As a system administrator, I'm most depressed when my main online systems stop or stop collecting services without my knowledge, in addition, it may take a long time for the faulty services or hosts to know. Especially when it comes to the festival, the system administrator is very important. To change this passive

Its limitations are also obvious, and the monitoring object needs to be re-selected when switching applications. In addition, one months and 30 minutes of trial time, even if the application of several accounts is not enough. To facilitate development and performance tu

design a script that monitors the surviving state of a remote machine (assuming IP 123.23.11.21) and sends a message to yourself when it finds an outage. Tips:1. You can use the ping command ping-c10 www.baidu.com2. The order to send the email is echo "Email content" |mail-s "subject" [email protected]3. The script can be turned into a dead loop, detected once every 30s#!/bin/bash#remote

Recently, in your project, you have encountered an example of a real-time situation where you need to remotely monitor the software running automatically. Because MS has WCF for service-oriented aspects, and read some information, WCF is more suitable for this application. Therefore, we decided to use WCF to implement this function.
