oops. need a new release for f. It's a simple fix. For every rrdtoo_* command, you need to place an "@" in front of it. Do that and test.

Thak you for reply.
I placed "@" sign before "rrdtool_function_create" function in file poller_rt.php but that does not work.

Code: Select all

                        /* create rt rrd */
                        if (!file_exists($rt_graph_path)) {
                                /* get the syntax */
                                $command = @rrdtool_function_create($item['local_data_id'], true, array());

                                /* replace path */
                                $command = str_replace($data_source_path, $rt_graph_path, $command);

                                /* replace step */
                                $command = preg_replace('/--step\s(\d+)/', '--step ' . $interval, $command);

                                /* WIN32: before sending this command off to rrdtool, get rid
                                of all of the '\' characters. Unix does not care; win32 does.
                                Also make sure to replace all of the fancy \'s at the end of the line,
                                but make sure not to get rid of the "\n"'s that are supposed to be
                                in there (text format) */
                                $command = str_replace("\\\n", " ", $command);

                                /* create the rrdfile */
                                shell_exec($command);
                        }

Could you please give me an example for correct syntax?

Yea, sorry. Can you pull the trunk version in about 15 minutes and test. Provide feedback. We'll be releasing a slue of plugins this week for compatibility.

I have found an error when i upgrade cacti 0.8.7e to 0.8.7f : the image doesn't load

Code: Select all

Fatal error: Cannot pass parameter 3 by reference in /var/www/cacti-0.8.7f/plugins/realtime/poller_rt.php on line 184

On the file poller_rt.php on line 184

Code: Select all

$command = rrdtool_function_create($item['local_data_id'], true,array());

Just replace "array()" by "$emptyvar"

Like that :

Code: Select all

$command = rrdtool_function_create($item['local_data_id'], true,$emptyvar);

And realtime load image correctly...

I think it's a problem with new RRDtool syntax.

Code: Select all

ERROR: I don't understand ':	0 bytes\n' in command: 'COMMENT:Total In:	0 bytes\n'.
ERROR: I don't understand ': to OSC West\n' in command: 'COMMENT:Description: to OSC West\n'.

Is there a way to fix that?

Hey guys,

Having the same issue, updated a few days back and didn't see any bug reports so thought it was me, but couldn't find a fix.

Anyway, glad I found this out now...

Where can I grab the latest version from?

Thanks,
Aaron.
