# 主动健康检查
healthcheck:

uri: /
# 主动健康检查超时时间，不设置默认30秒，单位是秒，正整数
timeout-sec: 10
# 定时作业间隔
interval: "@every 10s"
# 保留节点数，不设置默认保留1个，假设一个service有3个节点，min-hosts设置的是3，即使都不健康，也不会去注册中心下线实例
# 如果一个service有3个节点，min-hosts设置的是2，假设都不健康，则会下线1个实例，保留2个
min-hosts: 3
# 健康检查http方法，默认是GET
method: GET
# 健康断言 实例状态默认是 unknown
# 特别的 相同百位数的状态码，可以缩写成 xx，比如 1xx[100-199], 2xx[200-299], 3xx[300-399], 4xx[400-499], 5xx[500-599]
# 健康检查返回的状态码同时满足 healthy.http_statuses 和 unhealthy.http_statuses 交集 status，则认为是健康节点
# 比如 http_status 是 401，healthy.http_statuses 是['4xx'], unhealthy.http_statuses 是[401]，则认为是健康节点
# 比如 http_status 是 401，healthy.http_statuses 是[400], unhealthy.http_statuses 是['4xx']，则认为是不健康节点
healthy:
# 如果健康检查 访问 http[s]://ip:port+uri，在timeout超时之前，返回了 http_statuses 指定的状态码，则视为健康节点
http_statuses: [200]
# successes 默认是1 ，连续成功超过 successes 次，此节点视为是 healthy, 默认是 unknown
successes: 1
# 不健康断言
unhealthy:
# 如果健康检查 访问 http[s]://ip:port+uri，超时了则 timeouts 计数增加，未超时正常返回了，检查 http_status ,是否命中 http_statuses
http_statuses: [404,500,502,503,504]
# failures 默认是1 ，连续失败超过 failures 次，此节点视为 unhealthy (failures或timeouts任一超过，均视为 unhealthy)
failures: 1
# timeouts 默认是1 ，连续失败超过 timeouts 次，此节点视为 unhealthy (failures或timeouts任一超过，均视为 unhealthy)
timeouts: 1
# 状态发生变更时 unknown-> healthy,unknown->unhealthy,healthy->unhealthy,unhealthy->healthy
# 会向 alert.url 推送 webhook,url query参数，key是body，值是jsonobject(类似 {"id":"a848ce01-7891-44f0-9f26-5ede6c9f6211","target_id":"0-apisix-nacos","service":"demo","instance":"10.42.0.98:8085","successes":0,"failures":0,"timeouts":1,"status":"unknown","create_time":"2024-06-26 10:13:49","last_time":"2024-06-26 10:13:58","new_status":"unhealthy","items":{"unhealthy":[{"id":"a848ce01-7891-44f0-9f26-5ede6c9f6211","target_id":"0-apisix-nacos","service":"demo","instance":"10.42.0.98:8085","successes":0,"failures":0,"timeouts":1,"status":"unhealthy","create_time":"2024-06-26 10:13:49.084153"}]}})
