I am using the below configuration file in order to generate the alert for the mentioned pattern but it is not giving the alert as mentioned threshold count.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++===

Code: Select all

[ericsson@euc-3-3-uc-00-0 conf]$ cat Error_code_404.conf
$seekfilesdir = '/home/ericsson/logfile_basedir/tmp';
$protocolsdir = '/home/ericsson/logfile_basedir/tmp';
$scriptpath = '/home/ericsson/bin';
#$MACROS = { CL_DISK01 => "/dev/dsk/c0d1", CL_DISK02 => "/dev/dsk/c0d2" };
@searches = (
        {
                tag => 'Error_code_404',
                criticalpatterns => ['HTTP/1.1" 404'] ,
                logfile =>'/opt/universalcache/logs/access.log',
                #options => 'sticky=1800,noprotocol,report=long,allyoucaneat',
                rotation => 'REDHAT',
                #warningthreshold => 100,
                criticalthreshold => 3500
        }
);

check interval 3 minutes

Code: Select all

-C "sudo /home/ericsson/bin/check_logfiles -f /home/ericsson/logfile_basedir/conf/Error_code_404.conf"
-t 60 -o StrictHostKeyChecking=no -l ericsson -E

It looks like you just need to escape the quotes in the pattern. Try:

criticalpatterns => ['HTTP/1.1\" 404'] ,

After changing the pattern as well i am getting alert at very less count can you suggest how can i fix this as it is pending from long time

Below is how i have done the analysis for the check.
Alerts which are mentioned in state history i have observed that check interval is 3 min but time large time difference between OK pattern and alert generated if i am calculating the count in between the OK pattern and alert that only it is crossing the threshold defined

Is this service pending from this plugin correct? Was it like this before, or did it happen after you made changing the pattern?

Could you give us a screenshot just to be sure?
