Requirements: A directory (such as/data/test) to monitor, when the file or sub-directory in this directory changes (such as modification, creation, deletion, renaming, etc.), send mail! For the above requirements, write the shell script as follows:[[emailprotected] opt]# vim file_monit.sh#!/bin/bash# This script is used to detect whether important files of the Linux system have been changed, if the change

The following is the installation configuration process.1. Installing SupervisorEasy_install Supervisor Setuptool Installation methodApt-get Install Supervisor Debian/ubuntu

Recently saw a group of people chatting to their server has recently been Hung horse, and then want to use a script to monitor the Web directory changes in real-time files, that is, the directory of additions and deletions to the corresponding log records. At that time feel this function is really a bit interesting, so I looked up some information on the Internet, I studied the next, now have time to write a script, to share with you, if th

How to monitor Linux UDP buffer available space? you is trying to solve the wrong problem. UDP isNBSP; unreliable communication, period. If packet loss is a problem for you, you should either implement your own Retransmission/error control algorithm or not us ing UDP in the first place. Drop it entirely in favor of TCP, or perhaps something more advanced like SCTP or even DCCP. UDP is datagram-based,

Our website now uses some tools to monitor whether the website server can be accessed, but not the status of the website. Next I will recommend you to use shell to monitor the website status script in linux. Today, I wrote shell monitoring for my website, so I don't know if my website goes down. This script checks the webpage status and webpage connection time se

Icinga uses NSCA to monitor remote Linux servers. Because the HTTP service is a public service, you do not need to install the agent on a remote machine. 131 of local resources, such as disks and CPUs, need to install a software. Icinga provides two modes: active check (server. 111 polling. 131). This efficiency is not recommended. Another mode, passive check, is waiting for the remote agent to send message

When using the GPU for computing, such as running deep learning code, we may want to be able to detect the use of video memory in real time, but Linux generally does not bring its own monitoring of existing tools. Nvidia comes with a NVIDIA-SMI command-line tool that shows memory usage, but we can't enter this command every 10s. It's time to use the Watch command.About Watch commandWhat does watch do? Look at what the system says.1 $ whatis Watch 2 Wa
