How accurate is the Hitachi-DF-RAID-LAN-MIB?  (I have version 22.0 20130821.)

 

I just incorporated it in our monitoring system and was surprised to see that the volume which holds the database files of a number of our Oracle databases displayed no activity.  To make sure I didn't mis-configure the monitoring system, I requested the same values with snmpwalk:

 

# snmpwalk -Os -v 1 -c xxx 10.32.2.212 .1.3.6.1.4.1.116.5.11.1.2.3.1.1.5.1306

dfWriteCommandNumber.1306 = INTEGER: 0

# snmpwalk -Os -v 1 -c xxx 10.32.2.212 .1.3.6.1.4.1.116.5.11.1.2.3.1.1.1.1306

dfLun.1306 = INTEGER: 1306

# snmpwalk -Os -v 1 -c xxx 10.32.2.212 .1.3.6.1.4.1.116.5.11.1.2.3.1.1.2.1306

dfReadCommandNumber.1306 = INTEGER: 0

# snmpwalk -Os -v 1 -c xxx 10.32.2.212 .1.3.6.1.4.1.116.5.11.1.2.3.1.1.3.1306

dfReadHitNumber.1306 = INTEGER: 0

# snmpwalk -Os -v 1 -c xxx 10.32.2.212 .1.3.6.1.4.1.116.5.11.1.2.3.1.1.4.1306

# snmpwalk -Os -v 1 -c xxx 10.32.2.212 .1.3.6.1.4.1.116.5.11.1.2.7.1.1.2.1306

dfInternalReadCommandNumber.1306 = INTEGER: 0

# snmpwalk -Os -v 1 -c xxx 10.32.2.212 .1.3.6.1.4.1.116.5.11.1.2.7.1.1.3.1306

# snmpwalk -Os -v 1 -c xxx 10.32.2.212 .1.3.6.1.4.1.116.5.11.1.2.7.1.1.4.1306

dfInternalReadHitRate.1306 = INTEGER: 0

# snmpwalk -Os -v 1 -c xxx 10.32.2.212 .1.3.6.1.4.1.116.5.11.1.2.7.1.1.5.1306

dfInternalWriteHitNumber.1306 = INTEGER: 0

# snmpwalk -Os -v 1 -c xxx 10.32.2.212 .1.3.6.1.4.1.116.5.11.1.2.7.1.1.7.1306

dfInternalWriteHitRate.1306 = INTEGER: 0

 

Yet when I monitor the device with HSNM2, there is plenty activity:

8    20/01/2016 11:44    115

9    20/01/2016 11:45    91

 

Do I misunderstand something?

 

Kind regards,
