What is AppDynamics?

AppDynamics is one of the application performance monitoring tools widely used across many companies. It aims to provide visibility to the code execution in application infrastructure. An end user can monitor, analyze, configure, and troubleshoot the execution of code.

With AppDynamics, you can fully visualize stack performance and insights. It allows you to make accurate and informed decisions. As a result, this tool helps to improve business results and user experience ultimately.

Not only business and user experience, but AppDynamics precisely visualizes security, network, infrastructure, and application features. You can improve business performance and productivity to greater heights with all features.

If you want to enrich your career and become a professional in Appdynamics, then enroll in "Appdynamics Training". This course will help you to achieve excellence in this domain.

How AppDynamics work?

AppDynamics provides code-level visibility after installing agents and controllers on the applications to monitor. Each line of code is monitored by the AppDynamics agent and collects performance metrics. It forwards the metrics to the AppDynamics controller, which processes them and sends visual reports to the web browser. AppDynamics supports all major technologies in the IT industry, allowing any application to integrate AppDynamics for better full-stack development and maintenance in a distributed environment.

Now let us dive deep into each phase involved in monitoring an application using AppDynamics to know more.

Imagine a scenario where an organization's applications are deployed across multiple cloud platforms that use different service providers using versatile technologies. We deploy AppDynamics agents across the network to help discover individual business transactions. Cloud networks may combine public, private, or hybrid environments.

Within this network, the AppDynamics agents discover transactions from network topologies and share every possible detail about the transaction and its business metrics with the central AppDynamics controller. The controller uses artificial intelligence to create a baseline of the performance metrics received from the agents. These baselines will help us in backtracking the performance. If an anomaly in the network shows performance deviation from the baseline, we capture the performance to the individual line of code. This captured data helps us as a trigger to act early and gives the root cause of the performance deviance.

A detailed approach to identifying every transactional performance and the root causes will help your business avoid operational congestion in the network and reduce the time to resolve code-level issues if any.

Business owners can monitor real-time business metrics using AppDynamics which allows them to monitor, identify the problems quickly and respond with resolutions.

AppDynamics High-level Architecture

You can find the architecture of the AppDynamics workflow and its production monitoring architecture in this section. You can know what’s happening with different components and the AppDynamics actions.

AppDynamics web interface is connected to the AppDynamics controller through a web browser (Uses port 8090 in most cases) with an HTTPS connection. AppDynamics controller receives the performance metrics and the operational data of the transactions across the network from the AppDynamics agents installed over the web. The application servers in the above image indicate different languages the agents support to make AppDynamics compatible with every business, irrespective of their coding language.

AppDynamics Machine Agent Infrastructure

Infrastructure

The AppDynamics machine agent collects basic hardware metrics like operating systems, memory utilization, and disk and network details. The agent acts as the delivery channel for AppDynamics server visibility. It offers many hardware metrics and monitoring capabilities. Machine agent uses only Java to report metrics collected in AppD Controller.

The machine agent gathers multiple extensions' information and sends it to the controller. You can run remediation scripts for policy actions and JVM crash guard with the machine agent. Also, you can estimate the correlations between servers and application performance issues indicated by app agents.

AppDynamics Production Monitoring Architecture

production monitoring

The AppDynamics and DB controller interact with the cloud to monitor and diagnose transactional operations over the network. The application server and machine agent together share the data with the controller.

Know that AppDynamics Pro architecture has many components such as AppDynamics controller and UI, App agents, machine agents, web EUM, Mobile APM, and databases. AppDynamics is the central rePro architecture repository and analytics engine. App agents are usually installed in JVM,.NET, and PHP applications. Machine agents collect data about machine performance and forward them to the controller. Web EUM allows you to track how web user experience. Similarly, mobile APM helps to follow mobile application performance.

AppDynamics Key Terminology

#1.Business Application

It is the top-level container to manage the tiers and control role-based access at the controller UI.

#2.Node

A node in an AppDynamics network is an application server installed on the infrastructure physically or virtually.

#3.Tier

A tier is a virtual group of nodes based on their business operations. One AppDynamics agent cannot take charge of more than one tier.

#4.Entry Point

It is an application code that initiates business transactions.

#5.Flow Map

It represents the process flow among the nodes, tiers, and backend components over the network infrastructure.

#6.Transactional snapshot

AppDynamics allows continuous monitoring of the operations across the network and shares all the collected data metrics with the controller. These screenshots will help businesses find the root cause of the performance disturbances if any.

#7.Health Rules

Guidelines that define the respective limits for the application performances throughout the network. AppDynamics provide default health rules for businesses, which you can alter according to the business performance requirements.

#8.Health

Health defines the process performance of the application and sends colored signals to the controller. Green, yellow, and red are the color schemes that determine the performance limits per the health rules.

#9.Server Health

It defines the health status of the servers and monitors whether the performance is aligned with the health rules defined.

#10.Transaction scorecard

The label defines the status of the transaction, whether it is slow, very slow, stalled, or has some errors.
