VMAX probe Metric QOS_STORAGE_SYMM_MEM_WP_MAX_PERCENT is returning 0 values consistently. This may be normal. However, we found the following error in the vmax.log file:
2017-08-02 11:54:37,280 [CommandPoolExecutor_0_213] INFO PERF: DONE: Command.ProcessResult: symstat -type MEMIO -sid 000195700853 -i 90 overwrite -c 1 -out xml {Seconds=0.000} {output=localhost.000195700853.memiostats.xml}

We ran the command manually.
symstat -type MEMIO -sid 000195700853 -i 90 overwrite -c 1 -out xml {Seconds=0.000} {output=localhost.000195700853.memiostats.xml}
This returned an error:
'overwrite': Illegal option
The "overwrite" flag may be an invalid flag for some versions of the EMC symstat command.
Open the "Raw Configure" for the vmax probe.
Under the <setup> section, look for: "stats interval".
Change the value to "90" instead of "90 overwrite".
The metric QOS_STORAGE_SYMM_MEM_WP_MAX_PERCENT is only available in releases 1.40 and later of the UIM vmax probe.
