Logging in microservices

Question

assume we've got a number of Web API microservices, and they are written in different languages/framworks (some are ASP.NET Web API, some are NodeJS, some are Flask etc.).

I would like to log every request made to any service, and I would prefer a centralized log.

What method/tools should I use?

Answer 1

There is a very famous approach called ELK:

• Elasticsearch: Search and analyse data in real time
• Logstash: Collect, parse and enrich data from each machine
• Kibana: Explore and visualise your data graphically

So all the information is collected by Logstash, stored in Elasticsearch and visualised using Kibana UI.

With this stack no matters who is generating the information (or what technology is using).
