I wanted to integrate Elastic APM to some of the microservices in our company.

But I am not quite sure which configuration settings to go for.

Requirements:  
• Minimal storage required  
• Minimal bandwidth  
• Minimal memory usage

I read in **[Performance Tuning](https://www.elastic.co/guide/en/apm/agent/nodejs/master/performance-tuning.html)** section that setting sampling rate to 20% can help me to improve performance.

And, does the following need to included in every microservices?

> transactionSampleRate: 0.2

Is it the solution?  
And, I am afraid if any critical errors transactions are missed out in the process or not properly seen in distributed tracing.

Transaction sample rate set 0.2 means only 20% of transaction data will be stored.  
I cannot assume error transaction also will be sampled but if your transaction didn't raise error and result was success, they can be missed out.
