(Resolved) Realtime Showing Broken Images

[TheWitness]

Yea, IIS is a bit of a mess and that's where your problem lies. BSOD2600 can provide more information on IIS. I have not used it since 2005. I use Apache whether or not it's a Windows box or a Linux/UNIX box.

I've really got tired of this, so I completed disabled II6 and Install Apache...(Never used it before!)... Once I've got the Server up , changed a few things in Cacti and voila!....

everything works like charm, cacti and plugins.......

realtime never worked under IIS, now now is runing perfectly...

PHP Fatal error: Cannot pass parameter 3 by reference in cacti/plugins/realtime/poller_rt.php on line 188
ERROR: I don't understand ':

I'm getting errors about line 188 in the script no mater what changes i do.

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

You need to move to the latest stable, which does not work on PRE 0.8.7f.

I'm having the same problem... I have the latest Realtime04.3 , PA2.9 Cacti0.8.7 .

Sometimes it works but most of the time it's not. I don't know if its related with my current server load:

top - 16:59:48 up 9 days, 1:48, 6 users, load average: 7.97, 10.37, 11.98

HTTPD log:

I have other server running the same setup but less server load and realtime plugins works consistent.

I there a way to optimized my config?


Tnx,

Use rrdtool 1.2.x to reduce load, or optimize the fccache while using 1.3/1.4. Otherwise rrdtool 1.3/1.4 will crush your system.

tnx for that tip. I've tried that fc-cache and it improves cacti graph rendering, but the root cause of the error was not the server load, it was the php-gd that i used to install last week. Just discovered last night that it's not just realtime plugins that was affected. I'm posting it to a new thread under Weathermap.
