Baleia is a command-line tool (and complimentary Telegram bot) to retrieve data about your Raspberry Pi, with implementations in C++11 or Go. Although made to target the RPi, it should run (although lacking vcgencmd-originated data) on any system running GNU/Linux.
Both C++11 and Go source codes should produce the exact same logs, with the main difference being the specification format used by the -f, --fmt flag, with very similar performance. The Go binaries in the releases page are statically linked so they'll run even if Go is not installed on your destination system.
Usage: ./baleia [-c, --cpu] [-f, --file-info] [-u, --user] [-a, --all] [-d, --discard] [-C, --cfg] [--fmt <format-string>]
-h, --help Show this message and exit.
-c, --cpu Save CPU frequency, temperature and scaling governor.
-u, --user Save user and OS data.
-F, --file-info Save filename and Baleia version.
-a, --all Save all available data.
-d, --discard Print to stdout without saving to a file.
-t, --toml Saves the output in TOML format.
--fmt <fmt-str> Dictate output's filename following the `strftime` format specification.Easily parsable format, ready for use with TOML or rxi/ini. This format is used when the --cfg flag is set.
An example follows:
./baleia -at

git clone https://github.com/vrmiguel/baleia.git
cd baleia/baleia-cpp
qmake
makeTo build the Go version (through cross-compilation):
git clone https://github.com/vrmiguel/baleia.git
cd baleia/baleia-go
export GOOS=linux
export GOARCH=arm
go build -o baleia-go-arm main.goBinaries can be found at the releases page.
If you wish to use this programmatically, you can use the librpidata.cpp/.h files, which provide a RPIData namespace with the methods you'd want to use, when on C++, or the rpidata module when using Go.
