Meteo

Meteo is a realtime event processing engine. It can get time series data from a variety of sources and leverages Esper to do runtime analysis. Meteo can output data to different rendering engines for graphing purposes.

Listeners

Meteo can currently take data from:

  • Flat files

  • Netezza

  • ActiveMQ

  • JMX

Publishers

Meteo can currently publish data to:

  • Flat files

  • Arecibo

  • Graphite

  • OpenTSDB

  • Reconnoiter (via Resmon)

Build

mvn clean install

Run

java -Drt.configFile=rt_conf.json -Drt.esper.configFile=esper_conf.xml -Xmx4096m -Xms2048m -jar metrics.mateo-1.0.1-jar-with-dependencies.jar

Configuration

Publisher and listeners

This configuration file contains sample configurations for all currently defined publisher and subscriber types plus sample Esper statements:

Esper

All events that esper should process, need to be declared in the esper configuration file beforehand. A sample configuration file looks like this:

<esper-configuration xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                     xsi:noNamespaceSchemaLocation="esper-configuration-1-0.xsd">
    <event-type name="PerfEvent">
        <java-util-map>
            <map-property name="html_time" class="long"/>
        </java-util-map>
    </event-type>
    <event-type name="LoadAverage">
        <java-util-map>
            <map-property name="timestamp" class="long"/>
            <map-property name="SystemLoadAverage" class="long"/>
        </java-util-map>
    </event-type>
    <plugin-aggregation-function name="tp" function-class="com.ning.metrics.meteo.esper.TPAggregator"/>
    <plugin-view namespace="ning" name="predict"
                 factory-class="com.ning.metrics.meteo.esper.HoltWintersViewFactory"/>
</esper-configuration>
