I want to connect to MongoDB by GUI manager e.g 3T MongoChef, MongoDB Compass,Robomongo,MongoBooster.
I use windows.
How to connect with mongoOrion database by GUI manager?
As far as I understand (althoug I don't know 3T MongoChef, so I may be wrong) MongoChef is expecting the URL of a MongoDB endpoint. However, you have provided the URL of the Orion Context Broker endpoint (i.e. the NGSI REST API).
You should use the URL endpoint correspondign to the MongoDB instance used by Orion. By default Orion uses the MongoDB instance running at localhost (i.e. the same host where Orion runs) on default mongo port (i.e. 27017). That default can be overriden using the -dbhost CLI parameter.

I need to access a postgres database from my java code which resides in openshift cluster. I need a way to do so. without initiating port forwarding manually through oc port forward command.
I have tried using openshift java client class openshift connection factory to get the connection by passing server url and username password through which I log in to the console but it dint help.
(This is mostly just a more detailed version of Will Gordon's comment, so credit to him.)
It sounds like you are trying to expose a service (specifically Postgres) outside of your cluster. This is very common.
However the best method to do so does depend a bit on your physical infrastructure because we are by definition trying to integrate with your networking. Look at the docs for Getting Traffic into your Cluster. Routes are probably not what you want, because Postgres is a TCP protocol. But one of the other options in that chapter (Load Balancer, External IP, or NodePort) is probably your best option depending on your networking infrastructure and needs.
I am new to FIWARE. I managed to install Orion Context Broker on my local system following the steps mentioned in the FIWARE website. I am able to use CURL commands to create entities and also retrieve values.
I have also installed Wirecloud on my local system and able to access Wirecloud UI from my browser.
But I am unable to display the entities on the Wirecloud widgets. I have tried all widgets including "NGSI Type Browser", NGSI Browser and NGSI Source operator.
All returning the same error: "ConnectionError: Unexpected response from WireCloud's proxy"
Please help me on how to proceed. My NGSI-proxy is also running and listening on port 3000. Screenshots attached.

Can you try to replace localhost with IP address of your machine running Orion and Ngsiproxy?
I've recently created a Mule application (3.7.0 CE) on a laptop. I'm connected to an AWS RDS instance when running locally in AnyPoint Studio using Maven. I started with a local MySQL DB and migrated it to AWS because my application "proofofconcept" is just that a proof of concept and I would like to show the application online (public url) instead of my laptop for a presentation. I added the database.url=... property to the application properties when I deployed to Anypoint Runtime Manager in the cloud. I'm currently getting a:
communications link failure
I've tried several things and nothing has worked. I tried a basic database connection first in the database config. And, then I created a JDBC datasource in Spring-beans. Both methods worked locally and in-communication with AWS (remote). When I deploy to Runtime Manager, the application deploys. And, I get the console that's generated runtime by the RAML. When I call a url e.g. api/v1/orders it runs and runs and after timeout provides the communication error.
Does anyone 1) know if the communication is allowed? 2) know how to fix this? I would like to demo the POC online for my client.
Thanks in advance
My issue was with Amazon VPC and the default security group assigned to my RDS instance. By default all outbound activity is set to any protocol and any port for any ip (0.0.0.0/0). Inbound routing, however was specifying only port 3306 but also a custom using-ip that was my home network public ip. I changed the ip specification to be 0.0.0.0/0. This now mean's that any ip can send a request though port 3306 to my Amazon MySQL instance.
I'm writing an application which delivers data from remote devices over an HTTP API. These devices are on a mobile data connection and have limited resources.
I wish to receive custom monitoring data over the HTTP API, relying on the security model designed in the application, and push that data to Zabbix directly (or indirectly) from node.js. I do not wish to use Zabbix Agent on the remote devices.
I see that I can use zabbix_sender to send data to a Zabbix server containing a pre-configured host. This works great. I intend to deliver monitoring data over my custom API, and when received give this data to zabbix_sender inside the server network.
The problem is there are many devices in the field and more are being added all the time.
TL;DR:
When zabbix_sender provides a custom hostname which doesn't exist in Zabbix already, it fails.
I would like to auto-add discovered hosts, based upon new hostnames from zabbix_sender. How would I do this?
Also, extra respect if anyone can give examples of how to avoid zabbix_sender and send data directly from node.js to the Zabbix server. I mean: suggest an NPM package that you have experience using. (Update: Found working node.js package here: https://www.npmjs.com/package/node-zabbix-sender)
Zabbix configuration: I'm learning from Zabbix 2.4 installed in Docker, no custom configuration from this Dockerhub: https://hub.docker.com/r/zabbix/zabbix-2.4/
Probably the best would be to use the Zabbix API to create hosts directly.
Alternatively, you could set up an action and emulate active agent connection, which would make Zabbix create the host via the active agent auto-regstration.
You could also use low level discovery (LLD) to send in JSON, which would result in hosts/items being created, based on prototypes.
In all of these cases you have to wait for one minute (by default) for the hosts to appear in the Zabbix cache, then you can send the data.
Also note that Zabbix 2.4 is not supported anymore, it will receive no fixes - it is not a "long-term support" release.
my school projekt task is to develop Issue tracking System. My imagine:
JavaFX desktop client application + Spring 4 server + MYSQL database
I would like to use JDBC to reach datas. How should I do it? Spring server made the queries and after it, the spring server should send the client the serialized data?
Yes it's possible, though you don't need spring in that scenario.
Jdbc client would connect directly to the database over the network.
You would have to expose your database to public tcp connections, and firewalls would have to allow this too.
Other options:
Use a local database, like sqlite , and sync w central db over https using a tool like symmetricds. This gives you offline capabilty.
create a restful api on the server, and have the client get and set data using http.
