Jira support

Devops - Nov 2020

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.

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.
