icinga2, erro pnp4nagios: “RRDs :: create ERROR você deve definir pelo menos um Round Robin Archive”

Question

Não consigo pnp4nagios trabalhar com icinga2 no ubuntu 14.04 usando o mais recente commit do chef- livro de receitas icinga2.

Defino pnp = true em meu livro de receitas wrapper e o icinga2 :: server_pnp receita é executada com sucesso.

attributes / default.rb

default['icinga2']['version'] = '2.4.4-1'
default['icinga2']['classic_ui']['enable'] = true
default['icinga2']['classic_ui']['version'] = '2.4.4-1'
default['icinga2']['pnp'] = true

Os serviços estão todos em execução e podem ser reiniciados com sucesso.

root@icinga2-host:~# service icinga2 status
 * icinga2 is running
root@icinga2-host:~# service apache2 status
 * apache2 is running
root@icinga2-host:~# service rrdcached status

A pasta /var/spool/icinga2/perfdata está vazia.

Eu só vejo arquivos xml na pasta cache:

Eu tentei usar a ferramenta verify_pnp_config mas não consegui encontrar o arquivo de configuração correto para passar para então sempre recebo o mesmo erro (tentei process_perfdata.cfg, rra.cfg e npcd.cfg):

root@icinga2-host:/usr/local/pnp4nagios# wget http://verify.pnp4nagios.org/verify_pnp_config

Alguém sabe onde eu deveria ir daqui? Obrigado!

    

Answer 1

O livro de receitas icinga2 usa o pnp4nagios livro de receitas.

O atributo padrão ['pnp4nagios'] ['rra'] no livro de receitas pnp4nagios é um valor vazio:

default['pnp4nagios']['rra'] = []

Portanto, o padrão /etc/pnp4nagios/rra.cfg criado pela receita icinga2 :: server_pnp não é uma configuração válida:

# Define the default RRA Step in seconds
# More Infos on
# http://oss.oetiker.ch/rrdtool/doc/rrdcreate.en.html
#
RRA_STEP=60
#
# PNP default RRA config
# you will get 400kb of data per datasource
# 2880 entries with 1 minute step = 48 hours
# RRA:AVERAGE:0.5:1:2880
# 2880 entries with 5 minute step = 10 days
# RRA:AVERAGE:0.5:5:2880
# 4320 entries with 30 minute step = 90 days
# RRA:AVERAGE:0.5:30:4320
# 5840 entries with 360 minute step = 4 years
# RRA:AVERAGE:0.5:360:5840

# RRA:MAX:0.5:1:2880
# RRA:MAX:0.5:5:2880
# RRA:MAX:0.5:30:4320
# RRA:MAX:0.5:360:5840

# RRA:MIN:0.5:1:2880
# RRA:MIN:0.5:5:2880
# RRA:MIN:0.5:30:4320
# RRA:MIN:0.5:360:5840

Adicionando o seguinte aos atributos padrão no meu livro de receitas wrapper, /etc/pnp4nagios/rra.cfg obtém uma configuração válida e tudo funciona.

attributes / default.rb

default['pnp4nagios']['rra'] = %w(RRA:AVERAGE:0.5:1:2880 RRA:AVERAGE:0.5:5:2880 RRA:AVERAGE:0.5:30:4320 RRA:AVERAGE:0.5:360:5840 RRA:MAX:0.5:1:2880 RRA:MAX:0.5:5:2880 RRA:MAX:0.5:30:4320 RRA:MAX:0.5:360:5840 RRA:MIN:0.5:1:2880 RRA:MIN:0.5:5:2880 RRA:MIN:0.5:30:4320 RRA:MIN:0.5:360:5840)

Válido /etc/pnp4nagios/rra.cfg :

# Define the default RRA Step in seconds
# More Infos on
# http://oss.oetiker.ch/rrdtool/doc/rrdcreate.en.html
#
RRA_STEP=60
