leanux

Leanux is a C++ API to Linux performance and configuration data and includes a few tools utilizing this API.

The C++ API eases access to system configuration data provided by the /sys pseudo filesystem, so including CPUs, block devices, network devices and so on. Additionally, the C++ API exposes performance data from the /proc pseudo fillesystem.

The (C++) binaries produced by this repository are

component	purpose
libleanux.so	Shared library backing the leanux C++ API, required by the below tools
lard	daemon that logs performance and base configuration data to a SQLite database file
lmon	ncurses (tty) based performance viewer, both real-time and browsing historic data from the lard daemon, with colors, dynamic screen resizing
lrep	generates html reports on lard data
lsys	command-line tool to retrieve sysfs info for administrative use
lblk	command-line tool to retrieve block device and filesystem info for administrative use
labbix	Zabbix disk discovery and disk performance statistics for GNU/Linux

See leanux on github pages for more documentation. If you are on github pages now, you can view the doxygen code documentation as here, and the links in the above table will link to pdf documents.

Building from source

Builds should work on any Linux host that satisfies

The build depends on

• A C++ toolchain with c++11 capability
• sqlite3 development headers
• ncurses development headers

Download a release

$ tar zxvf leanux-1.0.5-snapshot.tar.gz
$ cd leanux-1.0.5-snapshot
