I am writing to report an issue with a Grafana dashboard. Currently, the dashboard is not functioning correctly; only a few widgets are loading successfully, while others are failing to display data.
The widgets that are failing to load show the following error message:
“context deadline exceeded: Could not process SQL results”
Hello @tamilmaniperumal
Welcome to grafana community
The error message “context deadline exceeded: Could not process SQL results” in Grafana indicates a timeout may be Heavy Queries, Low Timeout Limits
Try
Increase Data Source Timeout
Optimize the SQL Query (use grafana transformation if multiple series return ie reduce)
Check Connection Settings (grafana.ini → Maxconnection)
