notification 
DNS forwarder vmwNsxTDataCenterIntentPath(vmwNsxTDataCenterDNSId) did not receive a timely response
from upstream server vmwNsxTDataCenterDNSUpstreamIP. Compute instance connectivity to
timed out FQDNs may be impacted.
          
Action required:
1. Invoke the NSX API GET /api/v1/dns/forwarders/vmwNsxTDataCenterDNSId/nslookup?
   address=<address>&server_ip=vmwNsxTDataCenterDNSUpstreamIP&source_ip=<source_ip>.
   This API request triggers a DNS lookup to the upstream server in the
   DNS forwarder's network namespace. <address> is the IP address or FQDN
   in the same domain as the upstream server. <source_ip> is an IP address
   in the upstream server's zone.
   If the API returns a connection timed out response, there is likely a
   network error or upstream server problem. Check why DSN lookups
   are not reaching the upstream server or why the upstream server is not
   returning a response. If the API response indicates the upstream server
   is answering, proceed to step 2.
2. Invoke the NSX API GET /api/v1/dns/forwarders/vmwNsxTDataCenterDNSId/nslookup?
   address=<address>.
   This API request triggers a DNS lookup to the DNS forwarder. If the API
   returns a valid response, the upstream server may have recovered and this
   alarm should get resolved within a few minutes. If the API returns a
   connection timed out response, proceed to step 3.
3. Invoke the NSX CLI command `get dns-forwarder vmwNsxTDataCenterDNSId live-debug
   server-ip vmwNsxTDataCenterDNSUpstreamIP`.
   This command triggers live debugging on the upstream server and logs
   details and statistics showing why the DNS forwarder is not getting a
   response.
