LogIsland is an event mining scalable platform designed to handle a high throughput of events.

It is highly inspired from DataFlow programming tools such as Apache Nifi, but with a highly scalable architecture.

Event mining Workflow

Here is an example of a typical event mining pipeline.

  1. Raw events (sensor data, logs, user click stream, ...) are sent to Kafka topics by a NIFI / Logstash / *Beats / Flume / Collectd (or whatever) agent
  2. Raw events are structured in Logisland Records, then processed and eventually pushed back to another Kafka topic by a Logisland streaming job
  3. Records are sent to external short living storage (Elasticsearch, Solr, Couchbase, ...) for online analytics.
  4. Records are sent to external long living storage (HBase, HDFS, ...) for offline analytics (aggregated reports or ML models).
  5. Logisland Processors handle Records to produce Alerts and Information from ML models

Online documentation

You can find the latest Logisland documentation, including a programming guide, on the project web page. This README file only contains basic setup instructions.

Browse the Java API documentation for more information.

You can follow one getting started guide through the apache log indexing tutorial.

Building Logisland

to build from the source just clone source and package with maven

git clone
cd logisland
mvn clean package -Pfull

If some tests are not passing re-run the latest command skipping the tests

mvn clean package -Pfull -skipTests

the final package is available at logisland-assembly/target/logisland-1.0.0-RC2-bin-hdp2.5.tar.gz

You can also download the latest release build

Quick start

Local Setup

Alternatively you can deploy logisland on any linux server from which Kafka and Spark are available

Replace all versions in the below code by the required versions (spark version, logisland version on specific HDP version, kafka scala version and kafka version etc.)

The Kafka distributions are available at this address: <>

Last tested version of scala version for kafka is: 2.11 with preferred release of kafka :

Last tested version of Spark is: 2.3.1 on Hadoop version: 2.7

But you should choose the Spark version that is compatible with your environment and hadoop installation if you have one (for example Spark 2.1.0 on hadoop 2.7). Note that hadoop 2.7 can run Spark 2.4.x, 2.3.x, 2.2.x, 2.1.x. Check at this URL what is available :

# install Kafka & start a zookeeper node + a broker
curl -s<kafka_release>/kafka_scala_version>-<kafka_version>.tgz | tar -xz -C /usr/local/
cd /usr/local/kafka_<scala_version>-<kafka_version>
nohup bin/ config/ > zookeeper.log 2>&1 &
JMX_PORT=10101 nohup bin/ config/ > kafka.log 2>&1 &

# install Spark (choose the spark version compatible with your hadoop distrib if you have one)
curl -s<spark-version>-bin-hadoop<hadoop-version>.tgz | tar -xz -C /usr/local/
export SPARK_HOME=/usr/local/spark-<spark-version>-bin-hadoop<hadoop-version>

# install Logisland 1.0.0-RC2
curl -s  | tar -xz -C /usr/local/
cd /usr/local/logisland-1.0.0-RC2

# launch a logisland job
bin/ --conf conf/index-apache-logs.yml

you can find some logisland job configuration samples under $LOGISLAND_HOME/conf folder

Docker setup

The easiest way to start is the launch a docker compose stack

# launch logisland environment
cd /tmp
curl -s > docker-compose.yml
docker-compose up

# sample execution of a logisland job
docker exec -i -t logisland conf/index-apache-logs.yml

Hadoop distribution setup

Launching logisland streaming apps is just easy as unarchiving logisland distribution on an edge node, editing a config with YARN parameters and submitting job.

# install Logisland 1.0.0-RC2
curl -s  | tar -xz -C /usr/local/
cd /usr/local/logisland-1.0.0-RC2
bin/ --conf conf/index-apache-logs.yml

Start a stream processing job

A Logisland stream processing job is made of a bunch of components. At least one streaming engine and 1 or more stream processors. You set them up by a YAML configuration file.

Please note that events are serialized against an Avro schema while transiting through any Kafka topic. Every spark.streaming.batchDuration (time window), each processor will handle its bunch of Records to eventually

generate some new Records to the output topic.

