I'm a newbie to shell scripting, I was given this script to modify. This script that monitors when CPU Usage is too high based off the top command. The comparison is not working as it should. Its comparing a decimal to a regualar interger. When it send me an email, it send an email and ignores the if statement. I receive an email if its below or above 90. I only need an email if its greater than 90. I use
to run CPU up to 100%. and then test running the below script. Can you all please assist me in what I'm doing incorrectly here:
how can I find cpu usage memory usage swap usage and
I want to know CPU usage above X% and contiue Y times and memory usage above X % and contiue Y times
my final destination is monitor process
logical volume usage above X % and number of Logical voluage above
can I not to... (3 Replies)

email::send::test
Email::Send::Test(3pm) User Contributed Perl Documentation Email::Send::Test(3pm)NAME
Email::Send::Test - Captures emails sent via Email::Send for testing
SYNOPSIS
# Load as normal
use Email::Send;
use Email::Send::Test;
# Always clear the email trap before each test to prevent unexpected
# results, and thus spurious test results.
Email::Send::Test->clear;
### BEGIN YOUR CODE TO BE TESTED (example follows)
my $sender = Email::Send->new({ mailer => 'Test' });
$sender->send( $message );
### END YOUR CODE TO BE TESTED
# Check that the number and type (and content) of mails
# matched what you expect.
my @emails = Email::Send::Test->emails;
is( scalar(@emails), 1, 'Sent 1 email' );
isa_ok( $emails[0], 'Email::MIME' ); # Email::Simple subclasses pass through
DESCRIPTION
Email::Send::Test is a driver for use in testing applications that use Email::Send to send email.
To be able to use it in testing, you will need some sort of configuration mechanism to specify the delivery method to be used, or some
other way that in your testing scripts you can convince your code to use "Test" as the mailer, rather than "Sendmail" or another real
mailer.
How does it Work
Email::Send::Test is a trap for emails. When an email is sent, it adds the emails to an internal array without doing anything at all to
them, and returns success to the caller.
If your application sends one email, there will be one in the trap. If you send 20, there will be 20, and so on.
A typical test will involve doing running some code that should result in an email being sent, and then checking in the trap to see if the
code did actually send out the email.
If you want you can get the emails out the trap and examine them. If you only care that something got sent you can simply clear the trap
and move on to your next test.
The Email Trap
The email trap is a simple array fills with whatever is sent.
When you send an email, it is pushed onto the end of the array. You can access the array directly if you wish, or use the methods provided.
METHODS
send $message
As for every other Email::Send mailer, "send" takes the message to be sent.
However, in our case there are no arguments of any value to us, and so they are ignored.
It is worth nothing that we do NOTHING to check or alter the email. For example, if we are passed "undef" it ends up as is in the trap. In
this manner, you can see exactly what was sent without any possible tampering on the part of the testing mailer.
Of course, this doesn't prevent any tampering by Email::Send itself :)
Always returns true.
emails
The "emails" method is the preferred and recommended method of getting access to the email trap.
In list context, returns the content of the trap array as a list.
In scalar context, returns the number of items in the trap.
clear
The "clear" method resets the trap, emptying it.
It is recommended you always clear the trap before each test to ensure any existing emails are removed and don't create a spurious test
result.
Always returns true.
deliveries
This method returns a list of arrayrefs, one for each call to "send" that has been made. Each arrayref is in the form:
[ $mailer, $email, @rest ]
The first element is the invocant on which "send" was called. The second is the email that was given to "send". The third is the rest of
the arguments given to "send".
