Dear Community

i have a output module in a file. Which creates a folder named with incomer IP Address. In this folder will be a file named Syslog+time+.log. This file is created every hour new. Thats works very good. Every new syslog sender is creating a new filder with its own IP address

Abstarct C:\Program Files (x86)\nxlog\data\\Syslog-.log Reality C:\Program Files (x86)\nxlog\data\123.123.123.123\Syslog-2018-23-01.log C:\Program Files (x86)\nxlog\data\123.123.123.123\Syslog-2018-23-02.log and so on a another folder C:\Program Files (x86)\nxlog\data\124.124.124.124\Syslog-2018-23-01.log

Code: Module om_file File $MessageSourceAddress+"/Syslog-"+ strftime(now(),"%Y-%m-%d-%H") + ".log" CreateDir TRUE

up to this stage everything works. Now I want create a deletion process of the files which are older than a particular time.

I try to use file_remove function but it is not working for me.

I try to get the IP folder name with $MessageSourceAddress. Therefore i create a variable (test). This variable should carry the foldername (123.123.123.123). with Exec {if not defined get_var('test') {create_var('test');} set_var('test',$MessageSourceAddress);}

Now I try to request the variable back in the file_remove function: Exec file_remove('C:\Program Files (x86)\nxlog\data\+ 'get_var('test')'\*.log', (now()));

I always get this error

2018-01-23 14:20:20 WARNING stopping nxlog service 2018-01-23 14:20:20 WARNING nxlog received a termination request signal, exiting... 2018-01-23 14:20:22 ERROR Couldn't parse Exec block at C:\Program Files (x86)\nxlog\conf\nxlog.conf:96; couldn't parse statement at line 96, character 72 in C:\Program Files (x86)\nxlog\conf\nxlog.conf; syntax error, unexpected TOKEN_FUNCPROC, expecting ) 2018-01-23 14:20:22 ERROR module 'file2' has configuration errors, not adding to route '1' at C:\Program Files (x86)\nxlog\conf\nxlog.conf:130 2018-01-23 14:20:22 WARNING not starting unused module eventlog

whole output module

Module om_file File $MessageSourceAddress+"/Syslog-"+ strftime(now(),"%Y-%m-%d-%H") + ".log" CreateDir TRUE ##Variable create Exec {if not defined get_var('test') {create_var('test');} set_var('test',$MessageSourceAddress);} ## deltet old files Exec file_remove('C:\Program Files (x86)\nxlog\data\+ 'get_var('test')'\*.log', (now())); Exec to_syslog_ietf();

I think the error is caused by the following:

 Exec file_remove('C:\Program Files (x86)\nxlog\data\+ 'get_var('test')'\*.log', (now())); Exec to_syslog_ietf(); 

You need to use + for the string concatenation: get_var('test') + '\*.log'

    Dear Botond, thx for the advise the solution for our problem is code line = ****Exec file_remove('C:\Program Files (x86)\nxlog\data\' + get_var('test') + '\Sys*.log');
