Scenario 5 - Trend Analysis Example
The data provided by the NAM will make Dean’s life easier for real-time analysis and troubleshooting. But
wouldn’t it also be great to collect this data over time for trend analysis or historical reporting? All that is
needed is a database to store data collected by the NAM at regular intervals and then run reports on the data
over time. Well the NAM has this feature, allowing you to configure data collection to a database for up to
100 days!
Of course to gather data long term, the user must remember that if the SPAN, VACL, or NDE (Internal,
External, NDE on NM-NAM) data source containing the traffic you want to trend changes, then data can no
longer be collected to the database. Dean wants to view long term how much of the total link usage is
associated with Doom and Q-Bits Database development traffic. Let’s see how Dean creates historical
reports to trend the total byte rate of port Gi1/2 (currently spanned), and the byte rates of Doom and QbitsDB
traffic on VLAN 130.
