getProfile method

Future<GetProfileResponse> getProfile({ required String profilingGroupName, String? accept, DateTime? endTime, int? maxDepth, String? period, DateTime? startTime, })

Gets the aggregated profile of a profiling group for a specified time range. Amazon CodeGuru Profiler collects posted agent profiles for a profiling group into aggregated profiles. Specify the time range for the requested aggregated profile using 1 or 2 of the following parameters: startTime, endTime, period. The maximum time range allowed is 7 days. If you specify all 3 parameters, an exception is thrown. If you specify only period, the latest aggregated profile is returned.

Aggregated profiles are available with aggregation periods of 5 minutes, 1 hour, and 1 day, aligned to UTC. The aggregation period of an aggregated profile determines how long it is retained. For more information, see AggregatedProfileTime . The aggregated profile's aggregation period determines how long it is retained by CodeGuru Profiler.

• If the aggregation period is 5 minutes, the aggregated profile is retained for 15 days.
• If the aggregation period is 1 hour, the aggregated profile is retained for 60 days.
• If the aggregation period is 1 day, the aggregated profile is retained for 3 years.

There are two use cases for calling GetProfile.

1. If you want to return an aggregated profile that already exists, use ListProfileTimes to view the time ranges of existing aggregated profiles. Use them in a GetProfile request to return a specific, existing aggregated profile.
2. If you want to return an aggregated profile for a time range that doesn't align with an existing aggregated profile, then CodeGuru Profiler makes a best effort to combine existing aggregated profiles from the requested time range and return them as one aggregated profile.

   If aggregated profiles do not exist for the full time range requested, then aggregated profiles for a smaller time range are returned. For example, if the requested time range is from 00:00 to 00:20, and the existing aggregated profiles are from 00:15 and 00:25, then the aggregated profiles from 00:15 to 00:20 are returned.

May throw InternalServerException. May throw ResourceNotFoundException. May throw ThrottlingException. May throw ValidationException.

Parameter profilingGroupName : The name of the profiling group to get.

Parameter accept : The format of the returned profiling data. The format maps to the Accept and Content-Type headers of the HTTP request. You can specify one of the following: or the default .

• application/json — standard JSON format
• application/x-amzn-ion — the Amazon Ion data format. For more information, see Amazon Ion.

Parameter endTime : The end time of the requested profile. Specify using the ISO 8601 format. For example, 2020-06-01T13:15:02.001Z represents 1 millisecond past June 1, 2020 1:15:02 PM UTC.

If you specify endTime, then you must also specify period or startTime, but not both.

Parameter maxDepth : The maximum depth of the stacks in the code that is represented in the aggregated profile. For example, if CodeGuru Profiler finds a method A, which calls method B, which calls method C, which calls method D, then the depth is 4. If the maxDepth is set to 2, then the aggregated profile contains representations of methods A and B.

Parameter period : Used with startTime or endTime to specify the time range for the returned aggregated profile. Specify using the ISO 8601 format. For example, P1DT1H1M1S.

To get the latest aggregated profile, specify only period.

Parameter startTime : The start time of the profile to get. Specify using the ISO 8601 format. For example, 2020-06-01T13:15:02.001Z represents 1 millisecond past June 1, 2020 1:15:02 PM UTC.

If you specify startTime, then you must also specify period or endTime, but not both.
