| class | DriveStats |
| Collects data about drive usage on the host. More... | |
| class | MemoryStats |
| Collects data about memory usage. More... | |
| class | NetworkStats |
| Collects data about network traffic on the computer. More... | |
| class | ProcessorStats |
| Collects data about processor usage. More... | |
| class | StatsProvider |
| Helper class which provides base for all stats providers. More... | |
| class | SystemStats |
| Collects various data about current system. More... | |
This class collects all data about system utilization. Most of the data are read from the files in /proc directory. Kernel 2.5.70 or newer is required for all features to work. On older kernels some data may not be available.
| lm::LoadMonitor::LoadMonitor | ( | void | ) |
Ctor.
| lm::LoadMonitor::~LoadMonitor | ( | void | ) |
Dtor.
| lm::LoadMonitor::LoadMonitor | ( | const LoadMonitor & | ) | [inline, private] |
Prevent copying of the monitor.
| HardwareDescription lm::LoadMonitor::GetHardwareDescription | ( | void | ) |
Get hardware description.
| unsigned long long lm::LoadMonitor::GetSampleTime | ( | void | ) | [static, private] |
Get current time in 100 ns intervals since Windows epoch.
This method uses clock_gettime function as a primary source of the time information. This function is available only on newer kernels (2.6) with sufficiently new libc (version 6 works fine).
| unsigned long long lm::LoadMonitor::GetTSC | ( | void | ) | const [inline, private] |
Get CPU TSC.
| bool lm::LoadMonitor::Initialize | ( | void | ) |
Initialize all counters.
| void lm::LoadMonitor::LogError | ( | const char * | message | ) | const [private] |
Log error message to the output.
| message | Message to write out. |
| void lm::LoadMonitor::LogInfo | ( | const char * | message | ) | const [private] |
Log info message to the output.
| message | Message to write out. |
| LoadMonitor& lm::LoadMonitor::operator= | ( | LoadMonitor & | ) | [inline, private] |
Assignment.
| LoadSample lm::LoadMonitor::TakeSample | ( | void | ) |
Take performance sample.
| bool lm::LoadMonitor::Terminate | ( | void | ) |
Free all resources and disconnect from WMI provider.
DriveStats lm::LoadMonitor::drive [private] |
Drive stats collector.
MemoryStats lm::LoadMonitor::memory [private] |
