Nagios::Contact fail: Cannot find command host_notify_by_email please define it first. about nagios

[sbotman]

I will take a look for you tomorrow.
Basically you first need to create the command.
It's probably an order issue with the data bag import.
But unable to check this at the moment.

Greetings sander

@sbotman thanks sander, also if i want to disable or limit the search by a attribute?

we want to create a nagios instance for each region. so usva should only find nodes that start with usva-. is there a way to disable finding things by environment and only find things by "region"?

[sbotman]

@blueharford Joshua, can you please test if this branch is working for you https://github.com/tas50/nagios/tree/fixing_353

About the search question:
We have disabled the default config and databag loading by setting the attributes within a wrapper cookbook:

default['nagios']['server']['load_default_config'] = false
default['nagios']['server']['load_databag_config'] = false

Then we use partial search (to offload the searches) to lookup the nodes and grab all the attributes that we would like to enable.

example:

nodes = []
multi_env = node['nagios']['monitored_environments']
multi_env_search = multi_env.empty? ? '' : ' AND (chef_environment:' + multi_env.join(' OR chef_environment:') + ')'

if node['nagios']['multi_environment_monitoring']
  nodes = partial_search(:node, "name:*#{multi_env_search}",
    :keys => { 'hostname' => ['hostname'],
               'name'     => ['name'],
               'fqdn'     => ['fqdn'],
               'os'       => ['os'],
               'family'   => ['platform_family'],
               'roles'    => ['roles'],
               'env'      => ['chef_environment'],
               'nagios'   => ['nagios'],
             }
  )
else
  nodes = partial_search(:node, "name:* AND chef_environment:#{node.chef_environment}",
    :keys => { 'hostname' => ['hostname'],
               'name'     => ['name'],
               'fqdn'     => ['fqdn'],
               'os'       => ['os'],
               'family'   => ['platform_family'],
               'roles'    => ['roles'],
               'env'      => ['chef_environment'],
               'nagios'   => ['nagios'],
             }
  )
end

nodes.each do |v|
  Chef::Log.debug("Nagios: Adding host to configuration with name: #{v['name']}")
  if v[node['nagios']['hostname_selection']].nil?
    host = Nagios::Host.create(v['name'])
  else
    host = Nagios::Host.create(v[node['nagios']['hostname_selection']])
  end

  groups = v['roles'].nil? ? [] : v['roles']
  groups += [v['os']] unless v['os'].nil?
  groups += [v['env']] unless v['env'].nil?

  groups.each do |group|
    hg = Nagios::Hostgroup.create(group)
    hg.push(host)
    host.push(hg)
  end

end

search(:role, '*:*') do |role|
  Nagios::Hostgroup.create(role.name)
end

Something like this.... If this doesn't help you then we might need to talk about this :)

hmm so i want the databags to be used but i just want to customize the search for what gets added.

so all databags load, but when it searches for nodes in chef, instead of it looking by environment i'd like it to look at the first 3 letters of the node name for matching.

@sbotman it works if i add pagerduty as a contact.. but then it doesnt configure it right as defined in pagerduty.rb . should default.rb be calling pagerduty.rb if so where?

[sbotman]

Hi Joshua, did you also test the branch https://github.com/tas50/nagios/tree/fixing_353 ?

[blueharford]

@sbotman i grabbed the last commit then made the change. but im not finding it clear on how to invoke pagerduty.

im seeing this in the contacts.cfg

Skipping pagerduty because missing email.

[blueharford]

@sbotman ok so apparently it created a pagerduty.conf with the contact. so i had to add include_recipe "nagios::pagerduty" in default right before the update resource and all is happy.

[sbotman]

Great!

To be very honest, I personally never used the data bag setup. And if we use it, we don't do very much with it. Yesterday GitBytes opened issue #354 which took me some time to fix. Think that these changes are also useful for your setup and it would be great if you can test that branch. The fix provided here above is also merged into that branch.

Please let me know the result :)

Cheers Sander

[blueharford]

@sbotman yea it works. the only issue i have now. is that i dont want it to scan by environment. i'd likefor their to be an option where i can do default['nagios']['node']['hostname_match'] = 'b1p' would only auto add servers that node name starts with b1p. since we have mutltiple regions

[sbotman]

@blueharford if you have setup your chef-environments per region, then you can use the following attributes:

default['nagios']['multi_environment_monitoring'] = false
default['nagios']['monitored_environments'] = []

Otherwise you will need to create some custom code like the example I gave here above.
The configuration is fully provider driven and you can put all your needs within recipes, please check the wiki https://github.com/tas50/nagios/wiki. If this still doesn't help you, you can contact me on skype under [email protected] and I will help you.

Cheers Sander
