![]() ![]() You need access to your Topology object in your Java/Scala/Kotlin code. How do I retrieve my Topology description? If the application is down, the topology disappears and it becomes redish, time to call the developers! Here is an example importing a Kafka Streams application using the application.id myapplicationid and exposing a endpoint /topology:Ĭonduktor will then monitor the endpoint and display a summary (topics in and out) in the main listing: Conduktor will automatically fetch it regularly, adapt the metrics accordingly, and warn you if it's down.by URL: paste the endpoint of your application exposing its topology.Static: paste your topology directly inside Conduktor.Specify the application.id of your application.To do so, go to the Kafka Streams menu and click on IMPORT TOPOLOGY, then: They generally work with many topics (in/out/internal/intermediates) and can be reset when you want to start it fresh again.Ĭonduktor can help you monitoring these applications, and the topics being used. Kafka Streams applications are outside of the scope of Kafka itself, they can be running anywhere. How to import a Topology inside Conduktor, and why? This way, you can monitor your application state, topics, statestores etc. It will start a typical Kafka Streams application and expose an HTTP API to be connected to Conduktor (optional). It will start a typical Kafka Streams application and expose an HTTP API to be connected to Conduktor (optional). We're providing an example you can try and fork: Of the cluster and the proper authorizations.Kafka Streams Where to start with Kafka Streams? A Kafka cluster is a collection of brokers who organize events into topics and store them durably for a configurable amount of time. ensure you have access to the *advertised listeners* Apache Kafka is a distributed event streaming platform, which can ingest events from different source systems at scale and store them in a fault-tolerant distributed system called a Kafka cluster. Kafka: localhost:9092 <- ERROR: "The broker is reachableīut Kafka can't connect. I'm trying to use: zookeeper: localhost:2181 <- working 19:45:09,082 INFO success: kafka entered RUNNING state, process has stayed up for > than 1 seconds (startsecs) 19:45:09,081 INFO success: zookeeper entered RUNNING state, process has stayed up for > than 1 seconds (startsecs) 19:45:08,031 INFO spawned: 'zookeeper' with pid 8 Most types are simple and exist in JSON and Apache Avro (like integers, strings) but some needs a special handling by Conduktor to be 'understood' and properly converted. When sending the data, Conduktor translates the JSON payload to an Apache Avro format. You can use the test driver to verify that your specified processor topology computes the correct result with the manually piped in data records - Source. When producing data from Conduktor Desktop, the format must be in JSON. The test-utils package provides a TopologyTestDriver that can be used pipe data through a Topology. 19:45:07,027 INFO supervisord started with pid 1 To support testing of Streams applications, Kafka provides a test-utils artifact. 19:45:07,027 CRIT Server 'unix_http_server' running without any HTTP authentication checking 19:45:07,027 INFO RPC interface 'supervisor' initialized 19:45:07,019 WARN Included extra file "/etc/supervisor/conf.d/nf" during parsing ![]() 19:45:07,018 CRIT Supervisor running as root (no user in config file) 'Supervisord is running as root and it is searching ' usr/lib/python2.7/dist-packages/supervisor/options.py:296: UserWarning: Supervisord is running as root and it is searching for its configuration file in default locations (including its current working directory) you probably want to specify a "-c" argument specifying an absolute path to a configuration file for improved security. Status: Downloaded newer image for spotify/kafka:latest I tried to use which is a container that contains zookeeper and kafka, but I don't know what is the ip of the kafka: docker run -p 2181:2181 -p 9092:9092 -env ADVERTISED_HOST=`docker-machine ip \`docker-machine active\`` -env ADVERTISED_PORT=9092 spotify/kafka I'm new to kafka and I can't find a way to connect to a kafka that I setup in docker container: I have a requirement for a small kafka setup for testing. ![]()
