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.

Modification
The ospf v2protocol and ospf v3protocol keywords were introduced
to support the creation of OSPF threshold monitoring templates. OSPF
attribute values were introduced for threshold monitoring.
Removed support for MPLS interfaces.
The interface basic-counters keyword was added to support the creation of
threshold monitoring template for the basic counter.
Calculation
—
16 - 10 = 6, which is > than 50
percent of 10
20 - 16 = 4, which is not > than 50
percent of 16
35 - 20 = 15, which is > than 50
percent of 20
