這個是把ansible的執行結果記錄下來，官網提供log，mail等方式。

這個哥們把它寫到sqlite裏了。

 

lib/ansible/callback_plugins/inventory.py

 

import os
import time
import sqlite3

dbname = '/etc/ansible/setup.db'
TIME_FORMAT='%Y-%m-%d %H:%M:%S'

try:
    con = sqlite3.connect(dbname)
    cur = con.cursor()
except:
    pass

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),
            facts.get('ansible_architecture', None),
            facts.get('ansible_distribution', None),
            facts.get('ansible_distribution_version', None),
            facts.get('ansible_system', None),
            facts.get('ansible_kernel', None)
        ))
        con.commit()
    except:
        pass

class CallbackModule(object):
    def runner_on_ok(self, host, res):
        log(host, res)

然後導出到csv文件

#!/bin/sh

sqlite3 /etc/ansible/setup.db <<EOF
.headers on
.mode csv
.output setup.csv
SELECT * FROM inventory;
EOF
