HealthCheck Assistance
The Health Check has reported that either the configured Buddy Server or a 3rd party system can't resolve a ping.
To ensure connectivity between systems, a low level ping is executed. This to ensure that the correct configurations are in place and the systems are accessible. Ping sends a Internet Control Message Protocol (ICMP) echo request messages to a remote computer.
For a pair of ENPS servers, the buddy address is obtained from the G_SERVERS table configuration and a ping executed using the configured address.
An additional ping is executed against a 3rd system. The default is the public Google DNS, 8.8.8.8 but this could be changed to the TCP/IP address of an ENPS Central Server in a distributed deployment, an NWP or any other system that is critical.
To confirm the state, from a command line you can execute ping <address to test> -n to ensure resolution.
Check that the address configured for the Buddy Server is correct. This could be the TCP/IP or FQDN. If it is the FQDN and there is still not resolution, check with your company's Infrastructure Services to ensure the remote system is registered correctly.
Some modern operating systems do not allow ICMP packets through there firewall. To resolve this either enable or create a rule allowing ICMP. This can be done via the Firewall console or Powershell:
netsh advfirewall firewall add rule name="AP ENPS - ICMP Allow incoming V4" protocol="icmpv4:8,any" dir=in action=allow
For the 3rd party system, ensure that this is accessible from any system within the organization. If this fails, depending what that system is, it may need a firewall rule created, registration corrected or it simply does not respond to ICMP packets. In the last case, a different address should be configured.
NOTE: If you have any questions, please contact AP ENPS Support before making changes to the HealthCheck configurations.
There is a thresholds set within \configurables\hc-custom_config.ps1. With the default being:
[string]$global:HC_Preset_Public_Ping_Server = "8.8.8.8" # Public TCP/IP to use for checking internet connectivity (Default: 8.8.8.8)
