"Contact: Erlang Support see license agreement for Erlang/OTP."
DESCRIPTION
"This MIB is part of the OTP MIB. It defines MIB objects
for the os_mon application in OTP."
REVISION "0508260900Z"
DESCRIPTION
"Removed dependeny on EVA."
REVISION "0305090900Z"
DESCRIPTION
"Changed CONTACT-INFO as it was outdated, made it more generic
to avoid such changes in the future."
REVISION "9807080900Z"
DESCRIPTION
"Changed MAX-ACCESS for diskDescr from not-accessible to
read-only."
REVISION "9801270900Z"
DESCRIPTION
"Changed erroneous name of this module to otpOsMonModule."
REVISION "9712010900Z"
DESCRIPTION
"Converted to v2 SMI and placed in the OTP tree."
REVISION "9608191700Z"
DESCRIPTION
"The initial revision of MIB module OTP-OS-MON-MIB."
::= { otpModules 4 }
OTPCounterBasedGauge64 ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"The CounterBasedGauge64 type represents a non-negative
integer, which may increase or decrease, but shall never
exceed a maximum value, nor fall below a minimum value. The
maximum value can not be greater than 2^64-1
(18446744073709551615 decimal), and the minimum value can
not be smaller than 0. The value of a CounterBasedGauge64
has its maximum value whenever the information being modeled
is greater than or equal to its maximum value, and has its
minimum value whenever the information being modeled is
smaller than or equal to its minimum value. If the
information being modeled subsequently decreases below
(increases above) the maximum (minimum) value, the
CounterBasedGauge64 also decreases (increases).
Note that this TC is not strictly supported in SMIv2,
because the 'always increasing' and 'counter wrap' semantics
associated with the Counter64 base type are not preserved.
It is possible that management applications which rely
solely upon the (Counter64) ASN.1 tag to determine object
semantics will mistakenly operate upon objects of this type
as they would for Counter64 objects.
This textual convention represents a limited and short-term
solution, and may be deprecated as a long term solution is
defined and deployed to replace it."
