An example of collecting message logs at the time will be described.

Communication network equipment management operation system 3
00 sets the importance of the message as a condition of the message to be notified in real time at normal times. That is,
The message notification condition generation unit 311 generates a condition that sets a high degree of importance, which is a level at which the maintenance person must immediately take action. The generated condition is edited by the command editing unit 307 into a transmission format to the communication network equipment 200, and is transmitted from the command transmission unit 308 to the corresponding communication network equipment 200.

When the communication network equipment 200 receives the message notification condition setting command from the communication network equipment management operation system 300, the command analysis section 202 analyzes the command contents and decides to start the message notification condition setting processing. To do. In the command execution unit 203, the message notification condition included as a command parameter, in this embodiment, the importance of the message to be notified is set in the message notification condition management table 213. Then, the response message generation unit 204 and the editing unit 205 generate the command execution result and edit the transmission format for the communication network facility management operation system 300, respectively, and send the response message from the message transmission unit 212.

In the communication network equipment 200, when the failure detection unit 206 detects a failure, the failure processing unit 207 executes failure processing such as disconnection of the failed device, and the message generation unit 208 performs the device name and the failure content. , A message including the degree of importance is generated, and the generated message is stored in the message log 214 in the message storage unit 209.
