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.
Here is an example of a typical event mining pipeline.
- Raw events (sensor data, logs, user click stream, ...) are sent to Kafka topics by a NIFI / Logstash / *Beats / Flume / Collectd (or whatever) agent
- Raw events are structured in Logisland Records, then processed and eventually pushed back to another Kafka topic by a Logisland streaming job
- Records are sent to external short living storage (Elasticsearch, Solr, Couchbase, ...) for online analytics.
- Records are sent to external long living storage (HBase, HDFS, ...) for offline analytics (aggregated reports or ML models).
- Logisland Processors handle Records to produce Alerts and Information from ML models
You can find the latest Logisland documentation, including a programming guide, on the project web page.
Or on this site web as well.
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.
to build from the source just clone source and package with maven (logisland requires a maven 3.5.2 version and beyond)
git clone https://github.com/Hurence/logisland.git
cd logisland
mvn clean packagethe final package is available at logisland-assembly/target/logisland-1.4.1-full-bin.tar.gz
You can also download the latest release build
If you want to build with opencv support, please install OpenCV first and then
mvn clean package -Dopencv
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/

# launch a logisland job
bin/logisland.sh --conf conf/index-apache-logs.ymlyou can find some logisland job configuration samples under $LOGISLAND_HOME/conf folder
The easiest way to start is the launch a docker compose stack
# 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.ymlLaunching 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 1.4.1
curl -s https://github.com/Hurence/logisland/releases/download/v0.10.0/logisland-1.4.1-bin-hdp2.5.tar.gz | tar -xz -C /usr/local/
cd /usr/local/logisland-1.4.1
bin/logisland.sh --conf conf/index-apache-logs.ymlA 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)

batch.size: 5000Then comes a list of RecordStream, each of them route the input batch of Record through a pipeline of Processor to the output topic
streamConfigurations:
