How should I approach a Linux upgrade?
An upgrade needs a compatibility check, a tested release and a recovery path. Which changes deserve particular attention before the new version reaches production?
What needs backing up or preserving in Linux?
Recovery needs to recreate the working service and its required data after a machine or process is lost. Which artifacts and state need protection, and how should the restore be checked?
What should I check first when Linux fails?
A failure needs to be narrowed down before settings are changed or operations retried. Which evidence best separates application errors from environment and dependency problems?
How should I handle configuration and secrets in Linux?
Configuration must be available to the application without exposing credentials in source control, logs or browser code. What belongs in the runtime and which access controls matter?

Measure CPU saturation, memory pressure, disk latency and network throughput using workload-appropriate tools. Load average alone does not identify the bottleneck. Compare a baseline with one controlled change and check whether virtualization limits or application-level locks dominate the result.
