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

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.
