Detailed Description

A timer that periodically checks CPU load and logs a warning if it exceeds a configured threshold.

This class is intended for monitoring system performance during runtime. It uses OpenMRN's Timer infrastructure and samples CPU load every 33 ms. When the 1-second averaged CPU load exceeds the configured threshold, it logs a warning message.

The actual CPU load is retrieved from CpuLoad::instance().

Member Function Documentation

timeout()

long long CpuCheckTimer::timeout ( )

inlineoverride

Called by the OpenMRN timer scheduler at regular intervals.

This method checks the current CPU load. If it exceeds the configured threshold, a warning is logged.

Returns

Time in nanoseconds until the next timer event (33 ms).
