=head1 APPLICABLE SYSTEMS
|
|
|
|

=head1 INTERPRETATION
|
|
|
|
|
|
|
|
|
|
The plugin shows:
|
|
|
|
|
Design capacity -> avialable if avialable /proc/acpi/battery/BATx or /sys/class/power_supply/BATx
|
|
|
|
|
Last full capacity -> avialable if avialable /proc/acpi/battery/BATx or /sys/class/power_supply/BATx
|
|
|
|
|
Design capacity low -> avialable only if avialable /proc/acpi/battery/BATx
|
|
|
|
|
Design capacity warning -> avialable only if avialable /proc/acpi/battery/BATx
|
|
|
|
|
Capacity granularity 1 -> avialable only if avialable /proc/acpi/battery/BATx
|
|
|
|
|
Capacity granularity 2 -> avialable only if avialable /proc/acpi/battery/BATx
|
|
|
|
|
Remaining capacity -> avialable if avialable /proc/acpi/battery/BATx or /sys/class/power_supply/BATx
|
|
|
|
|
Present rate -> avialable if avialable /proc/acpi/battery/BATx or /sys/class/power_supply/BATx
|
|
|
|
|
Percentage Current/design voltage -> avialable if avialable /proc/acpi/battery/BATx or /sys/class/power_supply/BATx
|
|
|
|
|
Percentage Current/full capacity -> avialable if avialable /proc/acpi/battery/BATx or /sys/class/power_supply/BATx
|
|
|
|
|
Percentage Full/design capacity -> avialable if avialable /proc/acpi/battery/BATx or /sys/class/power_supply/BATx
|
|
|
|
|
Design voltage -> avialable if avialable /proc/acpi/battery/BATx or /sys/class/power_supply/BATx
|
|
|
|
|
Present voltage -> avialable if avialable /proc/acpi/battery/BATx or /sys/class/power_supply/BATx
