Many different devices report SNMP values in tables. The instances from
these tables are used by OverTime to identify the information you want to
collect. Sometimes, the device renumbers these instances and unless the
collections are also adjusted then data for the wrong object is collected. ottrack
provides a way to keep dynamically align the collected data based on some other
referenced information.
Suppose you had traffic information coming in on interfaces represented
by OID instances and the device could change these instances but the interfaces
could be identified by their unique MAC address that the device synchronized with
the new instances. Keeping track of the unique MACs would identify how the old
instances related to the new. ottrack will do this.
