question regarding disk monitoring

Hi Net-SNMP gurus, 

I would like to monitor the partition of my system using the DISMAN event MIB capabilities. Here what I like to achieve:

1- for some known file systems mounted at server boot time, I want to issue two kind of traps:
    (*) if file system is > X% full, a trap corresponding to a warning situation is sent.
    (*) if file system is > Y% full, a trap corresponding to an alarm situation is sent. 
Here X, and Y depends on the file systems. 

2- for the remaining file systems known when the Agent is started, a default policy applies: 
    (*) if file system is > 90% full, a trap corresponding to a warning situation is sent.
    (*) if file system is > 95% full, a trap corresponding to an alarm situation is sent.

I could implement 1) as follows: 

####
# monitor: /tmp
# policy : warning at 90%, alarm at 95%
disk /tmp 10%
monitor -i -r 60 -o dskPath.1 -o dskErrorMsg.1 "disk1WS" dskPercent.1 >= 90
monitor -i -r 60 -o dskPath.1 -o dskErrorMsg.1 "disk1AS" dskPercent.1 >= 95

# define all given FS similarly to /tmp
# ...

where "disk1WS" means "disk partition #1, warning set"
      "disk1AS" means "disk partition #1, alarm set" 

The trap receiver knows what to do depending on the trigger name. 

Now, my question is how I implement the "default policy". I could perhaps define something like:

# define default policy
# 
includeAllDisks 10
monitor -r 60 -o dskPath -o dskErrorMsg "diskDefaultWS" dskPercent >= 90
monitor -r 60 -o dskPath -o dskErrorMsg "diskDefaultAS" dskPercent >= 95

But the question is: what does happen if 1) and 2) are combined? Will the traps be generated as wanted for the file system defined in the disk sections and the default policy shall apply for the rest?

Or will the default policy overrides the specialized policies? If so, how can I achieve the wanted results? 


Thanks in advance,
Loic.
