--- title: "Monitor ANAP system health" canonical: "https://docs.aryaka.com/space/KNOW/1611279/Monitor%20ANAP%20system%20health" format: markdown --- The ANAP System Health page displays two color-coded line graphs that display CPU and memory details for the selected site's active ANAP. You can apply a filter that determines the time period that is graphed. If it is not already open, open the ANAP System Health page as follows. To open the ANAP Traffic 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 ANAP you want to monitor. Click the ANAPs icon in the navigation bar at the bottom of the page. The ANAP Traffic page appears. Click the System Health icon in the ANAP Traffic page's navigation bar. The ANAP System Health page appears for the selected site. The components of the ANAP System 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 selected site's Active ANAP's System Health page displays two line graphs that plot ANAP health for the following ANAP components: CPU—Plots data points for the following categories: User—Plots the percentage of the ANAP's CPU processing power being used by user-space processes. Tasks processed by the CPU's user space include, but are not limited to, application-level processes of the selected ANAP. These are essentially all CPU processes performed by anything other than the kernel. Note that when a user-space process requires hardware access, a request is sent to the kernel, which is plotted as kernel processing. Kernel—Plots the percentage of the ANAP's CPU processing power being used by the kernel. Tasks processed by the CPU's kernel space include, but are not limited to, powering device drivers, some operating system processes, file system management, running the CPU scheduler, and so on. Kernel processes are also know as system processes . Idle—Plots the unused CPU processing power. Depending on the model of the ANAP and the number of CPUs available, this graph goes up as high as 800%. Memory—Plots data points for the following categories: Used—Plots the memory currently allocated to processes. Free—Plots the unused memory currently available.
