Yes, much thanks for the cool graphs. Does it tend to lag a few minutes/hours? or is it fairly real-time?
I collect a snapshot of the data every 10 minutes. The graphs should normally be about that up to date. The last few days there have been issues and the graphs may be lagging more than that, but hopefully they will be back to normal soon.
Individual user charts seem stuck again. No update in hours.
Main site chart seems ok though (ok in terms of updates, Cryptsy induced unexchanged rates notwithstanding).
The graph code may still have some problems this morning but I think I discovered the underlining problem. The server that the virtual machine was running on at Rackspace had problems. I had them migrate me to a different server and my performance issues went away.
What was happening was that the CPU would go to 100% while running the graph code and eventually things would bog down to the point that I would have to reboot the server. I did a bunch of work to improve performance but in the end the problem wasn't my fault. (things are running faster now though
.
Reboots always hung and I'd have to get a tech to help. On about the fifth reboot late last night, the guy noticed there were a bunch of other instances on the same server having problems and recommended migration. They did that some time in the night.
So, any remaining problems are probably due to changes I made trying to fix things. I should have things back later today.
