amplot - visualize the behavior of Amanda 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(1) version 2.15 or later) or nawk(1). 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 (opposite of -g). -l Generate landscape oriented output (needs -p). -t T 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. SEE ALSO

amdump - back up all disks in an Amanda configuration SYNOPSIS
amdump [--no-taper] [--exact-match] [-o configoption...] config [host [disk...]...] DESCRIPTION
Amdump is the main interface to the Amanda backup process. It loads the specified configuration and attempts to back up every disk specified by the disklist(5). Amdump is normally run by cron. The command optionally takes a set of DLE specifications (see amanda-match(7)) to narrow the DLEs that will be dumped. All disks are dumped if no expressions are given. If a file named hold exists in the configuration directory, amdump will wait until it is removed before starting the backups. This allows scheduled backups to be delayed when circumstances warrant, for example, if the tape device is being used for some other purpose. While waiting, amdump checks for the hold file every minute. In some cases it is desirable to dump all Amanda clients to holding disk without writing anything to storage media. The --no-taper option instructs Amanda to not start the taper, and thus enter degraded mode immediately. See the amanda(8) man page for more details about Amanda. OPTIONS
host [disk]* Specify the host and disk on which the command will work -- see the description of DLE specifications in amanda-match(7). --exact-match The host and disk are parsed as exact values -o configoption See the "CONFIGURATION OVERRIDE" section in amanda(8). EXAMPLE
Here is a typical crontab entry. It runs amdump every weeknight at 1 a.m. as user bin: 0 1 * * 1-5 bin /usr/local/sbin/amdump daily Please see the crontab(5) or crontab(1) manual page for the correct crontab format for your system. MESSAGES
amdump: waiting for hold file to be removed The "hold" file exists and amdump is waiting for it to be removed before starting backups. amdump: amdump or amflush is already running, or you must run amcleanup Amdump detected another amdump or amflush running, or the remains of a previous incomplete amdump or amflush run. This run is terminated. If the problem is caused by the remains of a previous run, you must execute amcleanup(8) and then rerun amdump. EXIT CODE
The exit code of amdump is the ORed value of: 0 = success 1 = error 2 = a dle give strange message 4 = a dle failed 8 = Don't know the status of a dle (RESULT_MISSING in the report) 16 = tape error or no more tape SEE ALSO
