Radar Set Up

Overview​

With Multiplayer’s System Auto-Documentation functionality (Radar) you can automatically discover, track, and detect drift in your system architecture, dependencies and APIs by directly connecting to your infrastructure.

New to Multiplayer​

If you’re new to Multiplayer we recommend following this 2-minute set up:

  • Create a workspace, project, and team
  • Visualize your system architecture with a platform (import an existing diagram image or manually add your platform components)
  • Invite your team

For optimal results with Radar, we also recommend:

New to OpenTelemetry​

What is OpenTelemetry​

OpenTelemetry (OTel) is an observability framework and toolkit designed to create and manage telemetry data such as traces, metrics, and logs. It’s a vendor- and tool-agnostic, open source Cloud Native Computing Foundation (CNCF) project, born out of the need to standardize how to instrument code and send telemetry data to an observability backend.

Get Started with OpenTelemetry​

Instrumenting OTel in your application requires five minutes. Here are the steps:

  • Import the OpenTelemetry API and SDK
  • Configure the OpenTelemetry API
  • Configure the OpenTelemetry SDK
  • Create Telemetry Data

OTel provides language specific “getting started” guides for C++, .NET, Erlang/Elixir, Go, Java, JavaScript / Typescript, PHP, Python, Ruby, Rust, Swift, etc.

How the Multiplayer OpenTelemetry integration works​

Multiplayer Radar leverages the OpenTelemetry Collector, a proxy that receives, processes, and exports telemetry data to receive the traces data you export.

We store raw OTel traces in ClickHouse. After processing (i.e. extracting the component name, environments, dependencies, etc.), data is stored in a different database in ClickHouse.

Set up Radar​

If you’re new to Multiplayer or OpenTelemetry, be sure to follow those steps first. 👆

To set up Radar follow these steps:

  • Open your project
  • In the left-side menu, open “Radar”
  • Click “Set up Radar”
  • Customize your set up in the Radar dialog

Select your environment​

  • When selecting “Any” environment Radar will automatically detect the existing environments and collect data from them. This is a good option if you just want to try Radar and see what type of information it can display.
  • To select a specific environment from which you want Radar to pull information, you first need to add it in “Environments” on the left-side menu. Once you’ve added your desired environment(s), you can continue with the Radar set up.
  • If you want to set up a specific OTel token per environment, click “Add Environment”.

Add environment variables with the OTel token​

Your approach to implementing the Multiplayer OTel integration will be slightly different depending on how you use OTel.

Using OTel for a single observability backend (Multiplayer)

If you’ll be using OTel to send telemetry data to a single observability backend (Multiplayer), add these two environment variables:

OTEL_EXPORTER_OTLP_HEADERS="Authorization={{OpenTelemetry_Backend_Token}}

  • OTEL_EXPORTER_OTLP_TRACES_ENDPOINT - OTel Docs

OTEL_EXPORTER_OTLP_TRACES_ENDPOINT=https://api.multiplayer.app/v1/traces

  • OTEL_EXPORTER_OTLP_LOGS_ENDPOINT - OTel Docs

OTEL_EXPORTER_OTLP_LOGS_ENDPOINT=https://api.multiplayer.app/v1/logs

Using OTel for multiple observability backends

If you’ll be using OTel to send telemetry data to multiple observability backends, you would need to follow these steps.
