How to check if JBoss is running?

Ensuring that your WildFly server is up and running is essential for maintaining the health and availability of your applications. This article will guide you through various methods to check if your WildFly server is running.

Starting the server and checking the status

When you start the application server, a set of System Properties are attached to the Java process. This makes easy to detect which Java processes are related to the application server:

is jboss running?

Therefore, a simple and effective strategy is to check the list of processes and grep for ‘jboss’:

ps -ef | grep jboss | grep -v grep

You can also check the server status through the HTTP public address and port with any tool like curl:

curl -s http://localhost:8080 | grep WildFly

    <title>Welcome to WildFly</title>
                <img src="wildfly_logo.png" alt="WildFly" border="0" />
        <h1>Welcome to WildFly</h1>
        <h3>Your WildFly instance is running.</h3>

In some environment, for example Cloud environment, you might have only a limited set of commands. However, the jps command line is available upon JDK installation. Therefore, you can use the jps command to check the server status.

In the following example, we are storing the PID of a JBoss/WildFly server in the PID environment variable:

PID=$(jps -lv | grep -i jboss | cut -d ' ' -f 1)

If you need a file system method to check the server status, then you can check within the $JBOSS_HOME/standalone/tmp folder. When the server is running, you will find the startup-marker file in there:

ls -al /home/jboss/wildfly-26.0.1.Final/standalone/tmp
total 4
drwxr-xr-x. 1 francesco francesco 106 Feb 22 15:44 .
drwxr-xr-x. 1 francesco francesco  74 Feb  1 16:00 ..
-rw-rw-r--. 1 francesco francesco  21 Feb 22 15:44 startup-marker
drwxrwxr-x. 1 francesco francesco  28 Feb 22 15:44 vfs

When the server stops, the startup-marker file will be removed.

How to check WildFly status from the CLI

You can check JBoss / WildFly status from the CLI in different ways. If you are running in standalone mode, then you can just execute an “ls” command from the server root:

You can also fetch the server state in a no-interactive way. For example:

/ -c --commands=":read-attribute(name=server-state)"

Then, if you are running WildFly in Domain Mode, you need to reference your Host Controller to read the status attribute. For example:


Finally, if you go do a grep on the Server logs, you can check both the server status and the list of applications deployed:

cat ../standalone/log/server.log | grep WFLYSRV

Monitoring your WildFly application server is crucial for ensuring the smooth operation of your applications. By using the methods outlined in this article, you can easily verify if your WildFly server is running. Whether you prefer using log files, command-line tools, the Management Console, or automated scripts, these techniques will help you keep your server in check and maintain its reliability.
