im_file ; File with lock | Log collection solutions

#1 karrakis 8 years ago

Hello,

Recently, i ran into a problem with file locking. One application here is generating some log file, one per client, when nxlog try to read file, i got error :

ERROR failed to open LOGFILEPATH; Le processus ne peut pas accéder au fichier car ce fichier est utilisé par un autre processus.

Initaly my configuration was :

<Input Orbis>
   Module im_file
   File 'LogDirectory\\*'
   SavePos TRUE
   ReadFromLast FALSE
   CloseWhenIdle TRUE
   InputType orbisLog
Exec if $raw_event !~ /^L:.*/ drop();
   Exec $ClientNAme = replace(file_basename(file_name()),'.LOG','');

</Input>

I have changed the PollIntervall to 60 and 3600, no effect... Except that at PollInterval 3600, nxlog grab 40% of CPU.

Is there a way to insctruct nxlog to retry to read the file ?

If pollinterval 3600 results in a high CPU utilization then there is obviously something wrong.

Other than that NXLog should retry the file later after encountering an error.
