camel-log: Demonstrates how to use logging with Camel
======================================================
Author: Fuse Team  
Level: Beginner  
Technologies: Camel  
Summary: This quickstart shows a simple Apache Camel application that logs a message to the server log every 5th second.  
Target Product: Fuse  
Source: <https://github.com/jboss-fuse/quickstarts>  

This example is implemented using solely the XML DSL (there is no Java code). The source code is provided in the following XML file `src/main/resources/OSGI-INF/blueprint/camel-log.xml`, which can be viewed from [github](https://github.com/fabric8io/fabric8/blob/master/quickstarts/beginner/camel-log/src/main/resources/OSGI-INF/blueprint/camel-log.xml).

This example uses a timer to trigger every 5th second, and then writes a message to the server log, as shown in the figure below:

### Building this example

The example comes as source code and pre-built binaries with the fabric8 distribution. 

To try the example you do not need to build from source first. Although building from source allows you to modify the source code, and re-deploy the changes to fabric. See more details on the fabric8 website about the [developer workflow](http://fabric8.io/gitbook/developer.html).

To build from the source code:

1. Change your working directory to `quickstarts/beginner/camel-log` directory.
1. Run `mvn clean install` to build the quickstart.

After building from the source code, you can upload the changes to the fabric container:

1. It is assumed that you have already created a fabric and are logged into a container called `root`.
1. Change your working directory to `quickstarts/beginner/camel-log` directory.
1. Run `mvn fabric8:deploy` to upload the quickstart to the fabric container.

If you run the `fabric:deploy` command for the first then, it will ask you for the username and password to login the fabric container.
And then store this information in the local Maven settings file. You can find more details about this on the fabric8 website about the [Maven Plugin](http://fabric8.io/gitbook/mavenPlugin.html).

## How to run this example

The following information is divded into two sections, whether you are using the command line shell in fabric, or using the web console

### Using the command line shell

You can deploy and run this example at the console command line, as follows:

1. It is assumed that you have already created a fabric and are logged into a container called `root`.
1. Create a new child container and deploy the `quickstarts-beginner
quickstarts/beginner/-camel.log` profile in a single step, by entering the
 following command at the console:

        fabric:container-create-child --profile quickstarts-beginner
quickstarts/beginner/-camel.log root mychild

1. Wait for the new child container, `mychild`, to start up. Use the `fabric:container-list` command to check the status of the `mychild` container and wait until the `[provision status]` is shown as `success`.


### Using the web console

You can deploy and run this example from the web console, as follows

1. It is assumed that you have already created a fabric and are logged into a container called `root`.
1. Login the web console
1. Click the Wiki button in the navigation bar
1. Select `quickstarts` --> `beginner` --> `camel.log`
1. Click the `New` button in the top right corner
1. In the Create New Container page, enter `mychild` in the Container Name field, and click the *Create and start container* button


## How to try this example

The following information is divded into two sections, whether you are using the command line shell in fabric, or using the web console

### Using the command line shell

To use the application be sure to have deployed the quickstart in fabric8 as described above. 

1. Log into the `mychild` container using the `fabric:container-connect` command, as follows:

        fabric:container-connect mychild

1. View the container log using the `log:tail` command as follows:

        log:tail

To exit the tail logger, press Ctrl-D. And to logout from the `mychild` container, then use the `exit` command, which returns back to the `root` container.

### Using the web console

This example comes with sample data which you can use to try this example

1. Login the web console
1. Click the Runtime button in the navigation bar
1. Select the `mychild` container in the containers list, and click the *open* button right next to the container name.
1. A new window opens and connects to the container. Click the *Log* button in the navigation bar.
1. You can also click the *Camel* button in the top navigation bar, to see information about the Camel application. For example in the Camel tree, select the Camel route `log-example-context`, and click the *Diagram* button in the sub navigation bar, to see a visual representation of the Camel route.


## Undeploy this example

The following information is divded into two sections, whether you are using the command line shell in fabric, or using the web console

### Using the command line shell

To stop and undeploy the example in fabric8:

1. Disconnect from the child container by typing Ctrl-D at the console prompt.
1. Stop and delete the child container by entering the following command at the console:

        fabric:container-stop mychild
        fabric:container-delete mychild

### Using the web console

To stop and undeploy the example in fabric8:

1. In the web console, click the *Runtime* button in the navigation bar.
1. Select the `mychild` container in the *Containers* list, and click the *Stop* button in the top right corner
