Select Status from the menu bar at the top of the screen.
The following links will appear in a submenu on the left side of the screen. They give detailed status information about various aspects of your Endian Firewall:
Each link will be explained individually in the following sections.
Select Status from the menu bar at the top of the screen, then select System status from the submenu on the left side of the screen.
This screen is divided into the following sections (accessible via tabs or scrolling):
| Services | - | lists the status of all the services installed on Endian Firewall - a service might appear as STOPPED simply because the corresponding feature is not enabled. |
| Memory | - | this is the output of the Linux free command. The first
bar shows the total used memory: it is normal for this value to be close to 100% for a
long running system, since the Linux kernel uses all available RAM as disk cache.
The second bar shows the memory actually used by processes: ideally this should be
below 80% to keep some memory available for disk caching - if this value approaches
100%, the system will slow down because active processes are swapped to disk:
you should consider upgrading RAM then. The third bar indicates the swap usage,
for a long running system it is normal to see moderate swap usage (below, say, 20%),
especially if not all the services are used at all time. |
| Disk usage | - | this is the output of the Linux df command. Shown is the used disk space
for each disk partition (/, /boot and /var for a
default install). / and /boot should be rather constant,
/var grows while using the system. |
| Uptime and users | - | this is the output of the Linux w command that reports the current time,
information about how long your system has been running without a reboot, the number
of shell users that are currently logged into the system (normally there shouldn't be
any) and the system load average for the past 1, 5 and 15 minutes. Additionally, if
any shell user is logged into the system, some information about the user is displayed
(such as the remote host from which he or she is logged in). |
| Loaded modules | - | this is the output of the Linux lsmod command, that shows the loaded kernel modules
(the information is of interest to advanced users only). |
| Kernel version | - | this is the output of the Linux uname -r command, that shows the current kernel
version. |
