Display Load
Display Load shows statistics on the traffic load to and from the firewall's interfaces. This feature is available for all models except Ingate Firewall 1200.
Once every minute the load on all interfaces is scanned and saved to a local file. Every file contains 240 samples and a file generation consists of 42 files. The first generation of files contains samples for the last week (approximately). Every new file generation is created by merging two consecutive samples, enabling the storing of samples for the double time period in the same disk space. Merging the samples include calculation of the minimum, average and maximum values for the time interval covered by the samples. After ten generations (about 19 years) the samples are deleted.
Time period
Select a time period or enter a period of your own choice in the bottom fields. The date is written as a year with two or four digits, month (01-12) and day (01-31). The optional punctuation between year, month and day must be dash (-). Time is written as two digits for the hour, two digits for the minute and possibly two digits for the second, although the seconds can be left out. The optional punctuation between hours, minutes and seconds must be colon (:) or period (.).
Interface
You can select one or more of the firewall's interfaces or the total traffic. Selecting more than one interface will generate one graph per interface. You can also select to view only VPN traffic.
Direction
Select one or more of Sent, Received and Sent+Received. Each selection generates a separate graph in the diagram.
Value
Select maximum, average or minimum value of each sample period. If viewing load for time periods within the last week, all three selections will result in the same graph.
Unit
Select between displaying packets/second or bits/second. The graphs may look different, because all packets aren't the same size.
At the bottom, customize the diagram look. You can enter a diagram heading (optional) and the size and maximum values of the diagram. If the maximum values fields are left blank, the diagram axes will be automatically scaled to fit the graphs.
View diagram
Creates a diagram at the top of the page.
For each combination of selections, a graph will be generated. Example: You selected eth0 and Total as interfaces, and Sent, Received and Sent+Received as directions. This will generate a total of six graphs of different colours in the diagram.
