Issue:

 Your_Database_FQDN external-DB [ERROR] Connection to IM database (Your_Database_FQDN:1433) failed 
 Your_Database_FQDN external-DB [ERROR] Connection to IP database (Your_Database_FQDN:1433) failed 
 Your_Database_FQDN external-DB [ERROR] Connection to IG database (Your_Database_FQDN:1433) failed 

 
Environment:
Virtual Appliance 14.x
Cause:
While monitoring a system with an external DB, the vApp monitor will try to verify network reachability to the DB.
This operation has a timeout of 3 seconds.

Due to some network latency, this message is logged in.
Resolution:
To check the TCP connection between vApp Server and Database, run the phyton script attached.

phyton python_check_tcp.py <IP> <port>
phyton  python_check_tcp.py <FQDN> <port>

Use the same FQDN used in your vApp configuration

If your environment is using FQDN and it takes more time than IP, check your network about a possible problem with name resolution or you can add the FQDN in your hosts file.
