To monitor the data points of an SNMP device or entity, you must add them to the
device or entity in Security Center.
Before you begin
Best Practice: For optimal performance of the plugin, it is
recommended to limit the number of data points and rules to 5000
respectively.
What you should know
You can only add the data points contained in a static SNMP table by specifying
their index in the table. Changes to the table by the SNMP agent at runtime could result
in an invalid data point.
