Update of Dynatrace communication endpoints
The domain used for internal communication by OneAgents and ActiveGates that send data to Dynatrace SaaS will be switched from *.live.ruxit.com to *.live.dynatrace.com beginning June 30, 2021.
This change will only affect Dynatrace SaaS customers, and only if you:
Use domain allowlisting on your outbound proxy, or
Use AWS PrivateLink to connect your OneAgents to Dynatrace
The OneAgent Java code module for z/OS now supports monitoring of the CICS Transaction Gateway and IMS SOAP Gateway. To download the OneAgent Java code module for z/OS:
In Dynatrace Hub, select OneAgent.
Select Set up > z/OS. Deployment via the Dynatrace FTP server is deprecated.
When upgrading the zDC to version 1.215, a special handling is required to avoid abends in CICS regions that you're monitoring.
Stop the zDC.
Wait for 15 minutes for the CICS module to reset and clean up the control blocks.
Update the zDC to the newer version.
Start the zDC.
