--- title: "Monitor VPN Path Aryaka TCP optimization" canonical: "https://docs.aryaka.com/space/KNOW/1512379/Monitor%20VPN%20Path%20Aryaka%20TCP%20optimization" format: markdown --- The VPN Path Aryaka > TCP Optimization page contains three graphs that display various TCP optimization statistics including the number of connections and traffic for a selected site. If it is not already open, open the VPN Path Aryaka > TCP Optimization page as follows: To open the VPN Path Aryaka > 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 the site whose VPN Path Aryaka TCP optimization you want to monitor. Click VPN Path Aryaka in the WAN Traffic by Network graph. The Network: VPN Path Aryaka 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. The components of the 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 > TCP Optimization page: Connections—Plots the number of connections for accelerated (optimized) and pass through (unprocessed) traffic. LAN Traffic by Optimization—Plots the LAN equivalent of the traffic that was sent over VPN Path Aryaka. This traffic may have been accelerated by Aryaka or sent pass-through. The Peak Data graph is shown if you choose to view a time range that is longer than a day. POP Connection Setup Latency—Plots the time (in milliseconds) taken to set up a connection to the POP.
