Overview

The Application View tab and Network View tab provide charted summaries of performance. Both tabs display the 10 Top Flows — a subset of the Monitoring menu’s Current Flows.

Additionally, the Monitoring menu provides a variety of reports:

n	Viewing Charts

These charts feature pan and zoom capability for bandwidth, reduction, packets per second, flow counts, latency, loss, and out-of-order packets. You can review data from the last 30 days.

n	Viewing Application Statistics

These summarize each application by percentage of total LAN traffic, reduction percent, and inbound and outbound bytes.

n	Viewing Current Flows

You can view a listing of existing connections, based on selectable filter criteria. Additionally, you can customize which data columns display and view a flow’s details.

n	Viewing Realtime Charts

You can select a filter and a metric to plot any of six types of realtime stats, and you can plot more than one chart at a time. The charts update every 3 seconds.

n	Viewing QoS Statistics

You can view the total number of bytes and packets transmitted and received, based on traffic class and/or WAN QoS [DSCP markings].

QoS statistics display the data accumulated since the last reboot. You can also non-destructively clear the counters to zero and view the delta values.

n	Viewing Tunnel Statistics

Tunnel statistics specify the number of bytes and/or packets received, processed, and transmitted by a tunnel in both the outbound (LAN-to-WAN) and inbound (WAN-to-LAN) directions. They tally control packets, as well as accelerated versus non-accelerated traffic flow, round-trip latency, and packet loss before and after forward error correction.

Tunnel statistics display the data accumulated since the last reboot. You can also non-destructively clear the counters to zero and view the delta values.

n	Viewing Flow Redirection Statistics

This shows the statistics collected, specific to the process when you allow two (or more) appliances to exchange flow ownership information and then redirect packets to the owner.

n	Viewing NetFlow Statistics

This displays how many NetFlow statistics the appliance exported to the collector(s). Stats are defined in terms of number of flows, and number of datagrams (packets) required to export those flows.

n	Viewing Interface Statistics

Interface statistics display generic performance data for the actual physical LAN, WAN, and management interfaces (primary and secondary).

Interface statistics display the data accumulated since the last reboot. You can also non-destructively clear the counters to zero and view the delta values.

n	Viewing Bridge Mode Statistics

This summarizes the data traffic traversing all the LAN and WAN interfaces, in a redundant bridge mode deployment.

n	Viewing Next-hop Reachability

This page displays the state of each management, WAN, and LAN next-hop.

Before discussing individual reports, the next section describes the basics of viewing reports.
