seekfiles ignored after server reboot

[nicutor]

Hi,

I gave a reboot to the server and even if the seekfile was there, the logfile was fully processed again.

$protocolsdir = '/usr/local/test/tmp/logfiles';
$seekfilesdir = '/usr/local/test/tmp/logfiles';
$protocolretention = '30';
$scriptpath = '/bin:/usr/bin:/sbin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/usr/local/test/bin';
$options = 'preview=1';

@searches = (
  {
    tag => 'test',
    logfile => '/usr/local/test/logs/test_log',
    criticalpatterns => [
      '\{test\}'
    ],
    options => 'nologfilenocry,nosavethresholdcount,maxlength=1024,allyoucaneat,criticalthreshold=1,script',
    script => 'logfiles_test.sh'
  }
);

Because of this, the script was run again even if was not supposed to do so.

Is this the normal behaviour? I am missing something? Shouldn't the seekfile be used all the time if exists?

Thank you.

You should run it with "-v", then you see some internals, especially how the plugin sees a changed logfile.

Same issue here, the "check_logfiles -v" is attached. Striking is the message

Fri Jan 28 15:47:23 2022: this is not the same logfile /appl/laugh/test.log 64774:4163772 != 64770:4163772

check_logfiles thinks that this is a new file due to the changing device id. Informations about the system: this is a KVM VM, file system is xfs and we're using LVM. The changing device id's are visible in the seek file (parameter "devino"). How can we avoid that then device id's are read and used to recognize the log file? Thanks!

Another remark: the elastic people have similar issues, here the file identity strategy can be configured.

I just made check_logfiles-4.0.1.3.tar.gz

It adds an option ramdomdevno, which ignores the device number and only looks at the inode.

Sorry, I'm to stupid to use that option. What am I doing wrong? ramdomdevno does not work either although the commit c29c3d4 gives the idea that correct option name is randomdevno. Thanks!

I can confirm that version 4.1 (when using the option --randomdevno) solves the issue for me. Many thanks!
