如何每5秒查找一次linux中特定进程的内存消耗 [英] How to find the memory consumption of a particular process in linux for every 5 seconds

问题描述

我只想知道如何查找特定进程在特定时间(例如5秒)的内存消耗

I just want to know how to find the memory consumption of a particular process for particular time(say 5 seconds)

我是Linux新手.因此，我们将感谢您执行此操作的详细步骤

I am new to linux. So, detailed steps of doing that will be appreciated

推荐答案

您可以使用SNMP获取网络中特定设备中进程的内存和CPU使用率:)

you may use SNMP to get the memory and cpu usage of a process in a particular device in network :)

要求:

• 运行该进程的设备应已安装并正在运行snmp
• snmp应该配置为从下面运行脚本的位置接受请求(可能在snmpd.conf中配置)
• 您应该知道要监视的进程的进程ID(pid)

注释:

• HOST-RESOURCES-MIB :: hrSWRunPerfCPU 是此过程消耗的总系统CPU资源的厘秒数.请注意，在多处理器系统上，此值可能会在实际(挂钟)时间的1厘秒中增加1厘秒以上.

• HOST-RESOURCES-MIB::hrSWRunPerfCPU is the number of centi-seconds of the total system's CPU resources consumed by this process. Note that on a multi-processor system, this value may increment by more than one centi-second in one centi-second of real (wall clock) time.

HOST-RESOURCES-MIB :: hrSWRunPerfMem 是分配给该进程的实际系统内存总量.

HOST-RESOURCES-MIB::hrSWRunPerfMem is the total amount of real system memory allocated to this process.

过程监视脚本:

**

echo "IP: "
read ip
echo "specfiy pid: "
read pid
echo "interval in seconds:"
read interval

while [ 1 ]
do
    date
    snmpget -v2c -c public $ip HOST-RESOURCES-MIB::hrSWRunPerfCPU.$pid
    snmpget -v2c -c public $ip HOST-RESOURCES-MIB::hrSWRunPerfMem.$pid
    sleep $interval;
done
