In the related, in the process be optimized for system (such as android system), in the normal situation of every system index, usually need to find out the process that current system takies IO (InputOutput input and output) most.But current system does not provide the implementation method monitored simply and easily and take the too high process of IO in current system.
In view of this, the disclosure proposes a kind of process lookup method, carries the process daily record of predetermined keyword in the process daily record by each process in retrieval preset time period; Described predetermined keyword characterizes current process and takies IO resource; The journal entries identical for process number in the described process daily record retrieved is carried out quantity statistics and counts; Searching the maximum process number of described counting as taking the maximum process number of IO resource in described preset time period, can be implemented as user and searching in current system and take the highest process of IO resource, thus provide foundation for the system optimization of user.
As shown in Figure 1, Fig. 1 is a kind of process lookup method according to an exemplary embodiment, and this process lookup method is used for, in client, comprising the following steps:
In a step 101, the process daily record of carrying predetermined keyword in the process daily record of each process in preset time period is retrieved; Described predetermined keyword characterizes current process and takies IO resource;
In a step 102, carry out quantity statistics for the journal entries that process number in the described process daily record retrieved is identical and count;
In step 103, the maximum process number of described counting is searched as taking the maximum process number of IO resource in described preset time period.
Above-mentioned client can comprise system-oriented maintainer provides process to search the client software of service; Such as, for Android system, this client software can be provide process to search the lookup tool of service towards Android system maintainer, and developer can be searched by this lookup tool and currently in Android system take the maximum process of IO resource.
Wherein, carry the hardware environment of above-mentioned client software, be not particularly limited in the present embodiment; Such as, can be PC main frame, mobile terminal or server.
In the present embodiment, system maintenance personnel, in the process be optimized system, often need every operating index of the system of checking, the CPU usage of such as system, memory consumption rate etc.But, in actual applications, system cloud gray model slowly bottleneck often all because some process takies, IO resource is too high to be caused, therefore currently in seeking system take the highest process of IO resource, what the optimization for system just became being extremely necessary.
At present, system maintenance personnel, when needs seeking system process, are by using the system tools such as such as blockdump usually, specifically export that order come at blockdump interface inediting.When after the output order that blockdump tool detection is edited to user, then in interface, the journal file (log file) of each process run current in system can be exported to system maintenance personnel in interface.
Such as, for blockdump instrument, system maintenance personnel in the interface inediting dmesg order of blockdump instrument, can trigger the log file of the current each process of blockdump instrument output system usually.
But, system maintenance personnel are by using the system tools such as blockdump, although the journal file of each process in system can be checked very easily, then the system tool such as existing such as blockdump does not provide the current function taking the highest process of IO in seeking system, therefore when system maintenance personnel need to be optimized system, the journal file that the analysis blockdump instrument of having to one by one manual exports.
In the present embodiment, for solving the problem, can introduce in existing blockdump instrument and search logic shown by above-mentioned steps 101 to step 103, existing blockdump instrument is made to have current this New function taking the highest process of IO resource in seeking system, thus system maintenance personnel can use blockdump instrument to find out efficiently currently in system takies the highest process of IO resource, for system optimization provides foundation.
Be that the blockdump instrument with the process function that the current IO of taking resource is the highest in seeking system is described for above-mentioned client software below.
Certainly, be that the blockdump instrument of the function with the highest process of the current IO of taking resource in seeking system is only exemplary illustration above for above-mentioned client software, in actual applications, also can search to step 103 system tool that logic development makes new advances based on step 101.That is, above-mentioned client software can be have the current existing system instrument taking this New function of the highest process of IO resource in seeking system, also can be the new system tool again developed.
In an initial condition, when system maintenance personnel need to search sometime in section, the process of IO resource is taken most in system, blockdump instrument can be run, in the interface inediting dmesg order of blockdump instrument, trigger the log file of the current each process of blockdump instrument output system.
Wherein, the above-mentioned time period can by the self-defined setting of system maintenance personnel.
When realizing, system-oriented maintainer one can be provided for arranging the user option of above-mentioned time period in blockdump instrument, system maintenance personnel can arrange the default time period in this user option, after the time period that this is preset is provided with, now blockdump instrument can run above-mentioned search logic to search this preset time period in, take the process of IO resource in system most.
