Additional Information and Software and Hardware Requirements
1. PureStack Technology: Reveals System Health Impact On Application Performance
This newest release introduces PureStack - the only solution that provides complete visibility not only across and deep into application components but also into the infrastructure components your applications are running on. It's now possible to immediately see if an unhealthy system or a runtime issue affects your applications' performance.
Even if you are monitoring thousands of nodes, you will now know faster than ever when and where something goes wrong and can immediately identify the root cause for issues instead of searching through system logs!
The all new Infrastructure view is an entry point for Operations that needs to:
- monitor a large number of hosts or instances in a single screen
- identify the impact of infrastructure problems on applications and critical processes
It's uniqueness to bring together infrastructure health and application impact by fully integrating the workflow of problem isolation can shorten the communication between application owners and system operators.
It's now easy to look at the whole environment starting with two different view points:
- The improved Application Overview starts with an application centric perspective-- PureStack Technology discovers all infrastructure components and provides the ability to monitor their health and drill into any detail.
- The new Infrastructure Overview starts with an infrastructure centric perspective – PureStack Technology allows operations to find every single user request, business transaction or application that is affected by an infrastructure component and as a result understand the application impact of an infrastructure issue.
Host and Process Health Dashboards
Following the workflow from the infrastructure overview you will also find improvements on the single host monitoring or process view, including:
- new visualization for historic health indicators of different aspects
- I/O rate charts for individual disks
- specific Web server monitoring Dashboards for Apache and IIS (7+)
Application Overview Dashboards
The Application Overview Dashboards have been improved and extended to include vital information captured by PureStack Technology where needed. As an application owner there is no more asking system operators if everything is operating within healthy boundaries. You will immediately see if something is wrong on the infrastructure level and the effect on those applications that depend on it.
- mapping process and host health to individual transactions and business transactions
Transaction Flow Improvements
The Transaction Flow has been redesigned to be cleaner and leaner!
- No more toggling and switching views for transactional or health states, it's all in one visualization now: process and host health as well as transactional errors
- New adaptive zoom levels that focus on the really relevant information.
- New fit-to-screen switch to get a good overview even of the biggest environment.
2. PurePath Technology and User Experience Management for PHP Applications
Compuware is proud to announce that the PurePath Technology is now available for PHP providing full code-level visibility into all your PHP applications and services. In combination with User Experience Management this gives you complete end-to-end visibility into PHP based web-applications:
dynaTrace provides deep visibility into each PHP tier without the need to configure any sensors - the tried and tested AutoSensor technology ensures zero-configuration results, even if you know nothing about the application. No more endlessly trying to decipher legacy PHP code - see what happens at run-time, pinpoint the problem and fix it.
The out-of-the-box Sensor Pack for MySQL (including support for MySQL Extension, PDO and mysqli) reveals all the database usage within your application - providing the ability to analyze database statements and their performance impact with the already familiar Database Dashlet.
With specialized support for the PHP extension cURL dynaTrace connects cross-tier and cross-technology transactions revealing the communication architecture and giving you a full understanding of component and service dependencies - even to third party services. To get visibility into arguments and return values simply place a sensor at any function and for the next function-call dynaTrace will automatically capture the data - no restart or redeployment needed. Full visibility into Exceptions makes finding functional problems effective and fast by pinpointing the source of the Exception with the full call-stack information - for all Exceptions, whether they are logged or not.
In addition to the well known execution time and CPU time metrics, dynaTrace also tracks the compilation time of each PHP function call - an often overlooked cause of performance and scalability problems. Altogether this solution gives you unprecedented visibility into PHP execution and is fully production ready with extremely low overhead.
3. UEM for Web and Mobile Applications
Native mobile apps are an increasingly important part of commercial online offerings and tracking their user experience is key to making sure the investment in app development is fully leveraged. To give Operators the complete picture of your end user experience dynaTrace has now seamlessly integrated the information from mobile apps into the UEM views, combining Page Actions and Mobile Actions into User Actions - it is all about the users after all.
