> Set threshold alerts on aggregated log data, plus improved URL persistence for API Catalog tabs and Usage views for easier sharing of insights.

With this update to [**Scheduled Search**](https://app.last9.io/control-plane/scheduled-search), you can now set threshold-based alerts on aggregation queries, extending our log alerting capabilities beyond simple "found/not found" queries. This leverages ongoing improvements to our logs-to-metrics pipeline to bring advanced alerting capabilities to teams that primarily rely on logs.

**Benefits for logs-focused teams:**

- **Metrics-style alerting without a metrics pipeline:** monitor critical thresholds directly from your logs
- **Unlock hidden insights** in your existing log data without changing your instrumentation
- **Simplify your observability stack** by eliminating the need for separate metrics collection for basic alerting
- **Reduce MTTR** by correlating numerical patterns with detailed log context in a single platform

**Example use cases:**

- Track when HTTP 5xx errors exceed 5% of total requests using only your web server logs
- Alert when application response times in logs show p95 latency crossing 200ms
- Detect authentication anomalies by counting failed login patterns across distributed services
- Monitor infrastructure health using log-based resource utilization indicators

We’ve got some more updates to our logs-to-metrics pipeline lined. Meanwhile, [read the docs](https://last9.io/docs/scheduled-search/) for full setup details and best practices.

### Improvements

- [**API Catalog**](https://app.last9.io/api-catalog)**:**
  - Selected tab in the details side panel is now persisted in the URL for easier sharing with teammates
  - Improved availability chart display when error rate data is missing but throughput data is present, and 0% availability now aligned to bottom of chart instead of center
- [**Usage**](https://app.last9.io/control-plane/usage)**:** Selected date view and telemetry type selections are now preserved in the URL for easier sharing

### Fixes
