Monitoring System Sprawl
This is often a corollary to the first point, not relying on manual processes. The number of monitoring systems you have in place should approach 1. You do not want one system to monitor windows servers; another for linux, another for MySQL, another for storage. Even if they are all capable of automatic updates, filtering and classifying, having multiple systems still virtually guarantees suboptimal datacenter performance. What happens when the DBA changes his pager address, and the contact information is updated in the escalation methods of 2 systems, but not the other 2? What happens when scheduled maintenance is specified in one system, but not another that is tracking another component of the systems undergoing maintenance?
