In this recipe, we will learn how to check the state of a running WildFly instance, by invoking a command to the CLI.
Remember I'm running WildFly remotely, bound to 192.168.59.103
as IP. WildFly is already up and running.
Open a new terminal window and execute the following:
$ cd $WILDFLY_HOME $ ./bin/jboss-cli.sh -c --controller=192.168.59.103:9990 --user=wildfly --password=cookbook.2015 --command=":read-attribute(name=server-state)" { "outcome" => "success", "result" => "running" }
You can extract just the information you need by using the awk
command in the output (you can use whichever tool you are comfortable with), as follows:
$ ./bin/jboss-cli.sh -c --controller=192.168.59.103:9990 --user=wildfly --password=cookbook.2015 --command=":read-attribute(name=server-state)" | awk 'NR==3 { print $3 }' "running"
In case you are running WildFly in the domain mode, the invocation is as follows:
$ ./bin/jboss-cli.sh -c --controller...
