Constructor Details

#initialize(config: nil, region: nil, endpoint: nil, signer: nil, proxy_settings: nil, retry_config: nil) ⇒ QueryClient

Creates a new QueryClient. Notes: If a config is not specified, then the global OCI.config will be used.

This client is not thread-safe

Either a region or an endpoint must be specified. If an endpoint is specified, it will be used instead of the region. A region may be specified in the config or via or the region parameter. If specified in both, then the region parameter will be used.

Parameters:

  • config (Config) (defaults to: nil) —

    A Config object.

  • region (String) (defaults to: nil) —

    A region used to determine the service endpoint. This will usually correspond to a value in Regions::REGION_ENUM, but may be an arbitrary string.

  • endpoint (String) (defaults to: nil) —

    The fully qualified endpoint URL

  • signer (OCI::BaseSigner) (defaults to: nil) —

    A signer implementation which can be used by this client. If this is not provided then a signer will be constructed via the provided config. One use case of this parameter is instance principals authentication, so that the instance principals signer can be provided to the client

  • proxy_settings (OCI::ApiClientProxySettings) (defaults to: nil) —

    If your environment requires you to use a proxy server for outgoing HTTP requests the details for the proxy can be provided in this parameter

  • retry_config (OCI::Retry::RetryConfig) (defaults to: nil) —

    The retry configuration for this service client. This represents the default retry configuration to apply across all operations. This can be overridden on a per-operation basis. The default retry configuration value is nil, which means that an operation will not perform any retries

def initialize(config: nil, region: nil, endpoint: nil, signer: nil, proxy_settings: nil, retry_config: nil)
  # If the signer is an InstancePrincipalsSecurityTokenSigner or SecurityTokenSigner and no config was supplied (they are self-sufficient signers)
  # then create a dummy config to pass to the ApiClient constructor. If customers wish to create a client which uses instance principals
  # and has config (either populated programmatically or loaded from a file), they must construct that config themselves and then
  # pass it to this constructor.
  #
  # If there is no signer (or the signer is not an instance principals signer) and no config was supplied, this is not valid
  # so try and load the config from the default file.
  config = OCI::Config.validate_and_build_config_with_signer(config, signer)

  signer = OCI::Signer.config_file_auth_builder(config) if signer.nil?

Instance Method Details

#list_quick_picks(apm_domain_id, opts = {}) ⇒ Response

Note:

Click here to see an example of how to use list_quick_picks API.

Returns a list of predefined Quick Pick queries intended to assist the user to choose a query to run. There is no sorting applied on the results.

Parameters:

  • apm_domain_id (String) —

    The APM Domain ID for the intended request.

  • opts (Hash) (defaults to: {}) —

    the optional parameters

Options Hash (opts):

  • :retry_config (OCI::Retry::RetryConfig) —

    The retry configuration to apply to this operation. If no key is provided then the service-level retry configuration defined by #retry_config will be used. If an explicit nil value is provided then the operation will not retry

  • :opc_request_id (String) —

    Unique Oracle-assigned identifier for the request. If you need to contact Oracle about a particular request, please provide the request ID.

  • :limit (Integer) —

    The maximum number of items to return. (default to 50)

  • :page (String) —

    The page token representing the page where to start retrieving results. This is usually retrieved from a previous response. (default to 1)

Returns:

#query(apm_domain_id, time_span_started_greater_than_or_equal_to, time_span_started_less_than, query_details, opts = {}) ⇒ Response

Note:

Click here to see an example of how to use query API.

Retrieves the results (selected attributes and aggregations) of a query constructed according to the Application Performance Monitoring Defined Query Syntax. Query results are filtered by the filter criteria specified in the where clause. Further query results are grouped by the attributes specified in the group by clause. Finally, ordering (asc/desc) is done by the specified attributes in the order by clause.

Parameters:

  • apm_domain_id (String) —

    The APM Domain ID for the intended request.

  • time_span_started_greater_than_or_equal_to (DateTime) —

    Include spans that have a spanStartTime equal to or greater than this value.

  • time_span_started_less_than (DateTime) —

    Include spans that have a spanStartTimeless than this value.

  • query_details (OCI::ApmTraces::Models::QueryDetails) —

    Request body containing the query to be run against the trace data and to filter and retrieve trace data results.

  • opts (Hash) (defaults to: {}) —

    the optional parameters

Options Hash (opts):

  • :retry_config (OCI::Retry::RetryConfig) —

    The retry configuration to apply to this operation. If no key is provided then the service-level retry configuration defined by #retry_config will be used. If an explicit nil value is provided then the operation will not retry

  • :opc_request_id (String) —

    Unique Oracle-assigned identifier for the request. If you need to contact Oracle about a particular request, please provide the request ID.
