NAM Performance Considerations
The NAM offers a wealth of data and reports that give you visibility into your network. The next section shows
you how to choose from among the data sources available to you and how to tailor the NAM monitoring and
reporting functions to meet your specific needs. While we go through the setup section and, more
importantly, while you develop your NAM usage plan, keep in mind that the NAM has fixed resources and all
of the monitoring reports, alarms, and captures you define are stored in the NAM memory (which is currently
512 MB for the NAM-1 and NM-NAM, and 1 GB for the NAM-2). So all of the ways the NAM delineates data
for the monitoring and reporting you choose, and all of the packets you capture for decode will consume
memory.
Be aware that the more traffic you collect, the more NAM resource you are consuming. So, choose your
data sources and your monitoring and reporting needs wisely to ensure that you maintain the validity of your
data. A good practice is to slowly and incrementally add data collection and monitoring options and then view
their impact on the NAM by viewing system resource utilization in the Admin > System > System
Resources menu.