The following configuration.yml file contains a sample of job that parses raw Apache logs and send them to Elasticsearch.

The first part is the ProcessingEngine configuration (here a Spark streaming engine)

version: 1.0.0-RC2
documentation: LogIsland job config file
  component: com.hurence.logisland.engine.spark.KafkaStreamProcessingEngine
  type: engine
  documentation: Index some apache logs with logisland
  configuration: IndexApacheLogsDemo
    spark.master: yarn-cluster
    spark.driver.memory: 1G
    spark.driver.cores: 1
    spark.executor.memory: 2G
    spark.executor.instances: 4
    spark.executor.cores: 2
    spark.yarn.queue: default
    spark.yarn.maxAppAttempts: 4 1h
    spark.yarn.max.executor.failures: 20
    spark.yarn.executor.failuresValidityInterval: 1h
    spark.task.maxFailures: 8
    spark.serializer: org.apache.spark.serializer.KryoSerializer
    spark.streaming.batchDuration: 4000
    spark.streaming.backpressure.enabled: false
    spark.streaming.unpersist: false
    spark.streaming.blockInterval: 500
    spark.streaming.kafka.maxRatePerPartition: 3000
    spark.streaming.timeout: -1
    spark.streaming.unpersist: false
    spark.streaming.kafka.maxRetries: 3
    spark.streaming.ui.retainedBatches: 200
    spark.streaming.receiver.writeAheadLog.enable: false
    spark.ui.port: 4050

Then comes a list of ControllerService which are the shared components that interact with outside world (Elasticearch, HBase, ...)

- controllerService: elasticsearch_service
  component: com.hurence.logisland.service.elasticsearch.Elasticsearch_2_3_3_ClientService
  type: service
  documentation: elasticsearch service
    hosts: sandbox:9300 elasticsearch
    batch.size: 5000

Then comes a list of RecordStream, each of them route the input batch of Record through a pipeline of Processor to the output topic

  - stream: parsing_stream
    type: stream
    documentation: a processor that converts raw apache logs into structured log records
      kafka.input.topics: logisland_raw
      kafka.output.topics: logisland_events
      kafka.error.topics: logisland_errors
      kafka.input.topics.serializer: none
      kafka.output.topics.serializer: com.hurence.logisland.serializer.KryoSerializer
      kafka.error.topics.serializer: com.hurence.logisland.serializer.JsonSerializer sandbox:9092
      kafka.zookeeper.quorum: sandbox:2181
      kafka.topic.autoCreate: true
      kafka.topic.default.partitions: 4
      kafka.topic.default.replicationFactor: 1

Then come the configurations of all the Processor pipeline. Each Record will go through these components. Here we first parse raw apache logs and then we add those records to Elasticsearch. Pleas note that the ES processor makes use of the previously defined ControllerService.


  - processor: apache_parser
    component: com.hurence.logisland.processor.SplitText
    type: parser
    documentation: a parser that produce records from an apache log REGEX
      record.type: apache_log
      value.regex: (\S+)\s+(\S+)\s+(\S+)\s+\[([\w:\/]+\s[+\-]\d{4})\]\s+"(\S+)\s+(\S+)\s*(\S*)"\s+(\S+)\s+(\S+)
      value.fields: src_ip,identd,user,record_time,http_method,http_query,http_version,http_status,bytes_out

  - processor: es_publisher
    component: com.hurence.logisland.processor.elasticsearch.BulkAddElasticsearch
    type: processor
    documentation: a processor that indexes processed events in elasticsearch
      elasticsearch.client.service: elasticsearch_service
      default.index: logisland
      default.type: event
      timebased.index: yesterday
      es.index.field: search_index
      es.type.field: record_type

Once you've edited your configuration file, you can submit it to execution engine with the following cmd :

bin/ -conf conf/job-configuration.yml

You should jump to the tutorials section of the documentation. And then continue with components documentation
