If you wish to cut down the number of files stored on disk, you can remove particular database files that correspond to devices or links for which you no longer need the data. You can do this by opening the mapping file and locating the entries for these devices and links. Each entry lists the file location under <InstallationDirectory>\logging, so you can selectively delete these files.

Alternatively open Windows Explorer at <InstallationDirectory>\logging and search for *.rrd files.

If you sort the results by Date Modified you can then remove the older files, as these are likely to correspond to devices/links that no longer exist, or have not been monitored for a long time.

Key Considerations

Troubleshooting Mapping file not updating

If you have the mapping file opened in an editor, or are reading it via a script, this may cause the file to lock, and 3Com Network Director may be unable to update it. If this occurs you should unlock the file by closing the editor or exiting the script respectively. Next time 3Com Network Director needs to update the file (when you start monitoring a previously unmonitored device or link), it will be updated to include any missing entries.

Changing the logging data directory

If you wish to change the logging data directory, for example, to a different partition from 3Com Network Director where there is more disk space available or that gets backed up regularly, you can do the following:

1Close down 3Com Network Director

2Locate the 3Com Network Director install directory for example

C:\Program Files\3Com\

3Navigate to the data\com\coms\wsd\tns subdirectory
