HOW TO: Increase or decrese dubugging level in Trend Micro Deep Security Virtual Appliance DSVA

The default debug log level in Trend Micro DSVA is 5. To check current debug log level run this command:

grep LOG_EMERG /var/log/syslog

If DSVA was restarted recently and debug level has not been reconfigured since last reboot, you will not get any LOG_EMERG results.  The only way to check current debug log level is to change it up or down and then run grep command again.

To increase or decrease debug logs execute the following commands via ssh or the console:

  • To increase debug logs:
    killall –USR1 ds_am (increments +1, up to level 8)
  • To decrease debug logs:
    killall –USR2 ds_am (decrements -1, down to level 0)

Trend Micro recommends increasing debug level to 6 to allow for more debugging. Reset the debug level to 5 for normal operations.
