Graphs not updating on first load with Boost plugin enabled

[mavink]

I'm trying to debug a really strange issue with the Boost plugin. My Cacti setup is:

- Debian linux, with the stock apache2 and php5 packages
- Cacti 0.8.7b
- Plugin Architecture 2.1
- Boost 2.1

The problem I have is that with the Boost plugin enabled, graphs don't display the first time you try to view them. The RRD-files that the graphs are based on are updated on disk, but you have to refresh the page to actually view the graphs.

Has anybody else seen this issue?

Apache needs r/w to the RRA directory. I general set the setgid bit on the directory and make it "cactiuser:apache".

Sorry, I forgot to mention that I've already tried that. Even with write access for every user it still doesn't work; the RRA files are updated correctly, so I think the write access is working.

Well for existing ones, but new ones is always the issue provide the following for me:

cd /var/www/html/cacti
ls -altr
cd rra
ls -altr

The index for the RRA directory is a bit long (about 6000 files), but all files are owned by www-data and are writeable by everyone. I see the files being updated when I try to view a graph, but the graph itself doens't show on the first try.

I tried using the update server, but that had the same results.

I would write a simple test script that attempt's to write an empty file into the rra directory and then attempt to execute it from the web site and see it that works. If not, it's a permissions issue. Also, if you are not using boost 2.0 or better, upgrade to the latest.
