Q: What is Dynatrace?
Ans:

Dynatrace is a software-intelligence monitoring platform that allows you to monitor your complete infrastructure, including hosts, processes, and networks. Users can do log monitoring and view information such as total network traffic, CPU use of your hosts, process response time, and more.

Q: What is APM in Dynatrace?
Ans:

The process of tracking critical software application performance metrics using monitoring tools and telemetry data is known as Application Performance Monitoring (APM). APM is used by practitioners to assure system availability, optimise service performance and response times, and enhance user experiences.

Q: What is OpenTelemetry in Dynatrace?
Ans:

OpenTelemetry consists of a set of tools, APIs, and SDKs. It can be used to instrument, generate, collect, and export telemetry data (metrics, logs, and traces) for analysis in order to get insights into the performance and behaviour of your software.

Dynatrace supports OpenTelemetry trace ingest for open, automatic, and intelligent monitoring. OpenTelemetry metrics exporters are available from Dynatrace for the Java JavaScript/Node.js, .NET, Go,Python, languages.

Q: How does Dynatrace work?
Ans:

Dynatrace server, which comprises a host and an agent, should be installed on your system. It features a dashboard where we can diagnose our system all in one spot.

If we wish, our server can simply interact with other agents. To do so, we need to run some commands through the terminal, and then we can easily see the user interaction and also change the time.

Q: How does Dynatrace OneAgent work?
Ans:

OneAgent is a collection of customised processes that execute on each monitored host. OneAgent gathers metrics from the operating system on which it operates and compares them to performance metrics. Dynatrace is then notified of the most essential metrics.

OneAgent may also perform in-depth monitoring of specific technologies (Java, Node.js,.NET, and others) by injecting itself into those processes and monitoring their performance from the inside.

OneAgent injects a JavaScript tag into the HTML of each application page served by your web servers to provide Real User Monitoring. With these JavaScript tags in place, as well as a related module that is immediately loaded on your web server and requires no configuration.

Q: What are the Benefits of Dynatrace?
Ans:

1. Detection and Diagnosis : Dynatrace, a comprehensive monitoring system, assists businesses in detecting and diagnosing performance and availability issues.
2. Automation that is really effective. Over 100,000 hosts may be monitored automatically using Dynatrace.
3. Big Data : Dynatrace specialises in large data analytics.
4. Self-healing at scale
5. Dynatrace Integrations : Amazon EC2,HipChat, ManageEngine AlarmsOne, OpsGenie, PagerDuty, ServiceNow, Slack, VictorOps

Q: What is the difference between Dynatrace and Appdynamics APM tools?
Ans:

Dynatrace's agents are meant to capture limited stack traces for every transaction execution, whereas AppDynamics has chosen the anomaly diagnostic technique, which means that more complete stack traces are only captured when a performance baseline or threshold is breached.

Q: Can we use simply Dynatrace for performance testing instead of Apache JMeter? (or other Testing tools)?
Ans:

Dynatrace is an APM tool that does not generate load but may be used to collect metrics from the system under test such as CPU, RAM, Network, Disk, Swap use, HTTP calls, database calls, application-specific metrics, and so on.

JMeter is a tool that generates load by simulating the behaviour of a real user, and that does not collect any metrics from the system under test (until using a special plugin such as JMeter PerfMon Plugin)

Q: How to disable Dynatrace to collect debug builds for Android?
Ans:

In Dynatrace, we must create two different apps and utilise this configuration. Development data (debug) is then removed from the production data.

dynatrace {
    configurations {
        debug {
            variantFilter "[dD]ebug"
            autoStart {
                applicationId '<DebugApplicationID>'
                beaconUrl '<ProvidedBeaconURL>'
            }
        }
        prod {
            variantFilter "[rR]elease"
            autoStart {
                applicationId '<ProductionApplicationID>'
                beaconUrl '<ProvidedBeaconURL>'
            }
        }
    }
}

Q: Can we use DynaTrace to monitor column value of a database table?
Ans:

You can create a OneAgent extension that retrieves data from a database table and sends it back to Dynatrace. Only then you can do some alerting.
Follow this Dynatrace guide to create your own oneagent extension.
