[one-users] 答复: How to monitor oned processes wich shell command?

[杨燚]

Thank you very much.

"oneuser show" is the most quick way to check it.

 

earlier I used “onehost list” too, but it is very slow to display when there are hundreds of hosts.

Well, it depends on what you consider healthy.

If you only need to check if the process is responding, a simple "oneuser show" would be enough.

 

Or you could check the number of Hosts or VMs in 'fail' state to get a quick warning about a problem in your cloud.

Hi

I want to write a shell script to monitor oned process to check if oned is running and healthy.

my script only can count the number of process. and it can’t check if it is really healthy.

could you please give me some ideas? thank you very much.
