Endpoint Agent: How it works

Lightweight client software Windows 7+, Mac OS X 10.9+

Negligible resource consumption Typically <1% CPU, <40MB mem, <50MB disk

Easy deployment via standard tools msi & pkg installers w/ auto-registration

End-user & background components Browser plugin (Chrome & IE) & system service

Always up-to-date Updates automatically, runs in the background

User Sessions - Web Completion, response time, page load waterfall

User Sessions - Network Loss, latency, jitter, failures, path visualization

Visibility across multiple layers Agent details

Access Network Topology Wired, wireless, VPN & proxy network topology

6

•  Infrastructure Mode: Wireless devices can communicate with each other and with a wired network

•  Wireless Access Point (AP): Connects wireless devices to a wired network

•  Basic Service Set (BSS): One AP and the set of wireless devices connected to it –  Identified by BSSID

•  Extended Service Set (ESS): Two or more interconnected BSSs that form a single network –  Identified by SSID

Wireless Network Building Blocks

7

Wireless Network Architecture

8

•  Routes traffic between internal devices and outside networks, joining two networks together –  NAT, DHCP, security, encryption

Gateways

9

•  Can have many functions: – Monitoring and surveillance –  Firewall and traffic filtering –  Traffic encryption and

decryption –  Network connection sharing –  Data caching –  Anonymity

•  Typically deployed: –  At the edge of a LAN •  Services users within the LAN,

including those using VPN to tunnel in

–  In the cloud •  Wider visibility and coverage for

all employees

•  Popular vendors include: –  Blue Coat, Cisco, Zscaler, F5

Proxies

10

Local Area Network (LAN)

11

•  Uncover aggregate trends •  Data collected every 5 minutes

– Metrics collected from OS: •  Link speed •  Wireless signal quality

– Metrics collected from network probes: •  Gateway, proxy and VPN loss and latency •  Delay and forwarding loss

•  Tip: Deploy an Enterprise Agent at the proxy location to monitor the path from proxy to destination

Network Topology View

12

•  Troubleshoot individual users’ issues •  Data collected every time user visits a monitored domain in

a monitored network – Web and network performance in addition to network topology
