NAME

       battery-stats-collector - Collect statistics about battery charge

SYNOPSIS

       battery-stats-collector [option] ...

DESCRIPTION

       Does exactly as it says on the tin - it will collect information from the APM subsystem and write it to a
       log file.

       Normally battery-stats-collector will be invoked by the system startup scripts.

OPTIONS

       battery-stats follow the usual GNU command line syntax, with long options starting with two dashes (`-').

       -o FILE, --output FILE
              Append statistics to the given file. The default filename is /var/log/battery-stats

       -i SECS, --interval=SECS
              Sampling intervals in seconds. If not specified, stats will be collected every 30 seconds.

       -F COUNT, --flush=COUNT
              Flushes  data  to the log file every COUNT samples. A value of zero turns off flushing altogether.
              If left unspecified, battery-stats-collector will assume a value of 1, i.e. flush at every  write.
              Setting  the  value  too  low  will  tend  to keep the disk spinning (and use battery needlessly).
              Setting the value too high will loose statistics in case of an improper shutdown.
              Note that since battery-stats-collector uses the standard Ansi  C  library,  data  will  still  be
              flushed periodically (regardless of this setting) once the buffer fills up. The size of the buffer
              is platform dependent, but 4Kb and 8Kb seem pretty normal.

       -b NUM, --battery-num=NUM
              Read information about battery number NUM. (In case you have multiple batteries installed).

       -1, --once
              Only collect a single sample and exit. The default is to loop continiously.

       -I, --ignore-missing-battery
              Keeps quiet about missing batteries. This stops the warnings on stderr/syslog that would otherwise
              occur when the battery is missing.

       -s, --syslog
              Log  error  messages  to  syslog, rather than stderr. Note that messages regarding invalid command
              line parameters will still go to stderr.

       -V, --version
              Show version of battery-stats-collector and exit.

       -h, --help
              Show summary of options and exit.

FILES

       /var/log/battery-stats
              Default file for writing battery charge samples to.
