I've upgraded to Graylog enterprise edition (free license) to play around with graylog. I'm hoping to forward from one cluster (which is NOT enterprise, and is already ingesting messages), to another cluser (which is enterprise).
I've downloaded graylog-server-enterprise, as well as added the enterprise license to the web api, but when I go to inputs, theres no forwarder input for me to use on the enterprise cluster. Have I missed something? Am I just not seeing it in the inputs dropdown??
I've tried setting up inputs with the same port number as the forwarder, but no luck with that.
There's simply no input for forwarded messages.
What version of Graylog are you using? You must use v3.01 or later in order to have the Forwarder Input available.
Update:
Since it was quite clear on the docs
I didn't install integration plugins, only the enterprise ones.

I have Kafka Streams java Application up and running. I was trying to use KSQL to create simple queries and Use Kafka Stream for complex solution. I wanted to run both KSQL and Kafka Streams as
Java application.
I was going to through https://github.com/confluentinc/ksql/blob/master/ksqldb-examples/src/main/java/io/confluent/ksql/embedded/EmbeddedKsql.java. is there any documentation for EmbeddedKsql ? or any working prototype ?
KsqlDb 0.10 has been launched and of the newest features in it is the Java Client.
Please go through - https://www.confluent.io/blog/ksqldb-0-10-0-latest-features-updates/
The KsqlDB server does not have a supported Java API at this time. The project doesn't offer any guarantees of maintaining compatibility between releases.
If you were to run ksqlDB embedded in your Java application then KsqlContext would be the class to play around with. But I'm not sure how up-to-date it is, nor can I guarantee it won't be removed in a future release. I'm afraid there there aren't any documentation or examples to look at, as it's not a supported use.
The only supported way to communicate with ksqlDB is really through its HTTP endpoints. You could still embed the server in your own Java app and talk locally of HTTP, though running them in separate JVMs has many benefits.
We would like to install Cytoscape on a server (Windows or Linux) and allow multiple users to connect simultaneously using a client software. Is this possible, and if so, what are requirements in regards to the server and the client software?
Certainly that's possible. There aren't any particular requirements, but keep in mind that for large networks, Cytoscape likes lots of memory. At any rate, we use X2Go on our Linux servers and it works really well for Cytoscape. Keep in mind, however, that a CytoscapeConfiguration directory will be created in each user's home and that apps and configuration information will be stored there.
I've asked this on Adobe's LR SDK forum, thought I'd ask here as well.
I want to create a plugin for Lightroom 6+ that allows two-way communication to take place between a LR plugin and an iOS app. The iOS device would be on the same local network.
What is the best method of accomplishing this? I was thinking about using LRSocket, this is the most direct method? I assume with this method the iOS app would need to act as the server and the LR plugin would be the connecting client? But, all the documentation and examples I’ve found, regarding general LRSocket usage, imply that localhost is used. This would make direct communication with an iOS device over WiFi impossible if it can only use localhost?
Any information would be appreciated.
I've just started out trying to do the same thing, albeit with an Android app, and run into the same (apparently insurmountable) issue that LrSocket.Bind only seems to be able to bind to the localhost interface.
The only way I can think to get around this is to have an intermediary port forwarder on the LR host OS that forwards traffic between localhost:port and ethernet/wifi:port
You could use ssh on a mac, I guess, and there are port-forwarding applications for Windows (ssh is allegedly coming soon). PassPort (an old application from the XP era still seems to work).
It's a bit....messy, though.
Another option would be to use LrHttp.get (and/or .post), but that's going to have to poll for information, and may be a bit laggy for some requirements.
I need the VPS services for hosting my ASP.NET project.
However, it's not just asp.net hosting, I also need SQL Server, RabbitMq and either my running conrole app or my windows service.
So I read the suggestions to use Amazon Web Services as they provide first year for free.
However when I registered I found that I don't have a clue of where I am:
I don't see the option of creating a virtual machine with Windows
I don't see the option of setting up SQL Server on such the machine
and so on.
So I was wondering whether I'm in the right place?
Please advise if AWS can provide me with what I need or I came to the wrong place?
AWS can provide all that you listed, but you'll need to do some learning on your end.
Basically you create an EC2 instance, and then use RDP to remote into it, and you can install software and configure it to your hearts content - just like it was any other physical server.
If you want to use SQL Server, you'll have the choice of installing it directly on the instance using your own license, or using their 'hosted' version of SQL Server call RDS. You'll need to read about it and decide which option is better for your project - there is no single right way.
Lastly, I will point out that although the 'free-tier' is nice, except for a really small application (i.e. small db on a low traffic website), you may find out the 'free-tier' does not quite give you all the power you need to run a busy application. I would not base your decision on wether or not you should use AWS on how much 'free' stuff you can get. The free-tier is nice for learning, but plan on spending some money for a truly robust solution.
I need IPC between a windows service and a GUI application both written in Delphi 2010. I decided to use named pipe for this.
I built and installed successfully Russell Libby's TPipeServer and TPipeClient components (link).
I followed other answers like this.
But my service received only empty messages from the client. After many test I concluded that I was using those components erroneously, so i don't want to post any code here.
So I'm looking for a valid example about how these components work in order to write/read strings in a named pipe (from client to server and viceversa). Any help is really appreciated, even using other free named pipes components or source codes.
Thank you.
Edit: I need a valid way to pass security check in windows server 2008 / windows vista / windows 7
The Cromis-IPC component by Iztok Kacin is a versatile IPC communication Delphi component utilizing windows named pipes. On the given link is a client/server example, and in the source code of the component is a full example.
The Cromis IPC can be used for process communication within the same computer as well as communication between computers on a network. Permissions are easy to handle when doing communication within the same computer. For a detailed description how to handle permissions, see windows doc Named Pipe Security and Access Rights.
