Description

  The present invention relates to a communication terminal device, a communication system, a communication method, and a program suitable for specifying a cause of failure included in log information accumulated in the device itself.

When a failure occurs in a communication terminal, the log generated in time series in the terminal is accumulated as a log file for the purpose of analyzing the cause. There is already known a method in which a log file stored therein is uploaded to a log server on the service side by a user operation using a log upload function of a communication terminal, and customer support or the like analyzes the log file.
Normally, when a failure occurs, the user contacts the support center by telephone, facsimile, or e-mail, and the support center requests the user to upload the log file in the terminal, and the log after uploading at the support center. The cause of the failure was identified by analyzing the file.
By the way, the log file generated at the communication terminal contains various information such as record information that is not the direct cause of the failure that occurred before the failure occurred, and record information that occurred after the failure occurred until the file upload was completed. Is recorded as a log file.
In particular, if the log upload from the communication terminal failed due to a network failure and the upload succeeded by re-operation after the network is restored, as a log not directly related to the failure that occurred in the communication terminal itself, For example, many error logs related to log uploading are recorded.

Patent Document 1 aims to appropriately extract and store log information differences from log files managed for rotation and generation, without depending on the log format specific to the device outputting the log information. In addition, managing a difference using a hash value is disclosed.
Specifically, in Patent Document 1, a storage unit that stores a reference end and a reference hash value, and one log file from a log file group that is rotation and generation managed are input, and the reference is started from the top of this one log file. Find the hash value up to the end, compare this hash value with the reference hash value, and if they match, extract the log file of the generation after the first log file as the log information difference, if both do not match There is disclosed a log information difference extraction management device including a processing unit that repeats an operation after inputting another log file from a log file group and inputting one log file.

The function of uploading logs from the communication terminal being used by the user to the log server on the service side is normally a function that is used only when a failure occurs. Therefore, in many cases, an error that directly causes a failure that has occurred in the communication terminal itself can be found by analyzing a log file recorded immediately before the log upload point.
However, with the conventional log upload function, even if the log file uploaded from the communication terminal to the log server side is analyzed when the time has elapsed between the time of the failure of the communication terminal itself and the log upload, the log There has been a problem that it is difficult to determine which error information of a plurality of error information recorded in the file is error information indicating the direct cause of the failure that has occurred in the communication terminal.
The present invention has been made in view of the above, and an object of the present invention is to contribute to an improvement in a process for specifying error information indicating a direct cause of a failure included in log information.

  The invention described in claim 1 is a communication terminal device that transmits information to a server via a communication network in order to solve the above-described problem, and the operation content communicated between the other communication terminal device and the own device. Log information creating means for creating log information in time series based on the processing content of the own device and storing the log information in a storage means; and an operation judging means for judging whether or not a predetermined operation is performed when the log information is uploaded. Transmitting means for adding annotation information configured in a predetermined format to a data array of log information acquired from the storage means and transmitting the data to the server via the communication network when the predetermined operation is performed; , Provided.

By performing highlighting using one, it is possible to make it easier to visually check each log level representing the type of log information.

With reference to FIG. 15, the result of the log analysis in sequence S45 shown in FIG. 9 will be described. FIG. 15 is a diagram showing an analysis UI (user interface) screen obtained as a result of log analysis.
In FIG. 15, reference numeral 48 denotes log information immediately before the annotation information 43, and shows an example in which the display color of the log level is changed according to the log level, and particularly an example in which the error log is highlighted. 49 is an example in which the target is the error log immediately before the annotation information 43, and 50 is an example in which the log information after the annotation information 43 is not displayed or deleted.
In this way, among the log information created before the annotation information (annotation information) related to the specified log information, the log information having a predetermined log level is displayed so as to be positioned at the center of the display screen. By doing so, log information having a predetermined log level can be more easily visually confirmed.
In addition, when a deletion instruction is input, log information that is displayed later in time than annotation information (annotation information) related to the specified log information is deleted, so that log information related to the failure Visual confirmation can be facilitated.
Furthermore, by hiding the log information created later in time than the annotation information (annotation information) related to the specified log information, the data arrangement of the log information can be more easily visually confirmed.

As a result, when uploading the log, annotation information indicating that the upload operation has been performed is added to the log information, and when the log information is analyzed, the first error is traced back from where the annotation information was recorded. It can be easily identified that the log was the direct cause of the failure.
For this reason, if a dedicated analysis tool corresponding to annotation information is used, the error status is displayed simply by opening the log information file at the time of analysis, and a quick failure analysis can be performed.
