Struct PerformanceInsightsMetricQuery

#[non_exhaustive]
pub struct PerformanceInsightsMetricQuery {
    pub metric: Option<String>,
    pub group_by: Option<PerformanceInsightsMetricDimensionGroup>,
    pub filter: Option<HashMap<String, String>>,
}

A single query to be processed. Use these parameters to query the Performance Insights GetResourceMetrics API to retrieve the metrics for an anomaly. For more information, see GetResourceMetrics in the Amazon RDS Performance Insights API Reference.

Amazon RDS Performance Insights enables you to monitor and explore different dimensions of database load based on data captured from a running DB instance. DB load is measured as average active sessions. Performance Insights provides the data to API consumers as a two-dimensional time-series dataset. The time dimension provides DB load data for each time point in the queried time range. Each time point decomposes overall load in relation to the requested dimensions, measured at that time point. Examples include SQL, Wait event, User, and Host.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

metric: Option<String>

The name of the meteric used used when querying an Performance Insights GetResourceMetrics API for anomaly metrics.

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.

group_by: Option<PerformanceInsightsMetricDimensionGroup>

The specification for how to aggregate the data points from a Performance Insights GetResourceMetrics API query. The Performance Insights query returns 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.

filter: Option<HashMap<String, String>>

One or more filters to apply to a Performance Insights GetResourceMetrics API query. 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.

Implementations

impl PerformanceInsightsMetricQuery

pub fn metric(&self) -> Option<&str>

The name of the meteric used used when querying an Performance Insights GetResourceMetrics API for anomaly metrics.

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.

pub fn group_by(&self) -> Option<&PerformanceInsightsMetricDimensionGroup>

The specification for how to aggregate the data points from a Performance Insights GetResourceMetrics API query. The Performance Insights query returns 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.

pub fn filter(&self) -> Option<&HashMap<String, String>>

One or more filters to apply to a Performance Insights GetResourceMetrics API query. 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.

impl PerformanceInsightsMetricQuery

pub fn builder() -> PerformanceInsightsMetricQueryBuilder

Creates a new builder-style object to manufacture PerformanceInsightsMetricQuery.

Trait Implementations

impl Clone for PerformanceInsightsMetricQuery

fn clone(&self) -> PerformanceInsightsMetricQuery

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PerformanceInsightsMetricQuery

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for PerformanceInsightsMetricQuery

fn eq(&self, other: &PerformanceInsightsMetricQuery) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
