Hi, I am doing a test with the agent nxlog EE v.5.3.6735_windows_x64 and after the installation of the agent on the server I stopped receiving the windows audit logs (im_msvistalog module) that I was receiving regularly with the version of nxlog CE v.2.10.2150 and I am not getting the IIS logs either.
I attach the implemented configuration file:

Panic Soft

define INSTALLDIR C:\Program Files\nxlog

#ModuleDir %INSTALLDIR%\modules
#CacheDir %INSTALLDIR%\data
#SpoolDir %INSTALLDIR%\data

define CONFDIR %INSTALLDIR%\conf\nxlog.d

# Note that these two lines define constants only; the log file location
# is ultimately set by the `LogFile` directive (see below). The
# `MYLOGFILE` define is also used to rotate the log file automatically
# (see the `_fileop` block).
define MYLOGFILE %LOGDIR%\nxlog.log

# If you are not using NXLog Manager, disable the `include` line
# and enable LogLevel and LogFile.
#include %CONFDIR%\*.conf

LogLevel INFO

# This block rotates `%MYLOGFILE%` on a schedule. Note that if `LogFile`
# is changed in managed.conf via NXLog Manager, rotation of the new
# file should also be configured there.
<Extension _fileop>
Module xm_fileop

# Check the size of our log file hourly, rotate if larger than 5MB
Every 1 hour
if ( file_exists('%MYLOGFILE%') and
(file_size('%MYLOGFILE%') >= 5M) )
file_cycle('%MYLOGFILE%', 8);

# Rotate our log file every week on Sunday at midnight
When @weekly
Exec if file_exists('%MYLOGFILE%') file_cycle('%MYLOGFILE%', 8);
