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.

LogIsland is completely open source and free even for commercial use. Hurence provides support if required.

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

Building Logisland

to build from the source just clone source and package with maven (logisland requires a maven 3.5.2 version and beyond)

.. code-block:: sh

git clone https://github.com/Hurence/logisland.git
cd logisland
mvn clean package

the final package is available at logisland-assembly/target/logisland-1.4.0-full-bin.tar.gz

You can also download the latest release build <https://github.com/Hurence/logisland/releases>_

If you want to build with opencv support, please install OpenCV first and then

 mvn clean package -Dopencv

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: https://kafka.apache.org/downloads

Last tested version of scala version for kafka is: 2.11 with preferred release of kafka : 0.10.2.2

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 : http://d3kbcqa49mib13.cloudfront.net/

.. code-block:: sh

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

# install Spark (choose the spark version compatible with your hadoop distrib if you have one)
curl -s http://d3kbcqa49mib13.cloudfront.net/spark-<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 1.4.0
curl -s https://github.com/Hurence/logisland/releases/download/v1.0.0-RC2/logisland-1.0.0-RC2-bin.tar.gz  | tar -xz -C /usr/local/
cd /usr/local/logisland-1.4.0

# launch a logisland job
bin/logisland.sh --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

.. code-block:: sh

# launch logisland environment
cd /tmp
curl -s https://raw.githubusercontent.com/Hurence/logisland/master/logisland-framework/logisland-resources/src/main/resources/conf/docker-compose.yml > 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.

.. code-block:: sh

# install Logisland 1.4.0
curl -s https://github.com/Hurence/logisland/releases/download/v0.10.0/logisland-1.4.0-bin-hdp2.5.tar.gz  | tar -xz -C /usr/local/
cd /usr/local/logisland-1.4.0
bin/logisland.sh --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)

.. code-block:: yaml

version: 1.4.0
documentation: LogIsland job config file
engine:
  component: com.hurence.logisland.engine.spark.KafkaStreamProcessingEngine
  type: engine
  documentation: Index some apache logs with logisland
  configuration:
    spark.app.name: IndexApacheLogsDemo
    spark.master: yarn-cluster

    spark.streaming.ui.retainedBatches: 200
    spark.streaming.receiver.writeAheadLog.enable: false
    spark.ui.port: 4050
  controllerServiceConfigurations:

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

.. code-block:: yaml

    - controllerService: datastore_service
      component: com.hurence.logisland.service.elasticsearch.Elasticsearch_6_6_2_ClientService
      type: service
      documentation: elasticsearch service
      configuration:
        hosts: sandbox:9200
        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

.. code-block:: yaml

  streamConfigurations:
    - stream: parsing_stream
      component: com.hurence.logisland.stream.spark.KafkaRecordStreamParallelProcessing
      type: stream
      documentation: a processor that converts raw apache logs into structured log records
      configuration:
        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
        kafka.metadata.broker.list: 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. Please note that the datastore processor makes use of the previously defined ControllerService.

.. code-block:: yaml

      processorConfigurations:

        - processor: apache_parser
          component: com.hurence.logisland.processor.SplitText
          type: parser
          documentation: a parser that produce records from an apache log REGEX
          configuration:
            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.datastore.BulkPut
          type: processor
          documentation: a processor that indexes processed events in elasticsearch
          configuration:
            datastore.client.service: datastore_service
            default.collection: logisland
            default.type: event
            timebased.collection: yesterday
            collection.field: search_index
            type.field: record_type

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

.. code-block:: bash

bin/logisland.sh -conf conf/job-configuration.yml
