Embodiment
The embodiment of the invention provides the method for supervising and the device at a kind of automatic road measuring terminal, in order to more easily the automatic road measuring terminal is monitored, improves monitoring efficiency, practices thrift product cost.
The embodiment of the invention is not carrying out through monitor terminal the automatic road measuring terminal being monitored under the situation of code revision to the automatic road measuring terminal to the automatic road measuring terminal basically.
The embodiment of the invention is monitored the automatic road measuring terminal through reading journal file, and has realized reading the daily record thread and write the synchronous of daily record thread, and the speed of reading thread is adjusted, so that be consistent basically with the speed of writing thread.
The monitor terminal that the embodiment of the invention provides; Do not adopt traditional message communicating mode (communication mode of socket); But adopted monitor terminal to read the daily record at automatic road measuring terminal; Thereby the mode of monitoring, and as a complete scheme, solved how the daily record read-write is carried out synchronously, daily record how breakpoint transmission and when reading daily record speed adjust to series of technical such as the best automatically.
Below in conjunction with accompanying drawing the technical scheme that the embodiment of the invention provides is described.
In the monitor terminal side, referring to Fig. 1, the method for supervising at a kind of automatic road measuring terminal that the embodiment of the invention provides comprises step:
S101, monitor terminal carry out read operation to the journal file of automatic road measuring terminal records, and wherein, said journal file comprises the running information at automatic road measuring terminal;
The running information output at the automatic road measuring terminal that S102, monitor terminal will read from said journal file.
The automatic road measuring terminal can write journal file with the important information that moves automatically in running; Journal file is belonged to catalogue to be shared out; And monitor terminal carries out read operation to journal file, thereby obtains these important informations, on the interface, exports to show.
Preferably, said monitor terminal carries out read operation to the journal file of automatic road measuring terminal records, comprising:
Monitor terminal detects the input/output state sign, and this input/output state sign is used to indicate monitor terminal whether can carry out read operation to the journal file of automatic road measuring terminal records;
Monitor terminal is according to the input/output state sign, and the journal file of automatic road measuring terminal records is carried out read operation.
Input/output state sign (ios::eofbit) described in the embodiment of the invention comprises following four kinds of signs:
Good (good), end (Eofbit), failure (failbit), bad (badbit).
Wherein, if good (good) flag bit is set, explain that then monitor terminal is normal to the read operation of journal file.
Be set if finish (Eofbit) flag bit, explain that then monitor terminal read the ending of journal file, that has promptly read the automatic road measuring terminal writes the journal file place.
If failure (failbit) flag bit is set, then nonfatal I/O mistake has appearred in explanation.
If bad (badbit) flag bit is set, then fatal I/O mistake has appearred in explanation.
Particularly; Write operation is carried out to journal file in the automatic road measuring terminal, and monitor terminal is opened journal file with read-only mode, after monitor terminal opens file; Read file content; If monitor terminal is found the ending sign Eofbit of journal file and has been set that then explanation has been read the automatic road measuring terminal and write daily record place, then waits for a period of time and reads.
Be set if detect Eofbit, then monitor terminal is read process dormancy (Sleep) for a moment, waits for that promptly the automatic road measuring terminal writes process and write new content, afterwards, disposes the Eofbit flag bit, and then reads.
Be not set if detect Eofbit, do not have other input/output error yet, then continue to read the content of journal file.
Promptly; Automatic road measuring terminal and monitor terminal are not to carry out synchronously through the notice of socket or other traditional modes; But through monitor terminal to the detection of input/output state sign (ios::eofbit), judge whether meaningful readable, thereby read and write synchronously.
Preferably, said monitor terminal is according to the input/output state sign, and the journal file of automatic road measuring terminal records is carried out read operation, comprising:
When the journal file end had been read in input/output state sign indication, read operation was carried out to journal file of automatic road measuring terminal records in monitor terminal (for example, representing with T that T can the be 5 seconds) back of waiting for a period of time;
When position, journal file end tail was not read in the indication of input/output state sign, monitor terminal carried out read operation to the journal file of automatic road measuring terminal records.When read the automatic road measuring terminal write daily record place the time, the journal file end has been read in input/output state sign indication.
