5.2Status Indication in the Map
5.2.1The Status from the Viewpoint of NetView
NetView determines the status of a device in the map by sending ICMP echo requests to the respective device. The status determined by this method only indicates the accessibility state of the device. To present the ServerView status described below, the Map application creates a ServerView component symbol in the submap of the server.
NetView determines the status of a correctly configured Fujitsu Siemens server from the status of all its component symbols (attribute Status Source of the symbol equals Propagated), e.g., from the ServerView status and the status of all interfaces.
IThe ServerView status can be determined only if the server is accessible via SNMP. If it is not, the status of the ServerView component symbol is no longer updated. The server is then monitored by NetView's monitoring of the other components.
VWarning
If the monitoring for the other components of a server by NetView is disabled, it is possible that a failure of that server may not be reflected by a status change of the corresponding symbol in the NetView map. This could occur, for example, if the submap of the server contains only the ServerView symbol and a symbol for the interface, and the user deletes the interface symbol or sets this interface component object to unmanaged.
5.2.2The ServerView Status
For Fujitsu Siemens servers with installed ServerView subagents, you can obtain more detailed information on the status of the device than just its avail- ability status. For this reason, the sniInvCondition object from the INVENTORY- MIB depicts the overall status of all ServerView agents on the relevant device. The status returned is always the most critical state among all the ServerView agents.
By monitoring these MIB variables, you can therefore determine the status of a device from the viewpoint of ServerView.
