(2) size of timing circularly monitoring journal file, step 21: system is with the size of the current journal file of quantitative check during program run, and judge whether to need then write next file, if the maximum set value of the odd-numbered day will file that the size of current journal file is set during less than initialization, then jump procedure 26, otherwise change step 22, for example: if the current file pointer is " 3 ", substantially " Radius.log " by name of file, then current journal file is called " Radius3.log ", if timer is checked through the maximal value that the size of file " Radius3.log " surpasses single file, then change step 22: close current journal file Radius3.log, step 23: use the round-robin method, make that file pointer is " 4 ", obtain new journal file name Radius4.log, step 24: open file " Radius4.log " step 25 with the mode of emptying: record " 4 " this new journal file pointer value in pointer file; Step 26: finish the interval time of waiting for a setting, and circulation enters regularly monitors flow process;
(3) real time record is preserved log information when entering regularly circularly monitoring, can preserve information at any time during program run, only needs to use two parameters, for example:
PTRACE(3，″Message?no：″＜＜no)；
First parameter " 3 " wherein represents that the preservation rank of this information is 3, if the preservation rank that the user is provided with when initialization is not then printed this information, otherwise printed this information less than 3." Message no: " in second parameter is a character string, and " no " is an integer variable.If the value of no is 3, then the result is:
2000/11/12?10:20:51?243?host.cpp(478)Message?no：3
Wherein " 243 " expression thread number this line code that has been 243 thread execution, 478th row of the code of this information at the host.cpp file printed in " host.cpp (478) " expression; Step 31: the preservation rank of setting when writing rank that log pattern judges current system log message whether smaller or equal to initialization, if the preservation rank of information is preserved rank greater than the system that sets, then jump procedure 36, otherwise change step 32; Step 32:, at first utilize mutual exclusion techniques to lock in order to guarantee thread-safe; Step 33: get time, thread number then, according to current configuration requirement, the filename of date saved, thread number, source program, row number, information such as log content are in current journal file; Step 34: line feed, and refreshing file; Step 35: added lock in the release steps 32; Step 36: receive next bar log information.
In step 11, the content of the information of printing is set, comprising: whether print source filename, whether print the row number of source file and whether print the current thread numbering.
In step 11, the rank that needs to preserve log information represents to preserve the system information of rank smaller or equal to setting value, and every system information all has a level definition, and the importance that rank is more little is high more.
Pointer file in the step 11 is preserved the journal file numbering when withdrawing from the pointer file when logging off; When system moves, current journal file numbering is kept in the pointer file.
The module composition synoptic diagram of system of the present invention shown in Figure 4 has been done detailed explanation in the above and has just been repeated no more herein;
