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

Thanks, Eli

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;

--- cut here ---

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.
