Check Esxi7 with only SSH

Hi

As it is a bit problematic to fetch infos from an esxi host. I made my own script that uses only SSH. No SDK needed.

What can u monitor (see screemshot):

- Datastores useage and Warning + Perf Data
- CPU useage and Warning + Perf Data
- RAM useage and Warning + Perf Data
- Firewall Status on the Host and Warning
- Esxi Version + Patchlevel
- Nics in total and UP ones
- Vms in Total and running ones
- Uptime+ Perf Data

Reqirements:
- Nagios user (on nagios host) SSH key exchanged with Esxi Server (root user)
- bc,awk installed on the nagios host
- Plugins present on the nagios host:
/usr/lib/nagios/plugins/check_load

Tested on:
esxi 7.02
With iscsi and local Datastore.

Improvements welcome IF they use SSH!
