Spine 0.8.7a with cacti 0.8.7b problem

Post by johnzw »

I download spine 0.8.7a and install successful.
everything is good when cacti 0.8.7b use cmd.php to grasp snmp data.
However, when I changed the poller from cmd.php to spine, I got some messages in cacti log, as follows:
07/16/2008 10:35:01 AM - POLLER: Poller[0] Maximum runtime of 298 seconds exceeded. Exiting.

cacti can't call RRDs to draw graph, and I searched poller.php, I found the following codes, maybe useful:

Code: Select all

 /* end the process if the runtime exceeds MAX_POLLER_RUNTIME */ 
                                if (($poller_start + MAX_POLLER_RUNTIME) < time()) { 
                                        cacti_log("poller_start =" . $poller_start , "Maximum runtime of ". MAX_POLLER_RUNTIME , " time" . time() , true, "POLLER"); 
                                        rrd_close($rrdtool_pipe); 
                                        cacti_log("Maximum runtime of " . MAX_POLLER_RUNTIME . " seconds exceeded. Exiting.", true, "POLLER");
I add a debug cacti_log() line in the above code, and the log as follows:

I don't know the mean of $poller_start and time(), anyone can help me to explain it ? or give me a solution about this problem ? thank you very much.

my linux installed in Xen Server. Is this virtual-machine time problem ?
I know the time of virtual-machine has some problem, but I am not a expert. I running a ntp script on my virtual linux and sync with the ntp server (Xen system).
anyone can help me ? thank you.

Did you see the max runtimes show up right after you made a time change? also I think it you run the poller by hand outside of the regular polling cycle it will cause this error on the next poller run, but should be fine after that.

Hello,
I installed cacti on a Linux virtual machine and encountered time issues even with ntp installed (time would shift around 30s in a 1m period).

The solution was to change the way the VM handle time in the grub.conf.

hello grazog, I don't understand your mean, could you give me a example? how to modify grub.conf to corrective time.

I didn't made a time change, and my poller interval is 5 min. and I saw some information in the internet which told me time() has some trouble in virtual system and might be cause some problems.

What happens when you run spine manually? You can run "./spine -V 5" for more information.

I'm having the same problem with spine.... If I change the poller within cacti to spine it exceeds the 300 seconds and the log reports that 0 rrds processed...

If I run spine manually as you described, it completes in 19 seconds!!

Any clues?

Hello,
sorry for the delay i didn't saw your message.

Here is a link to the grub modification and an explanation of the time problem on VM :
