When the dial tone is detected in step S20, basic data such as the type of modem and the type of line are collected and stored as a log (step S30).

Then, by checking the dial-up indicating that a call is being made, information about the cause of failure is collected through the TAPI information collector 110 and stored as a log (step S44).

In addition, when dialing is normally performed, the telephone number information of the server currently making the call is collected and stored as a log (step S50). To collect this information, all the data sent and received between the modem and the application program is monitored to extract the phone number information.

Subsequently, by checking whether the modem is connected (step S60), when the modem is not connected, the connection failure cause information is collected through the TAPI information collector 110, and the collected connection failure cause information is stored as a log ( Step S64).

In addition, when the modem is checked to be connected, modem connection speed information is collected and stored as a log (step S70). In other words, if dialing continues and the server side receives a call, a connection signal is detected. If a connection failure is detected, it immediately collects information on the cause of the failure, and if the connection is successful, the connection speed of the current modem Collect information.

When the connection on the line is completed, the user authentication is checked to access the network server (step S80). If authentication fails, the authentication failure information is collected through the RAS information collector 140 and left in the log (step S84). ).

If the user authentication is successful, the user name currently used for authentication is collected, and the total time required for authentication is calculated and left in the log (step S90).

Subsequently, by checking the RAS connection state (step S100), if the RAS is not connected, the RAS connection failure information is collected through the RAS information collector 140, and the collected RAS connection failure information is left in the log (step S104).

If it is checked in step S100 that the connection is a RAS connection, the presence or absence of a log record for the previous communication network connection is checked, and if there is a log record, the data is transmitted to the server (step S120). If information is detected and there is no log record for the communication network connection in step S110, the connection state is monitored and communication speed information is collected and the collected communication speed information is left in the log (step S130).

After the network connection is completed, all the information generated while using the network is collected and left in the log.When the user terminates the connection, the connection termination information is collected through the TAPI information collector 110 and the collected connection termination information is left in the log. (Step S140).
