The numbers tell the tale! By aggregating log files in an easy to use tool, where you can easily zoom in into problems, you get a clear view on what improvements can be done to increase the stability and performance of your instance. Joachim Bollen, an Atlassian expert with a long-time focus on performance and stability, will guide you through the setup and configuration of Elasticsearch, Logstash, and Kibana (ELK) to aggregate the logging and metrics of your Atlassian applications (Jira, Confluence, and Bitbucket). He will show you how this setup helped in detecting the root cause of performance issues in Jira and how dashboards can help you monitor the health of your Atlassian applications.
