Overview

Used for sending events to a Zabbix server.

An 'event' from Vayacondios' perspective is an arbitrary Hash.

An 'event' from Zabbix's perspective is a tuple of values:

  • time
  • host
  • key
  • value

This client will accept a Vayacondios event and internally translate it into a set of Zabbix events.

would get turned into the following events when written to Zabbix:

[ { host: "foo-server.example.com", key: "cpu.util.user", value: 0.20 } { host: "foo-server.example.com", key: "cpu.util.idle", value: 0.70 }, { host: "foo-server.example.com", key: "cpu.util.sys", value: 0.10 }, { host: "foo-server.example.com", key: "cpu.load", value: 1.3 } ]

Zabbix will interpret the time as the time it receives each event.

The following links provide details on the protocol used by Zabbix to receive events:

Examples:

A CPU monitoring notification


notify "foo-server.example.com", cpu: {
  util: {
    user: 0.20,
    idle: 0.70,
    sys:  0.10
  },
  load: 1.3
}

The CPU monitoring notification translated to Zabbix events