Further, if the monitor terminal continuous several times detects the state that the input/output state sign is not (good), promptly one or more of following flag bit is set, and then starts wrong detection.
| Eofbit | Arrived end-of-file |
| failbit | Nonfatal I/O mistake |
| badbit | Fatal I/O mistake |
Concrete wrong detection comprises:
Step 1: whether inspection exists network problem, if exist, then can confirm what network failure caused.
About the inspection network problem, for example, can directly call the order of ping, can judgement lead to by ping.
Step 2: whether the inspection share directory exists.
If network is no problem, check then whether share directory exists.
Step 3:, check then whether file exists if share directory exists.
If above three step check tables clear and definite real storages are in fault, can close file, and the prompting concrete detected mistake of user (promptly belonging to any mistake in above-mentioned three steps).Otherwise,, think that then the automatic road measuring terminal does not have writing information for a long time if above-mentioned three steps inspection is all passed through.Monitor terminal Sleep is again removed the input/output state sign after a period of time, and then carries out read operation.
Preferably, said monitor terminal is according to the input/output state sign, and the journal file of automatic road measuring terminal records is carried out read operation, comprising:
In the read operation that the continuous several times monitor terminal carries out the journal file of automatic road measuring terminal records; The input/output state sign is all indicated and has been read the journal file end; Then monitor terminal prolongs stand-by period T; And according to the time waiting after prolonging, the journal file to the automatic road measuring terminal records when the stand-by period finishes carries out read operation;
In the read operation that the continuous several times monitor terminal carries out the journal file of automatic road measuring terminal records; The input/output state sign is all indicated and is not read the journal file end; Then monitor terminal shortens stand-by period T; And according to the time waiting after shortening, the journal file to the automatic road measuring terminal records when the stand-by period finishes carries out read operation.
Monitor terminal is restarted after the automatic road measuring starting terminal, and therefore, when monitor terminal just started, a large amount of daily records had been write at the automatic road measuring terminal.
Therefore, when monitor terminal has just started, read log content, and come out important information in interface display with the fastest speed.This process is called the process that chases after, and promptly monitor terminal is read document location difference bigger of document location and the automatic road measuring terminal written document of file, and therefore, monitor terminal catches up with the fastest speed.
But read the automatic road measuring terminal when writing the position of journal file when monitor terminal, can detect Eofbit and be set, at this moment; Monitor terminal just need slow down speed, reads EOF at every turn, detects the EOF sign and is set; Then,, promptly wait for a period of time with regard to dormancy (Sleep) for a moment; And regulate the speed with degenerative mode, make read or write speed approaching as far as possible, for example:
If read 5 times continuously; All detecting the Eofbit that is eliminated before the read operation has been set again; Show that monitor terminal read 5 times continuously, and the operation that automatic road measuring terminal is not write during this, then one times of the time lengthening of Sleep; But because monitor terminal has the real-time requirement, the time maximum of Sleep is no more than 30 seconds.For example, the initial Sleep time is 5 seconds, if then read continuously 5 times; The Eofbit flag bit has been set before all detecting read operation, and the Sleep time changes 10 seconds into, if read continuously once more 5 times; The Eofbit flag bit has been set before all detecting read operation; The Sleep time changes 20 seconds into, and by that analogy, but the Sleep time the most very much not can be above 30 seconds.
If read all not detect Eofbit behind the character (getchar) for 20 times and be set continuously, perhaps continuous read for 5 times (getline) do not detect Eofbit and is set, and then the time of Sleep is kept to half thely, promptly can quicken to read.For example, the initial Sleep time is 20 seconds, if then read continuously 5 times; The Eofbit flag bit has not been set before all detecting read operation, and the Sleep time changes 10 seconds into, if read continuously once more 5 times; The Eofbit flag bit has not been set before all detecting read operation, and the Sleep time changes 5 seconds into, by that analogy; But Sleep time minimum is 0 second, does not promptly wait for, continuously reads.
Through this degenerative mode, the speed ratio that makes speed that monitor terminal is read and automatic road measuring terminal write is more approaching, both requirement of real time, and the expense to system read-write drops to minimum again.
