When the Prometheus Pushgateway dependency is present on the classpath and the management. Here is a sample of the Prometheus time series for the metric spring_kafka_listener_seconds_count Prometheus requires a Service Discovery component to automatically probe the configured endpoint for metrics. I saw in another project that they have a load more: kafka_producer_request_latency_avg, kafka_producer_record_retry_total, etc. To enable Prometheus Metrics Reporter for Apache Kafka server and client components Resources. Describe the bug While I was investigating a missing kafka metric in our monitoring system I found out it was caused by our application (spring boot using micrometer) not publishing the metric kafka. xml <dependency> <groupId&gt I'm using Prometheus to collect metrics on my application which is written in Java 8 (without Spring). Application config: After configuring Kafka JMX metrics for Prometheus, the article demonstrates how to visualize the data in Grafana. 4 and I want to expose the kafka Producer metrics in the actuator/metrics endpoint of spring boot actuator pom. I am not so sure, how can I achieve this, as Prometheus is Pull based scraping method. 5. Set Up Prometheus with Spring Boot. enabled=false. Just a very brief into about Prometheus is a system for monitoring systems and services. My app does not use spring I am trying to collect metrics of Kafka consumers and producers using micrometer with Springboot. 4. 10 forks. But in prometheus I have an error: metric name http_server_requests_seconds_count does not support exemplars. Almost always I see lag_max or lag metrics as either 0 or NaN. But not able to find the class in micrometer library. 1. I use Kafka Stream to read and Kafka Producer to publish. Spring Boot (Micrometer) with Kafka Templates.

But I am seeing them all wrong. Enable Spring Actuator with Prometheus in your Spring project and configure the Prometheus server to read from it. Apache-2. In this blog post we’re going to explore how to expose Apache kafka's producer and consumer metrics to Spring Boots's actuator, and then importing them into prometheus and displaying them as a Grafana I would like to monitor Kafka metrics but unfortunately nothing related to Kafka is present under /actuator/prometheus endpoint. spring; Image generated using DALL*E 3 Viewing metrics collected in Spring Kafka. Once set up, Kafka Exporter will start providing Prometheus formatted metrics. Readme License. Code of conduct Security policy. Below I am going to demonstrate how we can use out of the box solutions using Prometheus and Grafana tools for kafka 2. Introduction. It has been determined that an issue exists for apps using spring-cloud-stream, and there is a plan to fix that. 0. Integrating Prometheus with Kafka. This will start zookeeper, kafka, schema-registry, kafka rest proxy 10k series Prometheus metrics; 500 VUh k6 testing; 50 GB logs, traces, and profiles; 50k frontend sessions; 2,232 app o11y host hours; 2,232 k8s monitoring host hours; 37,944 k8s monitoring container hours; Spring Boot Kafka Templates. 1 appVersion: 0. Forks. 2 Customize Spring boot Kafka listener metrics. Let’s start by looking at a Spring Boot application with a simple Spring Kafka producer and consumer, similar to those Run Prometheus in a docker container (and point it to the actuator/promethus endpoint so it can pull metrics periodically) Go to the Grafana web dashboard and watch the metrics stream in (for the JVM in our example) Start Kafka. *, kafka. I am able to make this work using the jmx-exporter provided by prometheus, but since that requires an agent running on a different port, I was hoping to make this work with default Micrometer and spring boot. However, when I check Prometheus, all that is there is spring_kafka_template_seconds_max and spring_kafka_template_seconds. Spring Boot Micrometer/Prometheus not logging any Metrics I added. The provided Grafana dashboards display various Kafka metrics, including CPU usage, JVM memory usage, time spent in garbage collection, message and byte counts per topic, and more. I want to work wih Kafka consumer lag metrics. x, the Kafka Streams metrics support is provided natively through Micrometer. It collects metrics from configured targets at defined intervals, evaluates rule expressions, displays the results, I am using spring boot 2. records. In order to efficiently store and query, I am thinking of storing these timeseries in Prometheus. 31, Spring Boot 2. properties file. Custom properties. 0 license Code of conduct. Prometheus requires a Service Discovery component to automatically probe the configured endpoint for metrics. x. Spring Boot Actuator and Prometheus Operator can make this process much . RELEASE. ) which should have that documentation. Modern application observability practices recommend exposing application metrics and the use of Liveness and Health Probes. Report repository Releases 4. consumer. 