Nagios checks for op-??.onionperf.torproject.net

We're currently thinking about shutting down a metrics-specific Nagios instance that is monitoring our OnionPerf instances.

Can we somehow include the op-??.onionperf.torproject.net hosts in Tor's Nagios -- for checks like running out of disk space -- even if those hosts are not managed by the Tor sysadmin team?
