35 generates each run (e\&.g\&.
36 \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\&.
40 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\&.
43 is a shell script that executes an
46 (\fIamplot\&.awk\fR) to scan the
48 output file\&. It then executes a
51 (\fIamplot\&.g\fR) to generate the graph\&. The
53 program is written in an enhanced version of awk, such as GNU awk

125 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
126 \fBamdump\fR\&. In the figure, the X axis is time, with 0 being the moment
128 was started\&. The Y axis is divided into 5 regions:
131 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\&.
134 Percentage of allowed network bandwidth in use\&.
137 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\&.
143 Percentage of active dumpers\&.
145 The idle period at the left of the graph is time
147 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\&.
150 Reports lines it does not recognize, mainly error cases but some are legitimate lines the program needs to be taught about\&.
