View source for LDMS 3.x Plugins

You can list the stores and samplers and usage hints for your LDMS 3.4 installation with (typically)

  /usr/bin/ldms_list_plugins.sh

This will list the compiled and installed plugins and their options for use in the LDMS configuration language.
This may include experimental plugins. Generally, production plugins will have a man page, for example to understand the
meminfo plugin, try

  man Plugin_meminfo

Unfortunately, the man pages may not be installed on your system or they may not yet be complete.
If anything in the table below provokes a question, please send it to the ovis-help mailing list described elsewhere.

Migration note: LDMS v4 will introduce ldms-plugins.sh with better functionality.
