27 generates each run (e.g.
28 \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.
32 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.
35 is a shell script that executes an
38 (\fIamplot.awk\fR) to scan the
40 output file. It then executes a
43 (\fIamplot.g\fR) to generate the graph. The
45 program is written in an enhanced version of awk, such as GNU awk
47 version 2.15 or later) or
52 generates a few temporary files that
54 uses. These files are deleted at the end of execution.

117 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
118 \fBamdump\fR. In the figure, the X axis is time, with 0 being the moment
120 was started. The Y axis is divided into 5 regions:
123 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.
126 Percentage of allowed network bandwidth in use.
129 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.
135 Percentage of active dumpers.
137 The idle period at the left of the graph is time
139 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.
