RRD Tool cannot find .rrd Graph after I add it.

I have added a Cisco 7206 router into devices and it appears to be working correctly. I click on Create Graphs for this host.
I select the interface to create the graph for and click on create. It returns with:
+ Created graph: Gateway 1 (Computer Solutions) - Traffic - Se3/0/7:3

Then I go to Graph Management and select the graph I create. The RRD Tool debug tells me>

ERROR: opening '/var/www/html/cacti/rra/gateway_1_computer_solutions_traffic_in_20.rrd': No such file or directory

No files are being created and placed in this directory. Any help would be much appreciated...

Thanks

The RRD file does not get created until the poller runs.

Thanks for the reply. I am obviously very new to Cacti. How do I get the Poller to run? Is there a setting that I need to change? It ran all night and still no rrd file was created so I am assuming I have something setup wrong.

Thanks

Thank you very much for your support. All appears to be working well with the exception of a few graphs. Some graphs seem to be updating consistantly, but a few of them are not showing any traffic at all. One graph worked for 1 5 minute duration then stopped working right after that. Any ideas?

Here is the output of a poller.php in debug mode:

You need to apply the patches in the following location:

Should resolve your problem.

Thanks a lot for these patches. This seems to be helping. I am still seeing a few graphs that are accumulating data intermittently. Here is the first part of the poller.php output:

I started fresh with new devices and graphs. Here is the output of my poller.php:

All seems OK, but the graph's are not accumulating data. I can create a graph, run the poller and view the graph, but It does not show any activity. I have installed these patches.

Thanks for all your help.

Verify that you only have 1 poller process in your CRON.

This is what I have in the crontab:

SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
HOME=/

# run-parts
01 * * * * root run-parts /etc/cron.hourly
02 4 * * * root run-parts /etc/cron.daily
22 4 * * 0 root run-parts /etc/cron.weekly
42 4 1 * * root run-parts /etc/cron.monthly
*/5 * * * * admin php /var/www/html/cacti/poller.php > /dev/null 2>&1

I pasted this in from the documentation. I am running on RH9.

Thanks again!

Research the RRDTool documentation. There is an RRD function called dump. Please look into your RRD file for data. Run in LOW for a few hours and recheck.

I changed the crontab to look like the following:

SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
HOME=/

# run-parts
01 * * * * root run-parts /etc/cron.hourly
02 4 * * * root run-parts /etc/cron.daily
22 4 * * 0 root run-parts /etc/cron.weekly
42 4 1 * * root run-parts /etc/cron.monthly
*/5 * * * * root php /var/www/html/cacti/poller.php > /dev/null 2>&1

I changed it from admin to root.

This appears to have fixed the issue and I am not sure why.

Thanks for all of your help in guiding me through this. If you have any more suggestions on this, please let me know.

Thanks again!
