Let's say that you want to monitor the total packets received by an SNMP device whose IP
address is 192.72.24.1. Then you would like to save this value every 60 seconds between 9:00 AM
and 5:00 PM. And if the rate is greater than 1000 per second, you want to save the value and at the
same time be informed of the situation through an audible alarm, such as a beep. Suppose you
consider this as a critical condition and would like to call it "Hot_1."
By checking the target SNMP device's MIB, you find that the variable ezRptrTotalFrames
contains the value that you need. Further, this variable belongs to the "EZ Stack 10" module.
(The term MIB module is synonymous to the term "MIB Name" in the MIB variable information
window of the MIB Browser.) Additional information you already know includes - index is equal to
the IP address of the target SNMP device and the community is equal to public.
