Modification
Release
The
ospf v2protocol
and
ospf v3protocol

attribute values were introduced for threshold monitoring.
Release 3.2
Removed support for MPLS interfaces.
Release 3.3.0
The
interface basic-counters

threshold monitoring template for the basic counter.
Release 4.0.1
Usage Guidelines
Use the
percent
argument to specify a value that is relative to the previous sample's interval value. When
you use the
percent
argument with a
value
of 50, the calculation is performed in this manner, assuming
that your current sampled value is sample1 (S1) and the value sampled in the previous sampling period is
sample 0 (S0):
(S1 - S0) GT 50% of S0
For example, if you wanted to check for an increase of 50 percent in the counter BGPInputErrors, you could
use the following
attribute
and
operation
with the
percent
argument:
BGPInputErrors GT 50
This table shows threshold behavior, assuming the values for BGPInputErrors are at consecutive samplings.
