Ansible Logging Outout

Netmart — Mon, 11 Sep 2023 04:00:21 GMT

Hello,

To my understanding, the output will be printed on the screen.

I would like save it under a log file.

I tried to add it to ansible.cfg file, but still I am not able to see the log file:

[default]

#some basic default values...

nocows=true

#log_path=/etc/ansible/logs/ansible_log.txt

log_path=./ansible_log.txt

callbacks_enabled=ansible.posix.profile_tasks

stdout_callback=ansible.posix.json

inventory = $HOME/.ansible/hosts

remote_tmp = $HOME/.ansible/tmp

forks = 150

sudo_user = root

transport = smart

host_key_checking = False

Thanks,

Netmart

Hi, the log_path directive is correct. See this basic example:

ansible.cfg

[defaults] log_path=./ansible.log

playbook (test.yml)

- name: test logging hosts: localhost gather_facts: false tasks: - name: a test debug message ansible.builtin.debug: msg: "This is a debug ouput"

this will create a log file ansible.log with the following content:

maercu@CHLT303344:~/dev/tmp$ cat ansible.log 2023-09-11 07:58:11,656 p=699 u=maercu n=ansible | [WARNING]: No inventory was parsed, only implicit localhost is available 2023-09-11 07:58:11,660 p=699 u=maercu n=ansible | [WARNING]: provided hosts list is empty, only localhost is available.

Thank you Marcel.

I tried and got the following in the logs:

$ cat ansible.log

2023-09-11 07:58:11,656 p=699 u=cisco n=ansible | [WARNING]: No inventory was parsed, only implicit localhost is available

2023-09-11 07:58:11,660 p=699 u=cisco n=ansible | [WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match 'all'

}

2023-09-11 07:58:11,796 p=699 u=cisco n=ansible | localhost : ok=1 changed=0 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0

My goal was to capture the show output of the following runbook. So not sure, if this does require a different type of logging:

site.yml file

---

- name: Test Ansible ios_command on Cisco IOS XE

hosts: iosxe

tasks:

- name: show version and ip interface brief

ios_command:

commands:

- show version

- show ip interface brief

I would appreciate any advice.

Thanks,

Netmart

In that case you need to register and print (debug) the result of your task - something like that:

- name: Test Ansible ios_command on Cisco IOS XE hosts: iosxe tasks: - name: show version and ip interface brief ios_command: commands: - show version - show ip interface brief register: output - name: print result debug: var: output.stdout

Doing so, you should see the output on screen as well as in your log file.

Thank you Marcel.

Yes, it does print output on screen plus append it to ansible.log file

Is it possible to save the output as separated file as txt, yaml, or even json.

Also, when I tried to run "show license feature", it seems that the loaded ansible collect is not support it.

tasks:

- name: show license feature

ios_command:

commands:

- show license feature

The error you receive is because of the host key checking (https://docs.ansible.com/ansible/2.8/user_guide/intro_getting_started.html#host-key-checking), to disable it, disable host key checking in your ansible.cfg:

[defaults] log_path=./ansible.log host_key_checking = False

To collect json parsed output, I usually use the cli_parse module (https://docs.ansible.com/ansible/latest/collections/ansible/utils/cli_parse_module.html) with pyats/genie, to use it you may need to install the collection + libary:

ansible-galaxy collection install ansible.utils pip install pyats

Once done you can use it, here is an example:
inentory

all: hosts: sandbox-iosxe-latest-1.cisco.com: vars: ansible_user: admin ansible_password: C1sco12345 ansible_network_os: cisco.ios.ios ansible_connection: ansible.netcommon.network_cli

playbook

- name: Log outputs to file hosts: sandbox-iosxe-latest-1.cisco.com gather_facts: false tasks: ### GET AND SAVE TXT OUTPUT ######################### - name: Run command cisco.ios.ios_command: commands: - show license usage register: output - name: Print result as txt debug: var: output.stdout[0] - name: Save result as txt to file hostname_output.txt ansible.builtin.copy: content: "{{output.stdout[0]}}" dest: "{{inventory_hostname}}_output.txt" ### GET AND SAVE JSON OUTPUT ######################## - name: Run command and parse with genie ansible.utils.cli_parse: command: show license usage parser: name: ansible.netcommon.pyats register: output - name: Print Result as json ansible.builtin.debug: var: output.parsed - name: Save result as json to file hostname_output.json ansible.builtin.copy: content: "{{output.parsed}}" dest: "{{inventory_hostname}}_output.json"

Thank you Marcel.

Eventually I used:

tasks:

- name: show license all

ios_command:

commands:

- terminal length 0

- terminal width 200

- show license status

become: true

- name: print result

debug:

var: output

And directed the output to a text file:

ansible-playbook -i hosts site-iosxe-lic-enable-vault.yml -u cisco-k > site-iosxe-lic.txt
