.SH "DESCRIPTION"
.PP
\fBAmplot\fR
reads an
\fBamdump\fR
output file that Amanda generates each run (e\&.g\&.
\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\&.
\fBAmplot\fR
also prints out
\fBamdump\fR
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\&.
.PP
\fBAmplot\fR
is a shell script that executes an
\fBawk\fR
program
(\fIamplot\&.awk\fR) to scan the
\fBamdump\fR
output file\&. It then executes a
\fBgnuplot\fR
program
(\fIamplot\&.g\fR) to generate the graph\&. The
\fBawk\fR
program is written in an enhanced version of awk, such as GNU awk (\fBgawk\fR(1)
version 2\&.15 or later) or
\fBnawk\fR(1)\&.
.PP
During execution,
\fBamplot\fR
generates a few temporary files that
\fBgnuplot\fR
uses\&. These files are deleted at the end of execution\&.
.PP
See the
\fBamanda\fR(8)
man page for more details about Amanda\&.
.SH "OPTIONS"
.PP
\fB\-b\fR
.RS 4
Generate b/w postscript file (need
\fB\-p\fR)\&.
.RE
.PP
\fB\-c\fR
.RS 4
Compress
\fIamdump_files\fR
after plotting\&.
.RE
.PP
\fB\-e\fR
.RS 4
Extend the X (time) axis if needed\&.
.RE
.PP
\fB\-g\fR
.RS 4
Direct
\fIgnuplot\fR
output directly to the X11 display (default)\&.
.RE
.PP
\fB\-p\fR
.RS 4
Direct postscript output to file
\fIYYYYMMDD\fR\fI\&.ps\fR
(opposite of
\fB\-g\fR)\&.
.RE
.PP
\fB\-l\fR
.RS 4
Generate landscape oriented output (needs
\fB\-p\fR)\&.
.RE
.PP
\fB\-t \fR\fIT\fR
.RS 4
Set the right edge of the plot to be
\fIT\fR
hours\&.
.RE
.PP
The
\fIamdump_files\fR
may be in various compressed formats (\fIcompress\fR,
\fBgzip\fR,
\fBpact\fR,
\fBcompact\fR)\&.
.SH "INTERPRETATION"
.PP
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
\fBamdump\fR\&. In the figure, the X axis is time, with 0 being the moment
\fBamdump\fR
was started\&. The Y axis is divided into 5 regions:
.PP
\fIQUEUES:\fR
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\&.
.PP
\fI%BANDWIDTH:\fR
Percentage of allowed network bandwidth in use\&.
.PP
\fIHOLDING DISK:\fR
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\&.
.PP
\fITAPE:\fR
Tape drive usage\&.
.PP
\fI%DUMPERS:\fR
Percentage of active dumpers\&.
.PP
The idle period at the left of the graph is time
\fBamdump\fR
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\&.
.SH "BUGS"
.PP
Reports lines it does not recognize, mainly error cases but some are legitimate lines the program needs to be taught about\&.
