 Sorry for troubling you all.
Hi.

Oh and BTW you should NULL terminate your array.

So long,

Andreas.

[rrd-users] RRD File Not Being Created (linux, RRDTool 1-1.3.1, rrdlib, c++)

2008-07-29 Thread Robert Easton 

Hi,

When I call rrd_create in my program it returns 0 and there is no error set
(rrd_get_error()). Yet the rrd files are not created. I have checked folder
permissions and they are fine. I have run the rrdtool create command from
command line, using the same parameters and that works fine. 

Also, I had to move the DS parameter to the last position in the array. When
I had it before the RRA parameters rrd_get_error() returned that there was
not a data source declared. That is strange also.

So, why is my c++ app not creating any files and why did I have to move the
DS to the last array position? This code snippet shows what I am doing:

char start_time_s[50];
long start_time;
int ret;

start_time = (long)time (NULL);
sprintf (start_time_s, %ld, start_time);

char *opts[] = { _rrd_file_path, --start, start_time_s, --step, 
60, 
RRA:AVERAGE:0.5:1:10080, RRA:MIN:0.5:1:10080, 
RRA:MAX:0.5:1:10080, RRA:LAST:0.5:1:10800,
RRA:AVERAGE:0.5:60:4464, RRA:MIN:0.5:60:4464,
RRA:MAX:0.5:60:4464, RRA:LAST:0.5:60:4464, 
RRA:AVERAGE:0.5:1440:365, RRA:MIN:0.5:1440:365, 
RRA:MAX:0.5:1440:365, RRA:LAST:0.5:1440:365,
DS:sensor:GAUGE:120:U:U };
   
ret = rrd_create( 18, opts);
if (ret == -1)
stdout  rrd_get_error();

Cheers,
Mark

I fixed the problem. After looking at rrd_tool.c I realised that it was
including the first parameter of create.  So, I placed create in to the
first array position for opts and it worked.

Sorry for troubling you all.
