1 Server-proxy data exchange protocol
Overview
Server - proxy data exchange is based on JSON format.
Request and response messages must begin with header and data length.
Passive proxy
Proxy config request
The proxy config request is sent by server to provide proxy configuration data. This request is sent every ProxyConfigFrequency (server configuration parameter) seconds.

Proxy data request
The proxy data request is sent by proxy to provide host interface availability, history, discovery and autoregistration data. This request is sent every DataSenderFrequency (proxy configuration parameter) seconds. Note that active proxy will still poll Zabbix server every second for remote command tasks (with an empty proxy data request).
