Kapacitor如何通过rest api使用模板创建任务？

POST /kapacitor/v1/templates HTTP/1.1
Content-Type: application/json

{
  "id": "cpu_alert_template",
  "type": "stream",
  "script": "var threshold = {{.threshold}}\nstream\n  |from()\n    .measurement('cpu')\n  |alert()\n    .crit(lambda: \"usage_idle\" < threshold)\n    .message('CPU idle is {{.message}}')",
  "vars": {
    "threshold": {
      "value": 80,
      "type": "float"
    },
    "message": {
      "value": "CRITICAL",
      "type": "string"
    }
  }
}

POST /kapacitor/v1/tasks HTTP/1.1
Content-Type: application/json

{
  "id": "cpu_alert_task",
  "template-id": "cpu_alert_template",
  "vars": {
    "threshold": {
      "value": 90.0
    },
    "message": {
      "value": "High CPU usage!"
    }
  },
  "dbrps": [{"db": "telegraf", "rp": "autogen"}]
}

import requests

# 定义模板
template_url = "http://localhost:9092/kapacitor/v1/templates"
template_data = {
    "id": "mem_alert_template",
    "type": "batch",
    "script": "var limit = {{.limit}}\nbatch\n  |query('SELECT used_percent FROM mem')\n  |alert()\n    .warn(lambda: \"used_percent\" > limit)",
    "vars": {"limit": {"value": 70, "type": "int"}}
}
requests.post(template_url, json=template_data)

# 创建任务
task_url = "http://localhost:9092/kapacitor/v1/tasks"
task_data = {

    "template-id": "mem_alert_template",
    "vars": {"limit": {"value": 85}},
    "dbrps": [{"db": "telegraf", "rp": "autogen"}]
}
response = requests.post(task_url, json=task_data)
print(response.json())
