Hello,
I'm trying to collect some performance data for Hosts and Services. All the services are showing Performance Data in the UI for Nagios Core but I don't see any files like service-perfdata, although the host-perfdata is there.

Here is the Nagios.cfg configurations:

Code: Select all

process_performance_data=1
# HOST AND SERVICE PERFORMANCE DATA PROCESSING COMMANDS

#host_perfdata_command=process-host-perfdata
#service_perfdata_command=process-service-perfdata

# HOST AND SERVICE PERFORMANCE DATA FILES

host_perfdata_file=/usr/local/nagios/var/host-perfdata
service_perfdata_file=/usr/local/nagios/var/service-perfdata

# HOST AND SERVICE PERFORMANCE DATA FILE TEMPLATES

host_perfdata_file_template=[HOSTPERFDATA]\t$TIMET$\t$HOSTNAME$\t$HOSTEXECUTIONTIME$\t$HOSTOUTPUT$\t$HOSTPERFDATA$
service_perfdata_file_template=[SERVICEPERFDATA]\t$TIMET$\t$HOSTNAME$\t$SERVICEDESC$\t$SERVICEEXECUTIONTIME$\t$SERVICELATENCY$\t$SERVICEOUTPUT$\t$SERVICEPERFDATA$


# HOST AND SERVICE PERFORMANCE DATA FILE MODES

host_perfdata_file_mode=a
service_perfdata_file_mode=a


# HOST AND SERVICE PERFORMANCE DATA FILE PROCESSING INTERVAL

#host_perfdata_file_processing_interval=0
#service_perfdata_file_processing_interval=0

# HOST AND SERVICE PERFORMANCE DATA FILE PROCESSING COMMANDS

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

The Plugins are showing performance data:

1.What configuration or commands I need to ad for all the plugins and services to output performance data (i.e. for Disk, CPU, and Memory)?
--An you give me an example?
2. How to make it specific for 1 or more services?
3. Does the host-perfdata only collect ping data?Or is it configurable for others?
4.What's the difference between service-perfdata and service-perfdata.out ?

Your help is appreciated.

After few tests with the config; I noticed that is I don't activate the data processing:
from

Code: Select all

# HOST AND SERVICE PERFORMANCE DATA PROCESSING COMMANDS
# These commands are run after every host and service check is
# performed.  These commands are executed only if the
# enable_performance_data option (above) is set to 1.  The command
# argument is the short name of a command definition that you
# define in your host configuration file.  Read the HTML docs for
# more information on performance data.

#host_perfdata_command=process-host-perfdata
#service_perfdata_command=process-service-perfdata

To

Code: Select all

host_perfdata_command=process-host-perfdata
service_perfdata_command=process-service-perfdata

I won't get the service-perfdata.out file.

The plugin determines if performance data is returned in the output, that's what generates the graphs automatically.

See here:

Code: Select all

http://nagios-plugins.org/doc/guidelines.html#AEN200

Here are the settings:

Code: Select all

service_perfdata_file=/usr/local/nagios/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::$SERVICESTATETYPE$\tSERVICEOUTPUT::$SERVICEOUTPUT$\tLONGSERVICEOUTPUT::$LONGSERVICEOUTPUT$
service_perfdata_file_mode=a
service_perfdata_file_processing_interval=15
service_perfdata_file_processing_command=process-service-perfdata-file
host_perfdata_file=/usr/local/nagios/var/host-perfdata

perfdata_timeout=5

Attach these files:

find / -name npcd.cfg
find / -name process_perfdata.cfg

Thanks for the reply @ssax

I can't find any of those

Code: Select all

find / -name npcd.cfg
find / -name process_perfdata.cfg

At the moment I installed Grafana over Nagios Core serverfollowing these instructions:
https://support.nagios.com/kb/article/n ... ana_Config

When I get to Adding a Query under "Grafana Configuration", I get an "Internal Server Error" pointing out the following:

Code: Select all

p>perfdata directory "/usr/local/nagios/share/perfdata/" is empty. Please check your Nagios config.

The nagios.cfg is pointing to a different location:

Code: Select all

host_perfdata_file=/usr/local/nagios/var/host-perfdata
service_perfdata_file=/usr/local/nagios/var/service-perfdata

Which location is the correct one for Nagios Core and for Grafana to pick it up properly?

