The present invention has been made in view of the above, and an object thereof is to optimize the amount of communication and transmission time associated with uploading.

  In order to solve the above-described problem, the invention described in claim 1 is based on operation contents communicated between another communication terminal apparatus and the own apparatus via a communication network, and processing contents of the own apparatus. A communication terminal device comprising log information creation means for creating log information in time series and storing the log information in a storage means, and uploading the log information to a server via the communication network, corresponding to an input received from a user Operation determining means for determining whether or not the operation is an operation to be performed when uploading the log information to the server, and when there is the operation, a log divided into levels according to the failure content included in the log information Based on log parameter information transmitting means for transmitting parameter information to the server and log request information transmitted by the server that has received the log parameter information, And control means for controlling so as to upload the log information to the server relating to the failure content levels log parameter information specified is represented by Kutomo the log request information, characterized in that it comprises a.

  According to the present invention, prior to the execution of the log upload process, by limiting the size of the log file in accordance with the level according to the failure content of the log file, the traffic and transmission time associated with the upload can be optimized. Can do.

FIG. 10 is a sequence diagram when log upload from the communication terminal to the log upload server 50 is successful in the communication system 1 according to the embodiment of the present invention.
First, it is assumed that a communication conference is being performed between the communication terminal 10 and another communication terminal 10 via the communication network 2 (S5). At this time, in the communication terminal 10, the log information creation unit 20 accumulates the log file 1001 storing the created log information in the storage unit 1000 (S7).
Here, it is assumed that a failure has occurred in the communication terminal 10 for some reason when a communication conference is being performed between the communication terminal 10 and another communication terminal 10. At this time, the user reports to the support center that there is a failure in the communication terminal 10 using, for example, a telephone, e-mail, or communication conference (S10).
At this time, on the support center side, the person in charge receiving the trouble report from the user requests the user to operate the log upload function provided in the communication terminal 10 in order to analyze the log file stored in the communication terminal 10 ( S15).

At this time, the user operates the log upload function provided in the communication terminal 10 (S20). At this time, the operation determination unit 23 determines whether or not the operation corresponding to the input received from the user is an operation performed when the log information is uploaded to the log upload server 50. That is, the operation determination unit 23 determines the operation of the transmission button on the UI screen.
Next, in response to the ON operation of the transmission button of the log upload function, the log transmission control unit 22 collects the log information stored in the log file from the storage unit 1000 and creates the log parameter information 3000. The log parameter information is information classified into levels according to the degree of urgency regarding the log information. As the log parameter information, it is possible to use at least one information of a size related to the entire log information, a size for each different log level, an acquisition start time and an acquisition end time related to the log information.

FIG. 11 shows an example of the log parameter information 3000. The log parameter information 3000 is created in the JSON format. In the “total” parameter of the log parameter information 3000, the entire size (unit: bytes) of the log file is recorded. In the “level” parameter, a list of sizes for each log file is recorded in units of bytes.
The “level” parameter is classified according to the content of the failure included in the log information, “fat” indicating a fatal error, “error” indicating a normal error, “warn” indicating a warning, tracking The information is recorded by being divided into sizes for each log level including “trace” representing possible information.
In the “time” parameter, an acquisition start time and an acquisition end time of the log information are recorded. “Since” in the “time” parameter is an acquisition start time, and “to” is an acquisition end time. These parameters can be arbitrarily determined according to the log level implementation.
In the communication terminal 10, the transmission / reception unit 11 transmits the log parameter information 3000 created by the log transmission control unit 22 to the log upload server 50 (S21).

The log upload server 50 stores the log parameter information 3000 received from the communication terminal 10 in the storage unit 5000.
The log information extraction unit 511 of the log upload server 50 extracts parameters that need to be analyzed from the log parameter information 3000 stored in the storage unit 5000 and performs syntax analysis of the extracted parameters. A schedule plan for performing the analysis process is created from the parameter having the highest level, and log request information 3100 including a parameter of a level necessary for the analysis process is generated and transmitted to the communication terminal 10 as the log request information 3100 (S22).
The parameter extraction processing in the log upload server 50 is performed based on the storage capacity of the log upload server 50 (the storage area capacity allocated to the user) or a preset program.

