Check_http over a proxy

No, you can do things in two ways.

1) Use two checks, one that has the proxy portion and one that doesn't.
2) Use one check with custom service variables that defines the proxy only for service checks that need it. More information is available at https://assets.nagios.com/downloads/nag ... tvars.html

[amprantino]

Define two different checks and select the needed one

define command {
command_name check_http
command_line $USER1$/check_http --hostname=$HOSTADDRESS$
}

define command {
command_name check_http_proxy
command_line $USER1$/check_http -I {IPOFMYPROXY} --hostname=$HOSTADDRESS$
}

Yes, that was my option 1.

Not clear if you implemented the different checks. Did you try that out? If so, did it work?

If I changed the "define command" to include the -I (that's an eye) with the proxy info, everything worked that requires the proxy but everything failed that doesn't.

We have provided two potential fixes to that:

1) Write two commands, one without the proxy (check_http) and one with the proxy (check_http_proxy). Update all the services that need to use the proxy to use the check_http_proxy command.

2) Use a custom service variable that would be something like _proxy="-I <proxy ip"> for service that need it, and _proxy="" for services that don't. Then update the check_http to use the $SERVICEPROXY$ custom variable in the command line and it will add it when it's set and skip it when it's blank.

I'd personally go with option 1 above - it's easier to make mass changes and it's going to be more obvious during troubleshooting down the road.

[eloyd]

Just to be obtuse, I have an option 3:

Always use the version without a proxy specification and write an event handler that gets triggered when the result returns failure. Then have the event handler try the same check with a proxy and if it returns correctly, then submit a service check command output to the nagios.cmd file with an OK status.

Adjust notifications accordingly.

You? Obtuse? Nonsense :)

Just wait till 1:59pm Friday... I'll show you obtuse.
