ePO uses three server-side services and a Microsoft SQL database, each of which serves a different purpose:
- The Application Server service or Tomcat is responsible for displaying the ePO console GUI.
- The Event Parser service takes events uploaded from clients in the environment and parses them into the SQL database.
- The Server service or Apache processes and receives all agent-server communication in the environment.
IMPORTANT: All three services require and depend on a constant and high-speed connection to the SQL database.
The following are the primary log locations for these services:
- Application Server service (Tomcat): The orion.log or orion_servername.log file is located in:
\<epoinstallationdirectory>\server\logs\
- Event Parser service: The eventparser.log or eventparser_servername.log file is located in:
\<epoinstallationdirectory>\db\logs\
- Server service (Apache): The server.log or server_servername.log file is located in:
\<epoinstallationdirectory>\db\logs\
