linux-metrics is a Python package containing modules for getting OS metrics on systems running the Linux kernel. It is a pure python library with no external dependencies.
Basic stats for major subsystems are provided (Processor/CPU, Disk, Memory, Network).
- pip install linux-metrics
- Python 2.6+
- Linux 2.6+

You can run the included unit tests and verify all cases pass in your environment:
Note: you may need to adjust the configuration of the unit tests to match your environment. They are set by default to use:
DISK_DEVICE = 'sda1'
NETWORK_INTERFACE = 'eth0'
