There might be a misconception of what a node could be here. What is your "node"? A host? And you have microservices deployed on each host? In APISIX, an upstream can be configured in multiple nodes. If health check is configured on upstream with `upstream.checks.xxxx`, each node in the upstream will be checked for health _individually_. This can be examined with a request to the control API health check endpoint: ```shell curl "http://127.0.0.1:9090/v1/healthcheck"; ``` You get something like this for example: ```json [ { "name": "/apisix/routes/example-healthcheck-route", "type": "http", "nodes": [ { "port": 80, "counter": { "http_failure": 0, "tcp_failure": 0, "timeout_failure": 0, "success": 0 }, "ip": "172.24.0.5", "status": "healthy" }, { "port": 80, "counter": { "http_failure": 0, "tcp_failure": 0, "timeout_failure": 3, "success": 0 }, "ip": "172.24.0.4", "status": "unhealthy" } ] }, { "name": "/apisix/upstreams/example-healthcheck-route", "type": "http", "nodes": {} } ] ``` Note how the first node is _healthy_ and the second node is not. -- This is an automated message from the Apache Git Service.
