How does mfs monitor scripts in nagios

Editor to share with you how to monitor the script of mfs in nagios, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Recently, I have been testing the mfs. Finally, after the online test, I began to organize and monitor the mfs.

Mfs monitoring index

Listening port

Listening process

Monitor vip

Monitor, read and write

Now a shell script for monitoring whether the process is alive is attached for reference only.
