Displaying Camel Context information in Karaf

Karaf can display detailed information about individual Camel Contexts deployed in the container using the camel:context-info command. Context-wide statistics, behaviors, contained components, and more can be discovered using this command.

Getting ready

Follow the instructions in the Listing Camel Contexts in Karaf recipe's Getting ready section for this recipe.

How to do it…

Use the following camel:context-info command on the Karaf console to retrieve context information—a small warning, there may be a lot of output generated:

karaf@root()> camel:context-info CamelCommandContext 

The output will be as follows:

The preceding camel:context-info invocation demonstrates that a large quantity of data is available about each context; it is not uncommon for users to capture this output for analysis.

How it works…

The context-info command hooks into Camel's own facilities to access context information. Upon retrieval, the data is then formatted for display on Karaf's console.
