TelemetryMetricsZabbix

Provides a Zabbix format reporter and server for Telemetry.Metrics definitions. Submits data to Zabbix Trapper Items using Zabbix Sender Protocol. Powered by zabbix_sender.

Installation

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

def deps do
  [
    {:telemetry_metrics_zabbix, "~> 0.1"}
  ]
end

Configuration

Add approperiate config section to your config.exs

config :telemetry_metrics_zabbix, :config,
  host: "zabbix.trapper.host",
  port: 10051,
  hostname: "monitored.host",
  batch_window_size: 1000,
  timestamping: true

Usage

Add TelemetryMetricsZabbix to your application supervision tree and pass metrics as a param. Create a Zabbix Trapper Item on monitored.host for every measurement key you want to collect. Set data type on the Trapper Item to Numeric.

Example

metrics = [
  Telemetry.Metrics.sum("http.request.latency", tags: [:host])
]

children = [
  {TelemetryMetricsZabbix, metrics: metrics}
]
opts = [strategy: :one_for_one, name: MyApp]
Supervisor.start_link(children, opts)

Currently supported metrics

• Telemetry.Metrics.Counter: counts events
• Telemetry.Metrics.Sum: sums events' values
• Telemetry.Metrics.Summary: calculates events' values average
• Telemetry.Metrics.LastValue: returns all events' values with timestamps

Measuremet to zabbix value conversion

Measurements are aggregated by event name, measurement and tag values. All those parts are included as Zabbix Sender Protocol key. Tag values are treated as Zabbix key parameters sorted by tag key.

Example

with metric

Telemetry.Metrics.sum("http.request.latency", tags: [:host, :method])

and event

:telemetry.execute([:http, :request], %{latency: 200}, %{host: "localhost", method: "GET"})

Zabbix Trapper key will be http.request.latency["localhost","GET"]

Known isuues

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