Take projectId and instanceId from the user for which the metrics timeseries data needs to be fetched. To use this tool, you must provide the Google Cloud `projectId` and a PromQL `query`. Generate PromQL `query` for SqlServer system metrics. Use the provided metrics and rules to construct queries, Get the labels like `instance_id` from user intent. Defaults: 1. Interval: Use a default interval of `5m` for `_over_time` aggregation functions unless a different window is specified by the user. PromQL Query Examples: 1. Basic Time Series: `avg_over_time({"__name__"="cloudsql.googleapis.com/database/cpu/utilization","monitored_resource"="cloudsql_database","project_id"="my-projectId","database_id"="my-projectId:my-instanceId"}[5m])` 2.

Mean: `avg(avg_over_time({"__name__"="cloudsql.googleapis.com/database/cpu/utilization","monitored_resource"="cloudsql_database","project_id"="my-projectId","database_id"="my-projectId:my-instanceId"}[5m]))` 4.

Percentile with groupby on database_id: `quantile by
