API Monitor

APIs (short for application programming interface) are sets of tools for building software applications. APIs are such a big part of our operating systems and programs because they specify the way all software components should work and interact with each other.

API Monitor is a complex piece of software that makes it as simple as possible for you to overview and control API calls made by your apps and services.

From a developer's standpoint, this makes the app quite useful, as it enables you to break down how apps and services actually work and track down possible interconnecting problems.

Subsequent to its installation and upon first opening the utility, you are greeted by a fairly crowded but comprehensive user interface. You get a small menu bar, a useful toolbar and panels that thoroughly display API filters, all running or monitored processes and summaries.

Noteworthy is the fact that API Monitor makes it possible for you to take advantage of the pre-defined layout options or fully customize the layout with the help of its dockable windows.

Right off the bat, you should know that the tool comes with support for a wide variety of DLLs and COM interfaces, as well as for an even broader number of tracking methods.

In terms of outright powerful features, you can find buffer and summary view with syntax highlighting, call tree panel, process memory monitor, call filtering, COM monitoring, error code decoder and call stack.

You can decode parameters and return values, add breakpoints and monitor APIs without creating definitions.

Considering all that has been said, API Monitor is a powerful app designed for software development purposes. However, it is in no case overly complicated, which means that it can be used by novice users without problems.

With a plethora of monitoring features, a customizable layout for its interface, decoders, filters, and loaders, API Monitor is what you would call a comprehensive app.
