The Enterprise Server MIB
202 Netscape Enterprise Server Administrator’s Guide
Server-initiated communication. The server subagent sends a message or
“trap” to the NMS when a significant event has occurred. For example:
1.
The subagent informs the master agent that the server has stopped.
2.
The master agent sends a message or “trap” reporting the event to the
NMS.
3.
The NMS displays the information textually or graphically through its
network management application.
The Enterprise Server MIB
Each Netscape server has its own management information base (MIB). The
Enterprise Server’s MIB is a file called
netscape-http.mib
. This MIB
contains the definitions for various variables pertaining to network
management for Enterprise Server. These variables are known as managed
objects. Using the Enterprise Server MIB and network management software,
such as HP OpenView, you can monitor your web server like all other devices
on your network.
The Enterprise Server MIB has an object identifier of netscape 1
(
http OBJECT IDENTIFIER : := { netscape 1 }
) and is located in
the
server_root /plugins/snmp
directory.
You can see administrative information about your web server and monitor the
server in real time using the Enterprise Server MIB. Table 9.1 lists and describes
the managed objects stored in the
netscape-http.mib
.
