Depends very much what problem you’re trying to solve. The XPack machine learning is about anomaly detection

For search relevance, there’s the learning to rank plugin:

I have to perform log analysis and pattern finding.  
So I have output from elasticsearch with type of log(i.e. error,debug,exception).  
I want to detect cpu performance.

X-Pack's Machine Learning (not free) can assist with log analysis and metric analysis.

See the introduction of the product from Elastic{ON} 2017: [https://www.elastic.co/elasticon/conf/2017/sf/machine-learning-in-the-elastic-stack](https://www.elastic.co/elasticon/conf/2017/sf/machine-learning-in-the-elastic-stack)
