How do I monitor Kafka with Prometheus?

To configure the Prometheus server to scrape the Kafka broker:

1. Log in to the Prometheus server using SSH.
2. Run the following command to see where Prometheus is reading the configuration file: ps -ef | grep prometheus. ...
3. Edit the configuration file and add a new “job” for the Prometheus server to poll.

Can Prometheus read from Kafka?

Quick Start. In this Quick Start, you configure the Kafka Connect Prometheus Metrics sink connector to read records from Kafka topics and make them accessible from an HTTP server endpoint. Prometheus then scrapes the server endpoint.

What can I monitor with Kafka?

Top 10 Kafka Metrics to Focus on First

• Network Request Rate. ...
• Network Error Rate. ...
• Under-replicated Partitions. ...
• Offline Partition Count. ...
• Total Broker Partitions. ...
• Log Flush Latency. ...
• Consumer Message Rate. ...
• Consumer Max Lag.

What is Grafana datasource?

Data sources

Data source plugins communicate with external sources of data and return the data in a format that Grafana understands. ... Use data source plugins when you want to import data from external systems.

Is there a UI for Kafka?

Kafka Tool is a GUI application for managing and using Apache Kafka clusters. It provides an intuitive UI that allows one to quickly view objects within a Kafka cluster as well as the messages stored in the topics of the cluster. ... Using Kafka Tool, you can: View metrics on cluster, broker, topic and consumer level.

What is Prometheus server?

Prometheus is an open-source systems monitoring and alerting toolkit originally built at SoundCloud. ... It is now a standalone open source project and maintained independently of any company.

What is Kafka queue?

Kafka as a Queue

A Kafka topic is sub-divided into units called partitions for fault tolerance and scalability. Consumer Groups allow Kafka to behave like a Queue, since each consumer instance in a group processes data from a non-overlapping set of partitions (within a Kafka topic).

How does Kafka exporter work?

JMX Exporter is a collector that can run as a part of an existing Java application (such as Kafka) and expose its JMX metrics over an HTTP endpoint, which can be consumed by any system such as Prometheus.

What is Prometheus JMX exporter?

Monitoring Java applications with the Prometheus JMX exporter and Grafana. ... That's the job of the Prometheus JMX Exporter. The exporter connects to Java's native metric collection system, Java Management Extensions (JMX), and converts the metrics into a format that Prometheus can understand.

What is Kafka exporter?

Kafka Exporter is an open source project to enhance monitoring of Apache Kafka brokers and clients. Kafka Exporter is provided with AMQ Streams for deployment with a Kafka cluster to extract additional metrics data from Kafka brokers related to offsets, consumer groups, consumer lag, and topics.

How do I check Kafka latency?

How to measure the latency. Since Kafka 0.10, Kafka messages contain a timestamp. This timestamp can be assigned by the producer, or is assigned by the broker if none is provided. By comparing timestamps in the output topic with timestamps in the input topic, we can measure processing latency.

What makes Kafka so fast?

Kafka uses many other techniques apart from the ones mentioned above to make systems much faster and efficient: Batching of data to reduce network calls, and also converting a lot of random writes into sequential ones. Compression of batches (and not individual messages) using LZ4, SNAPPY or GZIP codecs.

How do I monitor Kafka lag?

The simplest way to check the offsets and lag of a given consumer group is by using the CLI tools provided with Kafka. In the diagram above, you can see the details on a consumer group called my-group . The command output shows the details per partition within the topic.
