class Aws::PI::Types::MetricQuery

A single query to be processed. You must provide the metric to query. If no other parameters are specified, Performance Insights returns all of the data points for that metric. You can optionally request that the data points be aggregated by dimension group ( `GroupBy`), and return only those data points that match your criteria (`Filter`).

@note When making an API call, you may pass MetricQuery

data as a hash:

    {
      metric: "RequestString", # required
      group_by: {
        group: "RequestString", # required
        dimensions: ["RequestString"],
        limit: 1,
      },
      filter: {
        "RequestString" => "RequestString",
      },
    }

@!attribute [rw] metric

The name of a Performance Insights metric to be measured.

Valid values for `Metric` are:

* `db.load.avg` - a scaled representation of the number of active
  sessions for the database engine.

* `db.sampledload.avg` - the raw number of active sessions for the
  database engine.

If the number of active sessions is less than an internal
Performance Insights threshold, `db.load.avg` and
`db.sampledload.avg` are the same value. If the number of active
sessions is greater than the internal threshold, Performance
Insights samples the active sessions, with `db.load.avg` showing the
scaled values, `db.sampledload.avg` showing the raw values, and
`db.sampledload.avg` less than `db.load.avg`. For most use cases,
you can query `db.load.avg` only.
@return [String]

@!attribute [rw] group_by

A specification for how to aggregate the data points from a query
result. You must specify a valid dimension group. Performance
Insights will return all of the dimensions within that group, unless
you provide the names of specific dimensions within that group. You
can also request that Performance Insights return a limited number
of values for a dimension.
@return [Types::DimensionGroup]

@!attribute [rw] filter

One or more filters to apply in the request. Restrictions:

* Any number of filters by the same dimension, as specified in the
  `GroupBy` parameter.

* A single filter for any other dimension in this dimension group.
@return [Hash<String,String>]
