I've never tried to "monitor" a network device with SysAid.
In order to get MRTG Graphs and thresholds I'd rather recommend CACTI or NAGIOS than SysAid (sorry folks!).
I've never made to convince SysAid to get a correct inventory of our Dell Switches nor setting up monitoring.
Cacti also monitors my servers ambient temparature sensore (which saves money for a climatic surveylance hardware) and everything via SNMP.
So I will stick with Cacti until SysAid improves on that point.
