Deploy Monitoring for Apache Tomcat

📡 Deploying GermainUX for Comprehensive Monitoring of Apache Tomcat and Its Components

Deploy the GermainUX components required to monitor Apache Tomcat, its JVM, hosted applications, logs, infrastructure, real-user experience, and critical application workflows.

⚙️ Deployment Architecture

Tomcat monitoring can combine several GermainUX components.

Deploy only the components required for the desired monitoring depth.

📋 Prerequisites

Before deployment, identify:

🧭 Deploy or Select a GermainUX Engine

Use a GermainUX Engine that can reach the Tomcat servers and required supporting services.

The Engine may need connectivity to:

• JMX endpoints

• HTTP/HTTPS endpoints

• Log directories

• Databases

• APIs

• Messaging systems

• Other monitored dependencies

Verify that the Engine can communicate with GermainUX.

🔗 Configure Network Access

Depending on the selected monitoring methods, allow access to the required:

• JMX ports

• HTTP ports

• HTTPS ports

• SSH ports

• Log locations

• Monitoring endpoints

Use only the network access required for the selected monitoring configuration.

⚙️ Deploy JMX Access

Use JMX when Tomcat, connector, session, data-source, and JVM metrics are required.

✅ Verify JMX Availability

Confirm:

• JMX is enabled.

• The JMX endpoint is reachable.

• Authentication is enabled where required.

• TLS or other approved security is configured.

• Firewall rules permit access from the selected GermainUX Engine.

🔒 JMX Security

For production environments:

• Prefer authenticated and encrypted JMX access.

• Restrict access to authorized GermainUX Engines.

• Use a dedicated least-privilege monitoring account.

• Avoid exposing JMX ports to untrusted networks.

• Do not disable authentication or TLS solely for monitoring.

• Store credentials in GermainUX credential configuration.

If remote JMX cannot be secured according to organizational requirements, use another approved collection method.

🔧 Deploy GermainUX Code Profiler — Optional

Deploy GermainUX Code Profiler when Java transaction and code-level analysis is required.

Use it for visibility into:

Before production deployment:

1. Confirm compatibility with the application's Java version.

2. Confirm compatibility with the Tomcat version.

3. Validate the instrumentation in a non-production environment.

4. Follow your organization's change-management process.

📄 Deploy Log Monitoring — Optional

Configure access to the Tomcat and application logs that need to be monitored.

Examples include:

Verify that the selected GermainUX monitoring component has read access to the required files.

Do not collect passwords, authentication tokens, session identifiers, or other sensitive application data unless explicitly required and approved.

🖥️ Deploy Infrastructure Monitoring — Optional

Extend monitoring to the operating system or platform hosting Tomcat.

Depending on the environment, deploy monitoring for:

This enables Tomcat activity to be correlated with:

🌐 Deploy RUM JS — Optional

For browser-based applications hosted by Tomcat, deploy GermainUX RUM JS.

RUM JS enables:

Before production deployment, configure appropriate privacy, masking, exclusions, consent, and retention requirements.

🤖 Deploy Synthetic Monitoring — Optional

Use GermainUX RPA Bot Recorder to create approved synthetic application journeys.

Examples include:

Open Application → Sign In → Execute Critical Workflow → Validate Result

or:

Open Application → Load Critical Page → Validate Content

Use dedicated test accounts and approved test data.

Avoid synthetic actions that unintentionally modify production data.

✅ Validate Deployment

Before configuring production monitoring, verify:

• Engine is online.

• Tomcat servers are reachable.

• JMX is reachable when enabled.

• Authentication succeeds.

• Required HTTP/HTTPS endpoints are reachable.

• Required log directories are accessible.

• Code Profiler is active when deployed.

• RUM JS loads when deployed.

• Synthetic scenarios can execute when configured.

• Supporting infrastructure is reachable when included.

Once the required components are deployed and reachable, continue with Configure Monitoring for Apache Tomcat.
