Ok, I've read the manpages on netstat and it gives a good description of the state values such as CLOSE_WAIT, ESTABLISHED, SYN_RECEIVED, etc..
Can someone give me real world situations where you would get these states. LIke for example if I got SYN_RECEIVED what possible situations would be the... (1 Reply)
One of my servers started getting heavily loaded a few weeks ago for a few hours, so I did some studying and wrote a script to use netstat to get the IP addresses connected and the count. I put a new chain in iptables and if an IP is using more than 40 connections, it gets added to that chain which... (3 Replies)

turbostat reports C-states of all CPU cores, and includes entries for each hyper-threaded core as well. Often enough the two logical cores on a single physical core will list different C state percentages. Does that make any sense?
Is this reporting the c-states of the few duplicated parts... (8 Replies)

Alzabo::ForeignKey(3pm) User Contributed Perl Documentation Alzabo::ForeignKey(3pm)NAME
Alzabo::ForeignKey - Foreign key (relation) objects
SYNOPSIS
use Alzabo::ForeignKey;
foreach my $fk ($table->foreign_keys)
{
print $fk->cardinality;
}
DESCRIPTION
A foreign key is an object defined by several properties. It represents a relationship from a column or columns in one table to a column
or columns in another table.
This relationship is defined by its cardinality (one to one, one to many, or many to one) and its dependencies (whether or not table X is
dependent on table Y, and vice versa).
Many to many relationships are not allowed. However, you may indicate such a relationship when using the Alzabo::Create::Schema->add_rela-
tion method method, and it will create the necessary intermediate linking table for you.
METHODS
table_from
table_to
Returns the relevant "Alzabo::Table" object.
columns_from
columns_to
Returns the relevant "Alzabo::Column" object(s) for the property as an array.
column_pairs
Returns an array of array references. The references are to two column array of "Alzabo::Column" objects. These two columns correspond in
the tables being linked together.
cardinality
Returns a two element array containing the two portions of the cardinality of the relationship. Each portion will be either '1' or 'n'.
from_is_dependent
to_is_dependent
Returns a boolean value indicating whether there is a dependency from one table to the other.
is_one_to_one
is_one_to_many
is_many_to_one
Returns a boolean value indicating what kind of relationship the object represents.
is_same_relationship_as ($fk)
Given a foreign key object, this returns true if the two objects represent the same relationship. However, the two objects may represent
the same relationship from different table's points of view.
id
Returns a string uniquely identifying the foreign key.
comment
Returns the comment associated with the foreign key object, if any.
