Component Description Time field Determines the period for which to monitor and graph the traffic for the selected reference site. Each time period has an associated data interval defined for it. For example, if you select the Last 24 Hours time period, the associated data interval is 30 Minutes, which means a sample is taken and graphed every 30 minutes for a 24 hour period. Select one of the following time period/data interval pairs to graph the selected site's traffic: Last 1 Hour (1 minute) Last 4 Hours (1 minute) Last 8 Hours (1 minute) Last 24 Hours (1 minute) Last 7 Days (30 minutes) Last 30 days (30 minutes) Last Day (1 minute) Last Week (30 minutes) Last Month (30 minutes) Current Month (30 minutes) Custom (varies per custom time period defined) Note: Last Day is different from Last 24 Hours.

Included graphs The following graphs appear on the VPN Path Aryaka > Health page: Site to POP Ping Latency—Plots the time (in milliseconds) of the ping initiated by the selected site's ANAP to reach the POP to which it connects. Site to POP Ping Loss—Plots the ping loss percentage on the VPN Path Aryaka network between the selected site's ANAP and the POP to which it connects. Site to POP DPD Loss—Plots dead peer detection (DPD) loss as a percentage of the traffic on the VPN Path Aryaka network between the selected site's ANAP and the POP to which it connects. Network Health—Plots the percentage of TCP traffic that failed to arrive at its destination the first time and had to be retransmitted on the VPN Aryaka network. Packet Loss—Plots the percentage of the packet loss during a ping from the POP to which the selected site's ANAP is connected for the VPN Path Aryaka network at the selected site. TCP Health—Displays SYN packet statistics on VPN Path Aryaka, which helps the user identify any abnormal network conditions (for example, a SYN flood attack), which might impact the performance or availability of an application. SYN—Indicates the total number of TCP connections attempted per time delta. SYN with no traffic—Indicates the total number of connections that timed out before being established. SYN-RST—Indicates the total number of connections that were not established due to a reset sent by the server.
