Hi, @yocaning You need to pay attention to your configuration. The `http_path` of the active health check should be consistent with the uri that provides the service. Secondly, the value of `"timeout":1` is recommended to be set larger. This is an example, you can refer to it 1、Add a route and enable health check The 1981 and 1982 ports are healthy, but the 1985 port is unhealthy. ```shell curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d ' { "id":"1", "update_time":1613734165, "upstream":{ "checks":{ "active":{ "healthy":{ "interval":3, "successes":2 }, "unhealthy":{ "interval":10, "http_failures":2 }, "timeout":10, "http_path":"/hello", "type":"http", "req_headers":[ "Content-Seq:3" ] }, "passive":{ "timeout":5, "healthy":{ "http_statuses":[ 200, 201 ], "successes":3 }, "type":"http", "unhealthy":{ "http_statuses":[ 500, 504 ], "timeouts":3, "tcp_failures":1, "http_failures":1 } } }, "nodes":{ "127.0.0.1:1980":1, "127.0.0.1:1981":1, "127.0.0.1:1985":1 }, "timeout":{ "connect":3, "read":3, "send":3 }, "pass_host":"pass", "hash_on":"vars", "type":"roundrobin" }, "methods":[ "PUT", "GET" ], "status":1, "create_time":1613722689, "priority":0, "uri":"/hello" }' ``` 2、Access request and view error.log ``` $ curl http://127.0.0.1:9080/hello hello 1980 $ tail -f error.log 2021/02/22 15:41:42 [warn] 23035#23035: *66190 [lua] healthcheck.lua:1107: log(): [healthcheck] (upstream#/apisix/routes/1) unhealthy TCP increment (1/2) for '(127.0.0.1:1985)', context: ngx.timer, client: 127.0.0.1, server: 0.0.0.0:9080 2021/02/22 15:41:48 [warn] 23035#23035: *66445 [lua] healthcheck.lua:1107: log(): [healthcheck] (upstream#/apisix/routes/1) unhealthy TCP increment (2/2) for '(127.0.0.1:1985)', context: ngx.timer, client: 127.0.0.1, server: 0.0.0.0:9080 2021/02/22 15:42:56 [warn] 23036#23036: *69367 [lua] healthcheck.lua:1107: log(): [healthcheck] (upstream#/apisix/routes/1) healthy SUCCESS increment (1/2) for '(127.0.0.1:1980)', context: ngx.timer, client: 127.0.0.1, server: 0.0.0.0:9080 2021/02/22 15:42:56 [warn] 23036#23036: *69367 [lua] healthcheck.lua:1107: log(): [healthcheck] (upstream#/apisix/routes/1) healthy SUCCESS increment (1/2) for '(127.0.0.1:1981)', context: ngx.timer, client: 127.0.0.1, server: 0.0.0.0:9080 ``` 3、When the port of `1985` recovered health and view error.log When an unhealthy node is restored to a healthy node, it will be automatically marked as healthy. ``` 2021/02/22 15:57:32 [warn] 23035#23035: *107236 [lua] healthcheck.lua:1107: log(): [healthcheck] (upstream#/apisix/routes/1) healthy SUCCESS increment (2/2) for '(127.0.0.1:1985)', context: ngx.timer, client: 127.0.0.1, server: 0.0.0.0:9080 ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
