A. What is Browser EUM And How Does It work?
B. Instrumenting Browser RUM
C. Browser RUM Metrics
Agenda

What Is Browser RUM?
You can drill into the data to explore how
users experience your application in their
web browsers and answer questions like
Which clientside resource calls
are slowing down page load time?
How does server performance impactend user
experience in aggregate or in individual cases?
See how your web application is performing from the point of view of an end user

What Are The Benefits Of Browser RUM?
Reduce MTTR
• Quickly resolve web
performance bottlenecks
with end-to-end visibility
• Drill down into individual
user experience to respond
quickly and resolve web
app/site performance issues
Understand Your Users
• Understand End User
web experiences
and sessions across
the globe,in real-time
• Get browser-user insights
to optimize web experiences
Know How Your App
Is Being Used
• Track user sessions
in real-time to understand
and improve the business
impact of browser
performance on your KPIs

Overview Of How Browser RUM Works
AppDynamics manages the EUM cloud for SaaS implementations,
however you can host your own EUM cloud
adrum.js
is injected in
each browser
page,near
the top.
adrum.js starts
timer, configures
and asynchronously
downloads adrum-ext.js.
adrum-ext.js does most
of the work.
The agent
watches the
browser for
certain signals
and times them.
Data is uploaded
to the EUM cloud and
processed into a smaller
dataset for quick access.
Raw data is also stored
and can be accessed by
AppDynamics.It is stored
in the Events Service.
The controller
downloads the
data and you
have access.

Agenda

JavaScript Injection Options
There are five options to inject the adrum.js JavaScript into your code
1. Manual Injection
Download adrum.js and add it to the script tags within the head tags
of your application.
2. Container Assisted Injection
Nginx and Apache users can use the substitution features offered by
container extensions to auto-injectthe agentinto pages.
3. Automatic Injection
Uses AppD server-side agents to automatically add the adrum header
and footer to each of your web pages.
4. Assisted Injection JAVA ONLY
Targets specific Java classes and methods that return html for rewrite to
include adrum.js.
5. Assisted Injection ATTRIBUTE INJECTION
Manually provide hints in the page templates of specific app frameworks
that the server agentcan use to injectadrum.js.
MOST
COMMON

Manual Injection Overview & Configuration
3. Scroll sidebar down and select
Configuration.
4. Select Web JavaScript
Instrumentation tab.
5. Save the JavaScript agent at the
path below. Save it as adrum.js.
6. Add script tags within your head
tag, as close to the top of page as
possible after meta tags.
The EUM JavaScript agent is downloaded from your AppDynamics environment,
and the code is inserted into the head tags of your application
<!—Sample Script--><head>
<script>window['adrum-start-time'] =
new Date().getTime();</script>
<script src="/adrum.js"></script>
...
</head>

Lab 2
Know Your Browser Users
Scenario
Your manager has asked you to determine the top
countries accessing your app, and identify countries
with the most issues.This way, your team can develop
a plan to resolve issues in top priority regions.
Your manager has also asked you to determine what
devices,browser, and browser versions are being
used the most, so that your team can ensure that
these resources are closed monitored and issues
related to them can be resolved quickly.
Finally,the UX team is interested in knowing the pages
being requested the most so they can optimize the
user experience for these pages.

Lab 3
Troubleshoot With Pages & AJAX Requests And Analyze
Scenario A
You were notified that a particular page in your
application is performing slowly.You would like to
check how the frontend of the page is performing,
to see if the issue is related to frontend resources.
If the backend is causing the lag, you would like to
navigate to troubleshootthe problem using
AppDynamics APM.
Scenario B
You would like to see what pages had browser
transactions with the very slowestresponse times.
You would then like to filter performance data by one
of the pages, and look for browser snapshots with
correlating backend transaction snapshots.Using
this information,you can troubleshootthe slow
transactions on both the frontend and the backend.

What Is A Browser Session?
A browser session tracks an individual user’s journey using page loads,
virtual page loads, iFrames, and Ajax requests (if customers opt in).
In this example,a session might capture the session data involved in a user
logging in (start), selecting and paying for products, and logging out(end).
This is an example e-commerce session:
09:30:04.01 to
09:30:07.50
09:30:10.05 to
09:30:10.50

Know How Your Browser App Is Being Used
Scenario A
The product team would like to know how many
users abandon the app after visiting a single page.
Scenario B
The UX department is interested in optimizing the
experience of using the browser app on mobile and
tablet devices. It is only necessary to access three
pages to complete a purchase. The team would like
to know what percent of users take more than three
pages to complete a purchase. They would also like
to know which pages are visited.

What Is Browser Synthetic Monitoring?
Geographically distributed agents monitor Browser Synthetic Transactions
Browser synthetic monitoring allows you
to monitor the performance and availability
of critical pages independently ofuser
generated load.
It can help with troubleshooting
and measuring SLA compliance.
Synthetic agents are currently delivered
as a SaaS service only. SaaS customers
can immediately getaccess to Browser

A. What is Mobile RUM and how does it work?
B. Instrumenting Mobile RUM
C. Mobile RUM Metrics
Agenda

What Is Mobile RUM?
Mobile RUM allows you to understand your
native iOS or Android mobile application as
your end users actually use it. It provides
you with visibility into the functioning of the
application itselfand the application's
interactions with the network it uses and
any server-side applications itmay talk to.
You can answer questions like:
How many crashes have there been
in a certain region?
Which network requests are the slowest?

What Are The Benefits Of Browser RUM?
Reduce MTTR
• Get deep code level visibility
to identify and resolve crashes
and errors quickly and
efficiently.
• With AppDynamics APM,
discover business transactions
to provide mobile application
to back-end application
dependencies.
Understand Your Users
• Get accurate user insights
and visibility into every
user and their mobile
application activity.
• Get detailed visibility into
all network requests from
your mobile app.
Know How Your App
Is Being Used
• Track mobile user sessions
in real-time to understand
and improve the business
impact of your mobile apps
performance on your KPIs.

Overview Of How Mobile RUM Works
adrum.js starts
timer, configures
and asynchronously
downloads adrum-ext.js.
adrum-ext.js does most
of the work.
The agent
watches the
app for certain
signals and
times them.
Metrics are uploaded to the EUM
cloud and processed into a
smaller dataset.
Raw data is also stored and can
be accessed by AppDynamics.It
is stored in the Events Service.
The controller
downloads the
data and you
have access.

Agenda

Instrumenting Mobile RUM
To use Mobile RUM you add a small piece of highly
performantcode (i.e., the mobile agent) to the source
of your mobile application.
For iOS, the mobile agentis Objective-C code.
For Android,the mobile agentis Java code.
Metrics collected are similar to those collected for browser RUM with some differences

Several Ways To Instrument A Mobile Application
CocoaPods
Manual
Gradle
Maven
Ant
Manual
You will need to upload a dSYM (iOS) or ProGuard
(Android) file to ensure that your crash reports are
human readable.Normally you upload the file at the
time that you instrumentyour mobile application.

Know Your Mobile Users
Scenario
Your manager has asked you to determine what
mobile devices,mobile OS versions,and other
mobile resources are being used the most, so
that your team can ensure these resources are
closely monitored and issues related to them
can be resolved quickly.
Your manager has also asked you to determine
the top countries accessing your app, and
identify countries with the most issues. This
way, your team can develop a plan to resolve
issues in top priority regions.
