What Is Load Average? Uncovering the Truth Behind System Load Metrics

Load Average measures the average number of runnable and uninterruptible processes over 1, 5, and 15‑minute windows, differs from CPU usage, and can be misinterpreted—this article explains its kernel calculation, how to assess overload, troubleshoot CPU, I/O, or process‑count issues, and handle container‑specific distortions with cgroup v2 and LXCFS.

Understanding Linux Load Average: Calculation, Exposure, and Relation to CPU Usage

Linux load average, a key performance metric, is computed by periodically aggregating per‑CPU runnable and uninterruptible task counts into a global instantaneous load, then applying an exponential weighted moving average to produce 1‑, 5‑, and 15‑minute averages, which are exposed to user space via the /proc/loadavg pseudo‑file.
