Database The data collected by 3Com Network Director is logged using RRDTool. See “RRDTool” on page 395 for more information. This utility stores the data in round robin databases.

A round robin database is simply a file on disk, with extension .rrd. A new database is created for each monitored device or link.

All databases are located in the 3Com Network Director install directory, in a sub-directory called logging e.g.

C:\Program Files\3Com\3Com Network Director\logging

Located in this directory is a file called mapping.txt. This CSV file contains an entry for every device or link that has been monitored by 3Com Network Director now, or in the past. You can use this file to locate the database for a given device or link. The mapping file format is described in “Mapping file format” on page 395.
