Memory graph
This graph shows the memory usage during the last 24 hours. The following colours are used to denote the types of
memory:
▪ Green - unallocated memory, that can be allocated to new processes.
▪ Blue - cache memory, copy of recent data used by processes.
▪ Orange - buffer memory, a temporary portion of memory that stores data to be sent to -or received from- external
devices.
▪ Red - used memory.
Swap graph
The usage of the swap area, located on the hard disk, is displayed in this box.
▪ Green - unallocated swap.
▪ Blue - cached swap.
▪ Red - swap space used.
Disk usage graphs
Graphs showing the usage of the disk are split into four boxes, each showing the usage of a partition. In each of them,
the green colour shows the free space, while the red colour shows the disk space used.
The four boxes show the free and allocated space in the four hard disk’s partitions: Main disk, configuration disk, log
disk, and data disk. For each of them, those colours are used.
▪ Green - space available.
▪ Red - space used.
In older 2.5 appliances, the disk graph was slightly different, since the data shown was not the disk usage, but the hard
disk accesses, denoted by two colours:
▪ Blue is used to show sectors read per second on the hard disk.
▪ Green is used to show the sectors written per second on disk.
2.4 Traffic graphs
This page contains the traffic graphs for the last 24 hours, divided by zone. Hence, depending on the zones enabled
and configured, this page will contain 2, 3, or 4 boxes, each with one graphs. Like the System graphs, the graphs are
accompanied with a legend of the data displayed:
▪ Green - the outgoing traffic.
▪ Blue - the incoming traffic
Below the graphs, also the summary of the average, maximum, and current amount of data transmitted and received
is displayed and updated in real time.
When clicking on one of the graphs, a new page will open, with summaries of the data flown through the IFA 3610/
IFA 2610/IFA 1610 appliances for the last day, week, month, and year. The data shown are the same in all the graphs:
Incoming and outgoing traffic in blue and green respectively. In
