Analyze

• Performance Analyzer provides real-time and trended

monitoring of tenants, hosts, VMs, fabrics, and ports, as well as

high-frequency monitoring that gathers valuable performance

data for tracking queue depth and heat-map visualization.

Network Director analyzes the entire network, using heat-

maps to identify over- and under-utilized ports, latency, and

top VMs, users, devices, and ports.

• Network Traffic Analyzer proactively monitors network usage

to find the sources of network traffic spikes. Incorporating an

automated policy-driven sFlow collector and flow analysis,

Network Traffic Analyzer quickly identifies and isolates users,

applications and protocols consuming the most bandwidth.

• Flow Path Analyzer provides operational and diagnostic

capabilities that trace connectivity between applications and

flows by correlating network telemetry data with the

application. Flow Path Analyzer visualizes network paths

between leaf and spine switches for a given flow/application,

correlating congested ports with high-latency events and

identifying impacted or unhealthy VMs, applications, and

hosts.

• Overlay and Underlay Analyzer provides full visibility,

performance management, and troubleshooting capabilities for

physical and virtualized overlay networks in VMware Virtual

Extensible LAN (VXLAN) and controller-less environments. It

provides a consolidated and correlated view of VMs, hosts,

fabrics, and overlay and underlay networks with full end-to-

end network and flow visibility and analysis.

• VM Analyzer provides real-time physical and virtual topology

views, tracks vMotion activity including virtual machine

creation, deletion, and moves, and maintains complete virtual

network inventory.

• Fabric Analyzer monitors and analyzes the health of the entire

network fabric, including IP Fabric, Virtual Chassis Fabric

configurations, and Juniper Networks QFabric® System,

increasing service availability.

Features and Benefits

End-to-End Network Visibility and Flow Path Analysis

Working in conjunction with the Cloud Analytics Engine, Network

Director provides network data analysis to improve application

performance and availability by associating flows with specific

applications across the physical and virtual infrastructure, improving

the ability to quickly roll out new applications and troubleshoot

problems (see Figure 1).

Network Director analyzes and visualizes application flows running

on VMs and bare-metal servers in the data center, reporting the

specific path a flow takes through the network, the latency

encountered at each hop, and traffic statistics for every network

device in the path. Users can start flow analysis on selected active

flows on a specific VM or a non-virtualized host on demand and

view the results. When users place a critical VM or non-virtualized

host on a watch list, Network Director will automatically initiate

analysis on all flows running on that device.

Network Traffic Analyzer

The Network Director Network Traffic Analyzer gathers detailed

information about network bandwidth usage patterns on each

switch port, allowing network administrators to make informed

policy and planning decisions about specific applications and ports.

Using an automated, policy-driven sFlow collector and flow

analysis, Network Traffic Analyzer identifies which users,

applications and protocols are consuming the most bandwidth,

helping network administrators identify the source of network

spikes and bursts to proactively monitor, control and manage

network usage (Figure 2).
