AWS Performance Insights 2018-02-27

Client: Aws\PI\PIClient
Service ID: pi
Version: 2018-02-27

This page describes the parameters and results for the operations of the AWS Performance Insights (2018-02-27), and shows how to use the Aws\PI\PIClient object to call the described operations. This documentation is specific to the 2018-02-27 API version of the service.

Operation Summary

Each of the following operations can be created from a client using $client->getCommand('CommandName'), where "CommandName" is the name of one of the following operations. Note: a command is a value that encapsulates an operation and the parameters used to create an HTTP request.

You can also create and send a command immediately using the magic methods available on a client object: $client->commandName(/* parameters */). You can send the command asynchronously (returning a promise) by appending the word "Async" to the operation name: $client->commandNameAsync(/* parameters */).

Paginators

Paginators handle automatically iterating over paginated API results. Paginators are associated with specific API operations, and they accept the parameters that the corresponding API operation accepts. You can get a paginator from a client class using getPaginator($paginatorName, $operationParameters). This client supports the following paginators:

DescribeDimensionKeys
GetResourceMetrics
ListAvailableResourceDimensions
ListAvailableResourceMetrics
ListPerformanceAnalysisReports

AdditionalMetrics
Type: Array of strings

Additional metrics for the top N dimension keys. If the specified dimension group in the GroupBy parameter is db.sql_tokenized, you can specify per-SQL metrics to get the values for the top N SQL digests. The response syntax is as follows: "AdditionalMetrics" : { "string" : "string" }.

EndTime
Required: Yes
Type: timestamp (string|DateTime or anything parsable by strtotime)

The date and time specifying the end of the requested time series data. The value specified is exclusive, which means that data points less than (but not equal to) EndTime are returned.

The value for EndTime must be later than the value for StartTime.

Filter
Type: Associative array of custom strings keys (SanitizedString) to strings

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

  • Any number of filters by the same dimension, as specified in the GroupBy or Partition parameters.

  • A single filter for any other dimension in this dimension group.

The db.sql.db_id filter isn't available for RDS for SQL Server DB instances.

GroupBy
Required: Yes
Type: DimensionGroup structure

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

Identifier
Required: Yes
Type: string

An immutable, Amazon Web Services Region-unique identifier for a data source. Performance Insights gathers metrics from this data source.

To use an Amazon RDS instance as a data source, you specify its DbiResourceId value. For example, specify db-FAIHNTYBKTGAUSUZQYPDS2GW4A.

MaxResults
Type: int

The maximum number of items to return in the response. If more items exist than the specified MaxRecords value, a pagination token is included in the response so that the remaining results can be retrieved.

Metric
Required: Yes
Type: string

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.

NextToken
Type: string

An optional pagination token provided by a previous request. If this parameter is specified, the response includes only records beyond the token, up to the value specified by MaxRecords.

PartitionBy
Type: DimensionGroup structure

For each dimension specified in GroupBy, specify a secondary dimension to further subdivide the partition keys in the response.

PeriodInSeconds
Type: int

The granularity, in seconds, of the data points returned from Performance Insights. A period can be as short as one second, or as long as one day (86400 seconds). Valid values are:

  • 1 (one second)

  • 60 (one minute)

  • 300 (five minutes)

  • 3600 (one hour)

  • 86400 (twenty-four hours)

If you don't specify PeriodInSeconds, then Performance Insights chooses a value for you, with a goal of returning roughly 100-200 data points in the response.

ServiceType
Required: Yes
Type: string

The Amazon Web Services service for which Performance Insights will return metrics. Valid values are as follows:

  • RDS

  • DOCDB

StartTime
Required: Yes
Type: timestamp (string|DateTime or anything parsable by strtotime)

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.
