We are very happy to report that we've successfully passed all of nearly 50,000 test suites of Jakarta EE 8 TCK, and Payara Server 5.193.1 is Jakarta EE 8 Full Profile compatible!
When running multiple instances of an application server, it is quite hard to see correlations between events. One of the best tools to enable that is the ELK stack - Elasticsearch for building fulltext index of the log entries, Logstash for managing the inflow the events, and Kibana as a user interface on top of that.
Solutions for Payara Server exist, that use better parseable log format which can be then processed by Logstash Filebeat in order to have these log entries processed by a remote Logstash server.
In our project, we chose a different path — we replaced all logging in the server and our applications with Logback, and make use of the
logback-logstash-appender to push the events directly to Logstash over a TCP socket. The appender uses LMAX disruptor internally to push the logs, so the processes does not block the application flow. This article will show you how to have this configured for your project as well.
