I’d like to set downtime in Nagios for several hosts at once using the Nagios module. How do I specify those several hosts?

```auto
- nagios: action=downtime minutes=30 service=all host=?

```

Many thanks.

you can do:

- nagios: action=downtime minutes=30 service=all host={{item}}  
&nbsp;&nbsp;with\_items: "{{ listofhosts }}"

or if it is a specific ansible inventory group:

- nagios: action=downtime minutes=30 service=all host={{item}}  
&nbsp;&nbsp;with\_items: "{{ groups['specificgroup'] }}"

Excellent - thank you, Brian!

Oh, Brian, is the {{ listofhosts }} just a space-delimited list?

</div>

its a list

listofhosts:  
&nbsp;&nbsp;- host1  
&nbsp;&nbsp;- host2

or

listofhosts: ['host1', 'host2', ....]

Sorry I’m asking Ansible 101 questions, but my play isn’t working:

tasks:

- nagios: action=downtime minutes=5 author=“My Name” service=all host={{item}}  
with\_items: “{{ listofhosts }}”  
listofhosts:
- summitauto  
delegate\_to: nagios\_server  
tags:
- nagios\_downtime

I guess I don’t know where to put my list. Also not sure if “author” belongs where I have it.

you cannot define it that way, you either predefine the list in a  
vars: or vars\_file or just do it like this:

&nbsp;&nbsp;tasks:  
&nbsp;&nbsp;&nbsp;&nbsp;- nagios: action=downtime minutes=5 author="My Name" service=all  
host={{item}}  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;with\_items:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- summitauto  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;delegate\_to: nagios\_server  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tags:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- nagios\_downtime

</div>

When I try that, I get the following errors:

fatal: [host1 → nagios\_server] =\> Authentication failure.  
fatal: [host2 → nagios\_server] =\> Authentication failure.  
fatal: [host3 → nagios\_server] =\> Authentication failure.  
changed: [host4 → nagios\_server] =\> (item=summitauto)  
changed: [host5 → nagios\_server] =\> (item=summitauto)  
changed: [host6 → nagios\_server] =\> (item=summitauto)

That’s clearly not what I’m after. The beginning of the playbook looks like this:

- hosts: all  
gather\_facts: false  
sudo: yes

and I run the playbook like this: ansible-playbook someplaybook.yml --tags “nagios\_downtime” -u sudoacct

Thanks for your continuing help.

I didn’t realize that I needed to create a separate play in my playbook to do this piece. Once I did that, everything worked as advertise. Sorry that my learning mistakes have created noise. Thanks, again, to Brian Coca for all the help - greatly appreciated!
