Splunk is a platform where the machine-generated data from different platforms like websites, devices, and other CIs in the network can be analyzed, searched, and mapped for making sense in real-time. For example, say there is a continuous flow of data from one of the network devices, which requires it to be analyzed in real-time to take necessary action. Can Splunk help us with that? Yes. It can.
ServiceNow Event management is an offering of the Now Platform, which helps reduce the noise from different monitoring tools with the help of AIOps. In addition, the platform's machine learning is highly advanced compared to the legacy tools and capable of consolidating and taking action over the events brought in. Finally, like a cherry on the icing, it provides the impact analysis of the event to visualize the CIs involved and its course.
As the growth of machine data over the last few years was unimaginable, it's pretty clear that the world is moving towards IoT and other cutting-edge technologies out there. The data gathered from the IT infrastructure has a lot of information that can contribute to the overall productivity and efficiency. That's the purpose behind Splunk.
For one of the customers, Splunk was being used to provide analytics. They wanted to understand and identify the keywords that Splunk was capturing against their products. Here the purpose was not for triggering any alerts or automation but for keyword analysis. The data helped name and rename the products to make it easier for the customers.
Performing these operations over a huge terabyte of data is something that needs precision and efficiency. Making sense of the data log from a system is hard, most of the time. Even if it does, we end up spending a lot of time in word-by-word analysis. Machine data, to put it simply, is complex, noisy, unstructured. So instead of us, Splunk does the brainy work for us.
Once the data is analyzed and noise canceled, we need a place to push it for RCA, taking the necessary steps to prevent outages. Here comes ServiceNow's Event Management. With OOB functionalities like machine learning and Operational Intelligence, we can investigate issues in the infrastructure which may cause outages if not attended.
The Alert management helps perform the remediation, including the actions taken in the past on similar occasions. It provides the option to set up rules to automate the responses based on set conditions and criteria. For example, create an Incident or Change Request for the team to take necessary action. Even to trigger an automation to perform remediation, which was pre-built.
Splunk works well with ServiceNow, even without the Event management module. But that can cause duplicate entries as the incident is not created after going through the alert console. Instead, the operator workspace monitors the services in the environment. The Alert console keeps a watch on the alerts. It refreshes automatically as and when there is an update to the alert.

Once the alert from Splunk is captured in the ServiceNow platform, various actions can be initiated - both manually and automatically.