Such as, suppose that the above-mentioned preset time period that user is arranged is 30 minutes, so blockdump instrument can run and above-mentionedly search logic to search, and to after 30 minutes from current time, takies the process of IO resource in system most.
In the present embodiment, after the log file of the current each process of output system, now blockdump instrument can obtain the above-mentioned default time period that user is arranged on backstage, from the log file exported, then read the log file of each process in this preset time period.
Such as, still suppose that the above-mentioned preset time period that user is arranged is 30 minutes, so blockdump instrument can, the log file of backstage from each process exported, read from current time, the log file of each process within 30 minutes.
After blockdump instrument reads the log file of each process within the above-mentioned default time period, now blockdump instrument can in these log files read, and the log file of predetermined keyword is carried in retrieval.Wherein, this predetermined keyword can characterize current process and take IO resource, and namely this predetermined keyword can comprise the keyword that those sign current process take IO resource.
For blockdump instrument, generally include process number in the log file exported, the information such as action, filename, disk name and implementor name that No. Inode (inode number of reading and writing data), this process perform, and the action that this process of carrying in this log file performs usually can characterize this process and whether taking IO resource.Such as, in the log file that process generates when taking IO resource, usually the actions such as READ, WRITE and dirtied can be comprised, READ represents that current process take part in digital independent, WRITE represents that current process take part in data write, and dirtied then represents that current process take part in write back data.
Therefore, in actual applications, above-mentioned can characterize that predetermined keyword that current process takies IO resource then can comprise in the keywords such as READ, WRITE and dirtied one or more.Blockdump instrument is in the log file from each process in the above-mentioned default time period read, when the log file of predetermined keyword is carried in retrieval, the log file carrying the keywords such as READ, WRITE and dirtied in the log file read can be retrieved.
In the present embodiment, after blockdump instrument retrieves the log file carrying above-mentioned predetermined keyword, owing to also may comprise some invalid log files in these log files, therefore blockdump instrument can also remove the invalid log file in these log files retrieved based on preset strategy.
Wherein, in blockdump instrument, the log file generated when process takies IO resource only comprises letter usually, and there is not the character of non-letter, if comprise the character of non-letter in the log file that therefore blockdump instrument retrieves, so this log file is probably invalid log file.
Therefore, in a kind of embodiment illustrated, above-mentioned preset strategy can comprise: travel through the log file retrieved, and screens the log entry of carrying non-alphabetic characters in the log file retrieved, then the log entry of carrying non-alphabetic characters filtered out is removed as invalid log file.
Visible, in this way, effectively can remove the invalid log file in the log file retrieved, thus when the follow-up log file to retrieving carries out quantity statistics to search taking the highest process of IO resource, can avoid because invalid log file causes interference to final lookup result, and the situation that the lookup result caused is undesirable.
In the present embodiment, due to usually can process number be comprised in log file, and some processes take IO resource more time, the log file comprising the process number of this process in these log files that blockdump instrument retrieves is also more.
Therefore, when after the invalid log file that blockdump instrument to remove based on preset strategy in the log file retrieved, blockdump instrument can carry out quantity statistics for the log entry that process number in these log files retrieved is identical and counts, and search the maximum process number of counting as taking the maximum process number of IO resource in preset time period, then process number maximum for the counting found is exported.This process number now exported then takies the maximum process number of IO resource in preset time period.
Wherein, when the log entry that blockdump instrument process number in for these log files retrieved is identical is carried out quantity statistics and counts, can sort to these log files retrieved based on process number, then carry out quantity statistics for the log entry that process number in these log files after sequence is identical and count.In this way, the complexity of blockdump instrument when carrying out quantity statistics can be reduced.
Blockdump, when being exported by process number maximum for counting, can export one and also can export multiple.Namely blockdump is when output process, and a process number that can be maximum by the counting counted exports to system maintenance personnel, also can export to system maintenance personnel by multiple process number that the counting counted is maximum.
