Hi again,
I've gathered some more data on the apparent limitations of aggregate
traffic graphing, but am still stuck as to what the cause is.
first, I added some additional debug statements to the
api.rrdtool.inc.php script. the pertinant lines are:
in function rrdtool:
---snip---
//debug($command);
debug("Use pipe: ".$use_pipe);
debug($method." '".$file."' ".$aux);
if ($use_pipe)
list ($ret1, $ret2) = rrd_pipe($method." '".$file."' ".$aux);
else
exec($command,$ret1,$ret2);
debug($ret1);
debug($ret2);
---snip---
and down in function rrd_pipe:
---snip---
$numbytes = fwrite($GLOBALS["rrd_pipe"]["pipe"][0], $command."\n");
debug("length of command to write: ".strlen($command."\n"));
debug("wrote ".$numbytes." bytes to the pipe");
---snip---
As you'll see in the error in the output below (ERROR: RPN final stack
size != 1), I suspected that perhaps the command being piped to
rrdtool was being truncated. As you can see from the fwrite return,
however, the entire string appears at least to be successfully written
to the pipe. Is there a way to try the pipe command by hand?
If I run the $command from debug($command); from the shell it works
(it's too large to paste directly to the cli, so I have to put it in a
.sh to execute).
Here is the last two debug outputs of an aggregate graph (sorry for
the large email!).
