2017-01-10 15:08:24 +0100 answered a question NullPointerException in DoSAttack2 example with CEP

Same problem is reported and discussed over stackoverflow here: http://stackoverflow.com/questions/41... This issue will be managed there, so this particular item is closed.

2017-01-10 14:55:34 +0100 answered a question How to send event in Orion (version 2) with CEP

ORION does not support XML format anymore, use JSON only. CEP Proton latest release supports both protocols though.

2016-10-05 14:42:25 +0100 answered a question Can PROTON CEP deal with such a case (or is it impossible?) where it's required to dynamically add/edit/delete rules made by hundreds of users while the CEP is running?

PROTON doesn't allow for concurrent editing of the rules. The rules that belong to a single application reside in a single JSON file. From experience, even in large applications, this file is not so large. In any case, it is not intended for hundreds of users simultaneously entering their rules. Thru the authoring tool it is possible to quite easily get to the desired rule in the JSON file, but the editing is always on the JSON file that encompasses the entire event-driven application.

In addition, a json rules file can be reloaded to be re-edited multiple times with a Proton server, and saved in a user storage space.

Hope this helps.

2016-09-27 14:03:46 +0100 answered a question What are the technical requirements of an Context Broker and an Complex Event Processing?

Per CEP: The Fiware CEP GE is the Proton (Proactive Technology Online) asset by IBM. It runs as a web application, on a platform such as Tomcat. The hardware requirements for the platform to would be at least 8GB Ram. Clients post events to this service and complex situations it detects are emitted according to the rules coded into it using a web interface. No programming skills are needed, yet clients need to implement RESTful calls with Json, XML or free text payloads to represent the events. When intensive stream of events needs to be handled, you can use a variation of Proton which is integrated with STORM.

Hi, In fact, when we talk about events, we mean discrete events, each with its time-stamp. Hence, the question may refer to the methodof flowing the events into CEP. In this regard, I suppose you mean that REST calls being "discrete", while a streaming facility such as STORM would mean what you really ask about. Indeed, Proton CEP has a version that work over STORM for that purpose. The artifacts for that are in github: https://github.com/ishkin/Proton/blob.... I will follow up on this comment regarding the specific installation/configuration details for the STORM adapter of Proton. Thanks, - Uri

2016-04-25 08:59:17 +0100 answered a question Proton image not available at Dockerhub

Answer is explained in the last comment. In any case, a new Docker image and Docker creation process are explained in the project's git folder for that: https://github.com/ishkin/Proton/tree... Thanks.

We have a help request of exact question already as HELP-6111: http://jira.fiware.org/browse/HELP-6111 Will mark this as duplicate.Thanks.

2016-03-18 09:52:27 +0100 commented question Proton image not available at Dockerhub

This issue has been solved in two ways: 1. The Dockerfile has been simplified and unified with the puppet procedure so that all is done according to the same flow. 2. The image has been pushed to the docker hub. There is still a problem with tomcat initialization with an interim fix published.

2016-03-18 09:52:26 +0100 commented question Proton image not available at Dockerhub

Good question. Should do that. While it is convenient to get the docker image from here, it is equaly available form the github. You can pull it from there with svn to avoid a full cloning of the asset resources, like so: svn checkout https://github.com/ishkin/Proton/trunk/docker Thanks.

2016-03-18 09:52:26 +0100 commented question Proton image not available at Dockerhub

Also: There are some issues at work with that image so when that is fixed, we will push the image also to dockerhub. - Uri
