RedisQueueDepthMetricPublisher

A construct that creates an AWS Lambda function to publish queue depths from a redis instance

Usage

To use the RedisQueueDepthMetricPublisher construct, simply import it into your AWS CDK stack and create a new instance of the construct:

import { Stack } from 'aws-cdk-lib';
import { RedisQueueDepthMetricPublisher } from './cdk-redis-queue-depth-metric-publisher';

let stack: Stack;

new RedisQueueDepthMetricPublisher(stack, 'RedisQueueDepthMetricPublisher', {
  cwNamespace: 'example',
  cloudwatchLogsRetention: RetentionDays.THREE_MONTHS,
  publishFrequency: Duration.minutes(5),
  queues: ['fakeQueue', 'fakeQueue2'],
  redisAddr: 'fakeRedisAddr',
  // redisPort: '123456', // Optional
  redisSecretArn: 'fakeRedisSecretArn',
  redisSecretKeyArn: 'fakeRedisSecretKeyArn',
  // redisSecretPasswordPath: 'fakeRedisSecretPasswordPath',
  // redisSecretUsernamePath: 'fakeRedisSecretUsernamePath',
});

This will create a new AWS Lambda function that publishes queue depth metrics to CloudWatch every 5 minutes. It pulls the information from the fakeRedisAddr redis instance on the default port. It will fetch login credentials from redisSecretArn, log into the redis instance and query the two queues ['fakeQueue', 'fakeQueue2'], then publish the info to the cwNamespace with metric names that are identical to the queue names. NOTE: no mapping is currently supported for the queue names.