Did you install PNP4Nagios on your Core server? It doesn't come with it installed, you'll need to manually set it up. As an example:

Posted: **Fri Jan 03, 2020 10:28 am**

PNP4Nagios is installed as part of the manual I posted earlier(https://support.nagios.com/kb/article/n ... ana_Config).

I'm getting the same error when I go to [url]http://<nagios_ip>/pnp4nagios/index.php/graph[/url]

Code: Select all

Please check the documentation for information about the following error.
perfdata directory "/usr/local/nagios/share/perfdata/" is empty. Please check your Nagios config. <a href="http://docs.pnp4nagios.org/faq/3">Read FAQ online</a>

file [line]:
application/models/data.php [109]:

Any ideas?

Could you post the full nagios,cfg file as well as the commands.cfg file so we can check the settings and commands?
I suspect the command that generated the service performance file may have an error.

It looks like you tried to install nagiosgraph on the server and the configurations for the performance data is pretty much mixed up and it not functioning at ll.

I would start over by first getting PNP4nagios running and after that is verified, then install Grafana.

Here are some instructions for installing PNP4Nagios
http://docs.pnp4nagios.org/pnp-0.6/start
If the system is going to monitor a log of Hosts and Services, I would use the Bulk mode with NPCD procedure for installing it.

There is also a KB article you can look at.
https://support.nagios.com/kb/article/n ... s-801.html

Remove the following from the nagios.cfg file before hand.

Code: Select all

# begin nagiosgraph configuration
# process nagios performance data using nagiosgraph
process_performance_data=1
service_perfdata_file=/tmp/perfdata.log
service_perfdata_file_template=$LASTSERVICECHECK$||$HOSTNAME$||$SERVICEDESC$||$SERVICEOUTPUT$||$SERVICEPERFDATA$
service_perfdata_file_mode=a
service_perfdata_file_processing_interval=30
service_perfdata_file_processing_command=process-service-perfdata-for-nagiosgraph
# end nagiosgraph configuration

And, remove the following from the commands.cfg file before re-installing PNP4Nagios

Code: Select all

define command {

    command_name    process-host-perfdata
    command_line    /usr/bin/printf "%b" "$LASTHOSTCHECK$\t$HOSTNAME$\t$HOSTSTATE$\t$HOSTATTEMPT$\t$HOSTSTATETYPE$\t$HOSTEXECUTIONTIME$\t$HOSTOUTPUT$\t$HOSTPERFDATA$\n" >> /usr/local/nagios/var/host-perfdata.out
}


define command {

    command_name    process-service-perfdata
    command_line    /usr/bin/printf "%b" "$LASTSERVICECHECK$\t$HOSTNAME$\t$SERVICEDESC$\t$SERVICESTATE$\t$SERVICEATTEMPT$\t$SERVICESTATETYPE$\t$SERVICEEXECUTIONTIME$\t$SERVICELATENCY$\t$SERVICEOUTPUT$\t$SERVICEPERFDATA$\n" >> /usr/local/nagios/var/service-perfdata.out
}

# begin nagiosgraph configuration
# command to process nagios performance data for nagiosgraph
define command {
  command_name process-service-perfdata-for-nagiosgraph
  command_line /usr/local/nagiosgraph/bin/insert.pl
}
# end nagiosgraph configuration

I did as you said and followed the instructions as from both articles:

Installed pnp4nagios from here : http://docs.pnp4nagios.org/pnp-0.6/install
Enable the configuration for Bulk Mode with NPCD :http://docs.pnp4nagios.org/pnp-0.6/conf ... _with_npcd

It seems to work now

Re-installed Grafana as per https://support.nagios.com/kb/article/n ... ana_Config

I'm not getting any Data in Grafana

All the files are present in this folder: /usr/local/pnp4nagios/var

What did I miss here?

Posted: **Tue Jan 07, 2020 1:53 pm**

Do you see the rrd files getting created in the sub folders of this folder?

Code: Select all

/usr/local/pnp4nagios/var/perfdata/

Or are the files in the sub folders of this folder?

Code: Select all

/usr/local/nagios/share/perfdata

What OS and Release is the server running?
