Enhancing cloud observability: NETSCOUT unveils KlearSight

NETSCOUT SYSTEMS, INC., has announced an innovation aimed at meeting organisations’ increasing needs for comprehensive observability within complex cloud environments.

With the ever-growing demands of large, multi-cluster Kubernetes deployments, organisations reportedly often face significant challenges related to visibility and blind spots in their environments.

Omnis KlearSight Sensor for Kubernetes (KlearSight) is said to deliver deep, actionable and real-time insights into system performance, health and cost drivers.

This solution is specifically designed to support dynamic and distributed architectures, environments that are challenging to monitor due to their encrypted nature.

Providing robust visibility

KlearSight is said to capture Kubernetes packets and SSL messages directly from the Linux kernel’s networking stack after decryption has occurred.

It then converts this data into standard IT traffic, enabling visibility into application-layer communications without requiring access to encryption keys.

By providing robust visibility into these cloud environments, KlearSight reportedly empowers organisations to better manage and optimise their infrastructure, ensuring more reliable and efficient operations.

“Enhancing AI-driven observability”

Jim Frey, Principal Analyst, Omdia stated: “Microservices running on a Kubernetes cluster generate multiple metrics, events, logs and traces to provide some visibility across complex multi-cloud environments.

“However, searching through telemetry data streams to determine the root cause of an incident can be like searching for multiple needles across multiple haystacks.

“The ultimate source of truth lies in packets and organisations can only benefit by establishing this level of visibility enterprise-wide, including the cloud and Kubernetes environments.

“Time and again, this has proven to be crucial for rapid recognition and diagnosis of performance incidents and issues while also enhancing AI-driven observability.”

Extending and enhancing observability

Developed from NETSCOUT’s expertise in network traffic analysis, Deep Packet Inspection (DPI) and real-time traffic intelligence, KlearSight reportedly uses extended Berkeley Packet Filter (eBPF) technology to extract packets from within the Linux kernel’s networking stack.

It is said to extend and enhance observability to understand system behaviour and accelerate troubleshooting and incident response with unprecedented, low-overhead access to granular system and application data.

The result is, according to the company, moving beyond monitoring what is happening in the environment towards understanding the why of any issue, including unusual patterns and anomalies, that often go unnoticed.

“Our solutions are mission-critical”

Phil Gray, AVP, Product Management, NETSCOUT commented: “NETSCOUT has been delivering innovative observability and visibility solutions that address end-through-end performance challenges for decades.

“Our solutions are mission-critical to large enterprises across all industries, especially as AI and cloud complexity continue to accelerate.”
