Your configuration management is fact-based.
Your orchestration is fact-based.
Is your monitoring fact-based?

What does that even mean? Monitoring is very similar to configuration, at least in its expression. Configuration cares about files, services, and hosts being present and in a certain state (""nginx should be running with the following configuration""). Monitoring cares about services being present, running, and in a certain state. Both describe your infrastructure as it should be (""nginx should be running and respond in less than 200ms"").

Fact-based monitoring is about being able to control monitoring with the same facts that Puppet uses (""monitor nginx latency wherever Puppet says it should run""). This is in contrast with imperative monitoring (""monitor nginx on host a, b and c"") that gets out of sync and leads to mailbox meltdowns from spurious alerts.

Using open source and commercial examples, this talk will help you express your monitoring in a way that will feel very natural to your Puppet configuration.
