Hi, I'm currently outputting my desired log into a specific folder. I'm attempting to rotate the output file by size. Is there any limitations if i'm not under a enterprise license? Anyway this is the error i'm getting: ERROR failed to determine file size of 'APPLOGFILE': The system cannot find the file specified. This is my config Panic Soft #NoFreeOnExit TRUE define ROOT C:\Program Files (x86)\nxlog define CERTDIR %ROOT%\cert define CONFDIR %ROOT%\conf define LOGDIR %ROOT%\data define LOGFILE %LOGDIR%\nxlog.log LogFile %LOGFILE% Moduledir %ROOT%\modules CacheDir %ROOT%\data Pidfile %ROOT%\data\nxlog.pid SpoolDir %ROOT%\data define APPLOGFILE'/Program Files/Nxlog/Parsed_syslog/my_parsed.log' Module xm_fileop Module xm_exec Module xm_syslog Module xm_charconv AutodetectCharsets utf-8, euc-jp, utf-16, utf-32, iso8859-2 Module xm_json Module xm_multiline HeaderLine /[\d\t .:]+ [1A-Za-z-]+ [MXZa-z-]+ [\d.\/-]+ [\d:]+ CEST \|/ #5140 udp listenner Module im_udp Host 0.0.0.0 Port 5140 #writes input to a file Module om_file File '/Nxlog/Raw_syslog/'+ strftime(now(),'_%Y_%m_%d') + '_my_raw.log' Module im_file SavePos True ReadFromLast True File '/Nxlog/Raw_syslog/'+ strftime(now(),'_%Y_%m_%d') + '_my_raw.log' InputType multiline_header $type = 'my Log'; $SourceModuleName = 'NxLog'; $SourceModuleType = 'my Log Source'; $Message = $raw_event; if not (($raw_event =~ /TEST REGEX/)) drop(); Module pm_norepeat CheckFields Hostname, Message, SourceName #output of the transformation Module om_file File 'D:/Program Files/Nxlog/Parsed_syslog/my_parsed.log' Exec $raw_event = to_json(); Every 30 sec if(file_size('APPLOGFILE') >= 100M) { file_cycle('APPLOGFILE',500); my_json_out->reopen(); } #1st route Path udp_my_listenner => my_raw_to_file #2nd route Path raw_udp_file => norepeat => my_json_out * What am i doing wrong? can anyone suggest a better config? This is my first time configuring log rotation via nxlog. * What i would like to achieve as and output is that every x seconds if the file exceeds 100MB it's rotated and a new file is created.
