I need solution or guidance for below queries, to improve the performance. Kindly help.
- We can control logs in kibana, like log only if Error, is there any other way to do the same for logstash?
- Similarly Is it possible to deprecate index in run time, Like, i want to clear index data that are older than a week?
- Also my Elasticsearch data file is around 50Gb, is there any method to reduce the size other than deleting the index.
- There is only one node currently available, how to create more nodes and replicas? Do i need to run another elasticsearch instance in same machine?
