Main indicators for assessing CPU load in Linux:

Load Average — the average number of processes waiting to run over the last 1, 5, and 15 minutes. You can view this with the command uptime or cat /proc/loadavg.
CPU Usage — the percentage of CPU utilization, including user time, system time, and idle time. The commands top or htop display this data.
Number of processes in "R" (Running) and "D" (Uninterruptible sleep) states — helps understand how many processes are actively loading the CPU or waiting for resources.
Information from /proc/stat — contains detailed statistics on CPU operational time in various modes.

These indicators together help understand how loaded the processor is and whether there are bottlenecks in the system.
