Ansible AND SplunkLogging is a standalone feature introduced in Ansible Tower 3. Services connected to this data feed serve as a useful means in gaining insight into Tower usage or technical trends. The data can be used to analyze events in the infrastructure, monitor for anomalies, and correlate events from one service with events in another. The data is sent in JSON format over a HTTP connection using minimal service-specific tweaks engineered in a custom handler or via an imported library. Tower discards any uncaptured data if the logging aggregator is down. Below are special loggers except for awxwhich constitutes generic server logs that provide large amount of information in a predictable structured or semi-structured format, following the same structure as one would expect if obtaining the data from the API:. These loggers only use log-level of INFO, except for the awx logger, which may be any given level. Additionally, the standard Tower logs are be deliverable through this same mechanism. It is apparent how to enable or disable each of these five sources of data without manipulating a complex dictionary in your local settings file, as well as adjust the log-level consumed from the standard Tower logs. To configure various logging components in Ansible Tower, select System from the menu located on the left navigation bar. This logger reflects the data being saved into job events, except when they would otherwise conflict with expected standard fields from the logger, in which case the fields are nested. This is a intended to be a lower-volume source of information about changes in job states compared to job events, and also intended to capture changes to types of unified jobs other than job template based jobs. In addition to the common fields, this contains a msg field with the log message. Errors contain a separate traceback field. These values are entered in the example below:. In Sumologic, create a search criteria containing the json files that provide the parameters used to collect the data you need. If starting from scratch, standing up your own version the elastic stack, the only change you required is to add the following lines to the logstash logstash. Backward-incompatible changes were introduced with Elastic 5. If instead a URL is entered in host field Logging Aggregator fieldits hostname portion will be extracted as the actual hostname.

More times than not I have seen corporations struggle with config management and it is key for concise mitigation and remediation plan. Interfacing with a variety of Splunk customers the corporations whom do implement a config management system usually have a different tactic on how to manage Splunk while doing it in a secure fashion. In this series of blog posts which will hopefully walk you through a simple deployment of Ansible all the way to the most complex use-cases I have seen. I will first be covering how Ansible can be leverage to manage a simple Splunk deployment on your own hosts. Part 2 we will cover how this can be done in a larger scale with EC2 utilizing dynamically changing inventory of hosts for deployments whom need to scale in a cloud environment. The idea is to embark the necessary knowledge to not only deploy Splunk but anything else using Ansible as your config management system. There are a few config management system. The most common ones I have seen deployed are Chef and Puppet. In my previous job we evaluated a few of them, including Puppet and Chef and we ended up choosing Ansible. Here are the reasons why I have seen organizations make that choice:. Ansible is not for organizations whom their large server base is windows. Although they are working on Windows clients. I suggest you grab Ansible from their stable repo in github instead of your distributions repository. The stable version in github has welcomed updates and additions like ansible-vault which we will cover later in further detail. Below is a logical diagram which represents a high level Ansible application structure. Explanation of what the different pieces are:. Lets walk through the structure of a role in details. I will start with the common role. The common role should be ran no matter what kind of role the host has as it performs common functions that you would want on every host. If we look at the main. Lets walk though one of them and what does it do. Looking at apt. The description of this is at the top as a comment. The first batch install chkrootkit, rkhunter, clamav, fail2ban in the system and the second batch installs a set of configuration utilities vim,screen, etc. This is the typical structure of an Ansible play, which coordinates what happens on the host system. Plays are powered by different kind of Ansible modules, the one used above is apt module. You can see a full list of supported modules in Ansible docs. Before running Ansible make sure that your environment is set correctly. Make sure that you have hosts defined under hosts If the host you are running is virgin nothing has been done to it you will want to run Ansible with -k so it prompts for the password during the first run. You will only need this once as Ansible has a task under roles common to copy the ssh key of your user to that host. This should have armed you with the basic tools to do config management and orchestration on Splunk hosts as well as the rest of your infrastructure. I encourage you to walk through each roles task to verify what it is doing. Also the github read me will have more information as to how Splunk is configured using the shipped playbooks.
