Viewing Appliance Statistics

Charts feature spark lines, as well as selectable (and modifiable) time ranges.

The following charts exist for monitoring appliances:

n	Health Dashboard

n	Appliance Data Transfer & Reduction

n	Appliance Max Bandwidth

n	Appliance Bandwidth Utilization

n	Appliance Bandwidth Trends

n	Appliance Bandwidth Cost Savings

n	Appliance Flow Count

n	Appliance Packet Count

These items are also grouped with appliance statistics in the Monitoring menu:

•	The Flows tables is discussed in more detail, separately, in “Viewing Flows”.

•	Alarms are addressed in “Alarms.”

Health Dashboard

Monitoring > [Appliances] Health Dashboard

The Health Dashboard provides provides a high-level view of your network's health, based on the filter thresholds you configure.

n	Filters are available for packet loss, latency, and jitter. For each, you can configure two thresholds. You can also filter for various levels of alarms.

n	Each block represents one hour and uses color coding to display the most severe event among the selected filters. Clicking a block displays a pop-up with specifics about that event, what value triggered it, and any additional threshold breach for that appliance during the same hour.

•	Green = normal operation

•	Orange = marginal

•	Red = needs immediate attention

•	Aqua = warning (an alarm level)

•	Grey = no data available

n	Threshold settings apply globally. They are not retroactive; in other words, setting new thresholds does not redisplay historical data based on newly edited values.

n	Deleting an appliance deletes its data.

n	If you are using overlays...

•	You can view each overlay's health individually.

•	If you remove an individual overlay, its individual data is not recoverable. However, its historical data remains included in All Overlays.

n	To access threshold configuration, click the gear icon ().

Appliance Data Transfer & Reduction

Monitoring > [Appliances] Data Transfer & Reduction

The Appliance Data Transfer & Reduction chart lists the top appliances based on the total volume of inbound and outbound traffic before reduction. It shows how many bytes the Silver Peak appliance saved when transferring data, aggregated over a selectable time period.

Appliance Max Bandwidth

Monitoring > [Appliances] Max Bandwidth

The Appliance Max Bandwidth chart lists the top appliances by the peak throughput (in either direction), within a selected time period. It compares the system bandwidth of the appliance to the effective bandwidth it's providing.

Appliance Bandwidth Utilization

Monitoring > [Appliances] Bandwidth Utilization

The Appliance Bandwidth Utilization chart lists the top appliances by the average percent of available bandwidth used. This helps you see if an appliance that is optimizing traffic is reaching its capacity.

To see if your data link is nearing capacity, refer to the Tunnel Bandwidth Utilization chart.

Appliance Bandwidth Trends

Monitoring > [Appliances] Bandwidth Trends

The Appliance Bandwidth Trends chart shows bandwidth usage over time.

Appliance Bandwidth Cost Savings

Monitoring > [Appliances] Bandwidth Cost Savings

The Bandwidth Cost Savings chart shows how much money and time the Silver Peak appliances could have saved based on reduced bandwidth usage. The monthly figures are calculated by extrapolating the savings from the selected time range.

To view or edit the various data link costs, click Configure Cost.

Calculations

n	For the monthly cost savings, it subtracts the maximum bytes you could send without the appliance from how many bytes the Silver Peak actually sent, and multiplies the difference by the data link cost.

n	For the monthly time savings, it uses the data link speed to calculate how many more hours it would have taken to send those additional bytes without the Silver Peak appliance.

Appliance Flow Count

Monitoring > [Appliances] Flow Count

The Appliance Flow Count chart lists the top appliances according to which ones had the most flows within a selected time period.

When you filter on All Traffic, the Created and Deleted columns display the number of new and ended flows for that same time period. The Max column value is from a one-minute window within the time range.

Appliance Packet Count

Monitoring > [Appliances] Packet Count

The Appliance Packet Count chart lists the top appliances according to the sum of the inbound and outbound LAN packets, showing how much traffic was sent.
