Tunnel Data Transfer & Reduction
Monitoring > [Tunnels] Data Transfer & Reduction
The Tunnel Data Transfer & Reduction chart shows which tunnels are sending the most bytes -- that is, the tunnels that are the most active.
Tunnel Bandwidth Trends
Monitoring > [Tunnels] Bandwidth Trends
The Tunnel Bandwidth Trends chart shows chart shows tunnel bandwidth usage over time.
Tunnel Max Bandwidth
Monitoring > [Tunnels] Max Bandwidth
The Tunnel Max Bandwidth chart lists the top tunnels by the peak throughput (in either direction), within a selected time period. It shows how quickly data could have been sent through the tunnel.
Tunnel Bandwidth Utilization
Monitoring > [Tunnels] Bandwidth Utilization
The Tunnel Bandwidth Utilization chart lists the top tunnels by the average percent of available bandwidth used. This helps you see if a data link is reaching its capacity.
To see if your appliance is nearing capacity, refer to the Appliance Bandwidth Utilization chart.
Latency
Monitoring > [Tunnels] Latency
The Latency chart shows which tunnels have the most transmission delay, generally as a result of congestion.
Latency Trends
Monitoring > [Tunnels] Latency Trends
The Latency Trends chart shows tunnel latency over time.
Loss
Monitoring > [Tunnels] Loss
The Loss chart shows which tunnels have the most dropped packets.
Loss Trends
Monitoring > [Tunnels] Loss Trends
The Loss Trends chart shows tunnel packet loss over time, before and after Forward Error Correction (FEC).
Out of Order Packets
Monitoring > [Tunnels] Out of Order Packets
The Max Out of Order Packets chart shows which tunnels receive the most packets out of sequence relative to how they were sent.
Out of Order Packets Trends
Monitoring > [Tunnels] Out of Order Packets Trends
The Out of Order Packets Trends chart shows tunnel packets out of order over time, before and after Packet Order Correction (POC).
Tunnel Flow Count
Monitoring > [Tunnels] Flow Count
The Tunnel Flow Count chart lists the tunnels with the most flows, on average. It differentiates flows into TCP (accelerated and unaccelerated) and non-TCP, and also shows peak values.
Tunnel Packet Count
Monitoring > [Tunnels] Packet Count
The Tunnel Packet Count chart shows which tunnels sent the most packets.
Tunnels Summary
Monitoring > Tunnels Summary
The Tunnels Summary summarizes tunnel statistics — including reduction, throughput, latency, and packet loss.
