You can list the stores and samplers and usage hints for your LDMS 3.4 installation with (typically)
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
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.
Production Sampler Plugins
Below is a summary of the plugins that can be considered production quality in release 3.4.4 for commodity Linux environments.
|metric set content
|memory and other statistics from LDMSD itself
|memory error checking from /sys/devices/system/edac metrics
|Currently running job id and user (requires loose cooperation from queuing system, e.g. slurm)
|/proc/sys/lnet/stats metrics, particularly memory
|Lustre client metrics
|interrupt counters (very large datasets on many-core machines)
|/proc/net tcp interface device counters (excludes rdma traffic/errors)
|nfs v3 client statistics (calls, bytes)
|/proc/stat counters (includes cpu tick)
|infiniband counters and rates (includes rdma traffic/errors)
Production Store Plugins
|requires the size of metric sets of a given name (schema) be identical across all nodes.
|narrow CSV file per metric with timestamp and source columns. Tolerates conflicting schema definitions.
|feeds all metrics to single AMQP broker via librabbitmq 0.8. (multiple routing keys)
|feeds all metrics to single AMQP broker via librabbitmq 0.8. (single routing key)
Below is a summary of the plugins that can be considered production quality in release 3.4.4 for CLE6
|Cray XC aries network counters
|wide variety of Cray XE/XC metrics
|kernel-space sampler for network data
These also work on appropriate platforms
|AMD CPU event counters
|floating point transmission test sets (testing)
|generates synthetic waveform data sets (testing)
|high frequency clock
|Process perf event counters
|Power API 1
|infiniband switch port data
|Scalable Object Store storage prototype
All other plugins should be considered unsupported.
