What are three valid reasons to use the AppDynamics REST API to retrieve metrics? (Choose three.)

Ato archive 1-minute granularity data

Bto create a custom report to be run monthly to show average node availability

Cto calculate a new metric based on two existing metrics

Dto evaluate health rules

Eto retrieve health rule violations

Fto create an alert using a baseline to send to an internal ticketing system

Show Suggested Answer

Suggested Answer: A, C, E

The AppDynamics REST API to retrieve metrics allows you to get values generated for metrics by specifying the path of the metric and the time frame for the data1.Some of the valid reasons to use this API are12:

To archive 1-minute granularity data. The AppDynamics Controller stores metric data at different levels of granularity depending on the retention period. For example, it stores 1-minute granularity data for 8 days, 10-minute granularity data for 32 days, and 1-hour granularity data for 365 days. If you want to archive the 1-minute granularity data for longer than 8 days, you can use the API to retrieve and store the data in an external database or file system.

To calculate a new metric based on two existing metrics. The AppDynamics Controller provides some built-in metrics such as average response time, calls per minute, errors per minute, etc. However, you may want to calculate a new metric that is not available in the Controller, such as the ratio of errors to calls, or the percentage of slow transactions. You can use the API to retrieve the values of the existing metrics and perform the calculation using your own logic or formula.

To retrieve health rule violations. Health rules are the rules that define the performance and availability thresholds for your application components. When a health rule is violated, the AppDynamics Controller generates an event and optionally triggers a policy action. You can use the API to retrieve the list of health rule violations for a given application, time range, and severity level. This can help you monitor and troubleshoot the health of your application and take corrective actions if needed.Reference:Retrieve Metric Data,Health Rule API

I agree. It's all about using the data from the API to improve monitoring and troubleshooting processes.

Definitely. And being able to calculate new metrics based on existing ones can provide deeper insights into application performance.

That makes sense. It's important to be able to track and report on performance metrics regularly.

Those are both good points. I would add that creating custom reports to show average node availability is another valid reason to use the API.

I agree with that, but I also think another reason could be to evaluate health rules.

I think one reason to use the AppDynamics REST API is to retrieve health rule violations.

I believe another valid reason would be to create alerts based on baselines for the ticketing system.

Definitely, and we can also retrieve health rule violations using the API.

Yes, that's a great idea. We can also use it to evaluate health rules, right?

Totally. And let's not forget the humor factor - I'm picturing someone trying to use the API to evaluate health rules and just getting a massive migraine instead. 'Excuse me, AppDynamics, I think your API is making me sick!'

I'm with you all on that. The ability to calculate new metrics could be really powerful too. AppDynamics has a ton of data, so being able to combine and analyze it however you need is a big advantage of the API.

I agree, C, E, and B are the three best options here. Being able to pull the data and create your own reports is super useful, and understanding health rule violations is crucial for monitoring application performance.

Hmm, this is an interesting question. I think the key reasons to use the AppDynamics REST API would be to create custom reports, calculate new metrics, and retrieve health rule violations. A and F seem a bit more specific, while the others are more broadly applicable.
