In this recipe, you will learn how to get the JVM WildFly is running with 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 commands:
$ cd $WILDFLY_HOME $ ./bin/jboss-cli.sh -c --controller=192.168.59.103:9990 --user=wildfly --password=cookbook.2015 --command="/core-service=platform-mbean/type=runtime:read-attribute(name=spec-version)" { "outcome" => "success", "result" => "1.8" }
Obviously, 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="/core-service=platform-mbean/type=runtime:read-attribute(name=spec-version)" | awk 'NR==3 { print $3 }' "1.8"
