Issues with polling and display of graphs...

[prateek2385]

Hi,

I am a Cacti newbie. I have installed Cacti-0.8.8a on a Win7 machine. I have been following all the steps for installation and configuration as per the Cacti manual and have been able to install everything correctly.
However, I am facing issues trying to plot my first graph. No data points appear in my graph and I get the following error all the time. I am not able to proceed any further.

Also, when i run poller.php from command line, i get:
Waiting on 1 of 1 pollers.

Kindly advise.

Thanks and regards,

Please increase logging level.
I assume, that you're using a script that does not return valid values within time
R.

Hi.
Thanks for responding. Attached is the cacti log file for your reference. Please let me know if any other details are required.

Here is a sample as well:

check the cacti task. Are there two instances? It configured to run every 5 minutes?

Using any 3rd party scripts/templates?

[prateek2385]

Hi,

I have scheduled only 1 task in task scheduler and I am running the poller every 5 mins. Also, i am not using any 3rd party scripts. Just trying to implement from the Cacti manual - Chapter 4, page 9.
Please refer the attached screenshots and provide any pointers.

Thanks and regards,

Did you actually check the Windows Task scheduler? That's what fires off poller.php and starts the polling processes. The poller setting screen only tells Cacti how your system is configured.

Your graph errors should be troubleshooted by reading through http://forums.cacti.net/viewtopic.php?f=3&t=11747

Hi,

I have scheduled poller.php from windows task scheduler itself. Also, all installations were done referring to Cacti manual.

* I am currently using Cacti 0.8.8a. Is there a patch available on this version also ?
* Another point is that the machine i am using is a virtual machine. I read in one of the blogs that we face issues on VMs. Is that the case?
* Also, please guide me on how to generate various RRD files. I was able to generate one RRD file bu running poller.php. but it does not get updated from the scheduled task. Also, I added other graphs and they appear as broken images as required RRD files are not present. But, i am not sure what script to run to generate the required RRDs.

Appreciate if someone can guide.

Thanks and regards,
Prateek

Only one listed at http://www.cacti.net/download_patches.php

Not for small installations.

Cacti creates the rrd files, you should not be manually doing so. The fact files were generated when you manually ran poller.php, but not when the scheduled task does, is typically a sign NTFS permissions are not properly configured. See http://docs.cacti.net/manual:087:1_inst ... e_security
