Lustre
Overview
The Lustre® file system is an open-source, parallel file system that supports many requirements of leadership class HPC simulation environments.
This plugin monitors the Lustre file system using its entries in the proc filesystem.
Configuration
# Read metrics from local Lustre service on OST, MDS
[[inputs.lustre2]]
## An array of /proc globs to search for Lustre stats
## If not specified, the default will work on Lustre 2.5.x
##
# ost_procfiles = [
# "/proc/fs/lustre/obdfilter/*/stats",
# "/proc/fs/lustre/osd-ldiskfs/*/stats",
# "/proc/fs/lustre/obdfilter/*/job_stats",
# ]
# mds_procfiles = [
# "/proc/fs/lustre/mdt/*/md_stats",
# "/proc/fs/lustre/mdt/*/job_stats",
# ]
Troubleshooting
Check for the default or custom procfiles in the proc filesystem, and reference the [Lustre Monitoring and Statistics Guide](http://wiki.lustre.org/Lustre_Monitoring_and_Statistics_Guide. This plugin does not report all information from these files, only a limited set of items corresponding to the above metric fields.
