You don’t wait for Level 4 to use these
From day one with infrastructure monitoring, you have access to powerful operational tools. The same tools work at every level; only the scope changes.
Here’s what they look like at Level 1
Alerting
| What to alert on | Example |
|---|
| Host health | CPU > 90%, memory > 85%, disk > 80% |
| Integration status | MySQL connection failed, NGINX not responding |
| Basic availability | Host unreachable, service down |
Dashboards
| Dashboard type | What you see |
|---|
| Pre-built integration dashboards | Comes with every integration for instant visibility |
| Infrastructure overview | All hosts, key metrics at a glance |
| Custom dashboards | Combine metrics from multiple integrations |
Investigation
| Tool | How you use it at Level 1 |
|---|
| Explore | Ad-hoc queries on metrics and logs |
| Drilldown apps | Click from dashboard → detailed investigation |
| Logs → Metrics correlation | “What was happening on this host when CPU spiked?” |
SLOs
| SLO Example | Target |
|---|
| Host uptime | 99.9% of hosts healthy |
| Database availability | 99.5% connection success rate |
These same tools grow with you. At Level 2, you’ll alert on services. At Level 3, on transactions. At Level 4, on custom metrics. The concepts stay the same; only the scope changes.
