[rrd-users] ANNOUNCE: dsreport 1.22

2001-03-15 Thread steve rader 

A new dsreport can be found at [1].  This version correctly
reports NaN values (which were previously reported as being
zero.)  

(My thanks to Mark Mills <[EMAIL PROTECTED]> for pointing
out my silly perl coding error that caused the problem.)

Well thats it. I thought rrd.h did this. 
It seems that today is my brain-damage day... ;-)
Nevertheless many thanks. Now it works.

I think you should include stdio.h from your program.

[rrd-users] Storing integer values in RRD?

2001-03-15 Thread Anders Ringaby 


Hello everybody!

Is there anyone who knows what kind of data
that can be stored in a RRD database? The
manual talks about numerical values, but I
suspect they always mean alphanumerical
characters. As an example, if you want to
store the value 99 in RRD, you store the
string "99".

But in this case, I would like to store integer
VALUES in a RRD database, as integers, and I
would like rrdtool to interpret them correctly,
and to show them in a graph correctly.

The reason for this is that I have wrote
a C program that reads unsigned 32 and
64 bit integers from a socket, and I would
like to store them in their original form
in RRD, without having to convert them
to strings first ( WITHOUT having to run
fprintf(..,"%d") or sprintf(..,"%d") ).

Can this be done? If so, how?

Regards

Anders Ringaby

[rrd-users] Accessing a rrd-database using C?

2001-03-15 Thread Andreas Maus 

Hi!

I want to update my RRDs using C.
So I guess, I have to includ rrd.h and link the program against the
librrd. Right?
But if I try to compile the program gcc says:
[EMAIL PROTECTED]:~/code/c/rrd:gcc -o rrdtest -L/usr/local/rrdtool/lib
-I/usr/local/rrdtool/include rrdtest.c -lrrd

 /usr/local/rrdtool/include/rrd.h:60: parse error before `*'

Hmmm...Whats the problem?
Line 60 in rrd.h is:

int  LockRRD(FILE *);

So this shouldn't be a problem...
The problem I try to compile (rrdtest.c) is:

#include "rrd.h"

int main (int argc,char** argv)
{
  int i=rrd_update(argc,argv);
  return 0;
}

(Yeah, I know it is silly, but its just a test.)

Is there anyone out there who can give me a hint how to get rid of this
problem?

Thanks in advance...Andreas.

Thanks at all,

I've done it using ths following process:

[rrd-users] update_RRD

2001-03-15 Thread Radek Machan 

I want to use my C program (demon) to update several RRDs every
second. How to do it? I can't call external program rrdtool update. Is
there any library to use directly in C? I can't find any solution and
examples in manual.

[rrd-users] Changing an RRA CF after creation of an RRA

2001-03-15 Thread Freddy Frouin 

Hi,

I would like to know if it is possible to alter the Consolidated
Function (CF) of an RRA after the Round Robin Database has been
created.

For exemple: How can I migrate a RRA:LAST:0.5:1:2880 to
RRA:MAX:0.5:2880 ?

Thanks in advance,  Freddy.
