Java Modules support

Java modules were introduced in Java 9.

The JZR report of your Java application exposes now its loaded modules and their module graph dependency.
Jeyzer Monitor introduces a new set of monitoring rules to check the Java module names and versions : still time to detect any snapshot or beta version of a Java module in your production application.
Those module checks are also available in the JZR report, along with the other detected events.

The Jeyzer Recorder agent is required to capture the Java module information from the target application.

Jira support

Jeyzer 2.1 integrates with Jira Cloud.

Whenever a critical incident happens in your production or QA environment on a Java server, Jeyzer Monitor will automatically create a Jira ticket in the right project and attach all the details of the incident, including the JZR report.
If the Jira ticket exists for such incident, Jeyzer Monitor will update it with a comment and attach the JZR report if required.

Advantages :
The Jeyzer integration with Jira brings a better and strong reactivity.
Your teams will start processing the incident directly from Jira.
Also administrative work time is saved, removing those questions : which project? who is responsible?…
At last, benefit right away from the Jira notification mechanism : ticket could go directly to the right R&D team for example.
