Monitoring

Around 12:35-12:40 UTC there was a severe increase in load on the RIPEstat application servers. This caused the application servers to start swapping, and performance to degrade. Between 14:00-14:05 requests started to fail.

The root cause seems to be a shift in request pattern.

The situation was complicated by a change in configuration management that meant we could not restart our application processes in big batches, but had to do this machine-by-machine.

As an intervention we will limit swap usage by our python processes to make failures (and recovery from failures) faster.
