tcaSampleType
Module: TCAv2-MIB
OID (symbolic): TCAv2-MIB::tcaSampleType
OID (numeric): 1.3.6.1.4.1.148.1.5.1.1.1.6
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The value of this object is the sample type of
the object being thresholded from the
perspective of the CNM or XA-OM customer.
This object can be used for the following
data types:
(a) Counters
(b) Counters measured over certain intervals,
where the Counters are reset to zero at the end
of the interval and as a result have the
syntax Gauge.
(c) Gauges (other than (b))
(d) (Enumerated) INTEGER
(e) (Enumerated) INTEGER that is used as a bitmap.
The enumerated values of this object apply to
these data types as follows:
| possible values |
data type | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
--------------------+---+---+---+---+---+---+---+---+
(a) Counter | | X | | | | | | |
(b) IntervalCounter | X | | | | | | | |
(c) Gauge | | | X | X | | | | |
(d) Enum INT | | | | | X | X | | |
(e) Enum INT(bitmap)| | | | | | | X | X |
--------------------+---+---+---+---+---+---+---+---+
(a) Counter values can only rise. An
alarm may be triggered when the value has
risen a delta amount within a sample period.
(b) IntervalCounter values can only rise within an
interval and are reset at the end of the
interval. An alarm may be triggered when
the value has exceeded an absolute value.
(c) A Gauge value may rise and fall. An alarm
may be triggered when the value has risen or
fallen a certain amount.
(d) An INTEGER may assume values in any sequence.
An alarm may be triggered when the value
does equal or doesnot equal a certain
specified value.
(e) A bitmap may assume values that represent
one or more bits to be set. An alarm may be
triggered when the value does include or not
include the combined value of certain bits.
Note that for (c), (d), and (e) only one alarm
needs to be generated, i.e., at first detection
of this event.What is tcaSampleType?
This read-only enumerated object indicates how the monitored counter should be interpreted for thresholding purposes, distinguishing plain counters, interval counters, gauges, and enumerated integers (including bitmaps), each evaluated differently per the MIB's documented table. Admins rely on this to understand whether a threshold alarm fires on a rising delta, an absolute value, a rise-or-fall, or an equality/bitmap match, since the alarm logic differs by type. A tcaSampleType of intervalDeltaValue(2) tells the admin the associated TCA fires based on how much a counter rose within a sampling interval, not its raw cumulative value.
