The ability to perform mathematical operations and comparisons between multiple OIDs is not possible in SNMPMon. However, it's a logged feature request and I added your use case to the database.

On OID .1.3.6.1.2.1.25.2.3.1.5.$instance you will get the total amount of space for the partition. I would like to monitor available space on several servers for our customers and then get the return value by subtract the available amount of space from the total amount of space available. If the amount of available space is below 100 Mb i would like to receive an alert. Is this possible without having to create a large amount of custom services based on used space?

(The KB article shown refers to that MIB) Win2K uses the Host MIB by default. It is quite a task to figure out what is what with that. The OID for MIBII Host storage is: .1.3.6.1.2.1.25.2.3.1.6.$instance or .iso.org.dod.internet.mgmt.mib-2.host.hrStorage.hrStorageTable.hrStorageEntr y.hrStorageUsed This is in "Storage allocation units". To get the true byte value for this you must multiply the above returned value by the size of the storage allocation units .1.3.6.1.2.1.25.2.3.1.4.$instance or .iso.org.dod.internet.mgmt.mib-2.host.hrStorage.hrStorageTable.hrStorageEntr y.hrStorageAllocationUnits.$instance An example: Say you want to notify if your disk drops below 100MB(100000000) of space and your Storage allocation unit size is 4096. You will need to divide 100000000 by 4096. You then monitor hrStorageUsed and use the value you just figured out to create your SNMP monitor. I know that was a tad confusing. I hope I helped.
