Hi,
which handy Linux command line tools you know to give admin good image on data traffic size currently going on on the server?
i found "iftop" which is available in EPEL (redhat) i think, so installable via yum install iftop . It shows connections and amount of transfered data.
Next very handy tool i found nload (Network Load)
165
(the graph is sliding to the left in realtime, one can use arrows to browse other network interfaces beside eth0)
nload install:
Installing nload network datatransfer monitor with realtime graphs in/out data on Redhat CentOS 5.11 64bit ! (other Linux will work too probably)
cd /usr/src;wget http://downloads.sourceforge.net/project/nload/nload/0.7.2/nload-0.7.2.tar.gz
tar zxvf nload-0.7.2.tar.gz;rm -rf nload-0.7.2.tar.gz;cd nload-0.7.2
./configure
if found error "configure: error: C++ compiler cannot create executables", then do: yum install gc gcc++ *gcc-c++*
try again:
./configure
if found error "ncurses library or development files not found.", then i fixed by installing ncurses development pack:
yum install ncurses-devel
try again:
./configure
if no error:
make && make install
