Ques. 5): I've already included a lot of logging into my code. Do I need to profile anymore?

Answer:

Because logging can only monitor latency (not CPU utilisation) and is labor-intensive to implement because developers must log every function in an application (without affecting application performance), it is only useful for a small number of scenarios, leaving developers without the resources they need to effectively monitor and troubleshoot applications in production. Here's where profiling is useful: Amazon Regardless of scenarios, CodeGuru Profiler is made to gather information on everything that transpired during that application's activity. Code patterns in your live application that affect performance are automatically found by CodeGuru Profiler using a knowledge base of frequently encountered performance inefficiencies.

Ques. 6): What is the operation of Amazon CodeGuru Profiler?

Answer:

An agent, the profiler service, and intelligent recommendations make up Amazon CodeGuru Profiler. The agent operates as an in-process thread as a component of your application and is launched along with it via the command line. Every five minutes, it sends data from each of your agent-running service instances to the profiler service, which aggregates it. The profile data is then made available by Amazon CodeGuru Profiler in the form of interactive flame graphs, allowing you to see how well your application is doing. Additionally, Amazon CodeGuru Profiler regularly analyses the profiled data, compares it to Amazon and performance engineering best practises, and proactively notifies you of performance issues with wise advice. It also uses machine learning to continuously analyze application runtime data and alerts when it detects anomalies in the application profile and points to the anomalous lines of code.

Ques. 7): What can I do with information from a heap summary?

Answer:

Two situations make advantage of heap summarization. You can first look for potential memory leaks. A leak that could result in out-of-memory issues and programme crashes may be indicated by a steadily rising memory use curve for one or more object types. When you want to reduce the memory footprint of your programme, that is the second situation. You can choose where to focus in this situation by looking at the breakdown of memory usage by object type. For instance, you can concentrate your research and optimization efforts on the areas of your application that are in charge of allocating and referring objects of a given kind if you are aware that an unexpectedly high amount of memory has been associated with a particular object type.

Ques. 10): The operation of the Amazon CodeGuru Reviewer Security Detector.

Answer:

The CodeGuru Reviewer Security Detector analyses code statically to provide a control-flow diagram of every potential execution scenario. Once data flow across the control-flow graph has been detected, possible problems requiring long sequences of operations involving several methods and classes may be found. For instance, even though initialization and use take place in different ways, the security detector can tell whether Javax.Crypto.KeyGenerator or Python's crypto.secrets, both of which are symmetric secret key generators, are initialised before use.

Ques. 12): What effects does CodeGuru Profiler have on the efficiency of programmes running on AWS Lambda?

Answer:

The agent for Amazon CodeGuru Profiler makes use of the CPU and memory resources allotted to AWS Lambda operations. It is optimised to have a negligible effect on the performance of your programme while it is running as an in-process thread. Consider raising the resources if your application uses the majority of them in an AWS Lambda function so that the agent can operate as intended.

Ques. 15): What distinguishes the Amazon CodeGuru Profiler from standard APMs and standalone profilers?

Answer:

Traditional APMs offer helpful information on application performance, monitoring, and tracing. These APM capabilities are complemented by Amazon CodeGuru Profiler, which offers visualisations of the application's runtime data in addition to suggestions for fixing any performance issues it finds. Additionally, it makes use of machine learning to find and notify you to anomalies in your application profile and identify the offending lines of code. Without having a strong expertise in performance engineering, you may use Amazon CodeGuru Profiler to quickly identify the areas of code that provide the most potential for speed optimization and cost reductions and obtain advice on how to address them. AWS Lambda, EC2 instances, containers, and on-premises serverless computing platforms are all profiled by Amazon CodeGuru Profiler. Additionally, while Amazon CodeGuru Profiler was created to run continuously in production, under production traffic levels, and without affecting the application, other standalone profilers are only intended to run in test environments. This is helpful when resolving operational problems in the field, especially those that arise while using bare metal hosts.
