In this tutorial, you take a tour of the process of collecting and downloading traces. The Trace parser tool works much like the Microsoft Dynamics AX 2012 version, but it isn't backward compatible and can't be used to analyze AX 2012 traces. You can find the tool in your development environments. On the Windows Start menu, select Microsoft Dynamics Trace Parser. Alternatively, open C:\Program Files (x86)\Microsoft Dynamics Trace Parser\Microsoft.Dynamics.AX.Tracing.TraceParser.exe.
By setting a maximum file size, you help make the traces more manageable when you import them into the Trace parser tool. You can set the data collector properties to restart after a specified number of megabytes (MB).

This article explains how you can use the Trace parser to consume traces and analyze performance in your deployment. You can use the Trace Parser to find and diagnose various types of errors. You can also use the tool to visualize execution of X++ methods, as well as the execution call tree.
Trace parser should be preinstalled with your developer deployment or VHD. The install location is here: C:\Program Files (x86)\Microsoft Dynamics Trace Parser. If it's not installed, you can run the installer from C:\PerfSDK\PerfTools\traceparser.msi.
How can I enable tracing of the DB interactions (SQL statements)? In AX 2012 I remember there was a small from, I think under Tools, where you can tick what to trace and SQL was one of the tickboxes. I tried to trace a few things in D365 where thre is definitely some DB action going on, but it never appears in the trace parser (Database Time, Database Calls column is empty everywhere and also when I drill down into X++ where I expect SQL, there is nothing). Maybe I am also missing some settings in the parser itself.
Well there are many scenarios where tracer parser can be useful.One scenario would be like to know the reason why a specific business process is consuming more time than expected like Form is consuming more time to open or custom posting process is very slow. To trace a scenario, we start the trace, perform required business operation(exactly) ,stop the trace and collect it in tracer parser UI to analyze. General recommendations are to keep the trace short & upto the scenario and only one user should loginto AX while performing an operation to avoid unwanted traces.
Trace parser is a performance analyzing tool that helps to identify the performance bottlenecks such as long-running X++ methods(both custom & standard), time-consuming SQL queries and client-server calls. We have server and client trace that gets generated separately and can examine their behavior individually.
I have managed to solve this issue by capturing the trace from Trace parser with all providers selected. It probably installs the missing providers. Since then capturing the trace from GUI works normally.
If you have to trace longer processes on your development VM you can extend the limit of the trace to whatever limit you want. Nevertheless I would recommend to do not extend it too much, because then you will get into trouble when importing the files into trace parser. To extend the limit you have to change the value MaximumEtlFileSizeInMb in file AOSService\webroot\Services\TraceParserService\TraceParserService.config.
Looking at these SQL traces can reveal issues with inadequate tracing. Some CRT base entities are cached, so you will only see a single call (per RetailServer instance) but if you extend an entity you need to make sure you implement some caching as well if this meets the requirement. For example, fetching an item in the CRT base implementation is cached, so you should only see that call once but if you extended the item with an extension table AND did not use any caching, you will see many calls with the same query during POS operations that require an item lookup. That would indicate that caching should be considered. The caching of a CRT extended entity will be covered in a different blog.
Our design of this device engages several brain areas, as well as fibers of synapses connecting these areas, and uses the operations of the AC, enhanced in small ways explained in Section 3. It would in principle be possible to use the original set of AC operations in Papadimitriou et al. (2020), but this would complicate its operation and entail the introduction of more brain areas.2 The resulting device relies on powerful word representations, and is essentially a lexicalized parser, producing something akin to a dependency graph.
In particular, we are not claiming that our implementation of the Parser necessarily resembles the way in which the brain actually implements language, or that it can predict experimental data. Rather, we see the parser as an existence proof of a nontrivial linguistic device built entirely out of simulated neuron dynamics.
In a recent paper (Papadimitriou et al., 2020), a concrete mathematical formalization of assemblies is proposed. They demonstrate that this simplified model is capable of simulating assembly dynamics that are known experimentally. This model of neurons, assemblies, and their dynamics can be viewed as a computational system, called the Assembly Calculus (AC), bridging neuronal dynamics with cognition; this is the computational system in which we implement our parser. The AC is summarized in Section 3. Note that it has been long debated whether language is a highly specialized system or is based in general cognitive faculties (see, e.g., the summary of the debate in Lewis and Vasishth [2005]). We are agnostic in this debate, because assemblies are the proposed unit of neural computation both specialized and generic, having been studied across a variety of systems and species (Miller et al., 2014; Carrillo-Reid et al., 2018). e24fc04721
