How to test performance of redis in AWS Elasticache?

Question

I want to test the Redis performance running in AWS ElastiCache. I have tried redis-benchmark tool to test it in my local machine. I need the same to test in ElastiCache but I believe there is no terminal access or redis-benchmark utility tool.

How can the redis-benchmark test be done for the redis in AWS ElastiCache?

Is there any other way to test the performance of the redis in ElastiCache?

Answer 1

Redis-benchmark tool is included on redis installation. What you may do is; connecting to your redis cluster from ec2. This tutorial shows the steps to connect it from your ec2 instance.

Then you may connect to your instance like this;

redis-cli -h mycachecluster.eaogs8.0001.usw2.cache.amazonaws.com -p 6379

Just like connecting to your cluster you may use

redis-benchmark -h mycachecluster.eaogs8.0001.usw2.cache.amazonaws.com -p 6379

to benchmark your cluster. It will print something like this;

====== mycachecluster.eaogs8.0001.usw2.cache.amazonaws.com ======
