Apache Tomcat
Overview
Apache Tomcat, the widely used open-source application server, seamlessly integrates with Motadata AIOps to provide comprehensive monitoring capabilities. With this integration, organizations gain real-time visibility into the performance and health of their Apache Tomcat servers. Monitor critical server metrics such as request rates, response times, and JVM (Java Virtual Machine) statistics to ensure optimal application performance.

Prerequisites for Apache Tomcat Integration with Motadata AIOps
Ensure that the Apache Tomcat port (default: 8067) is open for the Motadata AIOps server.
Provide the necessary credentials, including the username and password, for Motadata AIOps to connect to the Apache Tomcat server.
Confirm that the Apache Tomcat service is active and running on the server.
Confirm that the Apache Tomcat process and service are listed in the process and monitor settings of Motadata AIOps. Although these may be listed by default, ensure that the names of the service and process match the specific Apache Tomcat version that you intend to monitor.
In the address area of your browser, type http://[IP]:8080/manager/status, submit the address, provide the credentials, and click on the Server Status link to confirm the status of the Apache Tomcat server.
where [IP] is the IP address of the server where Apache Tomcat is installed
Confirm that the Apache Tomcat server supports either HTTP or HTTPS protocol.
In the tomcat-users.xml file, add the following text:
<tomcat-users>
<role rolename="manager-gui"/>
<role rolename="manager-jmx"/>
<user username="[username]" password="[password]" roles="manager-gui, manager-jmx"/>
</tomcat-users>Here, Replace [username] and [password] with the credentials used to access the Apache Tomcat server. These credentials will be configured in Motadata AIOps to enable access to the Tomcat server.
For agentless monitoring, ensure that the user has the required access for remote access to the Apache Tomcat server. For agent-based monitoring, this is not required.
By following these prerequisites, you can integrate Apache Tomcat with Motadata AIOps and ensure the smooth functioning of the monitoring process.
