Member Function Documentation

bool lm::LoadMonitor::NetworkStats::QueryData

(

HardwareDescription &

description

)

[virtual]

Collect data and store their descriptions.

This will parse /proc/dev/net file and extract name of each interface mentioned in the file.

Parameters:

description

Structure which will receive data collected by this provider.

Returns:

true on success, false otherwise.

Implements lm::LoadMonitor::StatsProvider.

bool lm::LoadMonitor::NetworkStats::QueryData

(

LoadSample &

sample

)

[virtual]

Collect data and store them in the sample.

This methods read /proc/net/dev file and extracts data from the "read bytes" and "write bytes" columns. If at least one sample has been taken prior call, statistics for the time between two samples is calculated. Otherwise result is set to all zeroes for all interfaces.

Parameters:

sample

Structure which will receive data collected by this provider.

Returns:

true on success, false otherwise.

Implements lm::LoadMonitor::StatsProvider.
