Does anyone know if this is possible?  If so, what would it look like?

I'm looking to make a command data source for a component template that would optionally add parameters if the component attributes exist, for example:

check_http -t 30 -H ${dev/manageIp} -p ${here/httpPort} -u ${here/httpUrl}

would change to:

check_http -t 30 -H ${dev/manageIp} -p ${here/httpPort} -u ${here/httpUrl} -a ${here/httpAuthUser}:${httpAuthPassword}

if the "httpAuthUser" and "httpAuthPassword" component attributes != None.


Thanks,
Joseph

j053ph4:

Negative, there is no conditional in this situation.

You can, however, do this:
zProperty, httpAuthUser= '-a yourUser:'
zProperty, httpAuthPassword='mySecret'

Command= check_http -t 30 -H ${dev/manageIp} -p ${here/httpPort} -u ${here/httpUrl} ${here/httpAuthUser}${httpAuthPassword}

If httpAuthUser and httpAuthPassword are blank, they are filled in as '' else they fill in the -a and : you need to make it all work.

Best,

Thanks Shane I'll give that a try...

Since what I asked isn't possible, are you saying that the optional argument handling (and selection of the relevant switches) is a function of the check_http plugin or is it more generic than that. 

Do you know if the "-s" (regex) or "-P" (POST) options can work the same way?

Thanks,
Joseph
