To obtain the current filesystem usage for any Compaq server, build a MIB
application in NetView (without the MLM) as follows (of course, make your own
changes as you see fit):

Select Tools->MIB Application Builder: SNMP...->select Add->enter the following
options in the data fields shown on the menu:

application ID = cpqFileSpace
application type = table
application title= Compaq filesystem utilization
Label          mib object id
FileSysName    ...cpqHoFileSysDesc
PercentUsed    ...cpqHoFileSysPercentSpaceUsed
Used Mbytes    ...cpqHoFileSysSpaceUsed
TotalMbytes    ...cpqHoFileSysSpaceTotal

where the full mib object id is :
.iso.org.dod.internet.private.enterprises.compaq.cpqHostOs.cpqHoComponent.cpqFilesys.cpqHoFileSysTable.cpqHoFileSysEntry.<mib

object id> from above table.

Incidentally the following labels and widths look nice:
FileSysName       11
PercentUsed          4
UsedMbytes         11
TotalMbytes          11

Menu Path = Monitor->System Activity->cpqFileSpace

Selection Rule = (isSNMPSupported)||(isSNMPProxied)



To automatically monitor the filesystem space on any Compaq server, create an
snmpCollection as follows:

Select Tools->Data Collection and Thresholds: SNMP...->select add and then enter
the following options:
walk the compaq mib down to cpqHoFileSysPercentSpaceUsed

enter for label = cpqFilePercentUsed

try these values:

collection mode = don't store, check thresholds
polling interval = 1h
store =no
threshold = >92
rearm <=  87 absolute
source = list of compaq servers
instances = all
trap number 58720263,  where this trap has been previously added under netview's
enterprise 1.3.6.1.4.1.2.6.3.  In this event customization for "event log
message",  use 'Host $A reports $4: $3

This looks complicated but when completed, it works as slick as the proverbial
baby's behind.
