Gerd,
After making below changes as you suggested, I did a "pre-flight"
# nagios -v /etc/nagios/nagios.cfg
Nagios 2.9

Things look okay - No serious problems were detected during the pre-flight

And then a restart of Nagios and Nagiosgrapher, were Nagiosgrapher failed,
[root at laknagios /]# /etc/init.d/nagios restart

Do you have any advice?

Hi,
the old NagiosGrapher interfaces (network/pipe) can cause huge
latency :-(. Thanks to a patch we got there is a new interface type
"file". The main advantages of this new interface are:
* no gaps any more
* no latency caused by NagiosGrapher
* restarting NagiosGrapher does not cause any gaps
I am sorry but the documentation totally lacks this interface. But below
is all you need.
Cheers,
Gerd
ngraph.ncfg:
interface file
perffile_path /dev/shm
nagios.cfg:
process_performance_data=1
service_perfdata_file=/dev//shm/service-perfdata
service_perfdata_file_template=$HOSTNAME$\t$SERVICEDESC$\t
$SERVICEOUTPUT$\t$SERVICEPERFDATA$\t$TIMET$
service_perfdata_file_mode=a
service_perfdata_file_processing_interval=60
service_perfdata_file_processing_command=process-service-perfdata-file
commands.cfg:
define command{
command_name process-service-perfdata-file
command_line
mv /dev/shm/service-perfdata /dev/shm/service-perfdata.$TIMET$
}
