Hello I have a problem I am using a program logsurfer which scan logfiles and realtime it is running on a remote host, i have created a passive check in nagios and I want to use send_nsca to send the errors in the logs to the monitoring server. whenever i launch send_nsca manually in the command line it works but when I set it in the config file of logsurfer it does not sends any passive checks to the nagios server. here is the command i try to use in order to send it to the nagios server. "/usr/bin/echo "host\tlogfile\t2\t\"$0\"" | /etc/nagios/send_nsca -H 123.123.123.123 -c /etc/nagios/send_nsca.cfg" it is there an error in syntax, does anyone of you know logsurfer and it's maybe the logsurfer problem if the syntax of send_nsca is correct. $0 is supposed to be the entire line that will be sent to the monitoring server. thank you for your help; it will be priceless.
