Introduction

This sample demonstrates how to set up an execution plan with a quartz scheduler based cron window for generating periodic alerts on build failures. 

...

from buildStatisticsStream[isBuildFailed == true]#window.cron("0 0 1 * * * ? ")
select project, productTeam, lastCommitter, count(timeStamp) as totalBuildFailures
group by project
insert into buildFailureStream;

...

1. Open another terminal, go to <CEP_HOME>/samples/producers/http and run the following command:

   ant -Durl=http://localhost:9763/endpoints/buildStatisticsEventReceiver -Dsn=0115

   It builds the http client and publishes the events at  <CEP_HOME>/samples/artifacts/0115/buildStatisticsEvents.txt to the buildStatisticsEventReceiver http endpoint.

2. You can see the events getting received by CEP by the logs in its console . 

from buildStatisticsStream[isBuildFailed == true]#window.cron("0 5 * * * ?")
select project, productTeam, lastCommitter, count(timeStamp) as totalBuildFailures
group by project
insert into buildFailureStream;
