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.

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>
For more info see esper.codehaus.org/esper-4.2.0/doc/reference/en/html/configuration.html#configuration-via-xml
There is a REST interface one can use to upload streams at runtime. For instance, if newStream.json is:
{
"name": "Counts",
"sql": [
"select count(*) as count from Visit.win:time(1 sec) "
],
"routes": [
{
"name": "Jansky",
"filters": [ "count" ]
}
]
}
One can add it at runtime by POSTing it to /rest/1.0:
curl -v -XPOST http://127.0.0.1:8080/rest/1.0 -H'Content-type: application/json' [email protected]
Meteo ships with a special publisher (com.ning.metrics.meteo.publishers.ResourceListener) to expose data over HTTP (jsonp). This is useful for graphing purposes (see github.com/pierre/metrics-dashboard for an example on how to use it with d3.js).
To use it, you need to add it as a publisher and configure a stream appropriately:
"publishers": [
{
"name": "Jansky",
"type": "com.ning.metrics.meteo.publishers.ResourceListener",
"@class": "com.ning.metrics.meteo.publishers.ResourcePublisherConfig"
}
],
"streams": [
{
"name": "Visitors",
"sql": [
"select sourceIpAddress as ip from Visit.win:time(1 sec)"
],
"routes": [
{
"name": "Jansky",
"filters": [ "ip" ]
}
]
}
]
You can now access the data via the /rest/1.0/{stream_name}/{esper_attribute} endpoint, e.g.:
curl http://127.0.0.1:8080/rest/1.0/Visitors/ip ; echo
