    - Configuring the Discover Data Service
      The Discover Data Service manages connections between Discover components and services and the databases they are querying. This service allows database connectivity to be managed as a Windows™-based service for security, reliability, and control.
      - Connections
        The Discover Data Service replaces some of the functionality managed by the Search Server, which utilizes SQL authentication for direct access to the Discover databases. In some environments, this authentication method is problematic.
      - Installation
        During the installation process, the Discover Data Service is installed on the same server where the Discover Data Collector is installed. The Discover Data Service uses the same registry settings to self-configure and connect to the Discover databases.
      - Configuring Discover Data Service
        Through Search Server, Discover servers and services communicate with the Data Service and the Report Server by extension.
      - Starting and Stopping the Service
        You can start, stop, and restart the Discover Data Service through Manage Services.
      - Logging
        This section describes how to manage and use the Data Service log files through HCL Discover Portal.
        Accessing Logs
        Discover administrators may access the Data Service log files through the Discover Portal.
        Log File Location
        Discover Data Service generates log messages in the following log file:
        Changing the Log Level
        By default, the log level for the Discover Data Service is set to 1, which means that the log file contains only the following types of status messages:
        Per-Minute Data Service Stats
        In addition to core logging functions, the Data Service writes statistical information on its current state to .CSV files in the Logs directory. These files provide performance information on the Data Service CPU usage, threads, handles, requests, and more.
    - Databases
      This section provides some overview information on each of the HCL Discover databases.
    - Database backup strategy
      Your Discover databases should be backed up regularly for recovery and performance reasons. Without valid backups, Discover may be unable to recover customer data in the event of a system failure or data corruption.
    - Troubleshooting Discover databases
      If you are experiencing an access or performance-related issue with your installed Discover SQL database, review the troubleshooting tips in this section, which may help to resolve your issue.
  - Report Access Permissions
    Users whose accounts contain the proper permissions may administer Discover reports. Depending on the type of report, permissions to administer individual reports of that type are configured in the report definition.
  - Managing User Agents
    Through Discover, you can monitor the different types of user agents that contact your web application. Through a provided set of data objects, Discover can identify the type of traffic that is requesting resources from your web application and then monitor counts and other information that pertains to the type of user agent. These objects can be used as the source data for developing a useful set of user agent-related reports, enabling you to closely monitor the composition of traffic to your site.
  - Configuring User Agent Detection
    This section describes how to acquire and maintain the configuration files necessary for parsing of fixed and mobile user agents and how to prepare those files for use in the HCL Discover platform.
  - Configuring User Agent Events
    To use the data that is injected into the [ExtendedUserAgent] section by the Discover SessionAgentTLTRef, a Discover administrator must create events that create charts for this data.
  - User Agent Tools
    These external utilities can be used to monitor and update user agent configuration data that is required by Discover.
  - bot Detection
    Most commercial enterprise web applications are subjected to significant traffic from web crawling bots. Short for "robot," a bot is a software agent that navigates websites to extract information about them. Some bots are used by search engines for indexing pages.
  - Discover Reference Information
    Use the links below to access reference information on file formats, common standards, and more in use by the Discover system.
  - Integrating HCL Discover and Unica Journey
    HCL Discover and Unica Journey integration works with CEP configuration. The CEP configuration enables the event to be sent to CEP and the external systems. Unica Discover-Unica Journey integration is supported from version 12.1.0.3 onwards.
  - Integrating HCL Discover and Unica Interact
    HCL Discover and Unica Interact integration works with CEP configuration. The CEP configuration enables the event to be sent to CEP and the external systems. Unica Discover-Unica Interact integration is supported from version 12.1.0.3 onwards.
  - Selective Deletion
    You can delete sessions and session fragments from the HCL Discover system with the Selective Deletion tool.
  - Using the ArchiveConfig utility
    Run the ArchiveConfig utility to configure and execute Selective Archiving.
  - ELK Configurations
    Before configuring ELK on HCL Discover, there are some prerequisites:
  - Securing Interprocess Communication
    Discover 12.1.8 and above supports the use of a new SSL certificate based mechanism for securing all inter-process communication between the Discover servers. This is important in a distributed environment with multiple servers, as the components of Discover communicate with each other over the network, using a variety of ports.

Changing the log level

By default, the log level for the Discover Data Service is set to 1, which means that the log file contains only the following types of status messages:

Startup
Shut-down
Verification of connection to all databases

If needed to resolve specific issues with the Discover Data Service, you can change the logging level to a value between 1 and 9. If Log Level 9 is enabled via Manage Services, the Data Service log file contains individual request information and additional trace/debug statements to assist in resolving issues.

The Discover Data Service shares the same logging controls as other services managed through the Report Server. To change the logging level for it and other Report Server functions, set the Log Level value on the Database tab in the Report Server configuration in Manage Services.

See "Configuring the Report Server" in the HCL Discover Configuration Manual.
