I want to create
separate column for CPU utilization % is that possible take out from
trend or other method.
Thanks,

Hi,
I use a personal
script to do that:
--- cut here ---
#!/usr/bin/perl
# written by
JC Simonetti
# version: 1.0, 2014-07-19
use warnings;
use strict;
use
Hobbit;
use SNMP;
if (! -x '/usr/bin/vmstat') {
exit 0;
}
if (! -x
'/usr/bin/tail') {
exit 0;
}
my $bb = new Hobbit('cpuUsage');
$bb->print("CPU Usage:nn");
#my @output = `/usr/bin/vmstat 1
2|/usr/bin/tail -1 2>&1` or die;
#foreach my $line (@output) {
# if (
$line =~
/d+s+d+s+d+s+d+s+d+s+d+s+d+s+d+s+d+s+d+s+d+s+d+s+d+s+d+s+(d+s+)d+s+/ )
{
# my $idle = defined($1)?$1:-1;
# my $color = "green";
# if ($idle <
30) {
# $color="yellow";
# }
# if ($idle < 10) {
# $color = "red";
# }
#
my $used = 100-$idle . " %";
# $bb->color_line($color, $used);
# }
#}
my $session = new SNMP::Session(
DestHost => "127.0.0.1",
Community
=> "netcomm",
Version => "2"
);
my $vb = new
SNMP::Varbind(["UCD-SNMP-MIB::ssCpuIdle", 0]);
my $var =
$session->get($vb);
my $output;
my $idle = -1;
if ($var =~
/NOSUCHINSTANCE/) {
$var = -1;
}
if ($session->{ErrorNum}) {
$output =
$session->{ErrorStr};
} else {
$idle = $var;
$output = 100-$var . "
%";
}
my $color = "green";
if ($idle < 30) {
$color = "yellow";
}
if
($idle < 10) {
$color = "red";
}
$bb->color_line($color, $output);
$bb->send;

You'll see I use 2 methods to get back
the CPU Usage: either by the system "vmstat" command (commented out in
my script) or by SNMP (don't forget to adapt your "community").
The
script is called "/etc/hobbit/ext/cpuUsage", and there's also a config
file "/etc/hobbit/clientlaunch.d/cpuUsage" that contains:
--- cut here
---
[cpuUsage]
#DISABLED
ENVFILE /etc/hobbit/hobbitclient.cfg
CMD
/etc/hobbit/ext/cpuUsage
LOGFILE /var/log/hobbit/hobbitclient.log
INTERVAL 1m
--- cut here ---
This configuration will create a
"cpuUsage" column with the percentage. The color values are for the
moment hardcoded in the script: less than 30% free is yellow, less than
10% free is red. Adapt them if you want :)
My script is quite basic
and all error use cases are not covered :)
Sincerely.