Mobile App ADK
With the multitude of different devices and operating system versions it is essential to track user experience and errors for all real users. With the greatly improved lifecycle-aware Mobile ADK now optimized for multi-threaded applications this has become easier than ever - just use the dynaTrace base classes for your application lifecycle and you immediately get User Actions and visits for all your users. The Mobile ADK now automatically transmits crash reports for iOS and Android (except for IIS6) to dynaTrace giving your app developers full insight into the line of code that triggered the crash along with the entire visit to see what exactly the user did before the crash. Additionally the new error reporting capabilities allow app developers to send custom errors along with root cause information to dynaTrace. These new mobile errors are also fully integrated into the error detection capabilities of dynaTrace.
Of course, the new version of dynaTrace is still fully compatible with the 5.0 Mobile ADK - your app users can upgrade at their own convenience.
General UEM Improvements
Conversion rates are the most important metric for the success of an online offering. In order to support complex scenarios where users have different options (like buying a product or just signing up for a newsletter) dynaTrace has now introduced multiple conversion goals per application. This greatly improves the out-of-the-box analytic capabilities and allows you to show different types of conversions in the same chart - making sure your reports are complete and understandable. To give you more fine grained information about your user base, dynaTrace 5.5 now provides user locations on a city granularity allowing you to analyze different user behavior based on local preferences or just comparing the success of local marketing campaigns.
The Visits view has also been improved to show the user experience per browser type or mobile device type. Additionally the Visits view now supports advanced filtering for easy and detailed visit analysis.
With the all new UEM Key Metrics Dashboard all the analytic capabilities are easily available from the Start Center. The overhauled User Experience Settings in the System Profile Configuration have also been completely reworked to make sure the configuration is clear and self explanatory.
Join the Early Access Program for WebSocket Support
WebSocket is a new capability of browsers and Web Servers that allows for even more complex and responsive Web user interfaces. By downloading and using the experimental version of the dynaTrace WebSocket Plugin you will get full visibility into how WebSocket is used in your application and how it affects the user experience.
4. Cloud and Big Data Analytics
With our new version we approach Big Data from two different angles, with the Big Data Exporter we enable customers to stream Business Transaction Data to external systems in real time to manage the data on an independent Big Data Solution or integrate it with your own Business Intelligence tools. It works for any Business Transaction, be it Visit, Client Action or Server Side Transaction, so you can export them to your own Hadoop cluster or a more traditional data warehouse.
Also, we extend our support for other Big Data technologies, namely MongoDB and HBase which allows you to analyze how your NoSQL database contributes to your applications response time, how often you call it and which statements are executed in a specific transaction.
With our enhanced Hadoop Sensor we can now also show critical information such as the ID and the specific name of the Hadoop jobs that are running, making it even easier to optimize your Hadoop cluster´s performance.
5. New Enterprise Tiers for PurePath for z/OS
CICS Transaction Gateway (CTG)
Compuware is proud to announce the support of the CICS Transaction Gateway for z/OS. Now it's possible to trace transactions from a Java client through a CICS Transaction Gateway into a CICS Transaction Server. The CICS Transaction Gateway may run either in a distributed environment or directly on z/OS.
CICS Web Services via SOAP
A CICS Transaction Server application can participate in a heterogeneous web services environment as a service requester, as a service provider, or both. The experimental SOAP Sensor of the 5.0 release is now a fully functional and supported Sensor within the CICS Agent, which gives you complete end-to-end visibility for incoming and outgoing HTTP calls!
CICS Tagging Agent Development Kit (ADK)
The CICS Tagging ADK extends the capability of the Compuware APM solution to areas and scenarios which are not supported by default sensors. If there is a custom, proprietary protocol, for example based on CICS IP Sockets, it can be easily addressed with the new CICS Tagging ADK. Thus it enables the ability to trace transactions across different platforms, different technology types and correlates the parts of the transaction from different tiers into one single PurePath!
The only thing you have to do is insert the tagging API calls in a central place in your CICS program.
The CICS ADK consists of the following API calls:
- Start Path
- Start Linked Path
- End path
- Insert Link
- Insert Async Link
E. g. start a CICS PurePath that is a continuation of another PurePath, typically in response to an inbound service request from another platform.
CALL "DTSLPA" USING BINARYTAG, LENGTH RETURNING RC.
CALL "DTSCLPA" USING CUSTOMTAG, LENGTH RETURNING RC.
