Hi Bortzmeyer, it’s very helpful. 

Now in BII side, we only have one probe to monitoring the status of Yeti root system, 
printed in this page: http://yeti-dns.org/yeti_server_status.txt <http://yeti-dns.org/yeti_server_status.txt>

I’m considering to use more probes to generate a better health report with more information. 
Given the coming workshop, would you like to introduce your measurement work and 
suggestion to our health monitoring system.
