我们通过 “cat /proc/stat”命令可以查看其中的具体内容,其中cpu、cpu0、cpu1、cpu2、cpu3、cpu4这几行的的计数是用来计算cpu占用率的,每一行参数从前到后其含义如下: user: (32262891) 从系统启动开始累计到当前时刻,用户态的CPU时间(单位:jiffies),不包含 nice值为正进程。1jiffies=0.01秒 nice: (1024706)...
usage = (time - pretime)/monitor_time 就是在一次监控周期内,两次 cputime 统计值的差占监控时间的比例。 CPU 状态是否报警取决于结果和配置中预设的值的比较。 CheckMemoryUsage 检查内存使用情况的逻辑和 CPU 差不多。 如果没有进程 DAG 则检测 SystemMemoryUsage 否则就通过 pid 一个个获取单个进程的内存...

CheckCPUUsage 实际执行的是 GetSystemCPUUsage 或者 GetCPUUsage 方法。 核心逻辑无非就是通过代码执行命令行脚本/proc/stat。这个命令包含了系统内核中很多信息,就如 CPU 信息。比如,我在我的 WIN11 系统中的 WSL 中查看 /proc/stat 信息,出现下面的结果 : ...
system monitor linux System Monitor is a powerful tool for monitoring and managing various aspects of a Linux system. It allows users to view real-time information about system resources, such as CPU usage, memory usage, disk usage, network activity, and more....
CPU-MEM-monitor CPU-MEM-monitor is a simple script to monitor Linux CPU and memory usage over time and output a CSV report that can be easily analysed and plotted with e.g., Excel or OpenOffice Calc. More in details, this script allows to monitor per-thread CPU usage and memory usage ...
CPU usage has traditionally been the most common performance metric when monitoring Linux servers. You need to receive alerts when server CPUs are reaching their saturation point. The key statistic to watch is the percentage of time the CPU is in use. The raw CPU percentage doesn’t tell the...

The following example creates an alert for average CPU usage. In the Azure portal, click Resource Groups, select myResourceGroupMonitor, and then select myVM in the resource list. Click Alert rules on the VM blade, then click Add metric alert across the top of the alerts blade. Provide a...
