Hmm so I copied the folder to my home directory. After doing that the server began to slow way down and I eventually hard to hard restart it in Vcenter. Is back up now but still having same issues. Part of me is hesitant to delete said files as they have a lot of graph data built up.
On the bad side it seems like all graphing (Not just bandwidth) broke around 6:19PM Sunday. Do you still think I should delete all files in said folder and will I be able to get graphing data back from the backup files if this doesn't fix the problem?
For the graphs I do see, if I go back to last week I see all the graphing data. Of course most of the objects I have added since then do not actually have any graph at all.

Okay so now everything has graphs, but they are still empty.
Also I am seeing this now when I run
Code: Select all
sudo env LANG=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --debug="snpo,log" --logging $HOME/mrtg_troubleshooting.txt
Looking at one of my switches OID 675:
Code: Select all
2015-03-12 15:47:54 -- --log: RRDs::tune(/var/lib/mrtg/10.32.20.1_675.rrd -a ds0:125000000 -a ds1:125000000 -d ds0:COUNTER -d ds1:COUNTER)

FYI, I work with Benson and my post about MRTG is somewhat tied to this problem. I am effectively taking over for him in this regard.
Here is my thread:

Brief update. About an hour after aforementioned reboot all the graphs started working again, most of them not having any lost any data during the time the graphs were not working. I will post if it seems to break again. Is there any log I could get to you guys to see what exactly happened and why they work now?

Sorry for the long delay for this. Everything for the most part seems to be working now. If I have problems related to this again should I post in this thread or a new one?
