Use case for EVRICA - Embedded system data measurement tool - (2)

Easy monitoring with EVRICA - CPU overload at a glance!

EVRICA is a data monitoring tool that enables fast, real-time visualization of variables and parameters in memory that were previously acquired by printf or other methods.
EVRICA can continuously acquire data in memory, such as motor rotation control parameters, without stopping the user system and without programme modification, and display them as waveforms or numerical values.

Previous methods for data measurement
Monitor system performance by executing commands (such as the top command) in the console, focusing only on the numerical output.

Conventional methods had limitations; the "top" command risks missing data spikes due to lack of history, and CPU monitoring commands fail to provide real-time visualization.

The EVRICA Method: A Novel Approach to Data Measurement
EVRICA's real-time graphing allows for immediate identification of periods of high CPU load.

EVRICA achieves real-time CPU usage monitoring by having a user-provided daemon write usage data directly to memory.
