The Manager/Collector ``NeMaC''

NeMaC is a combined manager and collector for the NeTraMet meter. It is a simple Unix program, controlled via command line arguments. Parameters include the collection interval, rulefile name, configfile (determining which meters are to be controlled), SNMP community names and a number of optional operational parameters (like the flow timeout) for the NeTraMet meter which is to be managed.

While it is running, NeMaC generates a log file recording any unusual events observed for the meters being controlled as well as a ``flows'' file for each meter it controls.
