This morning at about 5AM my Cacti installation stopped drawing all graphs. I have attached an example from one graph, but all graphs across all devices show the exact same behavior at the same timestamp.
I am running Cacti 0.8.6j and have been using it successfully for several weeks now until this. I can't point to anything as having changed on my Cacti server to suddenly cause this (nobody from my office is even awake at 5AM
).I have verified that the MySQL server is running, accepting connections, and has the correct privileges for my cacti user account.
I have verified that the correct user has access to rra/ in my Cacti directory.
There are no errors or warnings listed in my Cacti logs even with the log level set to DEBUG.
I can run the poller manually with no problem. In fact, I'm pretty sure that Cacti is polling correctly and returning accurate values. As shown in the attached image, the legend is reporting values for load and they match what I get from logging in to the monitored server and running top.
What can I do to troubleshoot this further? Any help or suggestions will be much appreciated.
