😻 Fattest Cat @ San Francisco SPCA 😻

Scripting Integration + JS

Some cats are born fat, some achieve fatness, others have fatness thrust upon them. You can find all of them at the San Francisco SPCA.

Overview

In this exercise you'll learn how to ingest the name and weight (lbs) of each cat up for adoption at the San Francisco SPCA into Dynatrace. We will use dynatrace_ingest to ingest these metrics to see which one weighs the most by continuously monitoring them in Dynatrace.

Prerequisites

Node.js
Linux
npm
git
OneAgent installed on host
Scripting integration enabled

Step 1: Getting Started

Pull down the code repo.

git clone https://github.com/geoteo/dt-fat-cat-hack-js

Change directories.
```
cd dt-fat-cat-hack-js
```
Install the necessary packages.
```
npm i
```
Review the code in src/fetch_cats.js and src/print_fattest_cat.js using your favorite editor.
Review the following Dynatrace documentation Metric ingestion protocol.

Step 2. Execute the script to perform a single iteration.

Provided data points must follow the metrics ingestion protocol. The general syntax of metric ingestion is the following:
```
metric.key,dimensions payload
```
Run the script.
```
node src/print_fattest_cat.js
```
Review output to terminal.

Step 3. Automate the process to execute the script every 10 seconds!

Run the following bash command in your terminal:

 while true; do node src/print_fattest_cat.js; sleep 10; done

Step 4. Query Data in Data Explorer

Dynatrace UI -> Explore Data -> animal.cat.weight -> Max -> Split by name
