Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. Need to check for tool to monitor Kafka in production. Also tool does not need to have license or heavy hardware. In particular I need a tool to evaluate consumer offset on topic,health of topic.
It enables faster monitoring of Kafka data pipelines. Note that this is recommended for development environments. Confluent Another option is Confluent Enterprise which is a Kafka distribution for production environments.
It also includes Control Centrewhich is a management system for Apache-Kafka that enables cluster monitoring and management from a User Interface. Yahoo Kafka Manager Kafka's Manager is a tool for monitoring Kafka offering less functionality compared to the aforementioned tools.
The tool displays information such as brokers, topics, partitions, and even lets you view messages. It is a light weight application that runs on Spring Boot and requires very little configuration. LinkedIn Burrow Burrow is a monitoring companion for Apache Kafka that provides consumer lag checking as a service without the need for specifying thresholds.
It monitors committed offsets for all consumers and calculates the status of those consumers on demand. An HTTP endpoint is provided to request status on demand, as well as provide other Kafka cluster information. There are also configurable notifiers that can send status out via email or HTTP calls to another service.
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. It contains features geared towards both developers and administrators.Comment 0.
Kafka itself comes with command line tools that can perform all necessary administrative tasks.
Moreover, it is getting difficult to work with them when your clusters grow large, or when you have several clusters. The first is Kafka Tool. It is a Windows program that can connect to a Kafka cluster and do all basic tasks.
It can list brokers, topics, or consumers and their properties. It allows you to create new topics or update existing ones, and you can even look at the messages in a topic or partition. Although it is very useful, its UI seems somewhat old, and it lacks some monitoring features, such as topic lag.
Also, it is not free for commercial use. So, you can't really use it at work unless you pay for it. Technically you can, but this would violate the licensing terms and put you and your employer at risk. Kafka Manager is a web-based management system for Kafka developed at Yahoo. It is capable of administrating multiple clusters ; it can show statistics on individual brokers or topics, such as messages per second, lag, and etc.
But, it's more of an administrative tool. Unfortunately, you can't use it to browse messages. It also requires access to ZooKeeper nodes, so you might not be able to use it in some production environments, where ZooKeeper nodes are typically firewalled. Edit application. Now you should build Kafka Manager. It uses the play framework, but it is installed and configured automatically unlike Kafka web console that is discussed later. In the directory where you unzipped it, run:.
This can take a long time to complete about 30 minutes on the first build, as it has to download a bunch of dependencies.
This will create a distribution file. This is the default, but you can change it by adding -Dhttp.Moreover, it is getting difficult to work with them when your clusters grow large or when you have several clusters.
First is Kafka tool. It is a windows program that can connect to a Kafka cluster and do all basic tasks.Lxc presets
It can list brokers, topics or consumers and their properties. It allows you to create new topics or update existing ones and you can even look at the messages in a topic or partition. It is capable of administrating multiple clusters, it can show statistics on individual brokers or topics such as messages per second, lag ans so on.
I think this is the best tool out there at the moment. Here are the steps to install it: First, download the zip distribution from the link above and unzip it. Edit application. Now you should build kafka manager. It uses play framework but it is installed and configured automatically unlike Kafka web console that is discussed later. In the directory where you unzipped it, run:.
Reintroducing Kafdrop 3
Before we run it, there seems to have a bug that prevents kafka-manager to automatically pick up the configuration file when starting as reported here.
The workaround is to explicitly provide the configuration file at startup:. View full size image. The UI seems very nice but the project page says it is no longer maintained and supported and advise to consider using Kafka manager instead.
Kafdrop is another web based Kafka manager. You can download it from here. This may take some time to complete. The default listening port isbut you can change it by adding —server.
We will not cover it in detail this time because it does not fall into the same category as the previous tools mentioned here. It does not have a graphical user interface and it does not have any cluster management capabilities. It can also automatically notify an administrator by email or http about any problems. I covered it in more detail in this post: Monitoring Kafka consumer lag with Burrow. Excellent post. Found the list of tools particularly helpful.
Whilst Kafka is an excellent streaming platform, the tooling around it has been subpar. The CLI tools that come with it is are just doing their needful and are awkward to use when you have to debug a problem in production. I am not getting consumer group.
Can you please let me knaw what to do. I get when it when I use console consumer but not through consumer program. This site uses Akismet to reduce spam. Learn how your comment data is processed.

