Automatic OpenTelemetry instrumentation for redis package version 2 and 3
@opentelemetry/instrumentation-redis is an npm package that provides automatic tracing and monitoring for Redis operations using the OpenTelemetry framework. It helps developers gain insights into the performance and behavior of their Redis interactions by capturing and exporting telemetry data.
Automatic Tracing
This feature allows you to automatically trace Redis operations. By registering the RedisInstrumentation with the OpenTelemetry tracer provider, all Redis commands will be traced and telemetry data will be collected.
const { NodeTracerProvider } = require('@opentelemetry/node');
const { registerInstrumentations } = require('@opentelemetry/instrumentation');
const { RedisInstrumentation } = require('@opentelemetry/instrumentation-redis');
const provider = new NodeTracerProvider();
provider.register();
registerInstrumentations({
instrumentations: [
new RedisInstrumentation(),
],
tracerProvider: provider,
});
Custom Span Attributes
This feature allows you to add custom attributes to the spans created for Redis operations. By using the responseHook option, you can capture additional information from the Redis response and add it to the span.
const { RedisInstrumentation } = require('@opentelemetry/instrumentation-redis');
const redisInstrumentation = new RedisInstrumentation({
responseHook: (span, cmdName, cmdArgs, response) => {
span.setAttribute('redis.response', response);
},
});
Error Handling
This feature allows you to handle errors in Redis operations and record them in the span. By checking if the response is an instance of Error, you can set the span status to indicate an error occurred.
const { RedisInstrumentation } = require('@opentelemetry/instrumentation-redis');
const redisInstrumentation = new RedisInstrumentation({
responseHook: (span, cmdName, cmdArgs, response) => {
if (response instanceof Error) {
span.setStatus({ code: 2, message: response.message });
}
},
});
The 'redis' package is a popular Redis client for Node.js. While it provides the basic functionality to interact with Redis, it does not offer built-in tracing or telemetry capabilities like @opentelemetry/instrumentation-redis. Developers would need to manually instrument their code to collect telemetry data.
The 'ioredis' package is another widely-used Redis client for Node.js, known for its support of advanced Redis features and high performance. Similar to the 'redis' package, it does not include automatic tracing or telemetry features. Developers would need to integrate it with OpenTelemetry manually to achieve similar functionality to @opentelemetry/instrumentation-redis.
This module provides automatic instrumentation for the redis@^2.6.0
module, which may be loaded using the @opentelemetry/sdk-trace-node
package and is included in the @opentelemetry/auto-instrumentations-node
bundle.
If total installation size is not constrained, it is recommended to use the @opentelemetry/auto-instrumentations-node
bundle with @opentelemetry/sdk-node for the most seamless instrumentation experience.
Compatible with OpenTelemetry JS API and SDK 1.0+
.
npm install --save @opentelemetry/instrumentation-redis
This package supports redis@^2.6.0
and redis@^3.0.0
For version redis@^4.0.0
, please use @opentelemetry/instrumentation-redis-4
OpenTelemetry Redis Instrumentation allows the user to automatically collect trace data and export them to the backend of choice, to give observability to distributed systems when working with redis.
To load a specific instrumentation (redis in this case), specify it in the registerInstrumentations' configuration
const { NodeTracerProvider } = require('@opentelemetry/sdk-trace-node');
const { RedisInstrumentation } = require('@opentelemetry/instrumentation-redis');
const { registerInstrumentations } = require('@opentelemetry/instrumentation');
const provider = new NodeTracerProvider();
provider.register();
registerInstrumentations({
instrumentations: [
new RedisInstrumentation(),
],
})
See examples/redis for a short example.
Redis instrumentation has a few options available to choose from. You can set the following:
Options | Type | Description |
---|---|---|
dbStatementSerializer | DbStatementSerializer (function) | Redis instrumentation will serialize the command to the db.statement attribute using the specified function. |
responseHook | RedisResponseCustomAttributeFunction (function) | Function for adding custom attributes on db response. Receives params: span, moduleVersion, cmdName, cmdArgs |
requireParentSpan | boolean | Require parent to create redis span, default when unset is false. |
db.statement
SerializerThe instrumentation serializes the command into a Span attribute called db.statement
. The standard serialization format attempts to be as informative as possible while avoiding the export of potentially sensitive data. The number of serialized arguments depends on the specific command, see the configuration
list in @opentelemetry/redis-common
.
It is also possible to define a custom serialization function. The function will receive the command name and arguments and must return a string.
Here is a simple example to serialize the command name and all command arguments. Notice that it might capture sensitive data and big payloads:
const { RedisInstrumentation } = require('@opentelemetry/instrumentation-redis');
const redisInstrumentation = new RedisInstrumentation({
dbStatementSerializer: function (cmdName, cmdArgs) {
return [cmdName, ...cmdArgs].join(" ");
},
});
