SmartMIB Small Solution:

IP Datagram Statistics Report (Routing Process Utilization)

(SM-SmallSol00032)

Solution Overview:
 

This management solution focuses on detecting ONLY those devices that are designated as network Gateways and are indeed an IP Datagram forwarding devices.

The solution defines a module name and description, then initiates the polling process under which the Devices (or in a specified AMZ) are fed into the polling SNMP engine, where the Gateway status of the device is determined through polling the value of the ipForwarding MIB Object. A variable handler is then defined to store the value which is then tested with an IF conditional statement; if the status for the particular device is ‘Forwarding’ then the counters for the IP Datagram total inbound received, total inbound delivered to the IP process, forwarded, and inbound discarded are all collected along with the total IP Datagram outbound requests and outbound discarded. Collected statistics are then used to calculate higher level metrics to assess the health of router’s IP Datagram processes. Such higher metrics are:

• Percentage of IP Datagram delivered to the IP Process to the total inbound Datagram received.

• Percentage of IP Datagram discards due to no buffers.

• Percentage of IP Datagram distant to Remote Address destinations to the total inbound Datagram received.

• Percentage of IP Datagram Discards to the IP Process to the total outbound Request Datagram .

• Number of Routing Process Invocations.
