![]() If you only have a single core, you should move up to a better machine or virtual host. A system can operate trouble-free with a 60% load for example, but at 70% it becomes a lot slower than an increase of 10 percentage points would suggest.įor your numbers from above (0.86, 1.17, 1.20): They are just barely enough if you have 2 cpu cores available. ![]() Normally you should make sure that a cpu is not experiencing loads above 70% as collisions of processes increase exponentially. On a single-core-processor a cpu load of 0.86 means that the system is experiencing an 86% load (too much, see below). CPU Usage Even though CPU load and CPU usage sound similar, they are not interchangeable. In this article, we’ll look at how to interpret CPU metrics and display them in a human-readable format. cat /proc/cpuinfo (Image credit: Tom's Hardware) This command will produce a. On a 4-core-processor a cpu load of 1.10 means that the system has a 27.5 % overall load. Unlike disk and memory, monitoring the CPU usage on a Linux system isn’t as straightforward. Use the cat command to display the data held in /proc/cpuinfo. n, -null null run - Don’t start any counters. A, -no-aggr Do not aggregate counts across all monitored CPUs. The -a option is still necessary to activate system-wide monitoring. In per-thread mode, this option is ignored. My understanding of /proc/stat is very limited, but this one-liner works good enough for me: cat <(grep cpu /proc/stat) <(sleep 1 & grep cpu /proc/stat). driver-defined statistics available via ethtool. Ranges of CPUs are specified with -: 0-2. There are three main sources of interface statistics in Linux: standard interface statistics based on struct rtnllinkstats64 protocol-specific statistics and. On a 12-core-processor a cpu load of 6 means that the system has a 50% overall load. This document is a guide to Linux network interface statistics. So a cpu load larger 1 is not an issue on systems with multiple cores. Here's some sample output for my current shell you'll need to look. If you do ' man proc ' you can see what information is stored, but for per-thread resource consumption you'll want /proc/PID/task/TID/stat, where PID is the process ID and TID is the thread ID. A cpu load of 4 means that 4 cpus would be needed to instantly process all requests. The standard interface to per-process kernel statistics is the /proc filesystem. The cpu usage gives you the load of the total of all cpu cores where 1 is 100% of one core.
