check-host-alive v. ping service

[jbennett]

Really, what's the difference here and why would one want both set on a host where all we're doing is checking to make sure it is up in the first place (a camera for instance)?

This is used on machines that refuse ICMP ping requests and require a different way of determining if a particular host is down. Please, review our documentation on the topic here:

Hope this helps.

So, if the check command is for check-host-alive is referencing check_ping, then it's effectively doing the exact same thing as a check_ping service? To the best of my knowledge, we do not have any equipment that refuses ICMP requests.

If this is the case, then I should be fine to eliminate one of these and only rely on the other, correct?

Breakdown of what I have:

Host Check Command: check-host-alive w/ check_ping
Template applied to host: xiwizard_genericnetdevice_host includes check_xi_host_ping (check_icmp) in the check command.
Template applied to host xiwizard_genericnetdevice_host: xiwizard_generic_host includes check_xi_host_ping (check_icmp) in the check command.
Service: Ping w/ check-host-alive w/ check_ping with Camera listed under Hosts.
Template applied to service: none

Yep you should be allright with that
