Hawkular Data Mining

About

Data Mining is time series prediction engine for Hawkular. It autonomously selects best model for time series being modelled. Produced prediction can be used for alert prediction or in predictive charts in UI.

Module is split into several artifacts:

hawkular-datamining-forecast - lightweight time series forecasting library
hawkular-datamining-rest - standalone web application with REST API
hawkular-datamining-dist - web application dedicated for deployment into Hawkular

Build & Run

To run standalone instance of Data Mining:

$ mvn install -Pdev
# run Wildfly with deployed Data Mining
$ hawkular-datamining-rest/target/wildfly-*/bin/standalone.sh

To run Hawkular with Data Mining, clone and build Hawkular branch datamining and run the server. Predictive charts are located in Explorer tab.

# build Hawkular with deployed Data Mining
$ git clone -b datamining git@github.com:hawkular/hawkular.git
$ cd hawkular
$ mvn install -Pdev
# run Hawkular
$ dist/target/hawkular-*/bin/standalone.sh

Time Series Forecasting Library `hawkular-datamining-forecast`

All models uses non-linear optimization algorithm to estimate best parameters of the model. Models and Forecasters are designed for online learning.

Simple, Double, Triple exponential smoothing models
AutomaticForecaster - which automatically selects the best model, selection is based on AIC, AICc, BIC
Simple moving average (Weighted moving average)
Augmented Dickey-Fuller test
Autocorrelation function (ACF)
Time series decomposition
Time series lagging
Time series differencing
Automatic period identification

Enable prediction in Hawkular

In Hawkular prediction can be enabled directly in UI by increasing forecasting horizon or through REST call by creating Relationship from Tenant to Metric, MetricType or Tenant.

Following example enables forecasting for all metrics under given tenant.

$ tenant=$(curl -s GET 'http://jdoe:password@localhost:8080/hawkular/inventory/tenant'| grep --color=never -oP 'path" : "\K/t;[0-9a-z\-]+')
$ curl -ivX POST -H "Content-Type: application/json" 'http://jdoe:password@localhost:8080/hawkular/inventory/tenants/relationships' -d '{
    "name": "__inPrediction",
    "source": "'$tenant'",
    "target": "'$tenant'",
    "properties": {"forecastingHorizon": 150}
}'

Source and target are canonical paths.