CALL "DTSLPTF" USING FIXED_LEN_STRING, LENGTH RETURNING RC.
rc = DTSLPA(binarytag, length);
rc = DTSCLPA(customtag, length);
rc = DTSLPTN(c_string);
rc = DTSLPTP(pli_string);
rc = DTSLPTF(fixed_len_string, length);

6. Streaming Support
To get an overview of how media streams affect your end user experience just go to the Start-Center and open the out-of-the-box Dashboard for Streaming Media or just have a look at the visits Dashlet to see how your users are navigating to the media. And for deep dive diagnostics you can get all key metrics for every video or audio stream consumed by your users.
7. Lifecycle and Agile
dynaTrace now automatically recognizes different categories of tests and only alerts on violations of metrics that are relevant for a test category. This way fluctuations in execution time of e.g. a Unit Test will not lead to alerts. This enables you to perform architecture validation on all your unit tests and only track performance for those tests that are performance critical. There is also a category for Load Tests which makes it easy to organize all your test results in one place and compare them to get the full picture of your system performance from unit tests to the full scale performance and scalability load tests.
8. Ease of Use
With dynaTrace 5.5 we have further focused on ease of use in our workflow based Dashboards. Enabled by PureStack Technology these provide a seamless integration between an application-centric view and the infrastructure level that focuses on the health of underlying operating system instances and runtime health. It is easier to navigate back and forth and between these tiers and to find the right information where it is needed.
Among those improvements you will find:
- Ability to define favorites for applications and individual business transactions
- Separate and actionable health indicators for process and host health
- Quick filters for displaying critical or healthy applications and transactions
- Ability to use baselining charts on custom Dashboards
9. New Technology Support
dynaTrace 5.5 adds support for new technologies including:
- Servlet 3.0
- EJB 3
- IIS 8
- Apache HBase
- IBM HTTP Server 8.0, 8.5
- JBoss AS6 and AS7
- Interstage 8
- Cosminexus 8
- Glassfish 3.1 Open Source Edition
- CICS Transaction Server 3.2, 5.1
- CICS Transaction Gateway 8.0, 8.1, 9.0
- CICS SOAP over HTTP
10. Integration with the APM Product Family
dynaTrace 5.5 offers the possibility to integrate with the Gomez APM Portal. If the integration is activated, some aggregated overview UEM data will be sent to the Gomez APM Portal where you can then easily compare it with your synthetic monitoring data.
This integration enables also direct drill downs from your synthetic test to dynaTrace to see the root cause of a slow or failing tests with a single click.
- Enables a first overview of the application in the APM Portal to compare it with your synthetic test.
- Synthetic tests will be automatically tagged to identify the test name and test step within dynaTrace and populate the out-of-the-box Synthetic Monitoring Dashboard.
- Activates different drill-downs in the APM Portal to immediately switch to the dynaTrace client for more use cases and deeper understanding what's going on.
Additional Improvements and Changes
Apart from the major enhancements described above there have been dozens of other enhancements that make dynaTrace easier to use and more productive in many different areas. Here are the most important improvements:
Database Statement Aggregation for JDBC and ADO.Net
By turning on "Statement Aggregation" in the JDBC/ADO.NET Sensor properties, PurePaths now contain an aggregated summary for database statements. This significantly reduces the communication between Agents and Server and the overall length of PurePaths thus providing an overhead reduction for these sensors. We highly recommend to turn this setting on for production environments or if you have long PurePaths due to database statements. For newly created system profiles this will be turned on by default.
New Analysis Dashlet: Database Hotspots
Up to now it was sometimes quite tedious to get a good idea which transaction types where calling a specific database statement and where those exactly were called from. By introducing the new Database Hotspots view it's now possible to get a aggregated view "back up" from the statement to the individual Web request and it's execution path.
Auditing of System Changes
For compliance requirements all changes performed by users will now be logged to an audit log stored on the dynaTrace Server. Additionally save-points for system profiles will be created automatically.
Remote Restart of Host Agents
It's now possible to restart (and thus update) Host Agents from within the dynaTrace Client Agent Overview. Just select the Host Agents you need to restart and select the restart option from the context menu.
- dynaTrace Server throughput improved by approx. 10%
