To change the graph, click in the breadcrumb bar to display the graph settings panel.
The graph settings panel is hidden by default but this behavior can be changed. Navigate to System > General Setup and check Monitoring Settings to always display the settings panel by default.
The options on the settings panel are:
- Left Axis / Right Axis
The options here control the data dispayed on each axis. By default only the Left Axis is populated with a value, but both may be utilized to compare areas. First pick a Category (or None), then pick a Graph inside that category. The list of available categories and graphs will vary depending on the firewall configuration.
The general area of the desired graph: System, Traffic, Packets, Quality, Captive Portal, NTP, Queues, QueueDrops, DHCP, Cellular, Wireless, and VPN Users. These are covered in more detail later in this section.
The specific graph to display from the chosen category.
This section of the settings panel controls how the graph itself looks, including the time span and style.
- Time Period
The length of time to show on the graph. The default ranges cover from 1 hour up to 4 years, or a Custom period may be chosen. Selecting Custom displays the Custom Period controls. All of the periods are displayed even if there is no data in a graph database going back that far. The graph will be empty for times when graphing was not active.
The smallest slice of time for which data is available on this graph. Over time, data is consolodated over longer periods so resolution is lost. For example, on a 1-hour graph it is possible to see data from one minute intervals, but on a graph including older data, it is not possible to show data that accurately since it has been averaged out. Depending on the time period of the graph it may contain 1 Minute, 5 Minute, 1 Hour, or 1 Day averages for data. Resolutions which are not possible for the given time period cannot be selected.
Used on graphs such as the traffic graph, to separate incoming and outgoing data. For example, with Inverse set to On, outbound data is represented as a negative value to more easily differentiate it from inbound data.
- Custom Period
When Time Period is set to Custom, the GUI displays this section to configure the custom time period for the graph.
- Start Date
The start date for the graph. Clicking in the field will show a calendar date picking control. Only today, or days in the past, may be selected.
- Start Hour
The hour of the day to start the graph using 24-hour style (
- End Date
The end date for the graph.
- End Hour
The end hour for the graph, exclusive. The chosen hour is not included in the graph. For example, on a graph starting at hour
12, the graph covers 10:00am to 12:00pm.
Click Show Advanced to display additional advanced controls not typically required for average use.
- Export as CSV
Click this button to download the data from the graph as a
.csv(Comma Separated Values) spreadsheet file, which can then be imported into another program for analysis.
- Save as Defaults
Click this button to store the current graph settings as the default configuration so this specific graph will be displayed by default on future visits to this page.
- Disable/Enable Graphing
This toggle will disable or enable the collection of graph data. Graphing is enabled by default. Normally this would only be disabled for diagnostic purposes or if all required graphing is handled externally.
- Reset Graphing Data
Clicking this button will erase all graph database files and create new, empty files.
Click Update Graphs to change the graph to the selected view.
