Send data from Loki to Axiom

Integrate Axiom in your existing Loki stack with minimal effort and without breaking any of your existing Loki workflows.

This page explains how to send data from Loki to Axiom.

Prerequisites

Configure the endpoint in Axiom

  1. Click Settings > Endpoints.
  2. Click New endpoint.
  3. Click Loki.
  4. Name the endpoint.
  5. Select the dataset where you want to send data.
  6. Copy the URL displayed for the newly created endpoint. This is the target URL where you send the data.

Configure Loki

In Loki, specify the following environment variables:

  • host or url is the target URL for the endpoint you have generated in Axiom by following the procedure above. For example, https://opbizplsf8klnw.ingress.axiom.co.
  • Optional: Use labels or tags to specify labels or tags for your app.

Examples

Send logs from Loki using JavaScript

const { createLogger, transports, format, } = require("winston");
const LokiTransport = require("winston-loki");

let logger;

const initializeLogger = () => {
  if (logger) {
    return;
  }

  logger = createLogger({
    transports: [
      new LokiTransport({
        host: "$LOKI_ENDPOINT_URL",
        labels: { app: "axiom-loki-endpoint" },
        json: true,
        format: format.json(),
        replaceTimestamp: true,
        onConnectionError: (err) => console.error(err),
      }),
      new transports.Console({
        format: format.combine(format.simple(), format.colorize()),
      }),
    ],
  });
};

initializeLogger()
logger.info("Starting app...");

Send logs from Loki using Python

import logging
import logging_loki

# Create a handler
handler = logging_loki.LokiHandler(
    url='$LOKI_ENDPOINT_URL',
    tags={'app': 'axiom-loki-py-endpoint'},
    version='1',
)

# Create a logger
logger = logging.getLogger('loki')

# Add the handler to the logger
logger.addHandler(handler)

# Log some messages
logger.info('Hello, world from Python!')
logger.warning('This is a warning')
logger.error('This is an error')
