[Observium] How to get the same number of graphs on both Windows and Linux machines?

I have a number of Windows and Linux machines, which communicate with Observium server. Linux machines report way more information than Windows. Is it possible to get more data from Windows machines?

The following data I get from Windows machines (System tab for example):

Running Processes Users Logged In Memory Pool Usage Processors Filesystem Usage Device Uptime

The following data I get from Linux machines (System tab again):

Running Processes Users Logged In Memory Pool Usage Processors Filesystem Usage Context Switches Detailed Processors System Interrupts System I/O Activity Load Averages Detailed Memory Swap I/O Activity Device Uptime

I use NET-SNMP on Linux machines and NuDesign SNMPv3 Master Agent Service on Windows machines.
