Core Tools, Telemetry, and What to Capture
Map the first checks, high-value signals, and escalation triggers across endpoints, networks, applications, databases, and AI systems.
The strongest troubleshooting habit is not tool memorization. It is knowing which evidence matters first and why.
This chapter turns common support tools into an evidence framework. Learners see which tools belong to which layer, what “good” looks like, which signals are high-value, and when the risk or complexity crosses into escalation territory.
