This repo provides a parsed representation of common Lustre statistics.
It is provided as a standalone binary that can be called to retrieve stats in the desired output (Currently either JSON | YAML).
A lustre_collector
musl binary is provided with the latest release. It can be downloaded and run
directly on an x86_64 linux machine.
# Will return stats in JSON format
lustre_collector
# Will return stats in YAML format
lustre_collector --format=yaml
