SYNOPSIS
DESCRIPTION
The lustre2_client plugin provides Lustre metric information.
CONFIGURATION ATTRIBUTE SYNTAX
This plugin uses the sampler_base base class. This man page covers only the configuration attributes, or those with default values, specific to the this plugin; see ldms_sampler_base(7) for the attributes of the base class.
config name=<plugin_name> <SAMPLER_BASE_OPTIONS> osc=<CSV> mdc=<CSV> llite=<CSV> osc_path =<oscpath> mdc_path=<mdcpath>“llite_path=<llitepath>
Descriptions:
- name=<plugin_name>
This MUST be lustre2_client.
- <SAMPLER_BASE_OPTIONS>
Please see ldms_sampler_base(7) for sampler_base options.
- osc=<CSV>
CSV list of OSC’s.
- mdc=<CSV>
CSV list of MDC’s.
- llite=<CSV>
CSV list of LLITE’s.
- osc_path=<oscpath>
A user custom path to osc.
- mdc_path=<mdcpath>
A user custom path to osc.
- llite_path=<llitepath>
A user custom path to llite.
NOTES
For oscs,mdcs and llites: if not specified, NONE of the oscs/mdcs/llites will be added. If {oscs,mdcs,llites} is set to *, all of the available {oscs,mdcs,llites} at the time will be added.
The names that make up the list of oscs, mdcs and llites do not have to include the uid part. For example, ‘lustre-ffff8803245d4000’ is the actual file in /proc/fs/lustre/llite/, but you can just say llites=lustre to include this component into the set.
osc_path, mdc_path, llite_path are optional full path names of stats files if not in default location. The default locations are: /sys/kernel/debug/lustre/{osc, mdc, llite}, and /proc/fs/lustre/{osc, mdc, llite} depends on the Lustre version. Be aware that /sys/kernel/debug is only readable by privileged users.
BUGS
None known.
