AltocumulusF5 DNS Generic Host
I am trying to create a few generic hosts for a POC, but having issues with them being monitor failed. I created a new server named RANCHER-POC-11 and gave it an ip address of 10.4.65.11, this has a monitor of https assigned to it. I then created a virtual server with the same ip address and port 443 as well as the https monitor. The Server and Virtual Servers are both red triangles. I performed a packet capture and I don't see that the gtm is even attempting to monitor. I put a specific route in the network and pointed to the GW and now if I initiate a connection from the CLI I see logs in our monitoring but only if I do the connection manually.
This is the first generic host we have tried to deploy as the rest of the virtual servers/pools are pulled from the LTM's and this service is not behind the LTM.
Any suggestions would be appreciated.
Thanks,
Joe

Hey Joe,
Monitoring in BIG-IP DNS is a little more complicated than in BIG-IP LTM (https://my.f5.com/manage/s/article/K08433560)
Basically, all BIG-IP DNS systems in a Sync-Group are eligible to perform monitoring of any given resource with priorities based on Prober Pool oder Prober Preference (like prefer local Datacenter).
The result of this monitoring is then mirrored to the Group and accepted by all members.If your BIG-IP DNS Sync Group has multiple members in multiple datacenters and Monitoring does not egress one system, it may egress from another BIG-IP DNS.
If your Prober Preference is set to inside Datacenter, but no BIG-IP DNS is available there, it may also be delegated to a connected BIG-IP LTM that will then report the results to BIG-IP DNS.

Hello Joe,
Could you please let me know about config object type BIG-IP for F5 DNS, you have to config gslb server type BIG-IP for DNS first
