Dimitri, the play does what you want. The code is available also here
https://gist.github.com/vbotka/10c57962976dd1e2dd3e9411d3745c75
Let me help you to understand it step by step
>>> - hosts: test_01,test_05,test_06,test_07
>>> gather_facts: false
There are 4 hosts in the play. Setup is off, hence no connections to
the remote host up till now
>>> vars:
>>>
>>> h_unr: "{{ dict(ansible_play_hosts_all|
>>> zip(ansible_play_hosts_all|
>>> map('extract', hostvars, 'unr'))) }}"
This dictionary will be evaluated when referenced in the debug task
>>> tasks:
>>>
>>> - block:
>>> - ping:
>>> register: out
>>> - set_fact:
>>> unr: "{{ out.unreachable|d(false) }}"
>>> ignore_unreachable: true
Here come the first connections to the remote hosts. There are 2
tasks in the block. The first one is the Ansible module ping, not the
ICMP ping. (Yes, you're right. There is a difference.) The second one
is the module set_fact. Because of the ignore statement the tasks in
the block won't fail if a host is unreachable.
If a host can be reached by ping there is no attribute *unreachable*
in the registered dictionary *out*. Therefor, the value of the
variables *unr* will be the default (alias d) value *false*.
If a host can't be reached the value of the attribute *unreachable*
is *true*.
>>> - debug:
>>> var: h_unr
>>> run_once: true
>>> delegate_to: localhost
Here is the report. Let's analyse the dictionary *h_unr*. In the
above block, all hosts created the variable *unr*. When you take the
list of all hosts in the play *ansible_play_hosts_all* [1] and *map*
the function to *extract* the *hostvars* [2] variable *unr*
ansible_play_hosts_all|map('extract', hostvars, 'unr')
you get a list, for example, where only the first host was reached
[false, true, true, true]
Then, *zip* this list with *ansible_play_hosts_all*
[[test_01,false], [test_02,true], [test_03,true], [test_04,true]]
and apply the function *dict* [3]. Below is the expected result.
Enjoy!

Ignore unreachable hosts in a block
- block:
- ping:
register: out
- set_fact:
unr: "{{ out.unreachable|d(false) }}"
ignore_unreachable: true
and declare the dictionary
h_unr: "{{ dict(ansible_play_hosts_all|
zip(ansible_play_hosts_all|
map('extract', hostvars, 'unr'))) }}"
For example, the below play
- hosts: test_01,test_05,test_06,test_07
gather_facts: false
vars:
h_unr: "{{ dict(ansible_play_hosts_all|
zip(ansible_play_hosts_all|
map('extract', hostvars, 'unr'))) }}"
tasks:
- block:
- ping:
register: out
- set_fact:
unr: "{{ out.unreachable|d(false) }}"
ignore_unreachable: true
- debug:
var: h_unr
run_once: true
delegate_to: localhost
gives (abridged)
ok: [test_01 -> localhost] =>
h_unr:
test_01: false
test_05: true
test_06: true
test_07: true

Re: [ansible-project] Ansible ping report
Vladimir, this is very good, and very appreciated. Your playbook looks for
hosts that are pingable, and marks them as not unreachable. But, my goal
is to see if hosts are Ansible-pingable (not ICMP-pingable; I believe
there's a difference) or not, then take *all* of the output, and create a
report from it. Thus, i end up with a report of hosts that are either
Ansible-pingable or not.

Re: [ansible-project] Ansible ping report
Thanks, Brian. I suspected that was the case (I did read doc for the module), but was hoping there was some work-around. I'm still interested in trying to generate some type of report from Ansible ping. As you can see from the playbook I posted, that uses ICMP ping, which is not what I'm after.

[ansible-project] Ansible ping report
Hi, All.
It's been some time since I used Ansible, and this list. I'm happy to be
back using both.
I've created a [playbook to run pin, and create a report of output:
---
- name: check reachable hosts
hosts: dytest
gather_facts: no
tasks:
- name: Ping each host
ansible.builtin.command: ping -c1 {{ item }}
run_once: true
loop: "{{ ansible_play_hosts_all }}"
delegate_to: localhost
register: ping_result
failed_when: false
- name: How did we do?
ansible.builtin.debug:
msg: "{{ ping_result.results[0] }}"
run_once: true
- name: Format it a bit
# Note: the docs for 'copy' say don't do this, to use template instead,
# and there are reasons, but this suffices for posting purposes.
# The 'content:' below should be in your template.
ansible.builtin.copy:
dest: /home/deploy/ping.txt
content: |
--- PING REPORT ---
{% for pr in ping_result.results %}
{{ pr.stdout_lines | first }}
{{ pr.stdout_lines | last }}
{% endfor %}
run_once: true
delegate_to: localhost
That works fine. However, I want to use ansible.builtin.ping, not regular
ping. When I substitute in ansible.builtin ping, I get the error:
fatal: [bed-test-9-dy1]: FAILED! => {"msg": "The task includes an option
with an undefined variable. The error was: 'dict object' has no attribute
'stdout'. 'dict object' has no attribute 'stdout'\n\nThe error appears to
be in '/etc/ansible/playbooks/ping4.yml': line 15, column 7, but may\nbe
elsewhere in the file depending on the exact syntax problem.\n\nThe
offending line appears to be:\n\n\n- name: How did we do?\n
What do I need to do to accomplish what I'm after?
Many thanks.
