APM UI - Customizing with Agent Builder data - "the Basics"

The IBM SmartCloud Application Performance Management UI (APM UI) provides a fast and simple interface into data provided by IBM Tivoli Monitoring (ITM).  It can be rendered on anything from a web browser to a smart phone.  As expected, it also provides customization capabilities.  In this post, we'll walk through end-to-end the process of introducing data/metrics from a custom ITM Agent Builder agent into the APM UI.

You're encouraged to take a look at this presentation by Cheng Quan Li of IBM Development which provides a nice overview of Dashboard Customization in APM UI.

Additionally, the documentation for APM UI customization (v. was the current version at the time of writing) can be found here.

For the purposes of this customization "basics", we're going to keep things very simple.  No fancy charts or graphs - we will simply display tabular data.  Our intent is to get comfortable with the process of customizing APM UI.  In later articles we may dig deeper into making your presentation more flashy.

We have a custom-built ITM Agent Builder agent (GBS Supermarket) for this exercise.  The data coming from this agent represents the check-out lanes at a typical supermarket.  Each lane has a name as well as performance data such as how many customers are waiting in line and the average customer wait time.

Here's what our agent looks like within the Tivoli Enterprise Portal Server (TEPS):

Launchpad - Unable to find supported browser

Recently while trying to install Netcool Omnibus 7.4 on CentOS 6.4, I ran into this problem:

I launched the Omnibus launchpad.sh script only to be told that the browser I was using was not supported:

"An error occurred while starting the launchpad. This error typically occurs when the launchpad is unable to find a supported browser. Check your product's documentation for a list of supported browsers."

But, the HTML file (noBrowser.html) was actually displayed by Firefox.  It turns out that the version of Launchpad only supports older versions of Firefox, namely ESR10.

There is a very simple fix to this issue:

1) Download an ESR10 version of Firefox, for example:

# cd /tmp
# wget https://ftp.mozilla.org/pub/mozilla.org/firefox/releases/10.0.2/linux-x86_64/en-US/firefox-10.0.2.tar.bz2

2) Extract it:

# cd /tmp
# tar -jxf firefox-10.0.2.tar.bz2

3) Tell Launchpad to use it

# export BROWSER=/tmp/firefox/firefox

4) Relaunch launchpad.sh

# /tmp/omni-install/launchpad.sh

and now it works:
