34 \fIamdump\&.1\fR) and translates the information into a picture format that may be used to determine how your installation is doing and if any parameters need to be changed\&.
38 lines that it either does not understand or knows to be warning or error lines and a summary of the start, end and total time for each backup image\&.
41 is a shell script that executes an
44 (\fIamplot\&.awk\fR) to scan the
46 output file\&. It then executes a
49 (\fIamplot\&.g\fR) to generate the graph\&. The
51 program is written in an enhanced version of awk, such as GNU awk (\fBgawk\fR(1)
52 version 2\&.15 or later) or
57 generates a few temporary files that
59 uses\&. These files are deleted at the end of execution\&.

120 The figure is divided into a number of regions\&. There are titles on the top that show important statistical information about the configuration and from this execution of
121 \fBamdump\fR\&. In the figure, the X axis is time, with 0 being the moment
123 was started\&. The Y axis is divided into 5 regions:
126 How many backups have not been started, how many are waiting on space in the holding disk and how many have been transferred successfully to tape\&.
129 Percentage of allowed network bandwidth in use\&.
132 The higher line depicts space allocated on the holding disk to backups in progress and completed backups waiting to be written to tape\&. The lower line depicts the fraction of the holding disk containing completed backups waiting to be written to tape including the file currently being written to tape\&. The scale is percentage of the holding disk\&.
138 Percentage of active dumpers\&.
140 The idle period at the left of the graph is time
142 is asking the machines how much data they are going to dump\&. This process can take a while if hosts are down or it takes them a long time to generate estimates\&.
145 Reports lines it does not recognize, mainly error cases but some are legitimate lines the program needs to be taught about\&.
