Health Check Messages for Serves

The following tables describe potential health check messages for NIOS-X servers that can be displayed on the Infoblox Portal. Infoblox recommends corrective actions you can take to mitigate some of the health check errors.

Generic Platform Management and Application Management Health Check Messages

Component	Message displayed in the Infoblox Portal	Potential reasons for the health check error	Possible corrective actions

Component	Message displayed in the Infoblox Portal	Potential reasons for the health check error	Possible corrective actions
Platform/Application Management	Disconnected	Lack of network connectivity on the NIOS-X server. One of the following firewall configuration happened on the NIOS-X server: Port 443 blocked TLS v1.2 or v1.3 blocked Infoblox cloud IPs blocked Failed to connect to HTTPS proxy High CPU usage on the NIOS-X server High Memory usage on the NIOS-X server Improper NIOS-X server configuration	Firewall configuration: Check whether outgoing connections from the NIOS-X server to the Infoblox platform using port 443 are allowed on the firewall. Check whether outgoing connections from the NIOS-X server to the Infoblox platform using TLS v1.2 and TLS v1.3 are working. Proxy configuration: Check whether the proxy used is functioning properly and allowing connections to the Infoblox platform.
Application Management	Application Tunnel is Inactive
Platform Management	Offline	When any service failed to start.	N/A
Application Management	Error	When any service failed to start.	N/A

Platform Management Health Check Messages

Proxy configuration: Check whether the proxy used is functioning properly and allowing connections to the Infoblox platform.
blox.noa	Unable to connect to BloxOne Cloud
blox.noa	Failed to revoke BloxOne Edge
blox.noa	Failed to register to BloxOne Cloud
blox.noa	Failed to activate BloxOne Edge
keepalived_keepalived_1	Keepalived node is unhealthy
bootstrap-service	Disconnected from the Bootstrap Controller
bootstrap-node-controller	OnPrem is Offline	One or more of the following caused connectivity loss on new interface configuration. Gateway mis-configuration or deletion. Failure to allocate IP address (via dynamic IP allocation). Change in metric for gateway results in network connectivity loss.	Wait at least five minutes after any interface configuration before checking online status of the NIOS-X server via the Infoblox Portal. Route Table configuration Try to access the NIOS-X server via serial console. Check the route table default gateway content.
k3s-mgr-k3s-mgr	Failed to install Kubernetes cluster	Internal errors during the K3s installation process. Pre-checks might have failed. System failed to meet the minimum resource requirements.	Check to see if there are enough system resources for K3s installation: https://rancher.com/docs/k3s/latest/en/installation/installation-requirements/ Check to see if there is IP overlapping with K3s CIDRs: https://rancher.com/docs/k3s/latest/en/installation/install-options/server-config/#networking or Docker Bridge IP.
k3s-mgr-k3s-mgr	Kubernetes cluster is unhealthy	K3s cluster is unhealthy. Possible reasons: High CPU usage on the NIOS-X server. High memory usage on the NIOS-X server.	Take care of the CPU and/or memory usage.
bootstrap-node-controller	Internal server error: <particular reason>		Take care of the CPU and/or memory usage.
platform-firewall	IP Tables and Chains not initialized	Some IP tables were locked. Internal NIOS-X server errors. IP table chains were broken.	Verify and fix potential issues.
scout	Failed to initialize BloxOne Edge	CPU throttle. High memory usage. Failure in getting network interfaces on the NIOS-X server.	Verify and fix potential issues.
scout	Failed to setup BloxOne Edge		Verify and fix potential issues.

Application Management Health Check Messages

Note that all health check messages follow this syntax: <service name>:<message>

Component	Message displayed in the Infoblox Portal	Potential reasons for the failed health check	Possible corrective actions

Component	Message displayed in the Infoblox Portal	Potential reasons for the failed health check	Possible corrective actions
app-infra_config-service_1	Unable to connect to BloxOne Cloud	Lack of network connectivity on the NIOS-X server.
