1 Server-proxy 数据交换协议

概述

服务器 - proxy 数据交换基于 JSON 格式。

请求和响应消息必须以 header and data length 开头。

被动 proxy

配置请求

服务器将首先发送一个空的 proxy config 请求。该请求每隔 ProxyConfigFrequency（服务器配置参数）秒发送一次。

proxy 会以当前 proxy 版本、会话令牌和配置版本进行响应。服务器则以需要更新的配置数据进行响应。

示例：

服务器→proxy：

服务器→proxy：

{
         "request":"proxy config"
       } 

proxy→server:

Tasks request

The proxy tasks exchange handles delivery and acknowledgement of remote command tasks between the server and a passive proxy. When the server polls the proxy for task results, it sends an empty proxy tasks request at the interval defined by ProxyDataFrequency. The proxy responds with its current version and any pending task results (including timestamps). The server then acknowledges receipt by returning a response and may include new tasks for the proxy to execute.

Example:

server→proxy:

{
         "request":"proxy tasks"
       }

proxy→server:

{
         "version":"7.0.0",
         "clock":1721059872,
         "ns":848141522
       }

server→proxy:

{
         "response":"success"
       }

Active 代理

配置请求

主动模式的 proxy 会发送 proxy config 请求以获取 proxy 的配置数据。此请求每隔 ProxyConfigFrequency 秒发送一次（proxy 的配置参数）。

示例：

proxy→server:

{
         "request": "proxy config",
         "主机": "Zabbix proxy",
         "version":"7.0.0",

         "config_revision": 0

数据请求

proxy data请求由proxy发送，用于提供主机接口可用性、历史数据、发现和自动注册数据。 该请求每DataSenderFrequency秒（proxy配置参数）发送一次。 注意：主动式proxy仍会每秒轮询Zabbix server以获取远程命令任务（使用空的proxy data请求）。
