Zabbix server and Zabbix proxy use a JSON-based communication protocol for receiving data from Zabbix sender. Data can be received with the help of a trapper item, or an HTTP agent item with trapping enabled.
Request and response messages must begin with header and data length.
{ "request": "sender data", "data": [ { "host": "<hostname>", "key": "trap", "value": "test value" } ] }
Alternatively, Zabbix sender can send a request with a timestamp and nanoseconds.
{ "request": "sender data", "data": [ { "host": "<hostname>", "key": "trap", "value": "test value", "clock": 1516710794, "ns": 592397170 }, { "host": "<hostname>", "key": "trap", "value": "test value", "clock": 1516710795, "ns": 192399456 } ], "clock": 1516712029, "ns": 873386094 }
