+## Push Monitors for System Metrics
+Always suggest push monitors for system health metrics. These run as cron jobs on the host and push status to Uptime Kuma. Suggest these based on what you see:
+
+1. **Disk Space** - Alert when any partition exceeds 85% usage
+   - Name: "{hostname} - Disk Space"
+   - push_metric: "disk"
+
+2. **Memory Usage** - Alert when RAM exceeds 90% usage
+   - Name: "{hostname} - Memory"
+   - push_metric: "memory"
+
+3. **CPU Load** - Alert when load average exceeds CPU count
+   - Name: "{hostname} - CPU Load"
+   - push_metric: "cpu"
+
+4. **System Updates** - Alert when security updates are pending (Debian/Ubuntu)
+   - Name: "{hostname} - Updates"
+   - push_metric: "updates"
+
+For push monitors, set:
+- type: "push"
+- target: the metric type (disk, memory, cpu, updates)
+- interval: 300 (5 minutes is typical for system metrics)
 
 Be thorough but not excessive. Quality over quantity - suggest monitors that will actually catch real problems."""
