The monitoring techniques discussed so far in this book can become unmanageable for installations with more than a few servers. Indeed, manual monitoring and reporting can turn into a full-time job for one or more technicians in an organization with dozens of servers. We focus on monitoring in this chapter, but the same can be said about administration. Specifically, administrators often see time savings when they use administration tools that permit automation of common tasks, such as running scripts to populate tables, performing table mainte- nance, etc. Fortunately, this problem isn't new, nor is it insurmountable.
