HPE Performance Center 12.50 New Features Webinar
Questions and Answers
December 17, 2015
Q: Is there a specific format for the logs?
A: PAL uses production logs with cookies and user details.
Q: What’s the size of the logs?
A: The log size is unlimited, but it is recommend to take up to 1 peak hour to
reduce the processing time.
Q: Is the test scenario created automatically? Can it be customized?
A: Yes , in the Scenario tab click “Create Test”. PAL creates a test which can be
customized.
Q: How can we be sure that the load test represent the real load and to compare
its results to production data?
A: After you run the test, you can create a PAL report that compares between the
production log and the results. The comparison report can be displayed as a grid
or as a chart.
Q: Do I need an extra license to use PAL + NV?
A: PAL – no additional license is required, NV - you get license for 2 free Vusers.
Q: Can we generate the NV analytics report during the load test?
A: We have heard that feedback from the field and intend to add this capability in
a future release.
Q: Is there a particular license proposed for noise generator? I assume this
capability is limited to Web apps, right?
A: No need for a specific license to use noise generator scripts.
When working with noise generator scripts, the total number of charged Vusers is
as follows:
10 noise Vusers are charged as a single Vuser.
100 noise Vusers are charged as 10 Vusers.
It is relevant for Web apps. The purpose is to create a load on the server by
having a large number of users accessing the same URL simultaneously.
Q: Google Analytics and Web trends data are no more supported by PAL for now,
right?
A: In PC 12.50, PAL supports logs that include user cookies/sessions (such as IIS,
Apache and HP RUM). PAL analyzes the logs and automatically creates business
flows and performance scenarios.
You can also use Google Analytics and Webtrends logs to create PAL compression
reports.
Q; what stands PAL for?
A: Performance Application Lifecycle. The improved PAL feature allows for
complete end-to-end testing and DevOps feedback. Users can accurately compare
performance test results with real production data benchmarks. Analysis of these
results provides a framework to assist you in creating performance test scenarios
to resemble realistic environments as closely as possible, which reduces test
assumptions and risks.
Q: What Versions of FF, Chromium und IE are supported/delivered?
A: The following browsers are supported:
• Microsoft Internet Explorer 9, 10, 11 (On Microsoft Windows only)
• Google Chrome 44.x (On Microsoft Windows only)
• Mozilla Firefox 39.x (On Microsoft Windows only)
• Apple Safari 7.x (On Mac OS only)

Q: How do I Enter Login-Data for my website?
A:Not clear, please add more details.
Q: Can explain network virtualization in more detail?
A: Network Virtualization software enables you to capture and emulate real-world
network conditions to use in your performance tests, and analyze test results to
detect and repair performance bottlenecks before deployment. For more
information: Network Virtualization Overview ( http://almhelp.saas.hp.com/en/12.50/online_help/Content/PC/c_wan_emulation_overview
.htm)
Q: can you please provide us full list of protocols that NV support in PC 12.50?
A: In PC 12.50 NV supports all protocols including Java and Citrix.
Q: Need reconfirmation - will automated script creation handle dynamic values?
A: One of the algorithm steps in PAL is to find repetitive patterns. A repetitive
pattern is marked as a parameter.
Q: Will the NV profile will be only visible inside the project? Or can it be shared
with the entire farm?
A: In PC we can import locations data between tests within the same projects.
Currently we do not have the option to copy the profiles between projects. We
will consider this capability in future versions.
Q: Presenter and Chart showed PAL only supports IIS, Apache and HP RM. When it
started also shows Google Analytics and Web trends. So what is really supported,
and can we use Google Analytics?
A: In PC 12.50, PAL supports logs that include user cookies/sessions (such as IIS,
Apache and HP RUM). PAL analyzes the logs and automatically creates business
flows and performance scenarios.
You can also use Google Analytics and Webtrends logs to create PAL compression
reports.
Q: So as per the ratings shown just now, different actions within a script can have
different impact on the performance based on the network?
A: Slower networks may have significant impact on both client and server
performance. The NV Analytics report provides a set of recommendations to help
improve application performance even on the slower networks.
Q: Do we have Production log feature in Loadrunner 12.5?
A: No, we don’t have this option in LoadRunner 12.50.
Q: Does it matter, that you’re using chrome browser?
A: The following browsers are supported:
• Microsoft Internet Explorer 9, 10, 11 (On Microsoft Windows only)
• Google Chrome 44.x (On Microsoft Windows only)
• Mozilla Firefox 39.x (On Microsoft Windows only)
• Apple Safari 7.x (On Mac OS only)

