Short MIIMETIQ definition
Last months in M2M Cloud Factory we have been working on MIIMETIQ. Last weeks I’ve been thinking about how to define MIIMETIQ shortly and this is my definition, please tell if you can understand something. Of course, you have to know we’re focused in Internet of Things and M2M market.
- MIIMETIQ is an IoT/M2M framework, so this is the first step to setup to develop your vertical solution.
- Framework: With a well defined architecture a framework is a set of functions ready to create any application. Everything else is open and adaptable.
- MIIMETIQ architecture is service oriented and it uses AMQP as a message broker to connect the services.
- MIIMETIQ has several modules, we define a module as a set of services. Basicly MIIMETIQ have 5 modules:
- Identity Manager: manage users, groups, roles and all kind of entities the project needs and its security.
- Assets Manager: a data model manager, the integrator creates the business logics and data models here.
- Distribution System: this is a set of agnostitc connectivity layers to different types of devices.
- A E N M: several time series and other signals flow through the AMQP, this data are events and using rules those events could be converted in alarms and some alarms have to be notified to proper services, systems or people.
- Control Panel UI: this is an administration dashboard, in form of a UI to setup and monitor the most common uses of MIIMETIQ.
- Using those modules usually the integrators create their own user interface to satisfy customer requiremests. In M2MCF we create those UI using ADUX (Advanced Development User Experience).
- After configuring MIIMETIQ the integrator has 2 customized APIs to connect their code with MIIMETIQ. One of them is an API REST and another one is AMQP.
- Finally everything inside MIIMETIQ could be customized, because the flexibility is very important when you have an horizontal solution.
Charla sobre MIIMETIQ en la PyConES 2014 de Zaragoza
No son pocas las veces que me preguntan a que me dedico. Pues bien, la charla “light” que he dado este mediodia en Zaragonza en el marco de la PyConES 2014. Una charla de 10min más preguntas me ha permitido compartir con la comunidad cuál es la ocupación que me ha tenido ocupado la mayor parte de mi tiempo durante este año. Cómo CTO de M2M Cloud Factory, he tenido la suerte de poder proponer la arquitectura que con la ayuda de mis compañeros hemos desarrollado. Se trata de un framework para el desarrollo de aplicaciones M2M bautizado con el nombre de MIIMETIQ.

Conferència al Tecnocampus: Internet of Things (IoT) low cost
Després d’arribar corrent de Cardiff on era aquest dilluns el dimarts vaig arribar a temps per fer la presentació “Internet of Things low cost” als companys del Tecnocampus de Mataró; per cert, unes intal·lacions brutals res a veure amb la EUPMT on vaig estudiar jo fa una colla d’anys. Jo encara diria més, molt millor que no pas la gran Universitat de Cardiff on vaig ser el dilluns.
Pel que fa a la xerrada agraïr a tothom que hi va assistir, a continuació adjunto les transparències pels que vareu ser-hi i pels que no.
Properament pujaré el video, o la part, del video que es va poder gravar. El problema és que són diversos gigues i he de deixar l’ordinador renderitzant cosa que encara no he pogut fer.
El video no conté tota la presentació però té una part important del contingut, així que desitjo que ús sigui útil:
Per cert, una gran part de la presentació esta reciclada de la conferència: Conferència: La revolució dels mini-PC: Raspberry PI, Arduino i més
OpenAM: some ssoadm commands for reference
OpenAM is as much powerful as complicated sometimes. In this case I spent a lot of time understanding how to set simple settings because of that I decide to take note about that in this blog entry.
First of all don’t forget to set the environment variables and go to ssoadm path:
export JAVA_HOME="/usr/lib/jvm/java-6-openjdk-amd64/jre" export CLASSPATH="/var/lib/tomcat7/webapps/openam/WEB-INF/lib/policy-plugins.jar::/var/lib/tomcat7/webapps/openam/WEB-INF/lib/openam-core-11.0.0.jar"
cd /opt/openam/ssoadmin/openam/bin
Getting the list of user identities:
./ssoadm list-identities -u amadmin -f /tmp/oam.pwd -e / -t User -x "*"anonymous (id=anonymous,ou=user,dc=openam)
demo (id=demo,ou=user,dc=openam)
serviceusername (id=serviceusername,ou=user,dc=openam)
amAdmin (id=amAdmin,ou=user,dc=openam)
Search of Identities of type User in realm, / succeeded.
another useful query would be:
./ssoadm list-identities -u amadmin -f /tmp/oam.pwd -e / -t Role -x "*"No plug-ins configured for this operation
But as you can see it doesn’t work and I don’t know how to solve it.
Taking a look to GUI get to identities list with: Access Control > / (Top Level Realm) > Privileges
In this webpage you have a list of role identities, in my case I have only this: “All Authenticated Users”. Inside this identity I can set different privileges:
- REST calls for Policy Evaluation (EntitlementRestAccess)
- Read and write access to all log files (LogAdmin)
- REST calls for searching entitlements (PrivilegeRestReadAccess)
- Read access to all log files (LogRead)
- Read and write access to all federation metadata configurations (FederationAdmin)
- Read and write access only for policy properties (PolicyAdmin)
- Read and write access to all configured Agents (AgentAdmin)
- Read and write access to all realm and policy properties (RealmAdmin)
- REST calls for managing entitlements (PrivilegeRestAccess)
- Write access to all log files (LogWrite)
If we want to remove a privilege:
root@vm:/opt/openam/ssoadmin/openam/bin# ./ssoadm remove-privileges -u amAdmin -f /tmp/oam.pwd -e / -g EntitlementRestAccess -i "All Authenticated Users" -t role Privileges were removed from identity, All Authenticated Users of type, role in realm, /.
or adding a privilege:
root@vm:/opt/openam/ssoadmin/openam/bin# ./ssoadm add-privileges -u amAdmin -f /tmp/oam.pwd -e / -g EntitlementRestAccess -i "All Authenticated Users" -t role
Talking about policies, exporting:
./ssoadm list-policies -u amadmin -f /tmp/oam.pwd -e / -o /tmp/policies.xml
and if we want to import the policies:
./ssoadm create-policies -u amAdmin -f /tmp/oam.pwd -e / --xmlfile /tmp/policies.xml
creating a user:
./ssoadm create-identity -u amadmin -f /tmp/oam.pwd -e / -i serviceusername -t User --attributevalues "userpassword=servicepassword"
Useful references:
La excelencia en el servicio
- ATENCIÓN: compuesto por actitud, amabilidad, comprensión, disposición, saber escuchar, comunicación verbal y no verbal, educación y la imagen personal.
- CALIDAD: se podría describir como los requirimientos del producto o servicio, información suministrada, instrucciones recibidas, de lo que se trata es de aportar el máximo beneficio al comprador y tener una buena relación calidad precio. Obviamente hay que cumplir con lo que se ha prometido. Para poder replicar esta calidad son fundamentales los procesos y procedimientos internos que deben estar claramente definidos y se deben cumplir por todos los empleados.
- OPORTUNIDAD: es fundamental ofrecer el servicio o producto en el momento del tiempo que es requerido, nunca después porqué esto sería una perdida de oportunidad.
- COMODIDAD: se trata de darle el máximo comfort al cliente cuando adquiere nuestros productos o servicios. Los típicos ejemplos son el ofrecer parking, pre-reserva de asientos, servicio a domicilio, ventas y atención a distancia, etc.
Python meetup Barcelona presentation: Heating system using Panstamp and Python
Last Thursday I was presenting my home heating system at Python Meetup Barcelona.
