More Information

Post by lorell »

I turned on Graphing Debug Mode.

Here is more information:

RRDTool Says:

ERROR: opening '/var/www/html/cacti/rra/pix_snmp_oid_46.rrd': No such file or directory

There is a /var/www/html/cacti/rra directory but it has nothing in it. I have chmod'ed that directory to 775 and have insured that cactiuser is the owner and apache is the group.

There are no files in the rra directory.

I went through these procedures to test my installation and I get a graph out of it.

http://www.cacti.net/downloads/docs/htm ... graph.html

That seems to work. No data in the graph yet, but the graph is there.

It did not create anything in the /var/www/html/cacti/rra directory, but I don't know that it was supposed to.

I understand that Cacti is a GUI front-end for RRDTool. But what is the source of these missing *.rrd files?

I think that these are supposed to be generated by Cacti when I add the device and choose what my data sources are supposed to be. Did I skip a step?

Debug for one of the data sources:

When I ran the following as root, rrdtool created the file as such:
/usr/bin/rrdtool create \

When I run it as cactiuser, I get a permission denied error as such:

I executed this:
chmod +s /usr/bin/rrdtool
But that has not helped the other graphs show up. THey still get the permissions in the debug graph menu.

What is going on here?

Thanks!

Please open a shell window, change to the cacti directory and run "php poller.php" and post your results.

1) Please apply patches from the following location: http://www.cacti.net/downloads/patches/ ... re-patched

2) Please select the correct version of RRDtool from Settings->General.

3) Rerun the "php poller.php" when you other poller (cron) is not.

4) Post results.

Thanks.

The graphs are all generated now. There is now data in them, so one of the following is at play:

1. Data sources are not properly configured.
2. More time needs to elapse and the data collection process will occur naturally.
3. Some thing else that I do not yet know.

Could be your cron is failing. Redirect output to a file and review it's contents. It could also be a permissions issue.
