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 flush‐ ing 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 sta‐ tistics 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 nor‐ mal. -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.
