Callback functions and local facts.

[Marcin Prączko]

Hello,

I am trying to write my own callback function which logs information which I want to database, especially informations from local facts.
We have localfacts in json mode and I can easly get access to them from Ansbile it self, however everything what I've tried in terms access them from callback function failed.

Details:
- My callback function script skeleton is based on this callback script: http://jpmens.net/2012/09/11/watching-ansible-at-work-callbacks/
- I've search ansible group and found something similar - however didn't help solve my problem (https://groups.google.com/forum/#!topic/ansible-project/3GvdIIWCdSI)
- Looking in source (ansible / plugins / callbacks /) is not so helpfull for me as well.

So question, how I can get access to fact stored in local facts in callback functions:

1. These is a file on remote host:
/etc/ansible/facts.d/apache.fact

2. Return from this file (json format):
{
    "name": "apache",
    "status": "Installed",
    "version": "1.0.8"
}

3. Return this fact in ansible-playbook
"msg": "work - variable: {u'apache': {u'status': u'Installed', u'version': u'1.0.8', u'name': u'apache'}}"

4. Access to it from my callback function (Based on this callback which I mentioned above).
def log(host, data):
    if type(data) == dict:
        invocation = data.pop('invocation', None)
        if invocation.get('module_name', None) != 'setup':
            return

    facts = data.get('ansible_facts', None)

    now = time.strftime(TIME_FORMAT, time.localtime())

    try:
        # `host` is a unique index
        cur.execute("REPLACE INTO inventory (now, host, arch, dist, distvers, sys,kernel) VALUES(?,?,?,?,?,?,?);",
        (
            now,
            facts.get('ansible_hostname', None),
            ..... # !!!! Works well
        ))
        con.commit()

        cur.execute("REPLACE INTO modules (host, name, status, version) VALUES(?,?,?,?);",
        (
            # !!!!!! - Not working !!!!!
            facts.get('ansible_hostname', None),
            facts.get('ansible_local.apache.name', None),
            facts.get('ansible_local.apache.status', None),
            facts.get('ansible_local.apache.version', None),
        ))
        con.commit()

Summary:
Any reference to nasible_local.apache.name (etc) returns NULL in nasible callback function.


Please advice what I have to do, as I understand ansible_local is DICT in python, do I have to run some special functions to get access for facts in format: Main-fact-name.some-subname.some.... ???

Best regards,

Hi,

I think I sorted this our, seems be working now as expected:

This is a snipped which must be used for local facts:

ansible_local = facts.get('ansible_local', None)                                   

cur.execute("REPLACE INTO modules (host, name, status, version) VALUES(?,?,?,?);", 
(                                                                                  

  facts.get('ansible_hostname', None),                                           
  ansible_local["apache"]["name"],                                               
  ansible_local["apache"]["status"],                                             
  ansible_local["apache"]["version"]                                             
))                                                                                 

Best regards,

And still have question.

Is there any way to use facts_get with DICT?

For example:
facts.get('ansible_local["apache"]) ???

or

facts.get('ansible_interfaces["eth"].some_argument) ???

Best regards,

Hi!

This is really a question for ansible-devel, since this is about developing code that uses the API.  Can you post there?

Thanks!
