DTrace is a comprehensive dynamic tracing framework created by Sun Microsystems for troubleshooting kernel and application problems on production systems in real time. Originally developed for Solaris, it has since been released under the free Common Development and Distribution License (CDDL) and has been ported to several other Unix-like systems.
DTrace can be used to get a global overview of a running system, such as the amount of memory, CPU time, filesystem and network resources used by the active processes. It can also provide much more fine-grained information, such as a log of the arguments with which a specific function is being called, or a list of the processes accessing a specific file.
As of October 2011, Oracle announced the porting of DTrace from Solaris to Linux, but as of October 13, 2014 it remains officially unavailable. An unofficial DTrace port to Linux is available, although with no changes in licensing terms. As an alternative, Linux's SystemTap provides a similar set of features as DTrace.
War in the living room,
We swore we weren't like that.
Once we went down that road,
There was no turning back.
Anger and jealousy
And distorted fact,
Left this pale shadow
of a life we once had.
How could you love and then
Change just like that?
You give your whole heart away
Then take it all back.
This is the end of the line tonight
We can't defend what we know ain't right.
It's over, it's over, it's over,
This love we should let die.
This is the end of the line.
Broken down promises
Linger on in my head.
The scars and the blemishes
that time could not mend.
How can you live losing
All we once had?
Come on now, little girl,
It ain't quite that bad.
This is the end the line Tonight
We can't defend what
we know ain't right
It's over, it's over, it's over
This love we should let die.
This is the end of the line.
Nothing but love gets you
so hypnotized.
Nothing but love brings
them tears to your eyes.
Nothing but love takes
away all your pride.
Nothing but love eats
You away inside.
This is the end of the line Tonight.
We can't defend what we know ain't right.
Two worlds amend, oh ya and
Two worlds collide.
It's over, it's over, it's Over
This love we should let die.
It's been coming for some time.
So goodnight and goodbye.
This is the end
This is the end
