An exception in AppDynamics is a code-level event that indicates a problem or abnormality in the

execution of a business transaction. AppDynamics captures and presents information on exceptions

in the monitored environment, and allows you to configure the rules and criteria for detecting and

reporting exceptions.

According to the Errors and Exceptions - AppDynamics, the following two types of events would be

marked as an exception in AppDynamics:

A custom-configured error method and error message: This is a type of event that you can define as

an exception based on a specific method and message that indicate an error condition in your

application code. You can configure the error detection rules to mark a business transaction as an

error and capture the exception information when such a method and message are encountered. For

example, you can configure a rule to mark a business transaction as an error and capture the

exception when the method com.example.MyClass.myMethod returns the message Invalid input.

Any message that is logged with a severity of Error or Fatal: This is a type of event that AppDynamics

automatically detects as an exception based on the log messages that are generated by your

application code. AppDynamics scans the log messages for the keywords Error or Fatal, and marks

the business transaction as an error and captures the exception information when such a message is

found. For example, AppDynamics will mark a business transaction as an error and capture the

exception when the log message contains Error: Null pointer exception.

Therefore, B (a custom-configured error method and error message) and C (any message that is

logged with a severity of Error or Fatal) are two types of events that would be marked as an

exception in AppDynamics. Reference:

To capture business data for Transaction Analytics, you must first configure a data collector. A data

collector is a configuration that specifies what data to capture from a business transaction and how

to store it in the analytics platform. You can capture data from HTTP requests, method invocations,

custom fields, or information points. You can also apply filters and transformations to the captured

data. Once you have configured a data collector, you can use it to enrich the transaction analytics

data with business context and enable advanced queries and visualizations

According to the Java Memory Leaks document1, one of the ways to detect and troubleshoot Java

memory leaks is to use the Automatic Leak Detection feature on the Memory tab of the Node

Dashboard. This feature captures and analyzes the collections that are actively used and growing in

size over time, indicating a potential memory leak. You can also drill down into the leaking

collections to see the content summary and the access traces that show the code path and the

business transactions that access the collection. Therefore, the correct answer is D. Examining the

values on the Server tab, configuring Object Instance Tracking, or verifying and adjusting the Memory

Monitoring configuration may not directly reveal the source of the memory leak, but they may

provide some useful information or metrics to support the diagnosis. Reference:

Java Memory Leaks

Percentile metrics are a way to measure the distribution of response times for a Business

Transaction. They show the value below which a certain percentage of measurements fall. For

example, the 50th percentile metric shows the median response time, and the 99th percentile metric

shows the worst-case response time for 99% of the transactions. To enable percentile metrics, you

need to go to Configuration > Slow Transaction Thresholds and indicate 5 whole numbers between 1

and 99 as Percentiles to Collect. You can then view the percentile metrics in the Metric Browser

under Business Transaction Performance > Business Transactions > > <Business

Transaction Name> > Percentiles.

According to the Cisco AppDynamics Associate Administrator Certification document1, one of the

topics covered in the exam is “Monitor agent performance and connectivity”. To do this, you need to

ensure that the application agent can communicate with the controller, which may require SSL

configuration if the controller is using SSL2. You also need to check that there are enough licenses

available on the controller for the application agent to register and report data3. If the agent is using

the wrong application name or does not have enough memory, it may not start at all or may crash,

which are different problems from not being able to connect to the controller. Reference:

Capacity planning is the process of estimating and allocating the resources needed to meet the

current and future demands of an application. For a regionally partitioned application, where

different users and organizations are assigned to different databases based on their location, capacity

planning requires that the administrator monitors the number of users and orgs mapped to each

database and ensures that they do not exceed the available resources.

According to the AppDynamics Analytics - AppDynamics, one way to meet this requirement is to

schedule an analytics query to check and report on the result periodically. An analytics query is a

SQL-like query that allows you to analyze and visualize the data collected by AppDynamics, such as

business transactions, logs, metrics, events, and custom data. You can use analytics queries to create

dashboards, widgets, reports, and alerts that provide insights into the performance and behavior of

your applications and their components.

To schedule an analytics query to check and report on the number of users and orgs mapped to a

database, the administrator can follow these steps:

Go to Analytics > Search.

Select the data source that contains the user and org information, such as Business Transactions,

Logs, or Custom Data.

Enter the query that counts the number of users and orgs for each database, such as SELECT

database, COUNT(DISTINCT user), COUNT(DISTINCT org) FROM data_source GROUP BY database.

Click the Save button and enter a name and description for the query.

Click the Schedule button and select the frequency, time range, and recipients for the query

execution and report delivery.

Click Save.

Therefore, A (Schedule an analytics query to check and report on the result periodically) is the

correct answer. Reference:

AppDynamics Analytics - AppDynamics

A data collector is used to capture application data in a single business transaction. A data collector is

a configuration that specifies what data to capture from a business transaction and how to store it in

the AppDynamics Controller or the analytics platform. You can capture data from HTTP requests,

method invocations, custom fields, or information points. You can also apply filters and

transformations to the captured data. The captured data can be used for various purposes, such as

adding context to business transactions, creating custom metrics, triggering health rules, enriching

transaction analytics, or creating business journeys.

To examine the Java App agent logs on a host without login access, you can use the Controller UI to

request the agent logs. This feature allows you to download the agent logs from the Controller UI

without having to access the host machine. You can specify the log level, the time range, and the file

size limit for the logs12 Reference: 1: Request Agent Logs 2: Java Agent Logging

Business Transaction metrics are the key performance indicators that measure the health and

performance of your applications. They include metrics such as average response time, calls per

minute, errors per minute, and so on. You can use various types of performance degradation analysis

to identify and troubleshoot the root causes of performance issues using Business Transaction

metrics.

