Introduction

AppDynamics provides a rich source of information about your monitored applications, including the performance of individual business activities, dependency flow between application components, and details on every business transaction in an instrumented environment. We provide a rich toolkit for turning the vast corpus of data captured by AppDynamics into valuable insights.

AppDynamics DEXTER (Data Extraction and Enhanced Reporting) can make this process even faster and simpler. DEXTER provides new ways to unlock the data stored in the AppDynamics platform. You can analyze this information in a number of data warehousing and visualization applications, and combine it with your own data to generate customized reports.

Walkthrough

This 3 part walkthrough provides introduction into features and capabilities of AppDynamics DEXTER.

Report	Image	Purpose
Entities, Metrics and Snapshots Visualizations		In Walkthrough Part 1, we discover how Metrics, Events and Snapshots extracted from the AppDynamics Platform become available for offline data mining and archival use
Data Mining Snapshots		In Walkthrough Part 2, we dig deep into application performance analysis with Snapshot data using data mining and visual data analysis tools.
Advanced Snapshot and Exit Call Exploration		In Walkthrough Part 3, we look at the more advanced reports that allow you to focus on your application performance and application configuration utilizing Flame Graphs, Sankey flow diagrams and visual data analysis tools

Get Started

Install Application

Download latest release from Releases section, (AppDynamics.DEXTER.#.#.#.#.zip)

Unzip to some location, for example, C:\AppDynamics\DEXTER or /home/yourusername/DEXTER.

Credentials

You will need AppDynamics Internal account to use with DEXTER.

Only AppDynamics authentication is supported. LDAP or SAML credentials can not be used.

The account must have at least READ-level access to the APM Applications and other components that you need.

For Configuration, Controller Settings and User RBAC inventory reports, you will need Account Owner higher-level permissions to retrieve that data.

If the user you choose does not have required rights, AppDynamics DEXTER will simply not render those reports but should continue to run.

Job File

Specify data to operate on with Job File. Review some of the Job File Examples.

The template job file is called DefaultJob.json. Make a copy of it and modify according to your needs using your favorite text editor.

Alternatively, create the Job File using DEXTER-UI visual tool.

Run Application

DEXTER can run on Windows, Mac or Linux.

It uses .NET Framework and can run using either .NET Full Framework 4.7.2 or .NET Core Framework 3.1.

Run on Windows

When running on Windows, you can choose to run version built using either .NET Full or .NET Core frameworks.

For .NET Full framework version (full-win) or .NET Core portable version (core-win-portable), make sure those frameworks are installed on your OS.

For .NET Core self-contained version (core-win), no additional installations are necessary because .NET Core runtime is included with application.

Framework	Folder	Command
.NET Full 4.7.2 Install	full-win	`full-win\AppDynamics.Dexter.exe --job-file MyJob.json`
.NET Core 3.1 Install, Prerequisites	core	`dotnet core-win-portable\AppDynamics.Dexter.dll --job-file MyJob.json`
.NET Core 3.1 self-contained	core-win	`core-win\AppDynamics.Dexter.exe --job-file MyJob.json`

Run on Mac OS

When running on Mac, you can choose between version using already installed .NET Core framework or the self-contained option.

For .NET Core portable version (core-osx-portable), make sure .NET Core Framework is installed on your OS.

For .NET Core self-contained version (core-osx), no additional installations are necessary because .NET Core runtime is included with application.

Framework	Folder	Command
.NET Core 3.1 Install, Prerequisites	core	`dotnet core-osx-portable/AppDynamics.Dexter.dll --job-file MyJob.json`
.NET Core 3.1 self-contained	core-osx	`core-osx/AppDynamics.Dexter --job-file MyJob.json`

Remove quarantine attribute

NOTE: If you are running on Mac Catalina, the Gatekeeper application will complain that DEXTER DLLs come from untrusted source while executing the application.

