Hi Gerd

I'm struggling with the "undocumented" interface-file feature.  I have the same 
gaps problem.  I've implemented your suggestions, but I'm confused about how 
the data get's converted into rrd's.

with the pipe's version my command.cfg contained
define command{
      command_name    process-service-perfdata
      command_line    /usr/lib64/nagios/plugins/contrib/fifo_write.pl  
/var/log/nagios/rw/ngraph.pipe '$HOSTNAME$      $SERVICEDESC$   $SERVICEOUTPUT$ 
$SERVICEPERFDATA$' 3
      }
This passed the data into the pipe where the collect2.pl was watching and 
converted the data in rrd's

with the file version, I removed that definition and replaced it with:

define command{
       command_name process-service-perfdata-file
       command_line mv /usr/local/nagios/var/service-perfdata 
/usr/local/nagios/var/service-perfdata.$TIMET$
       }

Now Nagios sends the data to service-prefdata, which is mv'd to a timestamped 
file periodically.

How is the data supposed to get converted into rrd's now?  How does the 
collect2.pl daemon know when to process the files?  As it is now, no rrd files 
are generated.  collect2.pl is running, nagios is sending the data to 
/dev/shm/service-perfdata and then they are moved to 
/dev/shm/service-perfdata.<stamp>.  

my fifo version worked, it just had gaps.


thanks for your help
