Hi,
I installed rrdcleaner.
The plugin checks unused rrd files correctly.
But when I try to delete, I get this message:

aggregator_maltepe_traffic_in_816.rrd Error : unable to delete!

I think this is about permission problem.
How can I fix it?
Here is the permission of rrd file :

[root@citizen rra]# ls -la agg*816*
-rw-r--r-- 1 nobody nobody 945944 Mar 2 2006 aggregator_maltepe_traffic_in_816.rrd

And in crontab, poller.php runs with root user:

*/5 * * * * root /usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1

Is there any information needed to solve the problem?

Original Post :
-------------------------------------------------
I've installed the rrdcleaner plugin but i don't see anything new on my cacti ( 0.8.6i + plugin arch V1.1) but the Backup directory field in Console>Settings>Paths.

What do I have to do to see the rrdcleaner part ?
Do i have a permission problem ?
-------------------------------------------------


EDIT : Nevermind, forgot to put the access right (Realm Permissions) in user management ...

In case this helps anyone else:

I had the "Permission denied" unlink() error, but I just knew I had the permissions set right. Yet, I continued to have the error.

I discovered a comment on the unlink() page at php.net:
http://www.php.net/manual/en/function.unlink.php#59122

In it, one commenter says you must remember to set approprriate permissions on the folder as well. So for Cacti users, if you continue to have permission issues, make sure your web server user/group has write permissions on the 'rra' folder itself.

I hope I didn't miss this same issue earlier in this thread...

After I got this plugin installed, I was able to delete dozens of old rrd files. After that initial delete run, I noticed this plugin lists files that are being used (some, not all). I know this because after each run of poller.php, the file's last access time (in this list) is incremented by five minutes! And I checked the data sources for those file names and they are, in fact, being used. After browsing the graphs, I am seeing a lot of blank graphs (some, not all) and I have a feeling the previous delete action deleted some in-use rrd files.

Yes, the clock is correct on the Cacti PC.

At the very early days (before it became a plugin), I dealt "a bit" with it. So my knowledge is a bit old. But I'm quite sure, that there are circumstances, where this plugin fails; e.g. externally updated rrd files. Nevertheless, I do like it. But I would always pay attention to the last update timestamp (that's why I added it) and never delete files with recent update timestamps.

I meet an error like that:
Warning: Invalid argument supplied for foreach() in /var/www/html/cacti/plugins/rrdclean/rrdcleaner.php on line 38


But Gilles' patch can't be downloaded, who can give me a download link??

I too am having the issue where it lists some RRDs which are still being used (the timestap updates every 5 minutes). I think a good idea would be to add a feature so that you can "sort by" the columns (especially the Last Modified column) that way you can easily pick out the unused RRDs from the in use RRDs.

Please find the new version of RRDCleaner, V0.3, attached. From README:

----[ Purpose

    This plugin analyzes many cacti db structures
    to determine unused rrd files.

----[ Features

    1) allows for filtering and sorting on
       - rrd file name
       - date/timestamp of last rrd file modification
       - size
    2) file delete is done by the poller
       This avoids permission errors or security issues.
       The same instance that creates rrd files, the poller,
       will be used for deletion as well.

----[ Prerequisites

    Before you install RRDCleaner, you need to have met the following pre-requisites:

    1) Cacti 0.8.6j is fully supported along with plugin arch V1.1
    2) Other versions: on your own risk, but not yet tested

----[ Installation

    Install is similar to other plugins.
	Realm ID 36 is used. No sql import necessary

----[ Usage
