NAME 

Plugin_store_slurm - man page for the LDMSD store_slurm plugin

SYNOPSIS 

Within ldmsd_controller or a configuration file: load name=store_slurm

config name=store_slurm path=STORE_ROOT_PATH [ verbosity=(0|1|2) ]

strgp_add name=STRGP_NAME plugin=store_slurm container=CONTAINER schema=mt-slurm

strgp_prdcr_add name=STRGP_NAME regex=PRDCR_REGEX

DESCRIPTION 

store_slurm is an LDMSD storage plugin that stores job data from slurm_sampler specifically, and must not be used with other data.

PLUGIN CONFIG OPTIONS 

name=store_slurm: This MUST be store_slurm (the name of the plugin).
path=STORE_ROOT_PATH: The path to the root of the store. SOS container for each schema specified by the storage policy (strgp) will be placed in the STORE_ROOT_PATH directory.

verbosity=(0|1|2)

0
(default) for SUMMARY verbosity level. The storage plugin only stores single entry for each job.

1
for RANK verbosity level. The storage plugin stores job data entry per each rank (process) in the job.

2
for TIME (the most verbosed) verbosity level. The storage plugin stores job data entries every time the slurm_sampler set is updated. In this verbosity level, we would have a lot of job entries that are the same in everything except for the timestamp.

An LDMSD storage plugin is like a storage driver that provides only storing mechanism. A storage policy (strgp) is a glue binding data sets from various producers to a container of a storage plugin.

strgp_add command defines a new storage policy, identified by name. The plugin attribute tells the storage policy which storage plugin to work with. The schema attribute identifies LDMS schema the data set of which is consumed by the storage policy. The container attribute identifies a container inside the storage plugin that will store data.

The schema for store_slurm is always mt-slurm as slurm_sampler restricts “mt-slurm” as its schema name.

strgp_prdcr_add is a command to specify producers that feed data to the storage policy.

BUGS 

No known bugs.
