In correlation with the fast paced technological evolution, software applications have also evolved to become more complex, more distributed and more dynamic. Cloud computing has pushed this evolution a step further. Therefore it is now more difficult to properly monitor application performances and ensure the end user that he will get the high-quality experience he is expecting. Luckily great tools such as InspectIT APM are taking care of the problem efficiently. In this presentation I will introduce you to inspectIt APM and then I will show you how to integrate it to your Spring boot application and how to diagnose, analyse and monitor your application. You will become familiar with the use of inspectIt three main components: the agent, the server and the user interface. You will also learn how to analyse user request from the invocation sequence and detect the root causes of potential problems. You will finally see how easy it is to perform real user monitoring with inspectIt in a production like environment.

SETTING UP INSPECTIT APM
07.11.2018 13
 Download InspectIT APM from ist official
website (http://www.inspectit.rocks/)
 Run the Central Monitoring Repository CMR with
a simple java command:
java –jar inspectit-cmr.jar
 Or run it using the startup.sh script to ensure
jvm compatibility

14. Senacor Technologies AG
 Start the user interface
• Inject the java agent within your application before running it

Here it’s about monitoring the client side of a web appplication,
things like:
 Rendering time in the browser
 Loaded resources
 Javascript execution time
 …
END USER MONITORING: HOW DOES IT WORK?
07.11.2018 17

18. Senacor Technologies AG
The client side informations are complementary
to the server side informations.
Via an extension, the inspectIT agent is able to
inject the required javascript code into the
server’s response
END USER MONITORING: HOW DOES IT WORK?
07.11.2018 18

19. Senacor Technologies AG
The metrics provided by the
performance.timing.api and the resource.api
(available via property values in the browser)
should be included in the instrumentation
Javascript functions and Ajax calls should also be
included
END USER MONITORING: HOW DOES IT WORK?
07.11.2018 19

20. Senacor Technologies AG
The gathered monitoring informations are then
transmitted to the InspectIT agent and combined
with server side traces.

NOTIFICATIONS AND THRESHOLDS
07.11.2018 25
In order to be able to send notifications when
thresholds are violated, the following features
of the CMR should be First enabled (or activated):
 Long term data persistence
 Alerting

26. Senacor Technologies AG
It is possible to set up a web based UI to use with
InspectIT APM. For example we could use Grafana
in combination with the long term persistence
Database to set up a web based UI.
