Hi folks,
I have been struggling with rrd.h and rrdlib.a for awhile. I hope some of you
can shed some lights....
I am using a C program to create a bunch of ???.rrd file. I copied the
CountArgs() and CreateArgs() function from rrd_tool.c to my program so I can
create a array of string from something like
"create blah1.rrd -b N -s 300 DS:ds:GAUGE:6000:0:100 RRA:AVERAGE:0.5:1:288"
This string is used as the 2nd argument for CreateArgs(). I used a loop to
create blah1.rrd blah2.rrd ... blahx.rrd with the same parameters. However, as
I execute my program. Something funny happen.....the program successfully
generated the blah1.rrd, but it didn't generate another other blah?.rrd.
Instant it also generated a second file named "300". I think create_rrd()
picked up the "300" from the -s flag. BTW, rrd_create did not complain about
bad arguments.
The following is my code segment......
sprintf(createStr, "%s ./%s.rrd %s %s %s", string1, ds->filename, string2,
block, string3);
printf("%s\n", createStr);
int argc = 0;
char **myargv = NULL;
if ((argc = CountArgs(createStr)) == 0) {
perror("Insufficient arguments\n");
exit(-1);
}
if ((myargv = (char **) malloc ((argc+1) * sizeof(char *))) == NULL) {
perror("malloc failed\n");
exit (-1);
}
argc = CreateArgs("blah", createStr, argc, myargv);
if (argc <=0) {
printf ("Honston, we have a problem.\n");
exit;
}
-awk
-awk
