Hi Alessandro,
Thanks Again.
After adding host and MySQL Datasource in conf/server.xml, when I started Knowage server it is giving memory error as shown below.
INFO: Deploying web application archive /home/ubuntu/knowage/destination/Knowage-Server-CE/webapps/knowagewhatifengine.war

Hi,
JAVA_HOME error was fixed by adding forward slash (JAVA_HOME="/usr/lib/jvm/java-8-oracle/"). My Bad.
Now when I am starting Knowage server, I can see errors in logs and http://<MyIPAddress>:8080/knowage/<http://%3cMyIPAddress%3e:8080/knowage/> is not working.
I followed https://www.knowage-suite.com/qa/548/not-able-to-start-knowage-server and tried changing hazelcast port but still same error.

Hi,
first of all you could use the latest release, which is 6.2.0-RC that we just released.
Also, to install it without the GUI, please use the -c option: sh Knowage-6_1_1-CE-Installer-Unix-20171213.sh -c

Thanks Alessandro,
Need your guidance for installation and setup of Knowage with MySQL.
I am using Ubuntu 16.04 (Linux ubuntucustomfiware 4.4.0-119-generic #143-Ubuntu SMP Mon Apr 2 16:08:24 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux).
I have already installed MySQL.
For Knowage, I downloaded zip file from http://download.forge.ow2.org/knowage/Knowage-6_1_1-CE-Installer-Unix-20171213.zip
After unzipping it, there is a .sh file.
On running this .sh file I am getting following error.

Dear Krishan,
you can exploit Knowage with MySQL, CKAN, and several other datasources: Oracle, SQL Server, HSQL, MySQL, PostgreSQL, Ingres, DB2, AS400, Impala, Hive, Cassandra, SparkSQL.
You can also exploit data directly from the Context Broker as well as with a REST service or a simply CSV/XLS file.
You can have a look at the PDF version of our community documentation, which BTW I'm happy to say that will be published also on readthedocs in a really short time.

Hi Juanjo,
In initial understanding of 'Knowage', it seems it works with CKAN. Am I right?
Actually, I was using MySQL with Cygnus, so is it possible to use Knowage MySQL?
I tried using CKAN with Cygnus but on installing CKAN (http://docs.ckan.org/en/ckan-2.7.3/maintaining/installing/install-from-source.html#install-the-required-packages) I am getting following issue.
[cid:image005.png at 01D3EE0C.7001A2D0]
Please suggest.

Subject: Re: [Fiware-tech-help] How to fetch historical data?
Dear Krishan,
GUIs of applications tend to be tailor-made. Nevertheless, I will try to give you some hints that I hope can be useful:
* Knowage<https://github.com/KnowageLabs/Knowage-Server> is a very complete business intelligence tool that comprises many functions including those for producing reports on historic data which has beeen stored in data-sinks using Cygnus. It also include some functions for creating dashboards.
* Operational dashboards which query directly on the Orion Context Broker or some other data services can also be based on Wirecloud<https://github.com/Wirecloud/wirecloud>.
* STH-Comet<https://github.com/telefonicaid/fiware-sth-comet> can be used to store raw and aggregated time series context information in MongoDB which then you can get access to using an API
* You can also use QuantumLeap<https://smartsdk.github.io/ngsi-timeseries-api/> for transferring historic data into time series databases and then use some GUI tools for visualizing data (e.g., Grafana). This is useful is some use cases.
I add people from the Eng and FICodes teams in case they want to add something regarding Knowage and Wirecloud.
Let us know if these hints bring answer to your questions.
I would like to take advantage of this mail to let you know that we have re-structure contents of the FIWARE developers' page<https://developer.fiware.org/> and the FIWARE Catalogue<https://www.fiware.org/developers/catalogue/>. We will continue working on improving it based on feedback.
Cheers,
Juanjo

Subject: How to fetch historical data?
Hi Jose,
Thanks for all your support so far.
I have setup Cygnus with MySQL agent and now data is storing into MySQL.
As a next step, we need to show reports of historical data (Saved in Cygnus_MySQL) in GUI. It may be based upon some filters like data for today, last week/month, area wise etc.
My questions are
1. Do we need to create our own APIs for fetching data from MySQL and returning to GUI application?
2. Or is there any GUI component (WireCloud or any other) in which we can directly fetch Cygnus Data? Or we need to create our custom GUI ourselves?
3. I found a component STH-Comet (https://github.com/telefonicaid/fiware-sth-comet), will it fit in our requirements for fetching Cygnus_MySQL data?
4. Do let me know if Fiware have any other components matching with our requirement.
Thanks & Regards,
Krishan Babbar
