Configuring ITO
Preconfigured Elements
memory usage, adapters and network interfaces, disks and disk
controllers, volumes, queues, users, connections, open files, and installed
software.
For print servers, NMA 2.1 or later provides additional queue
information that is not available for servers running the older version of
NMA.
NMA 2.1 Agent
The NMA provides real-time server performance data about the
NetWare server alarms that can either be sent to the network and
system management consoles or be locally processed by the ITO agent
and then forwarded to the ITO management console.
The NMA 2.1 agent is a set of NetWare agent NLMs that must be
deployed on each NetWare server that you want to manage from the ITO
console or Novell ManageWise console. The NetWare agent NLMs are:
❏ NWTRAP.NLM - 400+ traps with Novell NetExpert help text
❏ HOSTMIB.NLM - NetWare Server SNMP Host Resources MIB
❏ SERVINST.NLM - NetWare Server SNMP instrumentation
❏ NTREND.NLM - NetWare Server server based trending
All NetWare servers from Novell are supported by NMA including all 3.x
and 4.x NetWare servers, SFT III servers, SMP servers, and Mirrored
Servers. These agents are all provided and supported by Novell and can
be purchased as a separate Part No. from the Novell ManageWise
console.
Performance Monitoring
Novell NMA 2.1 Agent NLMs enable you to monitor performance
statistics such as CPU utilization, the number of users and connections,
as well as memory and disk usage (including permanent and allocated
memory, and dirty and allocated cache buffers).
Server faults are managed by monitoring the server’s key parameters.
These conditions are monitored directly at the server and then passed to
the ITO agent via SNMP traps.
