Creating McAfee ePO Alert and ARF Actions with Add-On Builder
One of the best things about Splunk is the passionate user community. As a group, the community writes amazing Splunk searches, crafts beautiful dashboards, answers thousands of questions, and shares apps and add-ons with the world.
Building high quality add-ons is perhaps one of the more daunting ways to contribute. Since the recently-updated Splunk Add-On Builder 2.0 was released, however, it’s never been easier to build, test, validate and package add-ons for sharing on SplunkBase.
Technical Add-Ons, aka TAs, are specialized Splunk apps that make it easy for Splunk to ingest data, extract and calculate field values, and normalize field names against the Common Information Model (CIM). Since the release of version 6.3, Splunk Enterprise also supports TAs for …
Important information for customers using Splunk Enterprise 6.2 or earlier
Do you use SSL to secure Splunk Enterprise? Are you still using Splunk Enterprise version 6.2 or earlier? If you answered yes to both of these questions, please read on.
Securing communication with your Splunk instance can be essential in today’s digital environment, especially if it is collecting sensitive information. If communication to/from your Splunk instance can be easily intercepted (e.g. public access to SplunkWeb, Forwarders outside firewall) then this communication should be encrypted using SSL. Additionally, security functionality is constantly being enhanced to combat the evolving threat landscape so you should stay on as current a version of Splunk as possible.
You may have heard that the OpenSSL Software Foundation will cease support for OpenSSL version 1.0.1 as …
Building add-ons just got 2.0 times easier
Are you trying to build ES Adaptive Response actions or alert actions and need some help? Are you trying to validate your add-on to see if it is ready to submit for certification? Are you grappling with your add-on setup page and building credential encryptions? If you are, check out Splunk Add-on Builder 2.0.
Below is a brief overview of what’s new in Add-on Builder 2.0:
- You can now leverage the easy-to-use, step-by-step workflow in Add-on Builder to create alert actions and ES adaptive response actions. No need to deal with .conf files and Python, let the tool do the work for you.
- The validation process has been enhanced to include App Certification readiness. This validation process can also be performed on apps and add-ons
Encrypt a Modular Input Field without using Setup.XML
Modular Inputs are a great addition to Splunk Enterprise. One of the things I really like about Modular Inputs is that they allow you to create inputs that “look and feel” as if they were part of the Splunk installation by providing a nice user interface for parameter input.
But, what if you need to encrypt a Modular Input value? This could be a password, OAuth secret key, or some other confidential piece of information. Traditional Splunk applications use setup.xml and the storage/passwords endpoint to accomplish this. If you just need to encrypt an input value specific to the input (as opposed to the entire application), it may be cumbersome to the end user to first run through a setup.xml …
Introducing Splunkbase Curated Experience
There are about 1,200 apps in Splunkbase today. Up until now, the typical ways to look for an app on Splunkbase have been to either search for the app, or filter through multiple apps based on several filter criteria. We have not recommended apps to our user community in the past. With the launch of curated experience at Splunk .conf2016 we are changing this by bringing the notion of “curation” to Splunkbase.
We believe this will improve the app browsing and discovery experience for our users by highlighting apps that provide the most value. The main emphasis here is on “curation of content” by a team at Splunk – sifting through all the apps on Splunkbase, and highlighting these …
Yesterday at .conf2016 we announced the general availability of Splunk AppInspect, the first static and dynamic analysis tool for Splunk apps. Built and used by the team that administers the Splunk App Certification program to speed the certification process, we’re now able to share it with developers who want the same insights into their apps, whether they plan to release them to Splunkbase or not.
“AppInspect has been invaluable in bringing Splunk certification testing into our automated build environment, helping us to create Splunk Apps that are ready for App Certification on the first upload to SplunkBase.” – Kyle Smith, Aplura, LLC
All developers want to get their work done faster, with fewer errors and less debugging. Splunk AppInspect makes that possible …
Splunk your Google Analytics
Gain more insight into site performance and user activity by correlating Google Analytics data within Splunk.
A customer of mine recently wanted to understand more about the journey that retail consumers take when they arrive at its website. They recognized that consumers who have previously bought from the site will have more familiarity with the design and layout than those visiting the site for the first time. In addition, consumers who went directly to the site would have a greater brand engagement than those who were referred from an affiliate site.
If only we could implement a method to back up the data that gets submitted to Google Analytics, also sending it back to the local Apache web server logs …
I can’t make my time range picker pick my time field.
When you are working with Hadoop using Hunk or when you are working with Splunk and the time field you want to work with is not _time, you may want to use the time picker in a dashboard with some other time field. You may have the same problem when the current _time field is not the time field you want to use for the current search.
Here is a solution you might use to make time selections work in every case including in panels.
| inputlookup SampleData.csv | eval _time=strptime(claim_filing_date,"%Y-%m-%d") | sort - _time | addinfo | where _time>=info_min_time AND (_time<=info_max_time OR info_max_time="+Infinity")
Let’s Break this search down into its parts.
| inputlookup SampleData.csv
This is an example of …
Talk to Splunk with Amazon Alexa
What do you think the future experience of interacting with your data is going to be like ? Is it going to be logging in by way of a user interface and then using your mouse/keyboard/gestures to view and interact with something on a display panel , or is it going to be more like simply talking with another person ?
Introducing the “Talk to Splunk with Amazon Alexa” App
This is a Splunk App that enables your Splunk instance for interfacing with Amazon Alexa by way of a custom Alexa skill, thereby provisioning a Natural Language interface for Splunk.
You can then use an Alexa device such as Amazon’s Echo,Tap or Dot or another 3rd party hardware device to tell …
