Hi, is there any document or video reference to use PromQL queries for creating alerts in SigNoz?

Hey <@U08MZ5Y7LR5> do you want to understand how to write promql queries?

Yes, I want to write PromQL queries for system metrics in SigNoz.

here is the doc for understanding PromQL queries: <https://prometheus.io/docs/prometheus/latest/querying/basics/>

Once you write the queries you can create alerts based on these queries:
<https://signoz.io/docs/alerts/>

As the document only covers the metrics query builder, I'm looking for a reference on how to use PromQL directly.

Do you want to know where to use promql queries while defining the alerts, rather than query builder?

Nope,  Is there an option, like in other observability tools, where selecting metrics in the UI also generates the corresponding query.
