grafana refresh rate 3s

@Ramin Najafi Welcome to Microsoft Q&A

To set a 3-second refresh rate in Azure Managed Grafana, you’ll need to customize the dashboard or panel settings manually—Grafana doesn’t offer 3s as a default option in the dropdown, but you can add it yourself. Here's how:

Steps to Add a 3s Refresh Rate:

1- Open your dashboard in Azure Managed Grafana.

2- Click the refresh dropdown (top-right corner, next to the time range).

3- Scroll to the bottom and click "Add custom interval".

4- Type 3s and hit Enter.

You can also add multiple intervals like 3s,5s,10s if needed.

Select 3s from the list to activate it.

Things to Keep in Mind

Performance impact: Refreshing every 3 seconds can be heavy on your data source and Grafana backend. Use it only for lightweight queries or real-time dashboards.

Azure Monitor data source: If you're using Azure Monitor or Log Analytics, they may not support such frequent polling due to backend throttling. Prometheus and InfluxDB are better suited for high-frequency refreshes.

Permissions: You need Editor or Admin rights in Grafana to modify dashboard settings.
