Nagios acquires ESXi hard drive smart information via Python

ESXi can see the smart information on the relevant panel, my side of the company with the assembled server, and then do not support, had to use the method of SSH to obtain.
Nagios Monitoring displays relevant information by exiting the status code.
The exit code is as follows:
0 OK; 1 warning; 2 critical; 3 Unknown

python can use the Paramiko to implement the SSH connection and execute the command process.
