battery-stats-collector - Collect statistics about battery charge
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.
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
- -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
- -I, --ignore-missing-battery
- Keeps quiet about missing batteries. This stops the
warnings on stderr/syslog that would otherwise occur when the battery is
- -s, --syslog
- Log error messages to syslog, rather than stderr. Note that
messages regarding invalid command line parameters will still go to
- -V, --version
- Show version of battery-stats-collector and exit.
- -h, --help
- Show summary of options and exit.
- Default file for writing battery charge samples to.
