Case 4 · 05:00 Synthetic Monitoring + 120 Hosts
This case shows a morning synthetic monitoring setup: at 05:00, 12 end-to-end probes (curl and SQL*Plus) run across the stack while 120 hosts are covered by system monitoring. Issues are found about 3.5 hours before peak usage, so daytime incidents are smaller and easier to handle.

What you’re seeing: success/failure for synthetic probes, host-level metrics, and time-to-fix for morning incidents. The dashboard answers a simple question: “How many problems did we catch before customers started their day?”

How to read & interact
- Follow the 05:00 probes: see which synthetic checks (HTTP/SQL) failed, how early they were detected, and which systems they touched.
- Connect to host health: compare probe failures with CPU, memory, disk, and process metrics on the 120 monitored hosts.
- Learn from incidents: review how many events were prevented before 9 a.m., and how the morning run shortened daytime troubleshooting.
