<pre wrap="">All,
I am writing a function in PHP that opens a bi-directional process to
rrdtool using the syntax:
rrdtool -
As everyone is pretty much aware, this open a pipe that can receive
commands from standard in and echo back on standard out.
However, I wanted to confirm what character steam should be used to
confirm that an entire package has been received from the rrdtool pipe.
At the moment, I am using either of the following two substring matches:
"OK"
"ERROR"
Is this sufficient? Are there any other substring matches that tell me
that the command has completed?

almost, but have a look at the graphv command since it can return
an inline graph, there you have to just read the number of
characters advised before the graph is being dumped ...

This is fine. Except that the process is only doing the two calls:<br>
<br>
info<br>
xport<br>
<br>
for a statistical reporting interface. It's what essentially amounts
to last average and last peak from the RRD for each DS.<br>
