The fault management function of this software has the three features described below.
The fault management function starts monitoring through the registration of the target device to the manager and continues monitoring processing while the manager is running.
Point
"Device status" indicates the total status of the device.
Note
Fault monitoring is performed via LAN. As such, it is not possible to perform fault monitoring for devices which cannot be connected by LAN.
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) 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
Refer to "A.5 SNMP Trap XML Definition File" for details of customization.
Fault Monitoring Using 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 Management 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 Current Status of Devices
For devices that support automatic updates of the device component status, this product acquires the device status and device component status automatically from the device. For this reason, no operation is required to acquire the latest status information of the device. For devices that support automatic updates of the device component status, refer to "2.5 Monitoring Device Component Status".
For devices that do not support automatic updates of the device component status, this product acquires the device status automatically from the device, but does not acquire the device component status automatically. To check the latest device component status, operation is required to acquire the latest status information of the device. Performing operation to acquire the latest status information changes the device component status from the current status.
If a problem occurs, a device status changes the display corresponding to its status.
