## Abstract

The present disclosure relates to a log data processing apparatus and a method for controlling the same. A log data processing apparatus according to an embodiment includes a communication unit configured to receive information on log data corresponding to an application from a device for generating the log data, a control unit configured to generate a log message on a basis of the log data information, and a storage unit configured to store the log message and generation history information of the log message generated, wherein the log data information includes a log message parameter, message code information, and identifier information of the application.

## Claims

### Claim 1

A log data processing system comprising:
a log data generation device configured to execute an application and generate log data corresponding to the executed application; and
a log data processing server configured to generate and store a log data message based on the generated log data, the log data processing server comprising:
a communication unit configured to receive log data information related to the generated log data from the log data generation device;
a control unit comprising a log message generation unit configured to generate a log message based on the received log data information; and
a storage unit configured to store the generated log message and generation history information of the generated log message,
wherein the log data information comprises a log message parameter, message code information, and identifier information of the executed application, and
wherein the log message generation unit generates a level character string and level information of the log data based on the message code information.

### Claim 2 (depends on 1)

The log data processing system according to claim 1, wherein the generated log message comprises the generated level character string and the generated message character string based on the received log data information.

### Claim 3 (depends on 1)

The log data processing system according to claim 1, wherein the storage unit comprises:
a history storage unit configured to store the generation history information; and
a data storage unit configured to store the generated log message.

### Claim 4 (depends on 1)

The log data processing system according to claim 1, further comprising a log viewer configured to output the generated log message based on the received log data information.

### Claim 5 (depends on 1)

The log data processing system according to claim 1, wherein the log data generation device is a supervisory control device.
