notifying the nrpe service to reload itself does not work correctly

[5c077yP]

Hey,

i'm using ubuntu 12.04LTS and the

file "#{node['nrpe']['conf_dir']}/nrpe.d/#{new_resource.command_name}.cfg" do
  ...
  notifies :reload, 'service[nrpe]'
end

within the check lwrp doesn't work for me. It always just says:

Recipe: nrpe::default
  * service[nagios-nrpe-server] action reload (up to date)

And using the check_nrpe plugin can't find configured commands until i restart nrpe by hand.

I'm installing nrpe using the source method and the provided init script doesn't support reload as a command, maybe this is the real problem here, not sure.

Sorry ... it was just not working in my vagrant environment, but is on real servers :?

Hi i have the same problem, nrpe is never restated, my 'notifies' are completely ignored. no matter what i try, i'm forced to restart it manually everytime. i'm using debian VMs hosted on AWS, and created a check for ntp monitoring. how can i make nrpe service to restart after adding new checks ? thanks

here's my recipe:

nrpe_check "check_ntp_monitoring" do
  command "#{node['nrpe']['plugin_dir']}/check_ntp_time"
  parameters '-H 0.amazon.pool.ntp.org -c 5 -w 1'
  action :add
  notifies :restart, "service[#{node['nrpe']['service_name']}]", :delayed
end

i've tryed to go on the VM, manually delete /etc/nagios/nrpe.d/check_ntp_monitoring.cfg, then, launch a chef-client. the check is re-created (that's good) but nrpe service is not restarted (that's the bad point). here's the output i get:

* file[/etc/nagios/nrpe.d/check_ntp_monitoring.cfg] action create

also i can confirm nrpe is not restarted by check the age of the nrpe process with: stat /proc/nrpe_pid it is older than the chef-client run. as far as i can tell, nrpe process start fine, but it is never restarted. please tell me what kind of info you need, i can provide logs, i can help and test too. this problem is reproductible i have it on all my 50+ VMs (all debian 6.x)

thanks

Hey,

i just tested it on a ubuntu 12.04 vm and have the same issue. I'm installing nrpe from source in version 2.15. For me it seems that the reload command for the init script didn't work because there was no pid file. A quick check shows the pid directory /var/run/nagios does not exist and the nagios-nrpe-server is not creating it when started (although pid file is configured in config). If I create that directory within my recipe all works now. But /var/run is cleared a boot time, which is why i would not create the dir through chef, but change the pid file location:

# set this in your attributes file or wherever
default['nrpe']['pid_file'] = '/run/nagios.pid'

[5c077yP]

maybe we should update the cookbook attributes accordingly?

[5c077yP]

for debian squeeze use /var/run/nagios.pid

thanks for the reply! i will test that tomorrow, and report back how it went for me. in the meantime i just added a bash block in my recipe, scanning for directory /etc/nagios/nrpe.d/* and if any file age was less than 10mn restart nrpe service (through bash). if no file age was less that 10mn do nothing. that worked for me but that would be better if it was fixed directly in the cookbook.

thanks again
