Collecting Data from ServiceNow in Splunk

Let's discuss how to collect data from your ServiceNow instance in Splunk. First, what is ServiceNow? ServiceNow is a maker of service management software that can be on-prem or in the cloud.

Growing your Splunk Deployment

Intro

Growth.  It's important in so many aspects of our lives; from our careers, health, and relationships.  The famed motivational, self-help guru Tony Robbins says that beyond our basic needs, we need growth and giving back in order to truly be fulfilled.  In addition to adding to ourselves, sometimes growth requires us to rebuild a portion of ourselves.  Well, Splunk is no different.  In order for it to keep it's self-esteem high, it also needs to grow.

Stepping Up with Splunk!

“Surround yourself with the dreamers and the doers, the believers and thinkers, but most of all, surround yourself with those who see greatness within you, even when you don’t see it in yourself.” –Edmund Lee

Splunk: Modular Inputs

I often blog about Drupal, but recently I worked on a Splunk App, so thought about sharing my experience because it was an interesting one.  For that Splunk App, I was on the Function1 Slack channel posting an endless stream of Splunk related questions and my colleagues provided tremendous support, patiently responding to my non-stop inquiries.
