By the end of this article you’ll understand what GigaVUE-FM is, how it works, what benefits it delivers, how to deploy it, and key use-cases for network operations (NetOps), security operations (SecOps) and cloud operations (CloudOps).
What is GigaVUE FM?
GigaVUE FM is the centralized orchestration and management platform for the Gigamon Deep Observability Pipeline. In plain terms, it provides a single pane of glass to manage, visualize and control the traffic-visibility infrastructure across physical, virtual and cloud networks.
Here are the main characteristics:
-
It supports physical visibility nodes (e.g., GigaVUE G-Series, TA-Series, HC-Series).
-
It supports virtual visibility nodes (GigaVUE VM) in cloud or virtualized environments.
-
It offers REST APIs, automation via Ansible and programmability to integrate with broader toolsets and workflows.
-
It can be deployed as hardware appliance or software-only virtual appliance depending on scale and environment.
In short: if you have a complex network with multiple locations, cloud zones, virtual machines, and need to ensure you’re seeing, filtering and directing the right traffic to the right tools (security, analytics, performance), GigaVUE FM acts as the brain of the visibility fabric.
Why Does the Visibility Fabric Matter?
Before diving further into GigaVUE-FM, let’s clarify why a visibility fabric is so important.
Modern networks are far more complex than they used to be. You have:
-
On-premises data centers with physical servers and switches
-
Virtualized workloads (VMs) within those data centers
-
Public and private cloud workloads, containers, microservices
-
Remote offices, branch sites, remote employees
-
A wide range of security and performance tools (IDS/IPS, SIEM, APM tools, analytics platforms)
In this environment, blind spots become a serious risk: traffic that is encrypted, traffic that bypasses traditional taps, traffic between cloud workloads. Without a visibility fabric, you might miss malicious lateral movement, encrypted traffic, east-west flows, or simply overload your tools with irrelevant data.
GigaVUE and GigaVUE FM help solve this by:
-
Aggregating, filtering, transforming and forwarding traffic (using Flow Mapping and GigaSMART) so that tools receive only the relevant traffic.
-
Providing centralized management so you can reason about the fabric as a whole instead of discrete nodes.
-
Supporting encryption/decryption, cloud visibility, multi-site deployments.
Thus a visibility fabric is a foundational component of observability, security posture, and performance monitoring.
Key Features & Benefits of GigaVUE FM
Let’s explore the standout features of GigaVUE FM and how they translate into business/technical benefits.
Centralised Management & Control
One of the core features is centralized configuration, monitoring and control of all visibility nodes (physical, virtual, cloud).
Benefits:
-
Reduced operational complexity: you don’t need to individually configure hundreds of nodes.
-
Consistency: policies, flows, maps are managed uniformly.
-
Scalability: a single instance can support ~1,000 nodes; in high-availability mode up to ~3,000 nodes.
Programmable APIs / Automation
GigaVUE FM supports REST APIs, integration with Ansible and toolchains.
Benefits:
-
Infrastructure as code / policy as code: automate deployment and changes.
-
Faster response: e.g., trigger flow-map changes in response to threat detection.
-
Integration: tie visibility fabric into your orchestration, monitoring and CMDB systems.
Visibility Fabric Insights & Topology
The platform provides dashboards, end-to-end fabric topology views, audit logs, usage analytics.
Benefits:
-
Easily identify hot-spots, mis-configurations, under-utilised traffic.
-
Forensics and audit: track changes, map traffic usage over time.
-
Better capacity planning and tool placement.
Hybrid & Multi-Cloud Support
GigaVUE FM works across on-prem, private cloud, public cloud, remote sites.
Benefits:
-
Visibility extends beyond traditional data-center boundaries.
-
Supports modern architectures: VPCs, cloud workloads, virtual machines.
-
Future-proofing: as you evolve into cloud, visibility fabric stays consistent.
High Scalability & Resilience
Supports large scale deployments, hardware or software, high-availability clusters.
Benefits:
-
Ensures visibility infrastructure itself does not become the bottleneck.
-
Redundancy and high availability reduce risk of losing visibility.
Typical Use-Cases
Here are some concrete use-cases where GigaVUE FM adds tangible value.
1. Security Operations (SecOps)
In a large enterprise, SecOps teams need to detect and respond to threats rapidly. With GigaVUE FM:
-
They can ensure that all relevant network traffic — including encrypted traffic that is decrypted, east-west flows, cloud traffic — is sent to security tools.
-
They can automate redirection of flows in response to an alert (e.g., send specific traffic to packet capture, bypass or isolate).
-
They gain topology visibility to understand where blind-spots exist.
2. Network Operations (NetOps)
Network teams want to monitor performance, troubleshoot issues, understand flows. With GigaVUE FM:
-
They can view traffic maps, identify oversubscribed links, optimize utilization.
-
They can filter and forward traffic to performance tools selectively.
-
They can schedule firmware or policy roll-outs across many nodes simultaneously.
3. Cloud & Hybrid-Cloud Operations (CloudOps)
In modern infrastructures with public and private cloud, CloudOps teams need unified visibility. With GigaVUE FM:
-
They can discover virtual traffic nodes, integrate with cloud workloads.
-
They can manage visibility across cloud and on-prem from one interface.
-
They can apply consistent traffic policies across hybrid environments.
Deployment Considerations & Best Practices
When integrating GigaVUE FM into your environment, you’ll want to follow best practices:
-
Sizing & Hardware/Software Choice: Decide whether you’ll run as hardware appliance or virtual machine. Hardware may be preferable for large scale. Ensure you meet minimum requirements: e.g., for virtual install: 16 GB memory, 2 vCPU, 80 GB storage.
-
Integration Planning: Define your visibility fabric architecture—where are the nodes, what are the flows, which tools are attached.
-
Policy Design: Define your Flow Mapping® and GigaSMART® policies with care so that only relevant traffic is forwarded to tools—this reduces tool overload and cost.
-
Automation & Version Control: Use the REST APIs to automate changes, track policy versions, and align with your infrastructure as code practices.
Challenges & How GigaVUE FM Helps Mitigate Them
Modern networks bring specific visibility challenges; GigaVUE FM addresses many of them:
-
Blind spots in cloud & hybrid environments: Many tools focus only on on-prem or perimeter traffic. With GigaVUE FM you have unified visibility across clouds.
-
Tool overload / irrelevant traffic: Without filtering and mapping, tools receive too much noise. GigaVUE’s Flow Mapping and smart forwarding mitigate this.
-
Complexity of managing many nodes: Visibility fabric often spans hundreds of nodes and sites. Centralised management simplifies this.
-
Need for agility: Threats and network changes are frequent. GigaVUE FM’s APIs and automation let you respond faster.
-
Encrypted traffic and east-west flows: Visibility fabrics that can handle decryption, internal flows and cloud traffic are crucial; GigaVUE supports these.
Conclusion
In an era where networks span data centers, public clouds, private clouds and remote sites—and where security threats, compliance requirements and performance demands grow daily—the need for comprehensive visibility is non-negotiable.
The GigaVUE FM fabric manager from Gigamon offers a highly capable solution for centralised orchestration of the visibility fabric, enabling network, security and cloud operations teams to gain control, scale visibility and optimise tool usage. From centralized dashboards to programmable APIs, from Flow mapping to hybrid-cloud coverage, GigaVUE FM is positioned to support the modern infrastructure.
