Trace Modeling and Analysis - eliminate common maintenance issues by providing the ability to visualize and troubleshoot a distributed system.

Proof of concept to demonstrate visualization of a backend system out of trace data.

Import data from a target system to Kafka and serves as the layer between Cassandra and Kafka. Based on Alpakka and reactive streams.

Build sets of suggested models from traces. Based on Kafka-streams API.

Convert SpanTrees into a BPMN 2.0 flowchart diagram in Bpmn format. Based on Kafka-streams API and Camunda.

Provide opportunity to query specific topics in Kafka via HTTP. Based on Kafka-streams API and akka-http

REQUIREMENTS:

• Docker
• docker-compose

1. docker-compose -f jaeger.yml up -d
2. Check status docker-compose -f jaeger.yml ps
   Query, Agent and Collector containers should be UP
3. Build project TraceGenApp2 ./mvnw clean package
4. Run one java -jar one/target/one.jar

7. Check localhost:16686

1. Build project ./gradlew clean installDist
2. Run kafka-cluster, Builder and Modeler docker-compose up -d
3. Run connector to import traces docker-compose -f connector_tramodana.yml up
4. Open localhost:3030
5. Find topic spans-json-original (all imported data in json format)
6. Find topic root-operation-bpmn-xml (camunda diagram)
7. Run Query module

Cassandra docker images docs. Samples contains snapshot of cassandra db, with 3 traces from Jorge's project

1. Exec: docker-compose -f jaeger.yml exec tracing-jaeger-cassandra cqlsh
2. Query DB with:

DESCRIBE KEYSPACES;
USE jaeger_v1_dc1;
DESCRIBE TABLES;
SELECT * FROM traces;

Check connector documentation and db entities