Single Node Setup for first-time users. Cluster Setup for large, distributed clusters. Hadoop MapReduce is a software framework for easily writing applications which process vast amounts of data multi-terabyte data-sets in-parallel on large clusters thousands of nodes of commodity hardware in a reliable, fault-tolerant manner.
A MapReduce job usually splits the input data-set into independent chunks which are processed by the map tasks in a completely parallel manner. The framework sorts the outputs of the maps, which are then input to the reduce tasks. Typically both the input and the output of the job are stored in a file-system. The framework takes care of scheduling tasks, monitoring them and re-executes the failed tasks.
This configuration allows the framework to effectively schedule tasks on the nodes where data is already present, resulting in very high aggregate bandwidth across the cluster.
These, and other job parameters, comprise the job configuration. Hadoop Streaming is a utility which allows users to create and run jobs with any executables e. The key and value classes have to be serializable by the framework and hence need to implement the Writable interface.

Additionally, the key classes have to implement the WritableComparable interface to facilitate sorting by the framework. Before we jump into the details, lets walk through an example MapReduce application to get a flavour for how they work. WordCount is a simple application that counts the number of occurrences of each word in a given input set. This works with a local-standalone, pseudo-distributed or fully-distributed Hadoop installation Single Node Setup.
Applications can specify a comma separated list of paths which would be present in the current working directory of the task using the option -files.
The -libjars option allows applications to add jars to the classpaths of the maps and reduces. The option -archives allows them to pass comma separated list of archives as arguments. These archives are unarchived and a link with name of the archive is created in the current working directory of tasks. More details about the command line options are available at Commands Guide.
Running wordcount example with -libjars-files and -archives :. Here, myarchive. Users can specify a different symbolic name for files and archives passed through -files and -archives option, using.
The archive mytar. Applications can specify environment variables for mapper, reducer, and application master tasks by specifying them on the command line using the options -Dmapreduce. The Mapper implementation, via the map method, processes one line at a time, as provided by the specified TextInputFormat. WordCount also specifies a combiner. Hence, the output of each map is passed through the local combiner which is same as the Reducer as per the job configuration for local aggregation, after being sorted on the key s.
The Reducer implementation, via the reduce method just sums up the values, which are the occurrence counts for each key i. It then calls the job. This section provides a reasonable amount of detail on every user-facing aspect of the MapReduce framework.

This should help users implement, configure and tune their jobs in a fine-grained manner. Let us first take the Mapper and Reducer interfaces.How To Fix .jar Files Not Opening Even With Java Installed (Optifine, Minecraft, Forge)
Applications typically implement them to provide the map and reduce methods. Finally, we will wrap up by discussing some useful features of the framework such as the DistributedCacheIsolationRunner etc.
Applications typically implement the Mapper and Reducer interfaces to provide the map and reduce methods. These form the core of the job. Maps are the individual tasks that transform input records into intermediate records.Lenses is compatible with your Cloud setup and Kafka Managed Services.

But what I need is to see the dependency tree for a 3rd party artifact. I guess I can create an empty project, but I'm looking for something easier I need to do this for several artifacts. Unfortunately dependency mojo must use pom. Cannot execute mojo: tree. It requires a project with an existing pom.
For example see org. Part of dependency artifact is a pom. That specifies it's dependency. And you can execute mvn dependency:tree on this pom. If you bother creating a sample project and adding your 3rd party dependency to that, then you can run the following in order to see the full hierarchy of the dependencies.
An empty pattern segment is treated as an implicit wildcard. Edit: Please note that despite the advantages of using verbose parameter, it might not be so accurate in some conditions. Because it uses Maven 2 algorithm and may give wrong results when used with Maven 3. See also How to list the transitive dependencies of an artifact from a repository?Tcga expression data
If you use a current version of m2eclipse which you should if you use eclipse and maven :. The pom will open in the pom editor, from which you can select the tab Dependency Hierarchy to view the dependency hierarchy as the name suggests If your artifact is not a dependency of a given project, your best bet is to use a repository search engine.
Many of them describes the dependencies of a given artifact. I know this post is quite old, but still, if anyone using IntelliJ any want to see dependency tree directly in IDE then they can install Maven Helper Plugin plugin.
