To enable performance logging:

1. On the VM with the DSA, disable agent protection by running the following command:

   For Deep Security 9.0:

   c:\program files\trend micro\deep security agent\dsa_control.exe --harden=0

   For Deep Security 9.5:

   c:\program files\trend micro\deep security agent\dsa_control –s=0

   Where the value of "s" is:
   s = 1 - to enable self-protection (default)
   s = 0 - to disable self-protection

   This will allow you to stop the Agent services.

2. Stop the Anti-Malware Solution Platform (AMSP) service using this command:

   net stop amsp

3. Create a backup copy of the C:\Program Files\Trend Micro\AMSP\AmspConfig.ini file.
4. Edit the AmspConfig.ini file by setting these values:

   DebugLevel=1
   DebugFlag=7

5. Start the AMSP service using this command:

   net start amsp

6. Run the C:\Program Files\Trend Micro\AMSP\AMSP_LogServer.exe file.
7. Replicate the issue.
8. Stop AMSP_LogServer.exe by pressing CTRL+C.
9. Go to C:\Program Files\Trend Micro\AMSP\debug.
10. Collect the files Amsp_DebugLog and Amsp_Event, and send them to Trend Micro Technical Support. Indicate the time of testing.
11. Repeat Steps 1 and 2 to stop the AMSP service again.
12. Restore C:\Program Files\Trend Micro\AMSP\AmspConfig.ini file to its original values.
13. Start the AMSP service using this command:

    net start amsp
