The Ecessa appliance provides network statistics and graphs to display current and historic network activity. This article will describe how to view graphs, create custom graphs, and view network and system statistics.
In the web interface, click on View Statistics found in the top toolbar. The default tab will be Graphs:
The View Graphs section will display utilization data for WAN, LAN, Port, or Channel Bonding sites. The View Live Graphs link will begin a dynamic graph displaying the current utilization information while View Historical Graphs link will show a static graph displaying the utilization information for the specified time range. If no range is provided, the historical graph will display results for the past day by default.
Users can create custom graphs to display different types of data beyond bandwidth utilization. Some custom graphs may exist by default - such as CPU utilization, Memory utilization, Top IPs To, Top IPs From, Top Services, and Top Protocols. Please note: disabling session statistics will prevent certain graphs (the "Top" graphs, specifically) from displaying any data.
To view a user graph, click the View button.
User graphs can display data as a Line or Pie graph. Additionally, "events" will be noted in certain graphs which will provide further details when clicked on as shown below.
Clicking the Settings tab or the View Graph Statistics button will show what the current settings are for graphing and reporting. While the statistics settings may be altered on this page, the graph settings cannot. A new graph must be created if separate settings are desired.
To create a custom graph, click the Add button in the View User Graphs section to display the Add a new Graph/Chart form. Enter the appropriate information for the graph to create. Then click the Add button at the bottom of the Add a new Graph/Chart section.
The Report tab allows users to view multiple historical graphs at the same time. The graph types are pre-set but the time range can be adjusted as necessary. The selected graphs will be displayed on the lower portion of the page after clicking the Generate button as shown below.
The Network Statistics tab includes system, traffic information, network statistics, and WAN statistics. System statistics include uptime, temperature, CPU utilization, and memory utilization.
Traffic information includes current state and utilization of each WAN link while Network Statistics include total bytes and port errors. The presence of port errors usually indicate a port speed/duplex issue.
WAN Statistics include the number of current TCP and UDP sessions over each WAN link as well as the round trip time (RTT) for each test point. This information can be used to easily identify possible WAN line latency issue.