Q: How does pal deal with reverse proxy and balanced systems?
A: PAL works with one server log at a time. You cannot combine logs from two
different servers.
When working with balanced systems, you can select a single server and use its
log, if it contains all your business flows.
Q: do we get access to load generators for installation of our application when
using RDP Protocol?
A: Load generators are available through RDP
Q: When PC 12.50 is transferred to SAAS, will PAL be integral to the SAAS cost or
separate?
A: PAL does not require any additional licenses (on premise or SaaS). Once SaaS
on boards 12.50, users will be able to use the 12.50 features based on their
agreements with SaaS.
Q: For input to PAL, do we need to provide the logs for Web server only OR web
server + App server?
A: You need to provide Web server logs only.
Q: what exactly the Noise Generator scripts?
A: It's an URL , to be accessed simultaneously by vast number of Virtual Users to
create a load on the server application. It can be used in parallel to complex
business flows to simulate stress conditions.
Q: Will java script feature in Web/HTTP will help in some side of client side testing
or option for Ajax Click and script?
A: What do you mean by client side testing? Please elaborate.
Q: Will NV Analytics give me the response times for resources present on Akamai?
A: NV Analytics displays detailed information for any resource downloaded by the
application, including information about its source and a detailed timeline
breakdown. If resources are downloaded from Akamai, NV Analytics will provide
information on response times.
Q: How do you remove licenses in PC 12.5?
A: You cannot remove licenses.
Q: How to Navigate from one project to another without opening the new session
or logout?
A: You have to log out from the current Performance Center project and log in to
another project.
Q: What's is the value provided by the noise test? What’s the benefit of use it?
A: Noise generator's purpose is to create a load on the server by having a large
number of users accessing the same URL simultaneously.
Q: How are the NV recommendations determined? I.e. how are the set of rules
defined? By who?
A: NV validates the application using a list of rules. Each rule is assigned a severity,
which is reflected in the calculation of the overall grade. Some of the rules are
based on common best practices, found also in YSlow. Others are unique rules
based on our own research.
Q: Can you now simulate 1000's of Virtual clients with True Client? How many TC
VU can you run on a quad processor with 16 GB machine for example?
A: You can run 20,000 TruClient Vusers. It depends on how many load generators
are in use. Some of our customers run thousands of TruClient Vusers with
StormRunner. It is hard to determine how many Vusers you can run on a given
machine since it may vary between different applications. A quad processor with
16 GB RAM machine, is unable to run a large number of Vusers. As for memory, it
may limit to a maximum of 80 Vusers, but the processor might be saturated
earlier.
Q: Does the new PC 12.50 support scripting on Edge?
A: PC 12.50 does not support scripting on Edge.
Q: Does PAL script generation support Siebel OpenUI with iPlanet web servers?
A: PAL generates Web-HTTP template scripts.
Q: Does Network Virtualization license server needs to be installed on a different
machine or can it coexist with Perf Center machines?
A: The NV license server is not required for the NV integration with PC 12.50. The
Network Virtualization license is managed from the Lab Management - PC licenses
page, together with all PC licenses.
Q: Does TruClient 12.50 support IE11?
A: TruClient supports IE11. For details on browser support for additional
protocols, see https://softwaresupport.hp.com/group/softwaresupport/searchresult/-/facetsearch/document/KM01766777
Q: Can you advise, if smaller countries or cities are not listed in global library of
SHUNRA network Virtualization?
A: The Network Virtualization Global Library contains a large database of real,
worldwide network information. It enables you to emulate networks in your lab,
based on actual measurements.
The Global Library contains a vast number of countries and cities and is
periodically updated. If you require information about specific cities not currently
included in the Global Library, please contact us. We may be able to add the
information you need.
Q: Can we get the concurrent usage information from Usage report?
A: Planned for an upcoming release.
Q: Is PAL available on Performance center v12.21?
A: Yes, however unlike in PC 12.50, PAL in PC12.21 does not analyze the
production log and create a PAL scenario with business flows automatically.
In PC 12.21, you can create comparison PAL reports from the production logs.
Q: The LeanFT script can run only 1 vuser per LG, correct? Or can we run multiple
LeanFT Vusers on the same LG?
A: The LeanFT script can run only 1 Vuser per LG
Q: Is JSON playback visualization in 12.50 VUGen?
A: In VuGen 12.50, responses with JSON body are displayed in a dedicated JSON
viewer (similar to XML viewer). Additionally, VuGen 12.50 has the option to create
correlation on JSON snapshot using JPath queries.
Q: Is there limitation on the version of IE supported by PAL?
A: No, PAL works with server logs without any relation to the user client.
Q: Will Vugen 12.50 will support VB scripts?

Siebel web, Web (HTTP/HTML), IMAP, POP3, SMTP, ODBC, Oracle -2 Tier, C Vuser,
FTP, DNS, LDAP)
Q: Does it support the web services? Testing?
A: Web services are supported.
Q: does the memory foot print for truclient enhanced in 12.50? And what is the
overall improvement on truclient protocol? Object recognition and so on...
A: TruClient memory footprint has been improved in 12.50, but it is still higher
than the Web transport protocol footprint.
TruClient now supports 3 main browsers (IE, FF, Chromium) and consolidates
them under the “TruClient Web” protocol (where you can record in one browser
and replay in another). For additional updates and improvements, see the
TruClient documentation.
Q: What enhancement do we have on 12.50 for web protocol? Does the
correlation get better?
