[rrd-users] Re: How can I change the length of the RRAs ?

[Stanley Hopcroft]

Dear Ladies and Gentlemen,

I beg your pardon for my careless about this.

However, for the benefit of the archives,

From: Tobias Oetiker <oetiker at ee.ethz.ch> 

well, how about this:

NOTES
     The new .rrd file, with the modified RRAm, is written to the
     file resize.rrd in the current directory.  The original .rrd
     file is not modified.


cheers

I thought the resize would be applied - yes, this was stupid - to the
original RRD, instead of a newly (prudently) created RRD named
'resize.rrd'.

Partly this was because my stable installation of rrdtool
(1.0.38) _lacks_ this very useful note.

'
       rows    the number of rows you want to add or remove.

NOTES
       It is possible to abuse this tool and get strange results by
       first removing some rows and then reinsert the same amount
       (effectively clearing them to be Unknown). You may thus end up
       with unknown data in one RRA while at the same timestamp this
       data is available in another RRA.

UNION SUNDOWN
(Words and Music by Bob Dylan)
1983 Special Rider Music

Well, my shoes, they come from Singapore,
My flashlight's from Taiwan,
My tablecloth's from Malaysia,
My belt buckle's from the Amazon.
You know, this shirt I wear comes from the Philippines
And the car I drive is a Chevrolet,
It was put together down in Argentina
By a guy makin' thirty cents a day.

Well, it's sundown on the union
And what's made in the U.S.A.
Sure was a good idea
'Til greed got in the way.

Well, this silk dress is from Hong Kong
And the pearls are from Japan.
Well, the dog collar's from India
And the flower pot's from Pakistan.
All the furniture, it says "Made in Brazil"
Where a woman, she slaved for sure
Bringin' home thirty cents a day to a family of twelve,
You know, that's a lot of money to her.

Well, it's sundown on the union
And what's made in the U.S.A.
Sure was a good idea
'Til greed got in the way.

Well, you know, lots of people complainin' that there is no work.
I say, "Why you say that for
When nothin' you got is U.S.-made?"
They don't make nothin' here no more,
You know, capitalism is above the law.
It say, "It don't count 'less it sells."
When it costs too much to build it at home
You just build it cheaper someplace else.

Well, it's sundown on the union
And what's made in the U.S.A.
Sure was a good idea
'Til greed got in the way.

Well, the job that you used to have,
They gave it to somebody down in El Salvador.
The unions are big business, friend,
And they're goin' out like a dinosaur.
They used to grow food in Kansas
Now they want to grow it on the moon and eat it raw.
I can see the day coming when even your home garden
Is gonna be against the law.

Well, it's sundown on the union
And what's made in the U.S.A.
Sure was a good idea
'Til greed got in the way.

Democracy don't rule the world,
You'd better get that in your head.
This world is ruled by violence
But I guess that's better left unsaid.
>From Broadway to the Milky Way,
That's a lot of territory indeed
And a man's gonna do what he has to do
When he's got a hungry mouth to feed.

Well, it's sundown on the union
And what's made in the U.S.A.
Sure was a good idea
'Til greed got in the way.
