Graph is not showing in Nagios

[imran_khan]

Hello,

Thanks for the reply. Please reply to my additional query.

Thanks,
Imran Khan.

Where should I make below changes, means in which file. Please give me file name with full path. I have tried in many files but no luck.

As per your nagios.cfg file you are using the following config files:

Code: Select all

cfg_file=/usr/local/nagios/etc/objects/Linux-Team/linux-hosts.cfg
cfg_file=/usr/local/nagios/etc/objects/Linux-Team/linux-services.cfg

In the linux-hosts.cfg file you will need to add to each host definition:

Code: Select all

use                     host-pnp

In the linux-services.cfg file you will need to add to each service definition:

Code: Select all

use                     srv-pnp

You would need to repeat this for each type (Corp-Team, Routers-Switches etc etc).

Also, as per your nagis.cfg file:

Code: Select all

host_perfdata_file_processing_command=process-host-perfdata-file
service_perfdata_file_processing_command=process-service-perfdata-file

There should be definitions in your /usr/local/nagios/etc/objects/Defination/commands.cfg as follows:

Code: Select all

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.$TIMET$
}

Hello,

I have tried mentioned setting many times and getting below error very time when verified nagios configuration using /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg command. Please suggest me on the same.

Reading configuration data...
Read main config file okay...
Error: Template 'host-pnp' specified in host definition could not be not found (config file '/usr/local/nagios/etc/objects/Linux-Team/linux-hosts.cfg', starting on line
28)
Error processing object config files!

Also command.cfg definition is as below.

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
}

Thanks,
Imran Khan.

Can you please show us a host definition from '/usr/local/nagios/etc/objects/Linux-Team/linux-hosts.cfg' that has the line "use host-pnp".

[imran_khan]

Hello,

Please find the host definition details.

# example.com' host definition
define host{
use generic-host,host-pnp ; Name of host template to use
host_name example.com
alias example.com
address Server_IP
address Server_IP
check_command check-host-alive
max_check_attempts 10
notification_interval 10
notification_period 24x7
notification_options d,u,r
hostgroups ABCD,PQRST
notes_url /nagios/info/windows.html
contact_groups linuxteam
}

Thanks,
Imran Khan.

[Box293]

I have put the below content in /usr/local/nagios/etc/objects/Defination/templates.cfg file.

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
}

Your nagios.cfg file does not have a reference to /usr/local/nagios/etc/objects/Defination/templates.cfg

Add the following to nagios.cfg

Code: Select all

cfg_file=/usr/local/nagios/etc/objects/Defination/templates.cfg

And then run this to validate your configuration:

Code: Select all

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

If all is good restart Nagios.

Hello,

Added mentioned template path in nagios configuration file. now getting below error.

It looks like you copied an existing template file and used it for Defination/templates.cfg.

I would:

• Make a backup copy of the file
  Remove all entries in the file except for:

  Code: Select all

  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
      }

  Validate the configuration:

  Code: Select all

  /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
