--- title: "Monitor VPN Path Aryaka remote site health" canonical: "https://docs.aryaka.com/space/KNOW/1642369/Monitor%20VPN%20Path%20Aryaka%20remote%20site%20health" format: markdown --- The VPN Path Aryaka Remote Site Health page is similar to the VPN Path Aryaka Health 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. The VPN Path Aryaka Remote Site Health page contains four line graphs that display ICMP and TCP statistics. The graphs plot the statistics for two selected sites connected by the VPN Aryaka network. If it is not already open, complete the following procedure to view the VPN Path Aryaka Remote Site Health page: To open the VPN Path Aryaka Remote Site Health 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 health statistics. Click VPN Path Aryaka in the WAN Traffic by Network bubble graph. The Network: VPN Path Aryaka page appears. Click the box of the second of the two sites whose VPN Path Aryaka health statistics you want to monitor in the Network Traffic by Remote Site treemap graph. The Remote Site: page appears. Click the Health icon in the navigation bar at the bottom of the page. The Health page appears for the selected site and selected remote site. The components of the Remote Site > Health 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 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 Health page: ICMP Latency—Measures and plots the internet control message protocol (ICMP) latency between the echo request and the echo reply for the two sites over VPN Path Aryaka. This end-to-end network path between the selected pairs of sites is represented using the three segments of the path: Site 1 to POP 1, POP 1 to POP 2, and POP 2 to Site 2. The latency for each segment is displayed. ICMP Loss—Measures and plots the number of packets lost during ICMP ping tests for the selected sites over their VPN Path Aryaka connection. TCP Health—Helps identify any abnormal network conditions (for example, a SYN flood attack) that can 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. Retransmissions—Plots the percentage of TCP traffic between the two sites that failed to arrive at its destination the first time and had to be retransmitted on the VPN Path Aryaka network.
