-Synopsis
-
-amplot [-b ] [-c ] [-e ] [-g ] [-l ] [-p ] [ -t T ] amdump_files
-
-DESCRIPTION
-
-Amplot reads an amdump output file that Amanda generates each run (e.g.
-amdump.1) 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. Amplot also prints out amdump 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.
-Amplot is a shell script that executes an awk program (amplot.awk) to scan the
-amdump output file. It then executes a gnuplot program (amplot.g) to generate
-the graph. The awk program is written in an enhanced version of awk, such as
-GNU awk (gawk version 2.15 or later) or nawk.
-During execution, amplot generates a few temporary files that gnuplot uses.
-These files are deleted at the end of execution.
-See the amanda(8) man page for more details about Amanda.
-
-OPTIONS
-
-
-
- -b
- Generate b/w postscript file (need -p).
-
- -c
- Compress amdump_files after plotting.
-
- -e
- Extend the X (time) axis if needed.
-
- -g
- Direct gnuplot output directly to the X11 display (default).
-
- -p
- Direct postscript output to file YYYYMMDD.ps (opposite of -g).
-
- -l
- Generate landscape oriented output (needs -p).
-
- -tT
- Set the right edge of the plot to be T hours.
-
-The amdump_files may be in various compressed formats (compress, gzip, pact,
-compact).
-
-INTERPRETATION
-
-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 amdump. In the figure, the X axis is time, with 0 being the
-moment amdump was started. The Y axis is divided into 5 regions:
-QUEUES: 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.
-%BANDWIDTH: Percentage of allowed network bandwidth in use.
-HOLDING DISK: 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.
-TAPE: Tape drive usage.
-%DUMPERS: Percentage of active dumpers.
-The idle period at the left of the graph is time amdump 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.

-BUGS
-
-Reports lines it does not recognize, mainly error cases but some are legitimate
-lines the program needs to be taught about.
