The Splunk Industrial Control Systems (ICS) Essentials for Monitoring and Diagnostics provides common use cases relevant to ICS environments to enhance or augment current vendor tools. While many general IT monitoring cases also apply to ICS environments, this Essential focuses primarily on specific use cases for ICS. The goal for this essential is to help ICS teams understand the potential use cases around Splunk for Industrial IoT. Industrial control systems are complex real-time systems which are responsible for monitoring and controlling assets such as as oil and gas pipelines, manufacturing lines, mining operations, logistics, and other industrial processes. These systems are primarily focused on uptime and availability, reducing risk to human life, while maximizing production for an operator.
