Understanding CPU time shortages isn't simple. Conventional metrics like CPU usage or Load Average may not suffice. Few realize the Linux kernel tracks task wait times for kernel resources. This talk delves into Linux kernel metrics unveiling CPU time shortages, essential for managing application latency.


Determining if a process lacks CPU time isn't straightforward. Traditional metrics like CPU usage or Load Average don't provide a clear answer.
Not many know that the Linux kernel precisely measures the time each task spends waiting for kernel resources to become available.
This talk explores how Linux kernel metrics reveal CPU time shortages, offering insights crucial for managing application latency.
