Program narrative
We walk through quota math with real numbers from classroom machines, then break things on purpose: runaway debug flags, duplicate units, and remote forwarding loops. You leave with rotation snippets tested against our sample retention policy.
What the labs include
- Quota spreadsheets you can adapt to your org
- Remote forwarding pitfalls and TLS offload notes
- Structured fields vs plain text tradeoffs
- Hands-on disk fill drill with safe snapshots
- Pair review of anonymized excerpts
- Checklist for vendor appliances that hide logs
- Quiet hours alerting pattern
Outcomes you can show a lead
- Pick a retention tier that matches disk reality
- Spot duplicate ingestion before it doubles storage
- Present a one-slide summary stakeholders understand
Straight FAQ
Will we cover third-party agents?
We reference common agents but labs stay on journald-first stacks to keep time focused.
Can I bring anonymized configs?
Yes, mentors review them in office hours if they fit the cohort theme.
Limitations?
Windows event forwarding is not covered; we stay on Linux-native paths.
Recent participant notes
“Short course, dense. I wanted one more hour on remote TLS, but the disk fill drill finally scared my team into action.”
