=head1 NAME
acpi_sys_batt_ Munin plugin to monitor the (note|net)book battery states through sysfs
=head1 APPLICABLE SYSTEMS
Notebooks and netbooks with avialable /sys/class/power_supply
=head1 CONFIGURATION
Configured change the name of symbolic link
acpi_sys_batt_X_capacity - chart of Charge full by design, Charge full and Charge now
acpi_sys_batt_X_current - chart of battery current
acpi_sys_batt_X_percents - percentage chart of Current/design voltage, Full/current capacity, Design/full capacity
acpi_sys_batt_X_voltage - chart of Design min voltage and Current voltage
Where X is the number of batteries from /sys/class/power_supply/BATX
=head1 INTERPRETATION
The plugin shows:
Charge full by design
Charge full
Charge now
Battery current
Percentage Current/design voltage
Percentage Full/current capacity
Percentage Design/full capacity
Design min voltage
Current voltage
