During an issue, logging on to each node and checking its logs is tiresome. Instead, we can use a logging stack or a built, custom logging stack with tools available based on our use case. The following stack is a subset of the Elasticsearch, Logstash, Kibana (ELK) stack. We wouldn't require a complex aggregation of logs across nodes, so logstash can be eliminated and we can use a simple Filebeat for log-forwarding, Elasticsearch for storage and querying, and Kibana for visualization and filtering. Moreover, this entire stack can be integrated with any application stack and all the logs across stacks can be visualized on a centralized backend with a single frontend along with all open source community tools. This wouldn't require a license as this logging stack is more of a replacement for a proprietary log aggregator:
