# CONTACTS.CFG - SAMPLE CONTACT/CONTACTGROUP DEFINITIONS

# Last Modified: 05-31-2007
#
# NOTES: This config file provides you with some example contact and contact
# group definitions that you can reference in host and service
# definitions.
#
# You don't need to keep these definitions in a separate file from your
# other object definitions. This has been done just to make things
# easier to understand.

This is all documented, but to give you a head start, a host needs to be defined, to wich you can assign certain services that are checked by commands (which are defined in the commands sections). Also, a host or service needs to have a contact group assigned, to wich alerts can be directed.

A bit more elaborative explanation and examples can be found here (just googled it, there are way more):

And use [code] ... [/code] around your examples. This will preserve the original layout

is beyond scope of this thread, but without touching esxi you hope snmp is available to use that.

also, obtaining stats through ssh is also possible
