## 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                |

### Investigation and RCA

| Tool                           | How you use it at Level 1                             |
|--------------------------------|-------------------------------------------------------|
| **Grafana Assistant**          | Ask natural language questions to surface root cause  |
| **Explore**                    | Ad-hoc queries on metrics and logs                    |
| **Drilldown apps**             | Jump from an alert into detailed signal 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.
