The widths for various columns in reports are defined in the amanda.conf file. If the data for a field exceeds the maximum width defined in amanda.conf, the display is truncated. You can change the maximum width. For example, to display longer hostnames, edit the amanda.conf file to define a wider column width for hostnames. If you edit amanda.conf to include the following entry:
columnspec "HostName=0:15"
See the description of the columnspec parameter in the amanda.conf man page for further information.
The Summary Report page will display hostnames of up to 15 characters.
