[Pro]Active Sitecore Monitoring

When you hear the words "Application Lifecycle Management", the first thing that comes into your mind is likely Build / Deploy / Test workflow. But there is one thing which is missing here, and it is called "Monitoring".

Once you've deployed the website, you'll see that website performance may vary a lot depending on many known and unknown factors. They can be caused by both external (such as bot traffic, daily visits spikes, membership providers (CRM, AD) performance) and internal (different Sitecore jobs, scheduled tasks, automations, etc.) factors.

How do you know how the website performs? It's not something that you'll find in Sitecore logs, and it's not one hundred percent clear from IIS logs either.
