DNS-derived autoscaling refresh time

DNS-derived autoscaling refresh time

Does DNS-derived autoscaling have its own hidden referesh setting or does it use the general VTM DNS TTL? I can't seem to find any information about this within the documentation.

 

Thanks.

Re: DNS-derived autoscaling refresh time

I have just checked and this is hard set internally at a 30 second refresh interval.

 

I have raised a documentation bug to get this information added to the documentation. Apologies for it not already being there!!

Re: DNS-derived autoscaling refresh time

I wonder if you could assist with this follow-up question:

 

Is the auto-scaling refresh time independent from the DNS TTL. I.e., will the autoscaling work if the DNS TTL << refresh time ?

Re: DNS-derived autoscaling refresh time

Auto scaling refresh is independent of TTL, and set to 30 seconds.

 

If you want to run something more complex, you could use the

Service Discovery plugin "BuiltIn-DNS_Resolver" which does honour TTLs?
