In which platforms has been Sentilo tested ?¶
The first deployment for the Barcelona City Council has been tested in the following infraestructure:
- Four virtual machines, two for the front-ends and another two for the back-end
- All of them use as operating system Ubuntu server LTS 16.04
- The real time database server(Redis) works with 32 GB of memory and 36 GB of hard disk
- The other three servers works with 4 GB of memory and 16 GB of hard disk
Another deployment configuration should work properly, always keeping in mind the expected load by the system. There is also a virtual machine ready for use that can be used for testing purposes.
I successfully published an observation, but I cannot see the data in catalog.¶
Check that the Catalog and Sentilo API Server are in the same timezone, for example in UTC. Make sure the sentilo-server is executed with the following VM option:
Also, make sure that the Tomcat that hosts the Catalog application has the same option, for example en $JAVA_OPTS variable.
Maps is not showing up in Catalog application¶
You can define the API key inside the sentilo/sentilo-catalog-web/src/main/resources/properties/catalog-config.properties configuration file:
# Google API key to use Google Maps google.api.key=<your key>
Remember you’ll have to recompile sentilo-catalog-web redeploy the sentilo-catalog-web.war after that.
I created a provider and immediately after that, an observation using the new provider’s token is rejected with 401 “Invalid credential”¶
The providers are activated in a background job that runs every 5 minutes. Please wait a moment :-)
Another possible reason is that the Sentilo API server started before the Catalog application (probably deployed on your Tomcat). At startup, the API server performs a call to /sentilo-catalog-web/api/entities/permissions in order to mirror the permissions stored in MongoDB with Redis. If this call fails because the sentilo-catalog-web is not deployed yet, the permissions are not correctly created. To resolve the issue, reboot your Sentilo and ensure that the API server starts always after the sentilo-catalog-web is fully deployed.
The command mvn package appassembler:assemble fails.¶
You have to execute the command in the directory of the component you want to install.
I think I installed Sentilo. How can I confirm all is up & running?.¶
You can use this script:
