How to implement the nagios plug-in for monitoring MFS
Editor to share with you how to achieve the nagios plug-in for monitoring MFS, 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!
I took down the script and tested it. There seems to be some minor error. I don't know if it is the reason why the system is different.
My test environment is centos 6.586 / 64.
The following is a modified script that I made under the environment of centos 6.586 / 64, and I share it with you.
