[Question] Can the monitoring center aggregate and query the historical data of monitoring hosts

### Question

Hello, I saw in the monitoring center that only a single host can be selected to view historical monitoring data. Can multiple hosts be selected to view the aggregated data of a monitoring item.
Can you provide a query page like promethues to query monitoring data through Qsql statements.

The issue refers to the monitoring center's historical-data view and requests multi-host aggregation plus a Prometheus-like QSQL query page. Start by tracing the existing monitoring-center historical-data flow and checking how monitoring data is currently queried. Done would require an agreed scope and working support for the requested aggregation and query experience.
