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...
