program.sh is working for me.
Anything else doesn't, no errors. I have tried this exhaustively. I think I'll just give up cause its driving me nuts.

The actual scripts I wrote are much longer. It didn't work for them, and when I narrowed it down this was the main problem.

Okay, so my fault here I over simplified my example in OP.

This is more of what I'm doing which for the line previous to the send_nsca binary program is not working:

in shell:

Code:
echo "host,log,0,message" | program_below.sh

program:

Code:
while read -r line; do
  STRING=$line
        echo $STRING > /usr/local/nagios/syslog/debug #and I see no output in debug file
        echo $STRING | /usr/local/nagios/libexec/send_nsca -H 192.168.93.55 -d ',' -c /usr/local/nagios/etc/send_nsca.cfg #this works
done

HELP!!! LOL Smilie

These are all working, my bad, but for some reason they didn't before.

Solved the problem.

I am using syslog-ng program() as a destination for a log.

Apparently, the problem has to do with the absolute path in the script. I'm guessing if calling with program() it leaves the directory that script is called from, so the absolute path is necessary. Either way, it works now to:
absolute_path/debug.log

Thanks for the response, hours upon hours again wasted for nothing, I will ALWAYS freaken add an absolute path to every line of every script from now on. Lesson learned.

syslog.conf(4)						     Kernel Interfaces Manual						    syslog.conf(4)

NAME
syslog.conf - syslogd configuration file SYNOPSIS
facility.severity destination Where: Is part of the system generating the message, specified in /usr/include/sys/syslog_pri.h. See also the syslogd(8) reference page. The severity level, which can be emerg, alert, crit, err, warning, notice, info, or debug. See /usr/include/sys/syslog_pri.h. The syslogd daemon logs all messages of the specified severity level plus all messages of greater severity. For example, if you specify level err, all messages of levels err, crit, alert, and emerg or panic are logged. A local file pathname to a log file, a host name for remote logging or a list of users. In the latter case the users will receive messages when they are logged in. An asterisk (*) causes a message to be sent to all users who are currently logged in. DESCRIPTION
The /etc/syslog.conf file is a system file that enables you to configure or filter events that are to be logged by syslogd. You can specify more than one facility and its severity level by separating them with semicolons. You can specify more than one facility logs to the same file by separating the facilities with commas, as shown in the EXAMPLES section. The syslogd daemon ignores blank lines and lines that begin with an octothorpe (#). You can specify # as the first character in a line to include comments in the file or to disable an entry. The facility and severity level are separated from the destination by one or more tab characters. If you want the syslogd daemon to use a configuration file other than the default, you must specify the file name with the following com- mand: # syslogd -f config_file Daily Log Files You can specify in the /etc/syslog.conf file that the syslogd daemon create daily log files. To create daily log files, use the following syntax to specify the path name of the message destination: /var/adm/syslog.dated/ { file} The file variable specifies the name of the log file, for example, mail.log or kern.log. If you specify a /var/adm/syslog.dated/file path name destination, each day the syslogd daemon creates a sub-directory under the /var/adm/syslog.dated directory and a log file in the sub-directory, using the following syntax: /var/adm/syslog.dated/ date / file Where: The date variable specifies the day, month, and time that the log file was created. The file variable specifies the name of the log file you previously specified in the /etc/syslog.conf file. The syslogd daemon automatically cre- ates a new date directory every 24 hours and also when you boot the system. The current directory is a link to the latest date directory. To get the latest logs, you only need to reference the /var/adm/syslog.dated/current directory. EXAMPLES
The following is a sample /etc/syslog.conf file: # # syslogd config file # # facilities: kern user mail daemon auth syslog lpr binary # priorities: emerg alert crit err warning notice info debug # kern.debug /var/adm/syslog.dated/kern.log user.debug /var/adm/sys- log.dated/user.log daemon.debug /var/adm/syslog.dated/daemon.log auth.crit;syslog.debug /var/adm/syslog.dated/syslog.log mail,lpr.debug /var/adm/syslog.dated/misc.log msgbuf.err /var/adm/crash.dated/msgbuf.savecore kern.debug /var/adm/messages kern.debug /dev/console *.emerg * FILES
/etc/syslog.conf /etc/syslog.auth - Authorization file for remote logging. /usr/include/sys/syslog_pri.h - Common components of a syslog event log record. RELATED INFORMATION
Commands: /usr/sbin/syslogd(8), /usr/sbin/binlogd(8) System Administration delim off syslog.conf(4)
