Download: pnp4nagios-0.6.24.tar.gz Document Section Http://docs.pnp4nagios.org/pnp-0.6/start

PnP is a Nagios plug-in that can analyze data and store them automatically rrd-databases

RRDtool is an open source industry standard that provides high-performance data recording time series data and graphic rendering systems

Download Link: Http://oss.oetiker.ch/rrdtool/pub/?M=D

Use rrdtool-1.2.12.tar.gz here

[Email protected] rrdtool-1.2.12]#./configure

[[email protected] rrdtool-1.2.12]# make all &&make install

[[email protected] pnp4nagios-0.6.24]# ls/usr/local/rrdtool-1.2.12/installed directory

BULK Mode with NPCD

The default is to run synchronous mode and compare wasted resources it is the execution of every event that will trigger Process-service-perfdata

So using the bulk mode batch mode here is more complex than synchronous mode but can significantly reduce the load on the Nagios server because the Data collector process_perfdata.pl not invoke each service/host check.

In batch mode, Nagios writes data to a temporary file. This file is handled by Process_perfdata. At a specific interval. Nagios will regularly take care of starting and running it

• First enable the receipt collection switch in Nagios.cfg

Process_performance_data=1

#
# Service performance data
#
Service_perfdata_file=/usr/local/pnp4nagios/var/service-perfdata
Service_perfdata_file_template=datatype::serviceperfdata\ttimet:: $TIMET $\thostname:: $HOSTNAME $\tservicedesc::$ Servicedesc$\tserviceperfdata:: $SERVICEPERFDATA $\tservicecheckcommand:: $SERVICECHECKCOMMAND $\thoststate::$ Hoststate$\thoststatetype:: $HOSTSTATETYPE $\tservicestate:: $SERVICESTATE $\tservicestatetype:: $SERVICESTATETYPE $
Service_perfdata_file_mode=a
Service_perfdata_file_processing_interval=15
Service_perfdata_file_processing_command=process-service-perfdata-file

#
# Host performance data starting with Nagios 3.0

Host_perfdata_file_mode=a
Host_perfdata_file_processing_interval=15
Host_perfdata_file_processing_command=process-host-perfdata-file

• Edit Command.cfg

  Define Command{
  Command_name Process-service-perfdata-file
  command_line/usr/local/pnp4nagios/libexec/process_perfdata.pl--bulk=/usr/local/pnp4nagios/var/service-perfdata
  }
  
  Define Command{
  Command_name Process-host-perfdata-file
  command_line/usr/local/pnp4nagios/libexec/process_perfdata.pl--bulk=/usr/local/pnp4nagios/var/host-perfdata
  }
