@infrastack/otel is a simple and easy-to-use open-source package which helps setting up OpenTelemetry tracing

⚡ Utilize this package to instrument your applications and get started with OpenTelemetry blazingly fast!

📦 Installation

$ npm install @infrastack/otel

Usage

To configure Infrastack SDK, call the init function in the instrumentation.ts:

import { Infrastack } from "@infrastack/otel";
Infrastack.init();

This will capture all the configurations from the .env file. This produces an output similar to below:

Exporter endpoint is set as: https://collector.infrastack.ai
Found an API Key: sk-1*****f5af
Service name is set as: fly-bright-dog
Service version is set as: 0.0.1
Application is now instrumented with infrastack.ai

Environment variables (.env)

INFRASTACK_LOGS_ENABLED=true/false # Enables or disables SDK startup logs
INFRASTACK_TAGS='[{"key": "key1", "value": "value1"}, {"key": "key2", "value": "value2"}]' # These tags are directly injected into ResourceAttributes of each span.
INFRASTACK_ENVIRONMENT=DEBUG/DEV/PROD 
INFRASTACK_API_KEY=YOUR_INFRASTACK_API_KEY

OTEL_EXPORTER_OTLP_ENDPOINT=YOUR_OTEL_EXPORTER_ENDPOINT
OTEL_EXPORTER_OTLP_HEADERS=YOUR_OTEL_EXPORTER_HEADERS # For infrastack.ai : "infrastack-api-key=sk-**********************"
OTEL_SERVICE_NAME=YOUR_SERVICE_NAME
OTEL_SERVICE_VERSION=YOUR_SERVICE_VERSION
OTEL_SERVICE_INSTANCE_ID=YOUR_SERVICE_INSTANCE_ID
OTEL_K8S_NAMESPACE=YOUR_K8S_POD_NAMESPACE
OTEL_K8S_POD_NAME=YOUR_K8S_POD_NAME

Initializing the SDK with configuration

You can initialize the SDK with configuration, which overrides the environment variables.

1. First, gather the related imports from @infrastack/otel in your instrumentation.ts

import { Infrastack, Instrumentation, Configuration, Environment, Tag } from "@infrastack/otel";

2. Then, set up your SDK options.

const myTags : Tag[] = [
    {key: "aws-region", value: "us-west-2"},
    {key: "aws-account-id", value: "123456789012"}
]

const configuration : Configuration = {
    serviceName: "my-cool-service",
    serviceVersion: "1.0.0",
    environment: Environment.DEV,
    tags: myTags,
    logsEnabled: false,
    podNamespace: "my-cluster",
    podName: "my-pod"
}

3. Initialize the Infrastack SDK

Infrastack.init(configuration);

Partial configuration is also possible. For example:

const configuration : Configuration = {
    logsEnabled:false
}
Infrastack.init(configuration);

This disables Infrastack SDK logs but collects the rest of the configuration from your .env file if available.

Custom spans

To produce manual spans in your code, you can seamlessly use the OpenTelemetry API:

import { trace } from "@opentelemetry/api";

const span = trace.getTracer("user-service").startSpan("fetch-user-data");
