ZabbixSender

Zabbix Sender Protocol client. Compatible with Zabbix 4.0

This library implements a simple TCP client as well as helper functions for encoding and decoding protocol messages.

Installation

The package can be installed by adding zabbix_sender to your list of dependencies in mix.exs:

def deps do
  [
    {:zabbix_sender, "~> 1.0.0"}
  ]
end

Usage

Use functions from ZabbixSender.Protocol for building requests and decoding responses. Use ZabbixSender.Serializer for writting and reading binary messages. ZabbixSender.send\3 will open connection, send request receive a response and then close the connection as the server won't allow it remain open.

Example

value = ZabbixSender.Protocol.value("localhost", "some_key", 12.3, :os.system_time(:second))
request = ZabbixSender.Protocol.encode_request([value], :os.system_time(:second))
|> ZabbixSender.Serializer.serialize()

with {:ok, response} <- ZabbixSender.send(request, "localhost", 10051),
  {:ok, deserialized} <- ZabbixSender.Serializer.deserialize(response),
  {:ok, decoded} <- ZabbixSender.Protocol.decode_response(deserialized)
do
  if decoded.failed == 0 do
    Logger.info("#{decoded.processed} values processed")
  else
    Logger.warn("#{decoded.processed} values processed out of #{decoded.total}")
  end
end

Known issues

Currently TLS encryption (both PSK and RSA) is not supported and there are no plans for it. A PR would be welcome though.
