Load Pnp4nagios function for Nagios

Nagios installation is no longer redundant, install Pnp4nagios software directly on the Nagios server

Install the Display graphics page Pnpnagios (RRDtool tool for storing data and drawing, Pnpnagios to display graphical data)

Reference: Http://docs.pnp4nagios.org/pnp-0.6/install

http://docs.pnp4nagios.org/pnp-0.6

Tar XF pnp4nagios-0.6.25.tar.gz

CD pnp4nagios-0.6.25

Yum Install RRDtool rrdtool-perl-y

./configure

Compile error:

Checking for Perl Module time::hires ... no

Configure:error:Perl Module time::hires Not available

Workaround:

Yum-y Install Perl-time-hires

Compile again

./configure

Make all

Make install

Make install-webconf

Make Install-config

Make Install-init

Make Fullinstall

After installation, the following output appears:

Review the options above for accuracy. If They look okay,

Type ' make all ' to compile.

Because Nagios uses the 4.1.1,pnp4nagios to use the 0.6.25

In the official document there are several types of configuration Pnp4nagios mode, but the use of sync mode will not collect data, and error, and then switch to bulk mode with NPCD, a successful plot, here analysis of the configuration process:

Reference: http://www.aboutmonitoring.com/installing-nagios-core-4-pnp4nagios-check_mk-nagvis-centos-7-redhat-7/

1, edit the nagios.cfg file, modify

Process_performance_data=0 change this value to 1

##### values:1 = Process performance data, 0 = Do not process performance data

Enable_environment_macros=1

2. Then remove the following two comments to enable it:

#host_perfdata_command =process-host-perfdata

#service_perfdata_command =process-service-perfdata

Then add the following in the Nagios.cfg configuration file:

# 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=/usr/local/pnp4nagios/var/host-perfdata

Host_perfdata_file_template=datatype::hostperfdata\ttimet:: $TIMET $\thostname:: $HOSTNAME $\thostperfdata::$ Hostperfdata$\thostcheckcommand:: $HOSTCHECKCOMMAND $\thoststate:: $HOSTSTATE $\thoststatetype:: $HOSTSTATETYPE $

Host_perfdata_file_mode=a

Host_perfdata_file_processing_interval=15

Host_perfdata_file_processing_command=process-host-perfdata-file

The use of individual files can be viewed in the official instructions

3, modify the Commands.cfg

Define Command{

Command_name Process-service-perfdata-file

Command_line/bin/mv/usr/local/pnp4nagios/var/service-perfdata/usr/local/pnp4nagios/var/spool/service-perfdata. $TIMET $

}

Define Command{

Command_name Process-host-perfdata-file

Command_line/bin/mv/usr/local/pnp4nagios/var/host-perfdata/usr/local/pnp4nagios/var/spool/host-perfdata. $TIMET $

}

Then turn on the NPCD service:

/usr/local/pnp4nagios/bin/npcd-d-f/usr/local/pnp4nagios/etc/npcd.cfg

4.

[Email protected] libexec]#/etc/init.d/nagios checkconfig

Running Configuration Check ...

Ok.

[Email protected] libexec]# service httpd restart

Stop httpd: [OK]

Starting httpd:

[Email protected] libexec]#/etc/init.d/nagios Reload

Running Configuration Check ...

Reloading Nagios configuration ...

Done

5. Browser access

http://192.168.1.155/pnp4nagios/

Error occurred: PHP gd extensionPHP gd extension not available

Solve:

Yum-y Install PHP-GD

[Email protected] libexec]#/etc/init.d/nagios checkconfig

Running Configuration Check ...

Ok.

[Email protected] libexec]# service httpd restart

Stop httpd: [OK]

Starting httpd:

[Email protected] libexec]#/etc/init.d/nagios Reload

Running Configuration Check ...

Reloading Nagios configuration ...

Done

Then watch the browser error:

Your environment passed all requirements. Remove or rename the/usr/local/pnp4nagios/share/install.php file now.

Workaround:

Mv/usr/local/pnp4nagios/share/install.php/usr/local/pnp4nagios/share/install.php.ignore

The above only solves the function of collecting data, and must show the corresponding graphics on each host and service.

Settings are as follows:

Edit the templates.cfg template file to create the host and service support Pnp4nagios features:

Define host {

Name Host-pnp

action_url/pnp4nagios/index.php/graph?host= $HOSTNAME $&srv=_host_

Register 0

}

Define Service {

Name Srv-pnp

action_url/pnp4nagios/index.php/graph?host= $HOSTNAME $&srv= $SERVICEDESC $

Register 0

}

Once the definition is complete, simply include the following in the defined hosts, services configuration file:

Define Host{

Use LINUX-SERVER,HOST-PNP; Name of host templates to use

; This host definition would inherit all variables that is defined

; In (or inherited by) the Linux-server host template definition.

HOST_NAME localhost

Alias localhost

Address 127.0.0.1

}

Define Service{

Use LOCAL-SERVICE,SRV-PNP; Name of service template to use

HOST_NAME localhost

Service_description PING

Check_command check_ping!100.0,20%!500.0,60%

}

So the entire configuration work is completed, access to the browser diagram is as follows