In addition, blockdump is when exporting process number maximum for counting, and the number of the concrete process number exported also can be set based on the demand of reality by system maintenance personnel.
Such as, system maintenance personnel are when carrying out system optimization, if the running status of current system still can, now system maintenance personnel may only need be optimized for the process taking IO the highest, and now the number of the process number of above-mentioned output can be set to 1 by system maintenance personnel.If the operation of current system is slow, now system maintenance personnel may need to be optimized for taking IO the most much higher process, and now the number of the process number of above-mentioned output can be set to multiple by system maintenance personnel.
In the present embodiment, count value maximum for counting except can except the maximum process number of counting exports to system maintenance personnel, can also carry out associating with above-mentioned process number and exports by blockdump.Wherein, blockdump count the maximum count value process number maximum with above-mentioned counting associate export time, still can export one and also can export multiple.
Such as, suppose that log entry that blockdump is identical to process number in the log file retrieved draws after carrying out quantity statistics, in these log files, the maximum count of the log entry that process number is identical is 100, corresponding same process number is 1, so this process number 1 can be taken the maximum process number of IO resource and exports to system maintenance personnel by blockdump in preset time period, simultaneously by the maximum count 100 of this process number 1 correspondence, to associate with this process number 1 as the IO resource occupation quantity of this process and export.Thus system maintenance personnel, by checking the content that blockdump exports, both can recognize the current process number taking IO resource most, the IO resource quantity that this process specifically takies also can be recognized.
Visible, in this way, system maintenance personnel can use blockdump instrument to find out efficiently and currently in system take the highest process of IO resource, for system optimization provides foundation.
After blockdump to output to system maintenance personnel take the IO resource occupation quantity of the maximum process number of IO resource and association within the time period of presetting, now system maintenance personnel using the content of blockdump output as the foundation of system optimization, can be optimized system.Such as, if the current operation of system is slow, system maintenance personnel can select to terminate currently to take one or more the highest process of IO resource, reach the object of system optimization with the processing pressure of delivery system.
In the embodiment above, the process daily record of predetermined keyword is carried in the process daily record by each process in retrieval preset time period; Described predetermined keyword characterizes current process and takies IO resource; The journal entries identical for process number in the described process daily record retrieved is carried out quantity statistics and counts; Searching the maximum process number of described counting as taking the maximum process number of IO resource in described preset time period, can be implemented as user and searching in current system and take the highest process of IO resource, thus provide foundation for the system optimization of user.
As shown in Figure 2, Fig. 2 is the another kind of process lookup method according to an exemplary embodiment, and this process lookup method is used for, in client, said method comprising the steps of:
In step 201, the order inputted based on user exports the process daily record of each process;
In step 202., the preset time period that user is arranged is obtained;
In step 203, from the process daily record exported, read the process daily record of each process in described preset time period;
In step 204, the process daily record of carrying predetermined keyword in the process daily record of each process in preset time period is retrieved; Described predetermined keyword characterizes current process and takies IO resource;
In step 205, based on process number, the described process daily record retrieved is sorted;
In step 206, carry out quantity statistics for the journal entries that process number in the described process daily record after sequence is identical and count;
In step 207, search the maximum process number of described counting as taking the maximum process number of IO resource in described preset time period, and the process number that process number maximum for described counting takies IO resource maximum in described preset time period is exported to user, and count value maximum for described counting is associated as the process number that IO resource occupation quantity is maximum with described counting export.
Above-mentioned client can comprise system-oriented maintainer provides process to search the client software of service; Such as, for Android system, this client software can be provide process to search the lookup tool of service towards Android system maintainer, and developer can be searched by this lookup tool and currently in Android system take the maximum process of IO resource.
Wherein, carry the hardware environment of above-mentioned client software, be not particularly limited in the present embodiment; Such as, can be PC main frame, mobile terminal or server.
In the present embodiment, system maintenance personnel, in the process be optimized system, often need every operating index of the system of checking, the CPU usage of such as system, memory consumption rate etc.But, in actual applications, system cloud gray model slowly bottleneck often all because some process takies, IO resource is too high to be caused, therefore currently in seeking system take the highest process of IO resource, what the optimization for system just became being extremely necessary.
