Hi everybody,
At this moment, I set up an steem node Linux server, I think I can contribute to it throught applications (It seems not so easy, but I keep going ).
I just want share a little trick, I use for years now, to read instantly a server load, that's useful when you have a lot of opened terminal for instance.
BEFORE
you have to check "top" instruction, you get
AFTER
Open a new session with Putty, you get the server load in the bar, refreshing every 2 seconds
So cool ! and easy !
To do this :
Put this PERL code to a new file called /home/steem/view_load
#!/usr/bin/perl -w
use strict;
$|++;
my $machine=`/bin/hostname`;
chomp $machine;
while (1) {
open (CHARGE,"/proc/loadavg") ||die "Unable to open /proc/loadavg: $!\n";
my @charge=split(/ /,<CHARGE>);
close (CHARGE);
print "\033]0;";
print "$machine -- load : $charge[0] $charge[1] $charge[2] at ", scalar(localtime);
print "\007";
sleep 2
}
Don't forget to put good executing right
chmod +x /home/steem/view_load
then add this line in the end of your .bash_profile (or create .bash_profile if it's not existing) /home/steem/.bash_profile (~/. bash_profile)
/home/steem/view_load &
And that's all !
You can customize and put other informations to display, but I prefer keeping simple "load + clock".
As terminal I use Putty, it works as a charm on CentOS and here on Ubuntu 16.04 LTS
See you next time
