Splunk IT Service Intelligence (ITSI) is a powerful solution that helps numerous organizations achieve this by providing a practical data-driven approach to managing IT services and infrastructure. 

In this piece, we will cover:

Let’s get into the details.

What is Splunk ITSI?

Splunk IT Service Intelligence (ITSI) is a software solution provided by Splunk Inc., a leading provider of operational intelligence and data analytics software. Splunk ITSI is designed to help IT organizations gain insights into the performance and health of their IT services by monitoring, analyzing, and visualizing data from various sources in real time.

ITSI provides a centralized platform for IT teams to collect, index, and analyze machine data generated by various IT systems and infrastructure components, such as servers, applications, network devices, databases, and security tools. It uses machine learning and analytics capabilities to detect patterns, anomalies, and trends in the data, which can help IT teams identify and resolve issues proactively before they impact critical IT services.

With Splunk ITSI, IT organizations can set up service-oriented monitoring, define service-level agreements (SLAs), create dashboards and visualizations, and establish alerting and notification mechanisms for proactive IT service management. It provides advanced features such as event correlation, root cause analysis, predictive analytics, and capacity planning to enable IT teams to optimize the performance and availability of their IT services.

Splunk ITSI is widely used by IT operations, DevOps, and IT service management teams in enterprises of all sizes across various industries to monitor and manage their IT services, gain operational insights, and ensure high service quality for their users.

It helps IT teams make data-driven decisions based on historical trends and patterns, leading to better capacity planning, resource allocation, and performance optimization, resulting in cost savings and improved IT service delivery.

How to Implement Splunk ITSI Correctly

While implementing Splunk ITSI, it is essential to ensure that the implementation process follows best practices to extract maximum value. 

Here is an overview of how to set up a basic Splunk ITSI framework.

Step 1 – Pre-implementation preparation

Before you start the Splunk ITSI implementation process, clearly define your goals, identify the involved stakeholders, and assess if you have the resources necessary to complete the project. 

Next, identify all your critical IT services and infrastructure that needs monitoring. You then have to determine all your data sources and their access requirements. 

It is vital to ensure the necessary hardware and software infrastructure is in place during the Splunk ITSI pre-implementation prep phase.

Here are some tips to keep in mind:

  • Clearly define the goals and objectives of implementing Splunk ITSI, and ensure that all stakeholders are aligned on the expected outcomes.
  • Identify and engage key stakeholders, such as IT operations, security, and business teams, to gather requirements and ensure their buy-in throughout the implementation process.
  • Develop a detailed implementation plan with clear timelines, roles, and responsibilities to ensure the smooth execution of the project.

Step 2 – Data onboarding and normalization

Now that you have identified the various data sources in the pre-implementation preparation phase, it is time to collect the data from each source. It is essential here to normalize the data to ensure it is of a consistent format that Splunk ITSI can quickly analyze. 

Data onboarding can be difficult sometimes, so here are some helpful tips to minimize the struggle. 

  • Follow best practices for data onboarding, such as using appropriate data collectors, setting up data sources, and configuring data inputs to ensure data is ingested accurately and efficiently into Splunk ITSI.
  • Normalize data to ensure it is in a consistent format that Splunk ITSI can quickly analyze. Use data parsing, field extraction, and data enrichment techniques to ensure that data fields are properly extracted, formatted, and enriched with relevant information.

Step 3 – Defining and configuring services 

Your services are a set of interconnected hosts and applications, each offering a specific service to your organization that might have dependencies within one another. They can be your website, email system, or others. 

Defining and configuring these services in your Splunk ITSI environment is essential at this stage. 

Once you define and configure your services, you can create technical and business service models within your environment. You can additionally develop hierarchies in this stage.

Here are some actionable tips to ensure that you define and configure your services in the right manner. 

  • Clearly define and document the IT services that need to be monitored and managed using Splunk ITSI, including their dependencies and relationships.
  • Configure services in Splunk ITSI using the Service Analyzer to define key components, performance thresholds, and expected behaviors of each service.
  • Regularly review and update the service configurations to reflect changes in the IT environment, and ensure they align with the overall IT service management strategy.

Step 4 – Defining and baselining KPIs 

Each service contains Key Performance Indicators (KPIs) that will help you monitor individual aspects contributing to its health, such as health scores, root cause analysis, alerting, and compliance with SLAs. 

Glass tables are one of the most significant features of Splunk ITSI that allow you to monitor in real-time the dependencies and interrelationships between your KPIs. 

The Glass Tables can be programmed to feature multiple visualizations and charts of different KPIs and service health scores to give you a clear understanding of their health and performance. 

To get the best out of your services, define these KPIs and establish their baselines by identifying and benchmarking metrics vital to your company. 

The following are a few actionable steps to help you define the baselining KPIs smoothly. 

  • Define Key Performance Indicators (KPIs) that are aligned with the goals and objectives of the IT services being monitored in Splunk ITSI.
  • Establish baseline values for KPIs using historical data to provide a reference point for detecting anomalies and deviations from normal behavior.
  • Continuously monitor and update the baseline values as the IT services evolve, and adjust the KPI configurations accordingly to reflect changing performance expectations.

Step 5 – Creation and testing of correlation rules

Get the most out of the glass tables by creating correlation rules in Splunk ITSi to promptly detect issues within correlated services. They help identify relationships between data points to improve how well you predict problems. 

Testing your correlation rules’ accuracy before proceeding to the next step is essential. 

Follow these steps to ensure that the creation and testing of correlation rules are done correctly. 

  • Create correlation rules in Splunk ITSI to detect and correlate events and incidents across different IT services and components.
  • Test correlation rules in a controlled environment to validate their accuracy and effectiveness in identifying and correlating relevant events.
  • Refine and update correlation rules based on feedback from operational teams and ongoing analysis of incident data to continuously improve their performance.

Step 6 – Creating and managing alerts

Now that you have set up your KPIs and Dashboards to monitor your infrastructure, you must create and configure alerts in Splunk ITSI to notify you when service issues occur. 

Managing and configuring alerts to trigger specifically when certain conditions and thresholds are met is crucial. It ensures that you avoid alert fatigue and are notified when events occur.

However helpful you may find these tips, it is just an overview of setting up a basic Splunk ITSI framework. To optimally maximize the value of your Splunk ITSI environment, working with an experienced Splunk implementation partner, such as BitsIO, that has hands-on experience in implementing and customizing Splunk ITSI for countless businesses is recommended.

Below are some steps to follow to give you a hassle-free experience. 

  • Set up proactive alerts in Splunk ITSI based on correlation rules, KPI thresholds, or custom rules to notify relevant teams of incidents or anomalies.
  • Define clear and actionable alert messages with relevant information, such as severity level, impacted services, and recommended actions, to enable prompt and effective incident response.
  • Regularly review and update alert configurations to align with changing IT service requirements and ensure that alerts are relevant and actionable.
