获取主机列表

Payload:

{
    "jsonrpc": "2.0",
    "method": "host.get",
    "params": {
        "output": ["host","available"]
    },
    "auth": "54ec7f0d103f635ada0a76147d8a93a5",
    "id": 1
}

Response:

{
  "jsonrpc": "2.0",
  "result": [
    {
      "hostid": "10084",
      "host": "Zabbix server",
      "available": "1"
    },
    {
      "hostid": "10254",
      "host": "jfgitlab",
      "available": "1"
    }
  ],
  "id": 1
}

这里能够获取到主机的host,用于组成下面的expression

创建触发器trigger

Payload:

{
    "jsonrpc": "2.0",
    "method": "trigger.create",
    "params": {
            "description": "Total memory is lower than 4G at host: jfgitlab (中文测试)",
            "expression": "{jfgitlab:vm.memory.size[total].avg(1m)}<4G",
            "priority":"1"
      },
    "auth": "54ec7f0d103f635ada0a76147d8a93a5",
    "id": 1
}

Response:

{
  "jsonrpc": "2.0",
  "result": {
    "triggerids": [
      "15405"
    ]
  },
  "id": 1
}

TODO: 表达式expression规则说明
结构为:

{<server>:<key>.<function>(<parameter>)}

server: jfgitlab 
key:  vm.memory.size[total]
function: avg(1m)

设置主机动作action

通过主机id与触发器名决定该action

Payload:

              }
            ]
        },

                    "mediatypeid": "4"
                }
            }
        ],
        "recovery_operations": [
        ],
        "acknowledge_operations": [
        ]
    },
    "auth": "54ec7f0d103f635ada0a76147d8a93a5",