According to the Troubleshoot Business Transactions - AppDynamics, the following types of

performance degradation analysis are used with Business Transaction metrics:

Correlation Analysis: This type of analysis helps you to find the correlation between different metrics

and events that may affect the performance of your Business Transactions. For example, you can use

the correlation analysis to see how the response time of a Business Transaction is related to the CPU

utilization of a node, or how the error rate of a Business Transaction is related to the number of slow

database calls.

Remote Services Analysis: This type of analysis helps you to understand how the performance of your

Business Transactions is impacted by the calls to remote services, such as databases, web services,

message queues, and so on. For example, you can use the remote services analysis to see the

response time, call count, error count, and wait time of each remote service call, and drill down to

the details of each call.

Compare Releases: This type of analysis helps you to compare the performance of your Business

Transactions across different releases of your application. For example, you can use the compare

releases analysis to see how the response time, error rate, and throughput of your Business

Transactions have changed after a new deployment, and identify any performance regressions or

improvements.

Therefore, A (Correlation Analysis), B (Remote Services Analysis), and E (Compare Releases) are

three types of performance degradation analysis that are used with Business Transaction

metrics. Reference:

According to the Upgrade the Java Agent document1, one of the reasons to upgrade AppDynamics

agents is to resolve agent issues, such as bugs, performance problems, or compatibility issues with

the Controller or the monitored application. Another reason to upgrade AppDynamics agents is to

take advantage of new features, such as enhanced metrics, dashboards, alerts, or integrations, that

are introduced in newer agent versions. Therefore, the correct answer is A and D. Database issues

and application upgrade are not directly related to the agent upgrade, unless they affect the agent

functionality or compatibility. Reference:

Upgrade the Java Agent

The default length of time events can be viewed with full detail before being purged is 7 days, unless

archived. Events are records of significant occurrences in the monitored environment, such as errors,

exceptions, policy violations, health rule violations, and more. You can view the events in the

Controller UI under Events > All Events. You can also archive the events to retain them for longer

periods or export them to external systems1 Reference: 1: Events

Snapshots are the detailed records of the execution of a business transaction, including the call stack,

the exit points, the errors, and the metrics. To locate snapshots showing slow database response, you

can use the following methods:

Go to the list of snapshots and apply a filter based on slow database response: You can access the list

of snapshots from the Business Transaction Dashboard or the Tier Dashboard. You can then apply a

filter to show only the snapshots that have a slow database response time, which is the time spent

by the business transaction in calling the database. You can specify the minimum and maximum

values for the slow database response time, or use the predefined options such as slower than 1

second, slower than 5 seconds, etc. You can also combine this filter with other filters, such as time

range, business transaction name, tier name, node name, etc. to narrow down the results1.

From the flow map, right-click the database icon and select view snapshots: You can access the flow

map from the Application Dashboard, the Business Transaction Dashboard, or the Tier Dashboard.

The flow map shows the graphical representation of the flow of the business transactions, including

the tiers, the nodes, the backends, and the remote services. You can right-click on any database icon

on the flow map and select view snapshots to see the list of snapshots that have called that

database. You can then sort or filter the snapshots by the database response time column to find the

slowest ones2.

The other options are not valid methods to locate snapshots showing slow database response. Going

to the dashboard for the database and selecting slowest database calls will show the metrics and the

flow map for the database, but not the snapshots. Going to the list of snapshots and selecting

analyze for a group of snapshots will show the summary and the comparison of the selected

snapshots, but not the database response time.

A health rule violation canceled warning event or a health rule violation canceled critical event is

generated when the health rule processor can no longer accurately assert that the health rule

violation continues to violate or that it has ended1. This can happen when the health rule is edited or

disabled, among other reasons1. Adding a new condition to the health rule or disabling the health

rule are two actions that would trigger a health rule violation canceled event, as they would change

the evaluation criteria or stop the evaluation altogether1. Marking the health rule as canceled or

removing the health rule from a policy are not valid actions, as they do not affect the health rule

configuration or status

To create a user in the web user interface, you need to go to Settings > Groups and Roles > Create

User. This option allows you to add a new user account and assign it to one or more groups. You can

also specify the user’s name, email, password, and authentication method1 Reference: 1: Create

Users

When troubleshooting an application using AppDynamics, the fastest way to narrow down a code

problem with a specific business transaction is to follow this order:

Review Application Dashboard: This is the first step to get an overview of the health and

performance of your application and its components. You can see the key metrics, such as response

time, throughput, error rate, and load, for each tier, node, and business transaction. You can also see

the health rule violations, events, and alerts that indicate any issues or anomalies in your

application.

Check transaction scorecard: This is the second step to drill down to the details of a specific business

transaction that you want to troubleshoot. You can see the transaction scorecard by clicking on the

business transaction name on the application dashboard. The transaction scorecard shows the

metrics, such as average response time, calls per minute, errors per minute, and slow calls, for the

selected business transaction. You can also see the breakdown of the response time by tier, node,

and remote service, and the distribution of the response time by percentile.

Check transaction snapshots for problems: This is the third step to identify the root cause of the code

problem for the selected business transaction. You can see the transaction snapshots by clicking on

the View Snapshots button on the transaction scorecard. Transaction snapshots are the detailed

records of the execution of a business transaction, including the call graph, the exit calls, the errors,

the exceptions, the logs, the HTTP parameters, the cookies, the session attributes, and the custom

data. You can use the transaction snapshots to analyze the code execution, the database queries, the

web service calls, the message queues, the errors, and the exceptions that affect the performance of

the business transaction.

Therefore, A (Review Application Dashboard > Check transaction scorecard > Check Transactions

snapshots for problems) is the correct answer. Reference:
