ELK Elasticsearch Review
Furnishes good end to end log monitoring, Logstash grok pattern capabilities


What is most valuable?

ELK provides 

  • good end to end log monitoring
  • Logstash grok pattern
  • elasticserach indexing
  • easily configurable Kibana dashboards
  • feature rich and appealing Kibana UI, as its USP.

How has it helped my organization?

The product offers a powerful, cost effective solution for proprietary log management and is easy to understand and start with. This saves cost as well as enhances usability.

What needs improvement?

The open source version should ship basic security versions with it. Alerting is an important feature which is not available in the open source stack.

For how long have I used the solution?

About two years.

What do I think about the stability of the solution?

Stability issues can be seen with Logstash and can be addressed using Kafka. Also, data collections may not be 100% optimal using Filebeat and could be further improved.

What do I think about the scalability of the solution?

The product is highly scalable, especially on the database side (elasticserach).

How is customer service and technical support?

Have worked on the open source version and, hence, I don't have much information about tech support.

Which solutions did we use previously?

I have not worked with another solution.

How was the initial setup?

The setup is straightforward for PoC, but becomes complex while scaling it or deploying it for production.

Which other solutions did I evaluate?

Yes, I evaluated GrayLog and Fluentd, but ELK was more feature rich.

What other advice do I have?

The ELK open source stack is rich in features but lacks the essential security features.

ELK is one of the best open source alternatives for log management. If alerting and security features can be built by the team internally, on top of the stack, then the product is for sure going to add a lot of value to business.

Disclosure: I am a real user, and this review is based on my own experience and opinions.
