Server monitoring is usually reactive in nature. Some predefined threshold is exceeded, an alert is sent, and by the time you receive the alert, something bad has already happened. Wouldn’t it be nice to be able to foresee trouble before it rears its ugly head? We present our initial investigation into using analytical tools available within the R statistical environment to easily monitor server activity, predict potential performance problems, and possibly prevent faults on PostgreSQL database servers.
