Set the poll interval to 10 seconds to get realtime graphs

[PPRRBBDD]

Hi my cacti's friends.

I've been looking, in the web and at this forum, how to get graphs in real time(at least 10 seconds, I already have 1 minute graphs)? In other words, how to run the poller interval every 10 secs? (Scheduled task from windows can't do it) Do I have to modify the poller.php file some how too? Is there a script that I can run for windows to get this 10 seconds poll interval, wich one? Please help me, I'm desperate. Has anyone done this before? Is there another way?

Operating System: Windows XP SP3
Webserver: Apache 2.2
Cacti: 0.87e
Spine: I'm using cmd.php
MySQL: 5.0
PHP: 5
RRDTool (Cygwin or Win32 version): Win35 1.2.30.0
Net-SNMP: 5.5
Cygwin (cygwin1.dll version):
Plugin Architecture: 2.5
Hope someone knows the answer
Best Regards.

The realtime plugin will poll as fast as 5seconds but it is for display it does not log.

Thanks Lazybones. Do you know how it works in windows?. I install and enable the plugin but I don't know where to see the graphs in real time.

I almost got it. I guess. I see the realtime button in the graphs. But I get this error. "The image cache directory directory does not exist. Please create it and then set permissions and the attempt to open another realtime graph" How can I do this? for Windows plase help

I am also running it under windows..

You have to go under Settings and the Misc Tab... there is a section for the Realtime plugin, you have to set a path for Cache Directory... Just go make a folder and then put that path there so it has a place to save files.

On my system I just used C:\Apache2\htdocs\cacti\plugins\realtime\cache but I actually had to make the folder "cache" in the realtime folder it will not create for you.. I am just running small config so I do not know what the impact of this folder is for performance..

I got it. But it seems that doesn't work at all, well, for me. It polls at 5 seconds but, the values are wrong, for example, in the graph with 1 minute interval the inbound traffic , is 4.75 kb(average). And in the real time graph it is showing 300Mb(every 5 seconds I'm getting values around 300Mb ). Also in the graphs that I create after running the realtime plugin, it displays wrong values too. Any idea to correct this issue?
