And sometimes one is using too many complicated tools when an easier
answer it to use tools at hand.

I have redefined nagios to use printf and it seems to work. If anyone want
to try it:

# 'process-service-perfdata' command definition
define command {
        command_name    process-service-perfdata
#       command_line    /usr/lib/nagios/eventhandlers/fifo_write.pl     /var/lib/nagios/ngraph.pipe     '$HOSTNAME$     $SERVICEDESC$   $SERVICEOUTPUT$ $SERVICEPERFDATA$'      3
#       command_line    /usr/lib/nagios/nagiosgrapher/fifo_write.pl /var/spool/nagios/ngraph.pipe '$HOSTNAME$\t$SERVICEDESC$\t$SERVICEOUTPUT$\t$SERVICEPERFDATA$\n' 3
#       command_line    /usr/lib/nagios/nagiosgrapher/fifo_write        /var/spool/nagios/ngraph.pipe '$HOSTNAME$\t$SERVICEDESC$\t$SERVICEOUTPUT$\t$SERVICEPERFDATA$'   3
        command_line    /usr/bin/printf "%b" "$HOSTNAME$\t$SERVICEDESC$\t$SERVICEOUTPUT$\t$SERVICEPERFDATA$\n" >> /var/spool/nagios/ngraph.pipe
#       command_line    /usr/lib/nagios/nagiosgrapher/write_fifo -p /var/spool/nagios/ngraph.pipe -s '$HOSTNAME$        $SERVICEDESC$   $SERVICEOUTPUT$ $SERVICEPERFDATA$'
#       command_line    /usr/bin/printf "%b" "$LASTSERVICECHECK$\t$HOSTNAME$\t$SERVICEDESC$\t$SERVICESTATE$\t$SERVICEATTEMPT$\t$SERVICESTATETYPE$\t$SERVICEEXECUTIONTIME$\t$SERVICELATENCY$\t$SERVICEOUTPUT$\t$SERVICEPERFDATA$\n" >> /var/log/nagios/service-perfdata.log
        }

As one can see I have tried quite a few options.

I will let it run tonight while I sleep. I will give you an update in the
morning. (Fingers crossed ;-)

Hugo.
