Does XC DNS support health monitoring for CNAME records?

Hi everyone,

I have a question regarding health monitor with CNAME records in the XC DNS Load Balancer. 

If I configure a Type A DNS Load Balancer in XC, I can attach a DNS pool with health monitor. However, if I configure a Type CNAME DNS Load Balancer with a CNAME-type pool, I can't select any health monitor for the CNAME pool.

Our goal is to monitor a server service hosted in a third-party cloud and avoid the cloud edge service going down. Once the XC DNS detect a service failure, then it will reply with the fallback dns record (from another cloud service) to the user.

Is there have any other way to monitor the health of CNAME pool ?

Regards,

Ding
