Overview of Analyzing Traffic with the Priority Analyzer
The Priority Analyzer page lets you analyze QoS and Policy Based Routing (PBR) data, and can present you with a better understanding of how the network bandwidth for a site is used and routed. Based on your analysis, you can then make changes to the Bandwidth Management profiles and PBR configuration.
Where applicable the data is shown for each separate WAN link.
To show the analytics for site QoS and traffic priority:
From the navigation menu, click Network > Sites and select the site.
From the navigation menu, click Site Monitoring > Priority Analyzer.
To filter for a specific Class of Traffic, in Search enter the string.
The Priority Analyzer page updates and only shows Priorities that match the search string.
This example and the table that follows explain the fields in the Priority Analyzer for the Bandwidth Management Profiles:
Name | Description |
|---|---|
Bucket Granularity | The amount of time that is represented in each bucket |
Priority | The Bandwidth Management Profile from Network > Bandwidth Management |
Used In | Name of network rule where this Bandwidth Management Profile is used |
Usage & Health |
|
Throughput | The average throughput for the time frame (upstream and downstream) |
Discarded Packets | The average percentage of packets discarded by the QoS engine (upstream and downstream) |
Delay | The average traffic delay caused by the QoS engine (upstream and downstream) |
Drilling Down to Bandwidth Management Profile Data
You can expand a row for a specific Bandwidth Management Profile to drill-down and show the traffic data for that profile.
To drill down to a Bandwidth Management Profile:
From the navigation menu, click Network > Sites and select the site.
From the navigation menu, click Site Monitoring > Priority Analyzer
In the Priority Analyzer screen, click the expand button
for the Bandwidth Management Profile and the row expands.To show the data for the bucket duration, hover the mouse on one of the graphs.
To hide the QoS graphs, click the hide button
for the Bandwidth Management Profile and the row closes.
The following example shows the additional traffic data for a profile:
Use the mouse to hover over on a graph and select a bucket. The following traffic data is shown for the bucket:
Overview - (not shown in the screenshot) throughput, discarded packets, and packet delay
Throughput - graph showing the throughput data
Packets Delay - graph showing the packet delay in milliseconds
Top Hosts shows the specific hosts with the highest usage for this profile
Top Apps shows the specific applications with the highest usage for this profile
Discarded Packets - graph showing the number of discarded packets
Note:
The graphs in the Priority Analyzer page show discarded packets for each QoS profile. The Discarded graphs in the Tunnel section of the Network Analytics page show the aggregated discarded-packet percentage for each tunnel, without a breakdown by QoS profile. If the discarded-packet percentage is less than 0.1%, Network Analytics shows 0.0%. Therefore, Priority Analyzer can show discarded packets for a QoS profile while Network Analytics shows 0.0%.
