The fault management function of this software has the four features described below.
Asynchronous fault event monitoring using event notification from devices
This software processes an SNMP Trap from a device and monitoring information from Agent, properly decodes them, and displays them as an asynchronous event.
Since the displayed contents of the event are more detailed and easier to understand than decodes generated by a normal SNMP MIB compiler, they support smooth operation.
The display format (show, hide, display color) for events can be customized in detail by using an XML file. Therefore, operation can be made suitable for the environment used. In addition, fault management of a device not supported by this software is dynamically enabled by adding and editing the XML file.
Since events can be linked to the Systemwalker Centric Manager linkage and Shell files that can be edited as desired by users, operation can be made suitable for the environment used.
See
For details of customization, see "C.6 SNMP Trap XML Definition File".
Fault monitoring using the device polling function (automatic operation by Manager)
The device polling function is a function for this software to observe regularly the state of all devices connected with LAN by using SNMP, ping or unique protocol. When the SNMP Trap from the device cannot be received, the change in the state of the device can be detected and the network error between each device and the administrative server of this software can be detected by this function.
The state change is reflected in the event log and the icon color.
This function is effective to the manual embedded device.
Fault monitoring by checking the current status of devices (manual operation performed by users)
The icon color of a device changes depending on the current status of the device by acquiring latest information.
If a problem occurs, the color of the corresponding category icon or device icon becomes red or yellow. The component with the fault can be identified by placing the device icon appropriately in the Correlation window. (For some faults, however, the icon color of the devices with the faults is not changed, and only events are displayed.)
Fault monitoring by revolving light icon
Revolving light icon lights in red, yellow or green when there is a change in the state of the device.
Click the revolving light icon and select <OK> button of shown dialog. Then, latest information is obtained and the icon color is changed in accordance with the current status of the device (Processing same as above-mentioned "Fault monitoring by checking the current status of devices" is done.)
See
For information about revolving light icon, see "Table 6.2 Revolving light icon state state".
When fault monitoring is begun, fault monitoring is continued only by starting the manager regardless of the operation of the client.
Note
Fault monitoring is done by way of LAN. Fault monitoring can be done only to the device that LAN can connect.
