To increase or decrease debug level of the anti-malware process:

1. Open a command prompt via SSH or through the console.
2. Run the following commands to increase or decrease the debug level:
   • To increase debug level:

     sudo killall –USR1 ds_am (increments +1, up to level 8)

   • To decrease debug level:

     sudo killall –USR2 ds_am (decrements -1, down to level 0)

3. Open /var/log/syslog for the results.
4. Reset the debug level to 5 for normal operations.

   sudo killall –USR1 ds_am (+1, up to level 8)
   sudo killall –USR2 ds_am (-1, down to level 0)

    

   For Deep Security 9.5 and above, the AM log is changed from /var/log/messages to /var/opt/ds_agent/diag/ds_am.log. You can use the signals to increase and decrease debug level.

To verify the debug level:

1. Open a command prompt via SSH or through the console.
2. Run the following command:

   tail –f /var/opt/ds_agent/diag/ds_am.log | grep debug_level

   The results, similar to the image below, will show the current debug level:

   

    

   For Deep Security 9.0, it is unnecessary to verify using this way, as the change in the debug level information will automatically appear upon typing the debug command.
