[Fiware-robotics] R: Finish technical issues investigation 10:00 on friday

Hi guys,
In the link https://forge.fiware.org/plugins/mediawiki/wiki/fiware/index.php/Publish/Subscribe_Broker_-_Orion_Context_Broker_-_User_and_Programmers_Guide#Context_subscriptions
We found this interesting explanation about the ONCHANGE notification:
The throttling element is used to specify a minimum inter-notification arrival time. So, setting throttling to 5 seconds as in the example above makes that a notification will not be sent if a previous notification was sent less than 5 seconds ago, no matter how many actual changes take place in that period. This is to not stress the notification receptor in case of having context producers that update attribute values too frequently. Actually, throttling is not an "exclusive" field for ONCHANGE subscriptions: from a theoretical point of view it can be used in ONTIMEINTERVAL subscriptions but, given that in that case you can precisely control the notification frequency it doesn't have any practical sense.

It seems to me that you set PT10S on FIROS, that's 10 second, indeed if we try every 10 seconds the turtle is moved correctly.
Let us know if we miss something and above all if this solve the problem, maybe you can decrease the number of seconds or unset the parameter if possible.
Roberto

Hi Angel,

can you check the webapp (http://130.206.127.115/demo1/) to enable me to do some test this afternoon?
It seems that the FORWARD button passes through "http://soc-e.noip.me:10101/NGSI10/updateContext" that is not more available now.

I think Roberto will not be available tomorrow morning but if it is a firewall problem I think it will automatically disappear for the next demo (we will use another machine and we also release you the RCM).

Let me known for the web-app
D

Hi all,

We'll be available at 12:30, we'll you be available at that time?

We've been searching in contextBroker's log and found many connection time out related to TI's IP:
E:Monday 02 Feb 11:29:19 2015(715):contextBroker-/clientSocketHttp.cpp[97] socketHttpConnect: connect(188.15.109.226, 10100): Connection timed out

Hi Angel and All,

You didn't miss it, it's just that I didn't create yet (well, I didn't share it...) the doc link, here it is:
https://docs.google.com/document/d/1lz7_vtnLCkLSNCVd_AlPrwlh8UzBV_ygUoxLNvgN9KM/edit?usp=sharing

I have put few instructions, plus my simple ideas I shared in the last call we had.

All the team is invited to contribute to this document with ideas/proposals: I really would like you use this as a place where opinions, proposals, ideas, can be freely shared (even very challenging solutions!).
So use it as a working document, you can provide new text, pictures, etc and drop others; for this last point (dropping parts) since google docs is not very good at showing changes, it would be preferable marking unwanted parts as obsolete (e.g. with different color), so we can keep track more easily of what we have decided.

All what contributed will be helpful to draw at the end a synthesis that we'll propose to the live demo group.

For what concerns the demo issues I'm in favour to analyse them as well.

We'll get in touch later in the I2ND call.

BR
Pier

Morning Pier,

I am not sure if I missed it, but have you shared the brainstorming document for the live demo e talked about?

Please let me know if you need any help with that.

Also, do you guys want to keep investigating the network issues we experienced on Monday?

Let us know if you want to do it over a hangouts session or so.
Thank you,
