The DEBS 2012 Grand Challenge problem involves monitoring of The goal of the Grand Challenge was to provide queries to monitor large hi-tech manufacturing equipment. The overall goal of the challenge is to demonstrate the capability of the event processing system to solve the set of queries for the given data. Therefore, the problem description is divided into two major parts - the description of the available data and the description of the queries which need to be executed on the data in order to solve the problem.
Monitoring data is recorded by the manufacturing equipment itself using an embedded PC and a set of sensors. The data is recorded with 100Hz frequency. However, it is possible that the time between two consecutive data points differs significantly from 10ms. The data is available as a flat CSV file, with each line representing a single event (data point). For the convenience of the DEBS Grand Challenge participants we have provided a data generator. The data generator is a simple runnable 32-bit JAR file which consumes the CSV data file and puts its contents into events which are subsequently sent via TCP/IP to a scpecified destination address. The generator JAR file can be downloaded from this link. The generator outputs (serializes) events in Google Protocol Buffers format. We also provide source code for a very simple server capable of receiving the messages output by the generator. The schema of output events is the following:

The only difference between the event schema output by the generator and the event schema in the CSV file is that for the generator output the time stamp format is converted from the ISO-like representation into the UNIX-like representation - seethe above schema definition. In order to run the generator a following command has to be issued:
$ java -jar generator.jar "/path/to/data/file.dat" 1.0 localhost 8080Our Paper can be found here: https://dl.acm.org/doi/10.1145/2335484.2335523
