[ansible-devel] complete ansible command line verbose like display using the python API

[Suren Baskaran]

Hi

So when we run a ansible playbook in command line with -vvv [ verbosity=3] 
we get all these below information like "Task path" , "using module" and 
the internals of how each hosts gets connectivity established.



TASK [SHOW THE LAST 10 ALERTS ] 
**
task path: 
Using module file 
/usr/lib/python2.7/site-packages/ansible/modules/commands/command.py
 ESTABLISH SSH CONNECTION FOR USER: 
 SSH: EXEC ssh -C -o ControlMaster=auto -o 
ControlPersist=60s -o KbdInteractiveAuthentication=no -o 
PreferredAuthentications=gssapi-with-mic,gssapi-keyex,hostbased,publickey 
-o PasswordAuthentication=no -o User=tpeng -o ConnectTimeout=10 -o 
ControlPath=XX '/bin/sh -c '"'"'echo ~ && sleep 0'"'"''
 (255, '', 'ssh: connect to host XX port 22: 
Connection timed out\r\n')
fatal: [gmcrou07.uk.db.com]: UNREACHABLE! => {
"changed": false,
"msg": "Failed to connect to the host via ssh: ssh: connect to 
host  port 22: Connection timed out\r\n",
"unreachable": true
}


Whereas when I set the same verbosity using the python API , I just an 
detailed info why the SSH failed to connect  like below


Failed to connect to the host via ssh: OpenSSH_7.4p1, OpenSSL 1.0.2k-fips

but not the other details , not sure if am missing any callback settings.

Appreciate some help here.

Re: [ansible-devel] Custom module to get list of open linux ports and running services

[Sam Doran]

Akash,

There is a service_facts 

 module that shipped in Ansible 2.5 that will list services. To get the open 
ports on a system, it would be much easier to write a custom facts module and 
parse the data rather than trying to parse the command output it in the 
playbook. You can use the run_command method to get the output, then parse it 
in Python, and return the results in a dictionary via the exit_json method.

Respectfully,

Sam Doran
