Suspicious events alerts - Streaming module

This repository contains a Flink application and an Elasticsearch-Kibana stack to monitor events on a dashboard.

Dashboard

See demo/demo-dashbord.mp4 to see how it works !

Get your environment running

Install Docker

Please follow instructions here : https://docs.docker.com/v17.09/engine/installation/

Install Maven

Instruction here : https://maven.apache.org/install.html

Startup application

Install ElasticSearch and Kibana with docker - docker / kibana
Launch your ElasticSearch and Kibana containers following the instructions in the previous links (If you specify another port for any reasons, make sure that the ports are the same as the one provided in the flink files)
Start Kafka cluster (which contains 2 topics "clicks" and "displays")

$> cd docker/kafka-zk
$> docker-compose up -d

Build the project using Maven and launch the ActivityConsumer main method (for Java). Suspicious entities will be outputed to quickstart/alerts.txt file.
Go to localhost:5601 to access Kibana. An index named activitystats has been created where you can check on Menu > Stack Management > Index Management. Reload indices if necessary.
To import the dashboard, go to Menu > Stack Management > Saved Object > Import and select the kibana/dashboard.ndjson file
Click on the dashboard name once loaded or go to Menu > Dashboard > [Dashboard name]. You should wait around 10 minutes before a few events are injected to Elasticsearch.

Read kafka topics using CLI

Now you have a Kafka cluster running, let's try to read from some topics. clicks and displays topics should have been automatically created from previous step. We want to read those topics from our machine (not from a docker container). Depending on your OS, Kafka is either running on a VM (using docker-machine) or directly in your host. In the following steps, I'm assuming docker is running directly on your host.

Download Kafka scripts

Download https://archive.apache.org/dist/kafka/2.0.1/kafka_2.11-2.0.1.tgz Then extract the file :

$> tar xf kafka_2.11-2.0.1.tgz
$> cd kafka_2.11-2.0.1/bin
$> kafkacat -b localhost:9092 -t clicks

You will notice in the python script we're targeting port 9293 since it's running from a container Cf. kafka cluster config

Inject events to Kafka

As seen in previous step, Kafka clicks topic is empty, let's generate some events and read them : In another shell :

$> cd flink-exercices/docker/generate_kafka_events
$> docker build -t python-kafka-generate .

This will build a simple image with python-kafka dependency.

$> docker run -it --network kafka-zk_bridge --rm  -v "$PWD":/usr/src/myapp -w /usr/src/myapp python-kafka-generate python generator.py

Now, if you switch back to kafkacat shell, you should see many events!

Task description

The goal of the project is to create a Flink application which will read from Kafka clicks and displays, detect some suspicious/fraudulent activities and output the suspicious events into a file.
