In the rest of the blog I walk you through the steps that allows our teams to identify a “memory hungry” Jenkins plugin and how the removal of this no longer needed plugin resulted in an overall 3x improvement of Jenkins performance. As a negative side effect, the team ran into a JVM bug which they could workaround though.

Notebooks are a perfect tool to understand and perform an in-depth analysis of AWS AppFabric logs, thanks to the powerful Dynatrace query language, DQL. However, with Dynatrace Query Language (DQL) we can perform much more complex queries on our OCSF logs. This section shows how to analyze AWS AppFabric logs with Notebooks and DQL.
