--- title: "Monitor VPN Path Aryaka remote site TCP optimization" canonical: "https://docs.aryaka.com/space/KNOW/1544485/Monitor%20VPN%20Path%20Aryaka%20remote%20site%20TCP%20optimization" format: markdown --- The VPN Path Aryaka > TCP Optimization > Remote Site page is similar to the VPN Path Aryaka > TCP Optimization page except the remote page monitors the optimized traffic traveling between two specific sites' ANAPs and the other monitors all optimized traffic traveling in and out of the ANAP to anywhere else in the network. Like the VPN Path Aryaka > TCP Optimization page, the VPN Path Aryaka > TCP Optimization > Remote Site page contains graphs that display optimization statistics. However, the graphs plot the TCP optimized traffic and resulting benefits for two selected sites connected using the VPN Path Aryaka network. If it is not already open, open the VPN Path Aryaka > TCP Optimization > Remote Site page as follows: To open the VPN Path Aryaka Remote Site TCP Optimization page Log in to MyAryaka. The Home page appears. Click SD-WAN > Monitor in the left navigation pane. The Site: page appears. Click the Reference Site drop-down list and select one of the two sites between which you want to monitor VPN Path Aryaka optimization statistics. Click VPN Path Aryaka in the WAN Traffic by Network graph. The Network: VPN Path Aryaka page appears. The sites in your Aryaka network appear in a tree-map graph. Click the area of the second of the two sites whose VPN Path Aryaka optimization statistics you want to monitor. The Remote Site: page appears. Click the TCP Optimization icon in the navigation bar at the bottom of the page. The TCP Optimization page appears for the selected site and selected remote site. The components of the Remote Site > TCP Optimization page are described in the following sections. Apply filters The filter pane contain the following components that allow you to select the criteria that determines the graph details that appear on the page. Component Description Traffic Direction field Select one of the following options to determine the direction of the traffic flow for the selected site: Inbound Only—Graphs traffic received at the site. Outbound Only—Graphs traffic leaving the site. 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. The Last 24 Hours plots graph with traffic collected in the last 24 hours. Last Day plots the traffic during the last calendar day. Similarly, Last Month plots the traffic during the last calendar month, and so on. Current Month plots the traffic during the current calendar month. You can select a custom time, date, and year going as far back as five years. Apply button Saves and applies your filter selections to the page's graphs. Included graphs The following graphs appear on the VPN Path Aryaka > Remote Site > TCP Optimization page: Connections—Plots the number of connections for accelerated (optimized) and pass through (unprocessed) traffic. LAN Traffic by Optimization—Plots the optimized LAN traffic for the selected sites and time period. Perceived Network Latency—Measures and plots the elapsed time between a SYN request and SYN ACK when traffic is left in pass-through versus when it is accelerated by Aryaka. Similar round-trip time (RTT) is applicable for data in addition to the handshakes. Actual Network Latency—Measures and plots the ping latency between the two sites over VPN Path Aryaka and plots the latency of each of the network legs/segments (site to POP, POP to POP, POP to site).
