I wondered how quickly my laptop battery deteriorates over time. This little tool creates a sqlite database and records battery values from /sys/class/power_supply.
For convencience a simple dump method is included.
go get github.com/krysopath/watchmon
go install github.com/krysopath/watchmon
Get the binary and build it.
crontab -e
Open the crontab editor
*/N * * * * $HOME/go/bin/watchmon | logger
Adapt the
Nto set how many minutes between executions should pass. Also check the PATH.
Lastly:
watchmon -dbcreate
Creates the sqlite file
watchmon -dump
To enable <TAB><TAB> madness, run bash with bash-completions and source:
. watchmon-completion
