Monitor General Server / Desktop system health in
console on Linux
saidar is a text based ncurses program to display live
statistics about general system health.
It displays in one refreshable screen (similar to
top)
statistics about server state of:
CPU, Load, Memory, Swap, Network, I/O disk operations
Besides that
saidar supports a ncurses console colors, which
makes it more funny to look at.
Saidar extracts the statistics for system state based on
libgstrap cross platform statistics library about pc system
health.
On Debian, Ubuntu, Fedora, CentOS Linuxes saider is available for
install straight from distribution repositories.
On Debian and Ubuntu
saidar is installed with cmd:
debian:~# apt-get install saidar
...
On CentOS and Fedora
saidar is bundled as a part of
statgrab-tools rpm package.
Installing it on 64 bit CentOS with yum is with command:
[root@centos ~]# yum install
statgrab-tools.x86_64
Saidar is also available on FreeBSD as a part of the
/usr/ports/devel/libgstrab, hence to use on my FreeBSD I had
to install the
libgstrab port:
freebsd# cd /usr/ports/devel/libstatgrab
freebsd# make install clean
Here is
saidar running on my Desktop Debian on Thinkpad in color
output:
debian:~# saidar -c
I've seen many people, who use various shell scripts to output
system monitoring information, this scripts however are often
written to just run without efficiency in mind and they put some
let's say 1% extra load on the system CPU. This is not the case
with
saidar which is written in
C and hence the
program is optimized well for what it does.
