Use the following GET request to collect the Percentage CPU metric from a Virtual Machine GET /providers/microsoft. Unix & Linux Stack Exchange is a question and answer site for users of Linux, FreeBSD and other Unx-like operating systems. Currently available for linux, macOS and windows. This example shows how to retrieve the CPU usage for a Linux Virtual Machine using the Azure REST API.Ĭomplete reference documentation and additional samples for the REST API are available in the Azure Monitor REST reference. This module implements service that check RAM and CPU characteristics and decides according to passed. Once that is divided by the number of cores ( nproc -all), you will get the current CPU usage: top -bn2 | grep '%Cpu' | tail -1 | grep -P '(.|.Applies to: ✔️ Linux VMs ✔️ Flexible scale sets If you want to know the total CPU usage on your system every second, you can use the id attribute (IDLE) of the top output. The last column is labelled cpu and should be where we are interested in here. Complete reference documentation and additional samples for the REST API are available in the Azure Monitor REST reference. Using vmstat command The vmstat command reports virtual memory statistics about processes, memory, paging, block IO, traps, and CPU utilization. We can simply sum of all difference between two consecutive reads to get the time elapsed between these reads. This means we have to read the values from /proc/stat on a fixed interval and calculate the delta from these readings. The 45% usage you're seeing for your application is most likely the usage on one core of the CPU, which is why you can have the sum of the numbers in the %CPU column exceed 100%. This example shows how to retrieve the CPU usage for a Linux Virtual Machine using the Azure REST API. The CPU usage can be measured over an interval of time only.
