This webinar discusses advanced business transaction configuration in AppDynamics. It covers why proper BT configuration is important, how to create custom BT rules and exclude rules, the new "BT lockdown" feature in version 4.0, and the "BT discovery tool" introduced in version 4.1. The webinar provides examples of how to use these tools to better organize BTs to more easily identify problems and set baselines and health rules.
AppDynamics Advanced BT Configuration
- 1. AppDynamics Webinars: Advanced BT Configuration Todd Radel, Senior Manager – Customer Advocacy
- 2. Agenda • Why is BT configuration important? • Creating custom BT rules and exclude rules • Using “BT lockdown” (new since 4.0) • Using “BT discovery tool” (new since 4.1) • Office hours
- 3. WHY IS BT CONFIGURATION IMPORTANT?
- 4. Why is it important to configure business transactions? • Faster and easier to find the code causing problems if your BTs are organized nicely • Metrics are computed per BT • Baselines are computed per BT • Health Rules alert on a particular BT
- 5. Default BT discovery rules • Where is “rent a movie”? • Where is “pay for a movie”? Copyright © 2015 AppDynamics. All rights reserved. 5
- 6. Simple customizations • Changing the default naming rules • Deleting or excluding BT’s one at a time • Renaming • Grouping Copyright © 2015 AppDynamics. All rights reserved. 6
- 7. Advanced customization • Creating your own custom rules • Splitting BT’s by URL, parameter, or payload • Using exclude rules Copyright © 2015 AppDynamics. All rights reserved. 7

- 9. CREATING CUSTOM BT RULES
- 10. Use cases • Excluding all pages that match a certain pattern • Naming BT’s based on parameters or payload – Part of the URL (by segment or regex) – GET or POST parameters – Cookies, session variables, header values – XML or JSON payload – Class name/method name Copyright © 2015 AppDynamics. All rights reserved. 10
- 11. Movieztream example • Search form with several different search types: – By movie title – By category – By year released • Each type follows a different code path • How do I create separate BT’s for each search type? Copyright © 2015 AppDynamics. All rights reserved. 11
- 13. What is “BT lockdown”? • New feature added in 4.0 (Java and .NET) • Prevents new BT’s from being registered • New BT’s will go into “All Other Traffic” instead • Use the “View Traffic” button to select new BT’s and promote them to the BT list • Keeps your BT list clean Copyright © 2015 AppDynamics. All rights reserved. 13
- 14. Catch-all rules • Custom rule, priority 20, matches “/movie/search.htm” • Custom rule, priority 10, matches “/movie” • Custom rule, priority 0, matches “/” Copyright © 2015 AppDynamics. All rights reserved. 14
- 15. BT lockdown vs. “catch-all” rules Copyright © 2015 AppDynamics. All rights reserved. 15 Registering new candidate BT’s Can be instantly promoted to BT list Visibility Easy to see what has been excluded Flexibility All-or-nothing approach Result Clean BT list + “All Other Traffic” Must create a higher-priority custom rule first Need to inspect snapshots to find out what has been excluded Can create “tiers” of catch-all rules with different levels of specificity Clean BT list + “Catch-All Bucket” BT lockdown Catch-all rules
- 16. USING THE BT DISCOVERY TOOL
- 17. What is the “BT discovery tool”? • New feature added in 4.1 (Java only) • Interactive console to help discover and refine BT’s • Like a “sandbox”
- 18. How it improves your workflow The Old Way 1. Create custom BT rules 2. Generate load 3. Look at discovered BT’s 4. Stop load 5. Delete discovered BT’s 6. Adjust custom BT rules 7. Repeat steps 2-7 Copyright © 2015 AppDynamics. All rights reserved. 18 The New Way 1. Start discovery session 2. Generate load 3. Look at discovered BT’s 4. Adjust custom BT rules 5. Click “Apply”

Editor's Notes
- #12: SWITCH TO DEMO Create exclude rule for admin pages /movieztream_ui/admin Create custom rules for: Search – ends with /search.htm Search by title – param title is not empty Search by category – param category is not empty
- #15: Catch-all rules were the “old way” of accomplishing the same thing.
- #16: SWITCH TO DEMO Turn on BT lockdown Change default naming to full URL Go into All other traffic http://52.23.171.140:8090/controller/#/location=APP_BT_LIST&timeRange=last_15_minutes.BEFORE_NOW.-1.-1.15&application=5
