4.5.9 Updates

Role-based Access Control for Business Journeys and Experience Level Management

- Application Analytics now enforces role-based access control (RBAC) for business journeys and experience level management (XLM). Upon rollout of RBAC, only the analytics administrator has access to business journeys and XLM. All other users see a warning in the controller UI stating that access is denied for any action or query within business journeys and XLM.
- The analytics administrator must grant permission on an individual basis to all users by creating new roles. Roles should include all applicable access for each user, both for business journeys and XLM. RBAC consists of three categories:
  - General - provides feature level access to business journeys and/or XLM. In addition to feature level access, search and event access are required to query, search, or create business journeys and XLM.
  - Searches - provides access to query data, which enables users to perform and save searches on business journey or XLM events.
  - Events - provides access to events type(s) and source(s). A user can only access the exact event type(s) and source(s) granted in the role. This is required in order to create a business journey or XLM definition or to access and create reports for particular sources.
- Business journey events cannot be accessed through the Custom Events API.
- No data is lost in the transition phase. RBAC restricts all users from accessing business journeys and XLM at the outset. However, if your analytics admin grants the exact access required for previously saved reports you will be able to access the report again as if the access had never been denied.

Language Agent Backward Compatibility

Starting in release 4.5, AppDynamics language agents are backward-compatible with any 4.4.1 or higher Controller. Thus you can upgrade your language agents – and take advantage of the latest agent-side enhancements, features, and bug fixes – without upgrading your 4.4 Controller. The following table outlines the Controller and language agent releases that are compatible.

Controller Release	Language Agent Release	Notes
4.4.1+	4.1+	4.4.1 and newer Controllers can accept connections from newer agents.
4.3.x	4.1.x – 4.3.x	4.3.x Controllers cannot accept connections from newer agents.
4.2.x	4.1.x – 4.2.x	Agents older than 4.3 are no longer supported, and agents older than 4.1 are no longer guaranteed to connect to a Controller.

Backward compatibility is supported on the following agents starting in Release 4.5:

Java
.NET
Node.js
PHP
Python
Go SDK
C/C++

Controller

You can now drill down into federation applications. This allows you to display incoming calls from the upstream federated application.
A new Create Events permission has been created.

Snapshot Waterfall Viewer

The Waterfall View within the snapshot viewer has been comprehensively enhanced. It now shows time spent in uninstrumented backend systems as well as inactive threads within instrumented nodes, and also shows the relationships between the segments. For asynchronous Business Transactions, it also labels the threads where the Business Transaction begins and ends.
