION "This is the value of sysUpTime at which the most recent
|
||||
request packet was sent.
|
||||
|
||||
To avoid temporary inconsistancies between the values of remPollLastRequest and
|
||||
remPollLastReply. The value of remPollLastRequest should not be updated until
|
||||
the end of a poll. At which point (a) remPollLastRequest is updated to the

sysUpTime when the most recent request packet was sent and (b) if the poll was

successful then remPollLastReply is also updated."

reply packet was received. The device was responding at this time.
|
||||
|
||||
The relationship of sysUpTime, remPollLastRequest and remPollLastReply provide
|
||||
the following information:
|

|

(sysUpTime - remPollLastRequest) = time since last request was made. (sysUpTime
|

- remPollLastReply) = time since device last responded.
