Defining SNMP Traps
Step 4 In the appropriate fields, enter the MIB name, frequency, test, sample type, threshold value, and
comments.
Note You can create valid triggers only on read-write and read-only MIB objects. If you create a
trigger on a read-create MIB object, it is deleted from the Central Manager configuration after
one one data feed poll cycle.
Test Test used to trigger the SNMP trap. Choose one of the following tests:
• absent—A specified MIB object that was present at the last sampling is no
longer present as of the current sampling.
• equal—The value of the specified MIB object is equal to the specified
threshold.
• falling—The value of the specified MIB object has fallen below the
specified threshold value. After a trap is generated against this condition,
another trap for this same condition is not generated until the sampled
MIB object value rises above the threshold value and then falls below the
falling threshold value again.
• greater-than—The value of the specified MIB object is greater than the
specified threshold value.
• less-than—The value of the specified MIB object is less than the specified
threshold value.
• on-change—The value of the specified MIB object has changed since the
last sampling.
• present—A specified MIB object is present as of the current sampling that
was not present at the previous sampling.
• rising—The value of the specified MIB object has risen above the
specified threshold. After a trap is generated against this condition,
another trap for this same condition is not generated until the sampled
MIB object value falls below the threshold value and then rises above the
rising threshold value again.
Sample Type (Optional) Sample type, as follows:
• absolute—The test is evaluated against a fixed integer value between zero
and 2147483647.
• delta—The test is evaluated against the change in the MIB object value
between the current sampling and the previous sampling.
Threshold Value Threshold value of the MIB object. This field is not used if absent, on-change,
or present is chosen in the Test drop-down list.
MIB Var1
MIB Var2
MIB Var3
(Optional) Names of up to three alternate MIB variables to add to the
notification. Validation of these names is not supported, so be sure to enter
them correctly.
Comments Description of the trap.
