+LDMS is "a low-overhead, low-latency framework for collecting, transferring, and storing metric data on a large distributed computer system" 
+and is packaged alongside [ovis-hpc](https://github.com/ovis-hpc/ovis). While there are complex aggregator setups we could run,
+for this simple metric we simply run (on each separate pod/node). The following variables are supported:
 
-Sysstat is stored as a general metrics analyzer, as it provides several different metric types; It generally provides utils to monitor system performance and usage, including:
+|Name | Description | Type | Default |
+|-----|-------------|------|------|

+| workdir | The working directory for the command |  string | /opt |
+| completions | Number of times to run metric | int32 | unset (runs for lifetime of application or indefinitely) |
+| rate | Seconds to pause between measurements | int32 | 10 |
+
+
+The following is the default command:
 
-- *iostat* reports CPU statistics and input/output statistics for block devices and partitions.
-- *mpstat* reports individual or combined processor related statistics.
-- *pidstat* reports statistics for Linux tasks (processes) : I/O, CPU, memory, etc.
-- *tapestat* reports statistics for tape drives connected to the system.
-- *cifsiostat* reports CIFS statistics.
