change rotate file name with file_cycle | Log collection solutions

#1 Savane 7 years ago

Hello :),

I make a file rotation when my logs size exceed with 'file_cycle'.

I have something like this :

   Exec   if outUDP->file_size() > 10k  \
           { \
               log_info('size exceeded');  \
               file_cycle(%LOGDIR% + $programSource + '\\' + get_var('date') + '.log'); \
               outUDP->reopen(); \
           }

So my logs paths are :

C:\logs\programA\20170329.log
C:\logs\programA\20170329.log.1
C:\logs\programA\20170329.log.2
C:\logs\programB\20170329.log.1
C:\logs\programB\20170329.log.2

But I wanted something more like :

C:\logs\programA\20170329.log
C:\logs\programA\20170329.1.log
C:\logs\programA\20170329.2.log
C:\logs\programB\20170329.1.log
C:\logs\programB\20170329.2.log

I wanted to make it by myself using 'rotate_to' instead of 'file_cycle' .
The probleme is if nxlog restarts, I need it to continue the file rotation without overwrite the files that already exist. I can't check if C:\logs\programA\20170329.1.log exists then C:\logs\programA\20170329.2.log until I find the last...

It is possible to change it using 'file_cycle'? Or do you have another idea?

Thanks :)

Why don't you just write to a file with the timestamp in the filename directly?

<Output out>
    Module  om_file
    File    %LOGDIR% + $programSource + "_" + strftime(now(), "%Y%m%d%H%M%S");
