LDMS sampler

SYNOPSIS

Within ldmsd_controller or a configuration file:
config name=hweventpapi [ <attr>=<value> ]

DESCRIPTION

With LDMS (Lightweight Distributed Metric Service), plugins for the ldmsd (ldms daemon) are configured via ldmsd_controller or a configuration file. The hweventpapi plugin provides energy sampling using RAPL via the PAPI interface for sandybridge.

WARNING: This sampler is unsupported.

CONFIGURATION ATTRIBUTE SYNTAX

The hweventpapi 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> [schema=<sname>]
configuration line
name=<plugin_name>

This MUST be hweventpapi.
schema=<schema>

Optional schema name. It is intended that the same sampler on different nodes with different metrics have a different schema. If not specified, will default to `hweventpapi`.
metafile=<PATH>

The metafile defines what to collect with undocumented “attribute=value” syntax. The metafile is watched for changes and automatically reloaded.

BUGS

This man page is incomplete.

NOTES

  • This sampler is unsupported.
