Our Observium professional server file system was recently damaged beyond recovery. Fortunately the database and the Observium directory had been backed up the night before.
The older server OS was CentOS 6 and the new OS is CentOS 7 (both 64 bit).
The Observium directory was restored and the database imported; now the Observium web page is working well, with visibility of all devices, historic stats/states/graphs etc. The cron jobs are running and polling etc. - the state of devices updates dynamically via the map too.
However, there are no updates to the any of the graphs. I'm not sure if there is a database problem, RRD problem or file permissions problem. Placing /debug after various pages does not reveal any problems. Can anyone recommend other places to look for debug/logging information?
Thanks in advance