12. Stars. i'm trying to get metrics from spring boot application inside my prometheus operator: eks: ver. e. Relevant code: @Autowired private KafkaTe management. I have initialized a replyingKafkaTemplate as a @Bean in the @Configuration with both The class needs to be extended and its bindClient() and unbindClient() API have to be called to connect Kafka client metrics with a Micrometer collector. 44. admin. The app also acts as the consumer since this is a test application. Prometheus is an open-source systems monitoring and alerting toolkit. 6. 6. In this blog post we’re going to explore how to expose Apache kafka's producer and consumer metrics to Spring Boots's actuator, and then importing them into prometheus and displaying them as a Grafana dashboard. RELEASE) actuator endpoint. x, the metrics support is provided through a custom Micrometer metrics implementation by the binder. Moving on, let’s add an instance of the MeterRegistry class as a member to the KafkaConsumerConfig class: We’ve successfully integrated the Kafka consumer metrics and exposed them via the actuator endpoint. Micrometer acts as a bridge, enabling a I am trying to expose the Kafka producer data to actuator/Prometheus but unfortunately not working with spring boot 2. 7(auto-configured). Prometheus integrates seamlessly with Spring Boot, leveraging the Micrometer library to provide application metrics. For Spring Boot version 2. Prometheus collects and stores its metrics as time series data, i. scrape_configs: - job_name: 'spring' metrics_path: '/actuator/prometheus' static_configs: - targets: ['HOST:PORT']. I want to expose metrics on Kafka client used by the application such as counting the messages sent to each topic, number of records read, latencies, number of publishes, etc turn data from HealthIndicators into metrics (Spring Boot uses Micrometer for this) and make them available in Prometheus or Cloudwatch check consumers’ status before and after tests Kafka Enable kafka client metrics in spring app prometheus. You dont need to update/send the metrics to Prometheus. SR8 version. The RSocket Proxy approach is used so that we can monitor tasks, which are short lived, as well as long-lived stream I have a requirement to expose the Apache Kafka metrics to the spring boot (v 2. 18 kube-prometheus-stack: version: 12. 5 stars. It also shows Kafka metrics. RELEASE, and the kafka_consumer_* metrics were not showing up in /actuator/prometheus. I am also using actuator to publish metrics from /prometheus endpoint. For ephemeral or batch jobs which may not exist long enough to be scraped, Prometheus Pushgateway support can be used to expose their metrics to Prometheus. kafka metrics missing in micrometer since SpringBoot 2. It worked in spring-boot 2. metrics information is stored with the timestamp at which it was recorded, alongside optional key-value pairs called labels. 4. To make the Kafka metrics easier to see, I’ve only enable metrics Spring Boot Actuator provides dependency management and auto-configuration for Micrometer, an application metrics facade that supports numerous monitoring systems, including: To learn Below I am going to demonstrate how we can use out of the box solutions using Prometheus and Grafana tools for kafka health monitoring. metrics information is stored with the timestamp In the source code, I have enabled Prometheus, using a couple of settings in the application. Retrieving All Metrics To retrieve all metrics, make a GET request to /actuator/prometheus , as shown in the following curl-based example: The services are implemented using Spring Boot and the integration with Prometheus is through spring-boot-actuator. 7. yml:. – So, micrometer create traceId, send it to kafka topic and zipkin get it from kafka topic. 7, Reactor Kafka 1. Is anything missing in my setup? Application dependencies: Kotlin 1. etc. By the end of We will get metrics from a simple Sprint Boot application that publishes a message to Kafka as a result of a REST API call.

Setting up Prometheus to Scrape Metrics I am trying to expose apache camel kafka metrics like kafka. The RSocket Proxy approach is used so that we can monitor tasks, which are short lived, as well as long-lived By following these steps, our Spring Boot application will now expose valuable metrics that Prometheus can collect and store. Spring Kafka already exposes Kafka metrics as a JMX metrics. io are also exported (which are in that documentation). Prometheus can then be configured to scrape metrics from Kafka Exporter. jmx. The Kafka Metrics dashboard uses the prometheus data source to create a Grafana dashboard with the gauge, graph, singlestat, stat and table-old panels. This foundational setup is crucial for the next stages of our monitoring strategy, including scraping these metrics with Prometheus and visualizing them using tools like Grafana. The Spring Cloud Data Flow server uses the Prometheus RSocket Proxy, which uses the rsocket protocol for the service-discovery mechanism. You would add the following job to the scrape_configs section in your Prometheus configuration: scrape_configs: - job_name: 'kafka' static_configs: - targets Prometheus is an open-source systems monitoring and alerting toolkit. endpoint. prometheus. 6 and Kafka 2.
