- Getting to know our Editor, Eddie as we call it.
- Learning about the Ibis console.
Eddie is an online code editor based on Codemirror, which has been instrumental in a multitude of browser editor implementations. For example the developer tools in Chrome and Firefox have a Codemirror based editor, or Adobe Brackets, that also uses CM. In the spirit of the IAF, Codemirror is open source. Besides its editing functionality Eddie displays information about framework classes in its Navigator section, and insert those in the editor. Its third main capability is that it can send its files to an Ibis, thereby creating a back-end service. You can find Eddie at this url . Eddie is tested in Chrome so any ‘strange’ behaviour could be solved by switching browsers.
The Ibis console
An integral part of an Ibis is its console. It is a visual tool that gives feedback about the working of the Ibis. Since an Ibis is all about incoming and outgoing messages we can find information about how much messages have been processed, the content of those messages, their processing status, operations speed, etc. Keep in mind that we are dealing with a tool that can process thousands and thousands of messages. That makes it vital to monitor and test our messages. You can reach the console at this url
|The status window shows the general health of the adapters in the Ibis. Red, green and orange coloring give the user an intuitive grasp of where the attention should go. An Ibis usually has some built in adapters, for example those that manage interaction with the database. Adapters are ordered into tab-groups. For the purposes of this course, you have an own tab, in this case the user should look under the Ibis9 tab. In the example on the right you see a possible error message. For a discussion of those look at our troubleshooting page.|
|The configuration window shows you the code of all the adapters that reside in your Ibis. Under the subtab “manage configurations” you can download the configuration that is currently active. This will give you the same zip file that you will get in Eddie via the load configuration button.|
|Under this tab you can test a specific adapter. In the input field you can enter the message. Usually you will enter some xml or json but you can also upload a different file. The response as it comes back gives you an error or a success message.|
|In Ibis4Education you could need the scheduler. It is a functionality that does things that have to be done on a regular basis. You could think of cleaning up the database. These tasks run automatically. In our Ibis there’s a running task “CheckReload”, that reloads the Ibis when its configuration has changed. This happens every minute, so it could happen that you’ve uploaded your configuration and nothing happens. You can wait then for a minute, or trigger this task by hand.|
|The database can be reached under the tab “jdbc”, standing for Java Database Connectivity. You can browse a table here, or do a query, like creating a table, inserting a document, or inspecting a table. The used sql dialect here is MySql.|
|When you need more detail of a pipeline you can consult the Ladybug tool under the testing tab. You can see the exact flow of events here. The scenario you’ll definitely encounter is that things go wrong and you want to know why and how. The troubleshooting page explains you more about Ladybug.|