Preferably; When said monitor terminal carries out read operation to the journal file of automatic road measuring terminal records; When detecting the title of replacing file mark that the current journal file that reads is provided with and new journal file; Close the current journal file that reads,, open new journal file and carry out read operation according to the title of new journal file.
Be the substitute mode that the embodiment of the invention also provides a kind of journal file:
Journal file is write at the automatic road measuring terminal, when the daily record file is too big, for example surpasses 100,000,000, and opening of file can be very inconvenient, needs to change journal file, supposes currently just at usage log file a.log, adopts this moment following steps to carry out journal file and changes:
Step 1: a new journal file is created at the automatic road measuring terminal, at this moment, does not close old journal file.
Step 2: after creating successfully, the automatic road measuring terminal is provided with one and changes file mark at old journal file end, and the title of the new journal file of record plan use, for example, uses<changfile>B.log</changefile>
Step 3: old journal file is closed at the automatic road measuring terminal.
Step 4: monitor terminal is read old journal file end, when detecting the title of changing file mark and new journal file, then closes old journal file (a.log), opens new journal file (b.log).
Preferably, this method also comprises:
Said monitor terminal filters the information of the current journal file that reads, and the information of interface display need be exported in extraction and record.
Preferably, this method also comprises:
When monitor terminal was closed, monitor terminal was noted column information in local profile:
The catalogue at the title of current journal file, the position of reading and current journal file place.
Preferably, said monitor terminal carries out read operation to the journal file of automatic road measuring terminal records, comprising:
If be closed to the process that starts once more from monitor terminal, restart at the automatic road measuring terminal, and then monitor terminal carries out read operation to the journal file of automatic road measuring terminal state-of-the-art record; Otherwise monitor terminal is recorded in the information in the local profile when closing according to monitor terminal, continues the journal file of automatic road measuring terminal records is carried out read operation.
That is to say that the embodiment of the invention is also supported breakpoint transmission, the concrete introduction as follows:
A new logfile directory is created, to preserve the log information file in this running in the automatic road measuring terminal when each the startup.
Monitor terminal is after closing, if has restarted at the automatic road measuring terminal, then the monitor terminal file that only need read under the up-to-date logfile directory gets final product, from first file read under this catalogue to a last file.
But when closing monitor terminal to starting once more in the monitor terminal process, if the automatic road measuring terminal keeps running status always, do not restart, and then began to continue to read file from breakpoint, this process is called breakpoint transmission.
In order to realize breakpoint transmission; Monitor terminal is in running; Need the daily record of record oneself, refine the log information that obtains from the automatic road measuring terminal through filtering, obtain the needed information of interface display; When on the interface, showing, be kept at necessary information in the local log file (like info_backup.txt).Wherein, the information of said necessity for example, comprising: the command interaction between the connection status of parameter configuration, each wireless module, the executing state of test plan, server and the car-mounted terminal, wireless network test daily record etc.
In the embodiment of the invention; Monitor terminal is not to duplicate the daily record at automatic road measuring terminal; But only preserve the information of filtering after refining, and be the needed data of interface display, this has just significantly reduced the canned data amount; And also lowered access time, and the time of reading reprocessing later on.
And when monitor terminal was closed, monitor terminal is record in local profile: the catalogue at the title of current journal file and the position of reading (breakpoint), current journal file place.
When starting monitor terminal once more, whether monitor terminal at first detects the automatic road measuring terminal and restarts.If do not restart, the content that then loads local log file (like info_backup.txt) earlier then according to local profile recorded logs file name and breakpoint, begins to continue to read log information to display interface.If has restarted at the automatic road measuring terminal, then read the journal file that writes down behind the automatic road measuring starting terminal, rather than breakpoint transmission.
Preferably, judge that the method whether the automatic road measuring terminal has carried out restarting comprises:
Can create a Log Directory when automatic road measuring terminal starts at every turn, monitor terminal is the journal file at the breakpoint place that writes down in local profile place catalogue, compares with up-to-date Log Directory under the log folder at automatic road measuring terminal.If inequality, can judge that then the automatic road measuring terminal restarts.If identical, can judge that then the automatic road measuring terminal not restart.
