Detailed Description

Nerve Gear data source implementation.

Available data, value and IDs:

• System Data
  • Data UID: NERvGear::DATA::ID_SYS
  • Data Values: NERvGear::DATA::SYS::VALUE
• Core Data
  • Data UID: NERvGear::DATA::ID_CORE
  • Data Values: NERvGear::DATA::CORE::VALUE
• CPU Usage Data
  • Data UID: NERvGear::DATA::ID_CPU
  • Data Values: Each value represents a CPU core, use IData::GetValueCount() to retrieve CPU core amount.
• RAM Usage Data
  • Data UID: NERvGear::DATA::ID_RAM
  • Data Values: NERvGear::DATA::RAM::VALUE
• Hard Disk Usage Data
  • Data UID: NERvGear::DATA::ID_HDD
  • Data Values: NERvGear::DATA::HDD::VALUE
• Power Data
  • Data UID: NERvGear::DATA::ID_PWR
  • Data Values: NERvGear::DATA::PWR::VALUE
• Miscellaneous Data
  • Data UID: NERvGear::DATA::ID_MISC
  • Data Values: NERvGear::DATA::MISC::VALUE

All of the value types are fixed and indicated by the prefix of their IDs.
For example, ID NERvGear::DATA::SYS::STR_OS_NAME indicates that the value of 'OS Name' is a string, while NERvGear::DATA::CORE::I32_SERVICE_COMPONENT means the value of 'Component Service' is a 4-bytes integer.
