How to Discover Apache Tomcat

This task describes how to discover the Apache Tomcat application and includes the following steps:

1. Prerequisite - Set up network and protocol credentials

   This discovery uses the following protocols:

   • NTCMD Protocol

   • SSH Protocol

   • Telnet Protocol

   For credential information, see Supported Protocols.

2. Run the Discovery

   1. Run the Range IPs by ICMP job to discover IPs in the range where Tomcat is running.

   2. Run the Host Connection by Shell job to discover Shell agents.

   3. Run the Host Applications by Shell job to verify that an Apache Tomcat is running on the system, and to discover Tomcat-specific processes. If these processes are discovered, the job creates Tomcat CIs.

   The job searches for the java.exe (or java) process name, then searches in the command line for either the -Dcatalina.home= or -Dcatalina.base= substring. This substring includes the path to the Tomcat home directory. If this substring is not found, the job searches for a process name starting with tomcat and, from there, acquires the path to the home directory.

   The job then finds the absolute path to the Tomcat configuration file and adds this path as an attribute (webserver_configfile) to the Tomcat CI.

   4. Run the Apache Tomcat by Shell job. This job uses the Tomcat CI attribute to locate the configuration files that are discovered by the Host Applications by Shell job.

   For details on running jobs, refer to "Module/Job-Based Discovery" in the Data Flow Management section of the UCMDB Help.
