PHP problem

[bobobobo]

Hi!

So, I'm having some issues with the installation, even though thing are working more or less as expected. Here is how the log looks:

I am also getting holes in my graphs, like no data was getting in (see attached image).

There are also other errors in the log:

You are running a single cmd.php process. You need to increase that in the Data Collection section of Cacti.

i have since moved to spine, but the issue is still present...

[cigamit]

Have you increased the number of threads and processes for spine? If you are still running 1 / 1 you are still going to have this problem.

i had to experiment a bit, but it seems that i hit the nail on the head now - the graphs have been gap-free for the past few days. still getting the log message though...

[cigamit]

The log message actually has nothing to do with Cacti. Its a PHP Startup error telling you that you are trying to load the same PHP module twice. Probably either because you are loading in 2 different conf files.

is that a problem? how can i track it down?
