List of running processes form multiple linux hosts using with_items

[smitconsu...@gmail.com]

Hi 

I am trying to achieve all running processes on our linux machines via ansible and get output in a file along with each host name and processes. I have made below playbook but not getting to the point how to get list of processes for each host one by one and store in a file. Can anyone please help with the code how can I achieve this? I am using with_items with list of hosts which is coming from inventory group hostlist. many thanks

- hosts: all

  gather_facts: false

  tasks:

  - name: Get Running Processes

    command: ps -ef

    delegate_to: "{{ item }}"

    run_once: false

    with_items:

     - "{{ groups['hostlist'] }}"

    register: process_list

I just changed the host as devops

- hosts: devops

  gather_facts: no

  tasks:

    - name: Get the running process across the systems

      command: ps -ef

      register: output

    - name: Getting some details of systems

      local_action: copy content={{ output }} dest=/opt/{{ inventory_hostname }}file

Output::-

-------------

[root@ansible-master opt]# ls

192.168.56.111file  192.168.56.116file

HI Bishwajit Samanta

Thanks. It is creating file for each hostname but data is not in readable format. Are you able to do favor little more, how to get the data in each file as orignal form like as processes list show on linux machine? I was initially thinking to get output from all hosts in one file and somehow get processes list along with hostname one by one. But this can work as well. Many Thanks.

Replace {{ output }} with {{ output.stdout }}

To do that you need to use jinja template, something like this should work.

- name: Getting some details of systems

copy:
content: |
{% for i in ansible_play_hosts %}
Output for host {{ i }}:
{{ hostvars[i].output.stdout }}

{% endfor %}
dest: /my/file
delegate: localhost
