Hi everyone,

I'm starting the deployment (planning the deployment to be more
accurate) of Tivoli Netview in an mixed environment of Linux, OpenBSD
and Windows servers, Cisco routers and switches, and RadioFrequency
terminals and antennas.

Due my lack of expertise with "true" NMS's, I'm trying to reach with
Netview the same level of functionality that Nagios has given us by
now, and in subsequent iterations I'll explore all the power of

So, I have installed Tivoli Netview on an Suse Linux Enterprise Server
9, readed (most of) the Unix Administrator's guide and done some basic

Just now I'm trying to get notifications of high levels of load and
disk usage. Theorically, doesn't seem too difficult. I've added this
expression on mibExpr.conf

HDiskUtil \
"(hrStorageUsed / hrStorageSize) * 100"  \
        . \
        . / \
        100 *

and using the Motif GUI, this to snmpCol.conf

MIB HDiskUtil HDiskUtil units EXPRESSION R
O Servidores_windows 60 90.000000 90.000000 A s 58720263 LIST 0

This doesn't work on Windows boxes and don't know why. But, it's
worse. Linux and OpenBSD boxes doesn't have hrStorageUsed at all on
their mib-2 tree. To get diskusage relevant OID's I have to look under

So, I'm a bit disoriented, Which is the "standard" way of deal with
net-snmp and Window implementations?. I'm specially interested on get
notifications of load, disk usage, and vital processes liveness.

Sorry if my question is too simplistic. I'll read any documentation
you point me at. I'm avid of detailed docs.

Thanks in advance,
