## frontend: mean_successful_sentinel_duration_over_2h

<p class="subtitle">mean successful sentinel search duration over 2h</p>

**Descriptions**

- <span class="badge badge-warning">warning</span> frontend: 5s+ mean successful sentinel search duration over 2h for 15m0s
- <span class="badge badge-critical">critical</span> frontend: 8s+ mean successful sentinel search duration over 2h for 30m0s

**Next steps**

- Look at the breakdown by query to determine if a specific query type is being affected
- Check for high CPU usage on zoekt-webserver
- Check Honeycomb for unusual activity
- More help interpreting this metric is available in the [dashboards reference](dashboards#frontend-mean-successful-sentinel-duration-over-2h).
- **Silence this alert:** If you are aware of this alert and want to silence notifications for it, add the following to your site configuration and set a reminder to re-evaluate the alert:

```json
"observability.silenceAlerts": [
"warning_frontend_mean_successful_sentinel_duration_over_2h",
"critical_frontend_mean_successful_sentinel_duration_over_2h"
]
