[root@nagios001 ~]#
[root@nagios001 ~]# ./logrobot localhost /tmp/logXrayTesting autonda /var/log/nagios 60m '.' '.'  1 0 MultiLogGrowthChk -ndfoundn

OK: [/var/log/nagios][3]  nagios.debug:P=(=46124)_F=(0)_R=(lnsrd=(46124)=lnct~(1059388)) nagios.log:P=(=41353)_F=(5)_R=(lnsrd=(41353)=lnct~(602640)) servicenow.log:P=(101)_F=(130s)_R=(0,101=101)
