Monitoring of multiple drives

Hi,

I'm a OpManager newbie, and currently in an evaluation process. Very impressed so far. One question though; how do I specify monitoring of multiple disk drives on a single server? I found this topic: http://forums.manageengine.com/forumHome.do?forumGroupId=49000000002007&forumTopicId=49000002634231, and the respond

1 . Host Resource Graphs - Uses SNMP to query the Data.
2. Windows Performance Counters - Uses WMI
3. Linux Performance Counters - Uses Telnet/SSH
4. Solaris Performance Counters - Uses Telnet/SSH

Select Configure -> Graphs from the server snapshot page on the right side of the page to select and associate any one of these graphs to the server. The WMI, Telnet or SSH graphs require login details of the server to collect the data.

The trouble is; I can't see any configure -> graphs on my snapshot page. The only configurable elements are

URL Monitor
Device Properties
Monitoring
Event Log Rules
Device Type
Dependency
Passwords

I'm probably being thick here - but how do I monitor multiple disk drives (e,f,g etc)?

Thanks,
