JBoss Application Server (JBoss EAP) is a widely used open-source Java application server designed to build, deploy, and manage enterprise-grade applications efficiently.
Using Site24x7, you can gain deep visibility into your JBoss environment by monitoring server health, JVM performance, and resource utilization across your application servers. With real-time insights into JVM memory, CPU usage, thread pools, data source connections, deployed applications, and transaction metrics—along with instant alerts—you can quickly detect performance bottlenecks, troubleshoot issues, and ensure optimal application performance.
Supported JBoss versions
Enterprise: JBoss EAP 6+
Community: JBoss AS 7 and WildFly 8+
Prerequisites
Note
JBoss Version 7.x and above (EAP version 6 and above)
Navigate to Plugins > Enterprise Applications > JBoss and click the + icon.
On the Add JBoss page, add an On-Premise Poller or choose from an existing one.
Note
JBoss monitoring is supported from Poller version 6.8.2 and above.
On the Add JBoss Monitor page, provide the following details:
Display Name: Provide a name to identify the JBoss monitor in Site24x7.
Host Name/IP Address: Enter the hostname or IP address of the JBoss server.
Port: Specify the management port (default: 9990) used to access the JBoss admin console and CLI.
Domain Mode: Select whether JBoss is running in Standalone or Domain mode.
Host Controller (Applicable for Domain mode): Provide the JBoss Host Controller name.
Server Name: Specify the JBoss server instance name running on the host.
SSL Enabled: Choose whether SSL is enabled for secure communication.
Check Frequency: Choose a polling frequency from the drop-down list.
Location Profile: Select the location profile from where the JBoss Application Server can be monitored from the drop-down list. To learn more, refer to the location profile help page.
Associate with Monitor Group(s): Select a monitor group from the drop-down list to logically group your monitors. To learn how to create a group for your monitors, refer to the monitor groups help page.
In the JBoss User Credentials section, choose the appropriate credentials stored in the Site24x7 Credential Profile or add new ones.
To add a new credential:
Click the + icon next to the JBoss Credential field.
In the resulting Add Credential pop-up, provide a Credential Name to identify the credential. JBoss will be auto-selected as the Credential Type.
Provide the Username and Password of the associated JBoss Application Server account.
Click Save.
Specify the following details for Configuration Profiles, Alert Settings, and Third-Party Integrations:
Tags: Associate your monitor with predefined Tags to organize and manage your monitors creatively. Learn how to add Tags.
ITAutomationTemplates: Select an automation to be executed when WebSphere Application Server's status is down, trouble, or up; when there's any status change; or when there's any attribute change. The defined action gets executed when there is a state change, and the selected user groups get alerted. To automate corrective actions upon a failure, refer to the IT Automation help document.
UserAlertGroup: Select the user group that needs to be alerted during an outage. To add multiple users to a group, see the User Alert Group help document.
NotificationProfile: Choose a notification profile from the drop-down list or select the default profile available. A notification profile helps you configure who gets notified and when in the event of downtime. Refer to the notification profile help document to create a customized notification profile.
Third-Party Integrations: Associate your monitor with preconfigured third-party services. This lets you push your monitor alarms to selected services and facilitate improved incident management.
Click Save.
