| # AppHttpHealthy | ||
|
|
||
| ## 基本描述 | ||
|
|
||
| 对于这种任务，每个 kdoctor agent都会向指定的目标发送http请求，并获得成功率和平均延迟。它可以指定成功条件来判断结果是否成功。并且，可以通过聚合API获取详细的报告。 | ||
|
|
||

| |--------------------|---------------------------------------|--------|-----|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------| | ||
| | roundNumber | 任务执行轮数 | int | 可选 | 大于等于-1，为 -1 时表示永久执行,大于 0 表示将要执行的轮数 | 1 | | ||
| | schedule | 任务执行时间, 执行时间应小于roundTimeoutMinute | string | 可选 | 支持 linux crontab 与间隔法两种写法<br/>[linux crontab](https://linuxhandbook.com/crontab/) ： */1 * * * * 表示每分钟执行一次 <br/>间隔法：书写格式为 “M N” ，M取值为一个数字，表示多少分钟之后开启任务，N取值为一个数字，表示每一轮任务的间隔多少分钟执行，例如 “0 1” 表示立即开始任务，每轮任务间隔1min | "0 1" | | ||
| | roundTimeoutMinute | 任务超时时间，需要大于 durationInSecond 和 任务执行时间 | int | 可选 | 大于等于 1 | 60 | | ||
| #### Request | ||
| | 字段 | 描述 | 结构 | 验证 | 取值 | 默认值 | | ||
| |------------------------|---------------------------------------|--------|-----|---------------|---------------| | ||

| | qps | 每一个 agent 每秒请求数量 | int | 可选 | 大于等于 1 | 5 | | ||
| > 注意：使用 agent 请求时，所有的 agent 都会向目标地址进行请求，因此实际 server 接收的 qps 等于 agent 数量 * 设置的qps。 | ||
| #### Target | ||
