Not creating a simple ping graph

[j0hnd03]

Hi,

I am trying to get Cacti to graph the latency of a host, but no graph gets created. I am getting the following error on graph debug mode:

"ERROR: opening '/var/www/html/rra/******_ping_185.rrd': No such file or directory"

I get the following in the Cacti log:

"CMDPHP: Poller[0] Host[6] DS[185] CMD: /usr/bin/perl /var/www/html/scripts/ping.pl ***.**.***.***, output: 3.41

"CMDPHP: Poller[0] ASSERT: 'U<' failed. Recaching host '***.**.***.***', data query #6 "

I have a different host with the same setup and it graphs fine.

Folder Permissions:
drwsr-sr-t 2 apache apache 4096 Nov 15 01:00 rra

Please help Cacti Gurus.

The assert issue is not related to the other one. Please see 2nd link of my sig for more debugging help

1. Check Cacti Log File

Please see my previous post for the errors in my log file.

2. Check Basic Data Gathering:

This works fine. I get the correct result.

3. Check cacti's poller:

php -q cmd.php <id> <id>

Returns nothing.


4. Check MySQL updating

Everything looks OK.


5. Check rrd file updating

There is no rrd file.

6. Check rrd file ownership

There is no rrd file.

7. Check rrd file numbers

There is no rrd file.

8. Check rrdtool graph statement

There is no rrd file.

9. Miscellaneous

Up to current cacti 0.8.6h, table poller_output may increase beyond reasonable size.

Still doesn't work.

10. RPM Installation?

Installed using the CactiEZ CD.

12. Not NaN, but 0 (zero) values?

Not Nans, not zeros. No graph or RRD file.

Any other suggestions?
