Customize watch and make calculation with OID

Customize watch and make calculation with OID

Hi there, I´m evaluating OpManager software and I have a few doubts:
1: Can I customize the watch in a device snapshot page with another monitor?
2: In a pre existing device template or in a new one, How can I create a new monitor that allow me make same calculation with the OID?
3: How can I change the OID of a pre existing monitor template?
4: Where are the templates files (in wich folder)? I Can edit them direct?



 
Exemplo for item 2: (.1.3.6.1.2.1.25.2.3.1.4.1*(.1.3.6.1.2.1.25.2.3.1.5.1-.1.3.6.1.2.1.25.2.3.1.6.1))/(1073741824)
 
Sorry about my English.
