Description

A kind of function call tracker and tracking

Technical field

The present invention relates to software systems follows the tracks of and system's operation monitoring technology.

Background technology

Modern software systems problem to be solved becomes increasingly complex, and its scale and complexity are also more and more higher.At present, modularized design method is generally adopted in application system development.Software systems are made of each functional module, each sub-function module is finished single relatively specific function, the realization of the function point of each functional module is called by a series of function (method) and is finished, and function (method) is the minimum component units of sub-function module.The function that submodule need be realized is very single-minded, and the design of submodule realizes also simple relatively, and such method for designing helps designing easily, also is convenient to the multi-person synergy exploitation.Simultaneously, by the interface of well-designed intermodule, the change that makes a certain functional module is reduced to minimum level to the influence of other modules, and this effectively reduces improved workload of system upgrade and fallibility in the future.

Independent sub-function module does not have practical significance, each subfunction of system must be shared out the work and helped one another to realize the required work of finishing of software systems, this just needs to call mutually between them, coupling between each submodule is inevitable like this, and each submodule carries part and the irrelevant extra section of its Core Feature always.One of groundwork of modern procedures designer is exactly to seek the whole bag of tricks the degree of coupling between functional module is reduced to bottom line.

In the modern Application system, the designer needs on top of operational scheme, running status and the operational factor of system, reach such purpose, need add tracker at the focus place of system.When this focus activated, tracker can be according to the mode of hope, and the operational factor that the designer need be paid close attention to outputs to appointed positions with the form of expecting.Adopt in the modular design method designed system at one, the implementation of prior art is that the format that will comprise output information, outgoing position, output action itself etc. are organized in the functional module, and this module can be called tracking module.It externally only provides an entrance, i.e. ' tracking ' of tracker action.This tracking module is arranged on the focus place of internal system.The shortcoming of this scheme is as follows:

1, need all quote tracking module at each focus place, if focus is a lot, the workload of then designing and developing is very big;

2, at each focus place, tracker action is set is repetition, if the inlet of tracking module is realized changing, then need the tracker setting at every place in the modification system.When focus was a lot, the workload of modification was very big.If weigh the degree of coupling of business module and tracking module with the number of times that tracking is set, even if adopt modular design as can be seen, the degree of coupling also can the linear increase with the increase of focus.In other words, following function has spread with the increase of focus.

3, for cooperating tracking module work, where and how business module need be arranged on exports operational factor to assigned address, thereby, in business module, have with the irrelevant function of its Core Feature and realize existing.

How to address the aforementioned drawbacks, be purpose of the present invention.
