Issue:

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} 
2017-08-02 11:54:37,280 [CommandPoolExecutor_0_213] ERROR Error while processing 'symstat -type MEMIO -sid 000195700853 -i 90 overwrite -c 1 -out xml' 
com.bt.probes.exception.ExtractorException: Error extracting data from file C:\Program Files (x86)\Nimsoft\probes\storage\vmax\data\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

 

Environment:
UIM: 8.51 UMP: 8.51 OS: Windows 2008 probe: vmax 2.04T1
Cause:

The "overwrite" flag may be an invalid flag for some versions of the EMC symstat command.

Resolution:

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". 

Additional Information:

The metric QOS_STORAGE_SYMM_MEM_WP_MAX_PERCENT is only available in releases 1.40 and later of the UIM vmax probe.
