wavemon
wavemon
is a ncurses-based monitoring application for wireless network devices. It
plots levels in real-time as well as showing wireless and network related device
information.
The
wavemon
interface splits into different "screens". Each screen presents
information in a specific manner. For example, the "info" screen shows current levels
as bargraphs, whereas the "level" screen represents the same levels as a moving
histogram.
On startup, you'll see (depending on configuration) one of the different monitor
screens. At the bottom, you'll find a
menu-bar
listing the screens and their activating
keys. Each screen is activated by either the corresponding function key or the key
corresponding to the first character of the screen name. The following screens can be
selected:
Info (F1 or 'i')
This is the most comprehensive screen. It displays a condensed overview of
wireless-specific parameters and network statistics, as well as bar graphs. The
layout is arranged into several sub-sections.
The
Interface
section at the top shows information about the monitoring
interface, including interface name, type, ESSID, and available encryption
formats.
Below, in the
Levels
section, you can see up to four bargraphs showing (1)
relative signal quality and (2) signal level in dBm. If the wireless driver also
supports noise level information, additionally (3) noise level in dBm and (4)
Signal-Noise-Ratio (SNR) in dB are shown. The colour of the signal level
bargraph changes from red to yellow and green at fixed levels. If thresholds
have been set, two arrows on the signal level graph will show the positions of
the current thresholds.
The
Statistics
section displays packet and byte counters and a few other
packet-related statistics.
The subsequent
Info
subsection lists the current operational mode and
configuration of the wireless interface. What parameters are actually shown
depends on the capabilities and selected mode of your network device.