To counteract it, remove "com.apple.quarantine" attribute from the downloaded ZIP file before extracting it by running the following command:

xattr -d com.apple.quarantine AppDynamics.DEXTER.*.zip

Set Execute Permissions on Mac

After extracting the binaries, you must mark AppDynamics.Dexter as executable by running the following command:

chmod 755 AppDynamics.Dexter

Run on Linux

When running on Linux, you can choose between version using already installed .NET Core framework or the self-contained option.

For .NET Core portable version (core-linux-portable), make sure .NET Core Framework is installed on your OS.

For .NET Core self-contained version (core-linux), no additional installations are necessary because .NET Core runtime is included with application.

Framework	Folder	Command
.NET Core 3.1 Install, Prerequisites	core	`dotnet core-linux-portable/AppDynamics.Dexter.dll --job-file MyJob.json`
.NET Core 3.1 self-contained	core-linux	`core-linux/AppDynamics.Dexter --job-file MyJob.json`

Set Execute Permissions on Linux

After extracting the binaries, you must mark AppDynamics.Dexter as executable:

chmod 755 AppDynamics.Dexter

Proxy

If you are behind corporate proxy, configure Proxy Settings.

Advanced Configuration

Understand which metrics are extracted by default and add your own Metric Sets to extract more.

Review all available Command Line Parameters.

Understand execution sequence in Phases and Job Steps.

Stop and restart the job at any time and at any step using Restart Job From Specific Step.

Understand Durations of Job Steps.

Review Controller Impact.

Output Folder Structure

AppDynamics DEXTER outputs data into Output folder specified in -o/--outputfolder command-line parameter. By default, output folder is:

"C:\AppD.Dexter.Out" is assumed on Windows
"%HOME%\AppD.Dexter.Out" is assumed on Mac and Linux

For example, if you specified myextract.json, the Output folder is C:\AppD.Dexter.Out\myextract on Windows or /user/home/AppD.Dexter.Out/myextract on Mac/Linux.

Data from Controller that is extracted during Extract phase is saved to [Output Folder]\Data folder.

Converted data that is produced during Index phase is saved to [Output Folder]\Index folder.

Final CSV files and Excel reports that are produced during Report are saved to [Output Folder]\Report folder

Report Folder Contents Full Size

There is a lot of file I/O happening in the Output folder. Remove the Output folder from any Antivirus monitoring, otherwise Extraction and Indexing is going to take a lot longer.

Excel Reports

AppDynamics DEXTER builds Excel documents from the CSV files.

Opening Excel Reports

All Microsoft Office products (2013/2016/2019/365/Office Online) can handle these Excel reports. Occasionally, older versions (2013, 2016) may complain about workbooks being corrupt, but it is mostly due to harmless conditional formatting forumulas.

Google Sheets can handle these Excel Reports although some displays in Pivots is a bit off.

Libre Office struggles with rendering of some tables but it gets full grades for trying. You can easily load CSV files instead.

Power BI Reports

AppDynamics DEXTER includes templates for Microsoft PowerBI, which is a great visual analytics tool that is free for local desktop use on Windows workstations.

Using Power BI Templates to Create Reports

PowerBI report templates are provided with AppDynamics DEXTER in PowerBITemplates folder.

Available PowerBI Templates Full Size

To create a PowerBI report with the data, open PowerBI report template (*.pbit file) and provide path to the [Output]\Report folder when prompted.

Specify Path to Report Data Full Size

You can then save the results as *.pbix report file. These can be uploaded into PowerBI Server or PowerBI Online for displaying in the browser.

Adjust Power BI Reports to Your Locale

PowerBI templates are built with en-US locale and templates do not automatically adjust to your machine’s locale. This can cause errors during load of data as the date parsing gets confused.

Perform these steps to correct these load errors:

Accept the errors encountered during the load process
Click File\Options menu
Navigate to Settings\Options\Current File\Regional Settings
Set the Locale drop-down to locale of the system on which the report was produced
Re-run all the queries using Refresh all data sources command
