Something to be aware of and which is perhaps not clear in our documentation ( I will check ) is that the metric values returned must be NUMERIC if you are going to use this API with our forthcoming SAM monitoring product. Values like 'OK 'and 'Normal ' and even '0d 1h 18m' aren't much use in rule evaluation and display in commonly available tools just as Grafana ( which we leverage in our solution).

gatekeeper has quarantined your httpd. open a terminal and navigate to {irisinstalldir}/httpd/bin and do this

sudo xattr -d com.apple.quarantine ./httpd. This removes the quarantine flag and will let httpd start.

alternative is to disable gatekeeper completely but I don't advise that as it can be dangerous.

Thats not a supported scenario at the moment. Feel free to log an enhancement request via the WRC.