With reference to FIG. 12, an example of the log request information 3100 generated by the log upload server 50 will be described.
The log request information 3100 is created in the JSON format. In the “level” item, the log level of the log information requesting transmission from the communication terminal 10 is specified by an array.
In this embodiment, log levels of “fatal” and “error” are specified. If the log request information 3100 does not specify all log levels, all log levels are specified. In the item “time”, a time range of log information for which transmission is requested is designated. “Since” is an acquisition start time requested, and “to” is an acquisition end time requested. If no time range is specified, all time ranges are specified.
In the log request information 3100 of this embodiment, the logs of “fatal” and “error” acquired between the time “2015-01-10T00: 00: 00Z” and the time “2015-01-20T00: 00: 00Z”. Level log information is requested as log request information 3100. If neither the log level nor the time range is specified, all log information becomes the log request information 3100.

Next, the transmission / reception unit 11 of the communication terminal 10 receives the log request information 3100 from the log upload server 50.
Next, the log information collection / compression unit 24 of the communication terminal 10 collects the log file 1001 related to the failure content at the level indicated by the log parameter information specified by the log request information 3100 and performs data compression processing.
The log file 1001 is accumulated in the storage unit 1000, and the log information collection / compression unit 24 collects log information of the log file related to the failure content of the level indicated by the log parameter information specified by the log request information 3100 from the recording unit 1000. Then, a data compression process is performed, and a compressed log file is generated and stored in the storage unit 1000.

For example, as shown in FIG. 12, when the log level of “fatal” and “error” is specified in the log request information 3100, the log information of the log file of the log level of “fatal” and “error” is displayed. Data is collected from the recording unit 1000 and subjected to data compression processing, and a compressed log file is generated and stored in the storage unit 1000.
Next, the log transmission control unit 22 acquires the log file specified by the log request information 3100 from the storage unit 1000, adds annotation information (annotation information) configured in a predetermined format to the data array, and adds the communication network 2 To the log upload server 50 (S30).

Here, when the communication network 2 provided between the communication terminal 10 and the log upload server 50 is normally connected, the user can achieve uploading with a single operation.
In accordance come technology, the size of the log file 1001 is a 1MB about several 100KB example, it varies depending on the operating status of each communication terminal 10. According to the prior art, the time required for uploading varies depending on the network status and the size of the log file, but is completed in about 1 to 3 seconds, for example.
On the other hand, in this embodiment, it is not necessary to upload all log information. That is, the log information of the log file having the log level of “fatal” or “error” may be uploaded to the log upload server 50 according to the log request information 3100, for example. For this reason, it is possible to optimize the communication amount and transmission time associated with the upload, and to reduce the load on the storage capacity of the log upload server 50 and the load on the network.
In sequence S <b> 30, when the session from the communication terminal 10 to the log upload server 50 is established via the communication network 2 and the upload from the communication terminal 10 to the log upload server 50 is successful, the log transmission control unit 22 The function notifies the user of a success notification (S35).

On the other hand, the log upload server 50 stores the log file 1001 uploaded from the communication terminal 10 in the storage unit 5500 (S40).
Here, when the log upload is completed, the operator may be notified from the log upload server 50 that the upload of the new log file is completed.
At this time, information that allows the operator of the support center to determine from which communication terminal the log is uploaded, such as the terminal name and terminal ID of the communication terminal 10 that uploaded the log, may also be notified.
Further, when the notification displayed on the display 208 is clicked, the analysis processing by the log analysis processing unit 512 may be automatically started.
In the support center, communication with the log upload server 50 is started using the communication terminal 30, and the log file 1001 uploaded to the log upload server 50 is read from the storage unit 5500 and displayed on the display of the communication terminal 30. Then, an analysis request is output to the log upload server 50, the log upload server 50 is made to analyze the log file 1001, and the cause of the failure is investigated (S45).

FIG. 13 is a sequence diagram when log upload from the communication terminal to the log upload server 50 fails in the communication system 1 according to the embodiment of the present invention. In addition, since the code | symbol shown in FIG. 13 and the code | symbol same as FIG. 10 is the same structure, the description is abbreviate | omitted.
The log transmission control unit 22 attempts to upload the compressed log file to the log upload server 50 but fails (S30).
The communication terminal 10 notifies the user of an upload failure notification (S35).

  As described above, prior to uploading the log information to the log upload server 50, the log parameter information 3000 classified according to the failure contents included in the log information is transmitted to the log upload server 50, and this log parameter information After extracting the parameters to be analyzed from 3000, the log request information 3100 is transmitted to the communication terminal 10, and the log information related to the failure content at the level indicated by the log parameter information designated by the log request information 3100 is sent to the log upload server 50. Since uploading, log information necessary for analysis can be transmitted, and it is not necessary to upload all log information. For this reason, it is possible to optimize the communication amount and transmission time associated with the upload, and to reduce the load on the storage capacity of the log upload server 50 and the load on the network.
