Download the CDT available in the Trend Micro Download Center.
Starting from October 2019, there is a second version of Case Diagnostic Tool (CDT) 2019 (Apex One Exclusive) available for log collection purposes. If you are using OfficeScan version 11.0, XG, Apex One or Apex One Central, CDT 2019 (Apex One Exclusive) is recommended as it is lite weight and faster than the traditional CDT.
CDT 2019 (Apex One Exclusive) also allows log collection without restarting product related services and processes.
The following will be collected when running CDT:
- Registry information related to the OfficeScan/Apex One client and server
- Running services
- Task list
- List of registered programs installed
- System info
- OfficeScan/Apex One client and server configuration files
- Client and server log files
- Install log
- Patch log
- Web Server logs (Server)
- Operating system Application and System Event logs
