9 PERFORMANCE REPORTING

Overview	This chapter describes the logging and reporting of data within 3Com
	Network Director.
	3Com Network Director uses monitoring to track the health of your
	network and spot problems as they occur. One of the functions
	performed by 3Com Network Director is to collect this monitored data
	and log it to disk. This gives you the ability to produce reports on devices
	and links, that show the health of your network over a period of time,
	and when particular problems occurred. You can also use these reports to
	see how network usage changes over a period of time.
	See “Monitoring the Network” on page 273.

Key Concepts

Automated logging Whenever you start monitoring an item, 3Com Network Director automatically logs all collected data in a database. When you stop monitoring an item, data collection is stopped. In this way you can control what parts of the network to monitor for long-term data collection. Logging data from an item adds no extra overhead to 3Com Network Director in terms of collecting live data from your network.
