But LTM does not show node/pool member hostnames: ltm node /Tenant_Acme/10.1.10.5 { address 10.1.10.5 } ltm pool /Tenant_Acme/acme_smtp_app/acme_smtp_pool { members { /Tenant_Acme/10.1.10.5:25 { address 10.1.10.5 metadata { source { value declaration } } } } min-active-members 1 monitor min 1 of { /Tenant_Acme/acme_smtp_app/smtp_monitor } }

Expected Behavior

Pool member/node hostname should be populated.

Actual Behavior

Pool member/node hostname is not populated.
