Part of a private discussion I'm bumping back to -coders 'cause I think
he found a bug.

I've upgraded my Solaris snmpd to Net-SNMP 5.4.  Here's what I'm
seeing now.  First, on the Solaris host:

   [EMAIL PROTECTED]: sbin/ [1] # df -h /export
   Filesystem             size   used  avail capacity  Mounted on
   Export                 1.2T   3.8G   1.1T     1%    /export

Now, with the same Net-SNMP 5.4 build on the same host, I walk the
hrStorage MIB and get:

HOST-RESOURCES-MIB::hrStorageIndex.36 = INTEGER: 36
HOST-RESOURCES-MIB::hrStorageType.36 = OID:
HOST-RESOURCES-TYPES::hrStorageFixedDisk
HOST-RESOURCES-MIB::hrStorageDescr.36 = STRING: /export
HOST-RESOURCES-MIB::hrStorageAllocationUnits.36 = INTEGER: 512 Bytes
HOST-RESOURCES-MIB::hrStorageSize.36 = INTEGER: -2001010982
HOST-RESOURCES-MIB::hrStorageUsed.36 = INTEGER: 8065283
HOST-RESOURCES-MIB::hrStorageAllocationFailures.36 = Counter32: 0

Note the negative number for hrStorageSize.36

I tried walking dskTable, but it says "no such object", which is strange
because on my test machine, running the same snmpd binary,  but without
 the giant ZFS filesystem, dskTable works fine.

Here's the build info:

UCD-SNMP-MIB::versionConfigureOptions.0 = STRING:
'--prefix=/pkg/net-snmp-5.4-SunOS-5.10' '--with-default-snmp-version=3'
'--enable-developer=yes' '--with-libs=-ldl' '--datadir=/etc/sma'
'--with-mibdirs=/etc/sma/snmp/mibs' '--enable-agentx-dom-sock-only'
'--with-mib-modules=host disman/event-mib ucd-snmp/diskio ucd-snmp/disk
ucd-snmp/errormib ucd-snmp/proc' '--sysconfdir=/etc' '--with-zlib'
'--with-libwrap' '--with-openssl=/usr/local/ssl' '--with-pic'
'--enable-shared=no' '--localstatedir=/etc' '--without-logfile'
'--with-sys-contact=Knowledgable Solar Frog' '--with-sys-location=On a
Super Micro thingie' '--with-persistent-directory=/var/sma_snmp'
'--with-dummy-values' 'CC=/usr/local/bin/gcc'
'LDFLAGS=-R/usr/local/ssl/lib/'

My /usr/local/bin/gcc and SSL is all from the SMC packages.
