Open Telemetry

Logflare features OpenTelemetry integration to ingest directly from OpenTelemetry SDKs.

note

This feature is under development and is considered alpha stage. It is not advisable to use it for mission critical production workloads.

The ingestion url is https://otel.logflare.app:443.

Configuration Examples

Erlang

%% config/sys.config.src
[
 {opentelemetry, [
    {span_processor, batch},
    {traces_exporter, otlp}
  ]},

 {opentelemetry_exporter, [
    {otlp_protocol, grpc},
    {otlp_compression, gzip},
    {otlp_endpoint, "https://otel.logflare.app:443"},
    {otlp_headers, [
      {"x-source", "my-source-id"},
      {"x-api-key", "my-access-token"}
    ]}
  ]}
].

Elixir

# config/config.exs
config :opentelemetry,
  span_processor: :batch,
  traces_exporter: :otlp

config :opentelemetry_exporter,
  otlp_protocol: :grpc,
  otlp_compression: :gzip,
  otlp_endpoint: "https://otel.logflare.app:443",
  otlp_headers: [
    {"x-source", "my-source-uuid"},
    {"x-api-key", "my-access-token"}
  ]

Testing OpenTelemetry ingestion locally

Clone the Github repo, and then run the following:

# for bq backend
docker compose -f docker-compose.yml -f docker-compose.latest.yml up -d db logflare
# for pg backend
docker compose -f docker-compose.yml -f docker-compose.pg.yml -f docker-compose.latest.yml up -d db logflare

1. Create a new source to populate the x-source header with the source UUID.
2. Use the api-key found in .docker.env and set it to x-api-key header
3. Set the otlp endpoint to http://localhost:50051
4. Start your OpenTelemetry instrumented app.

Limitations

• Only traces and metrics are currently supported.
