 Container Insights offers the ability to collect Syslog events from Linux nodes in your [Azure Kubernetes Service (AKS)](../../aks/intro-kubernetes.md) clusters. Customers can use Syslog for monitoring security and health events, typically by ingesting syslog into SIEM systems like [Microsoft Sentinel](https://azure.microsoft.com/products/microsoft-sentinel/#overview).
