This is goign to be a long post I'm afraid - I've been struggling with
this for many hours now.
I'm trying to get systemStats working. I have tried with versions 5.4,
5.4.1, and 5.3.1. The software is running on a custom linux distro, on
kernel 2.6.18. The system is running on Xen. The compile options are:
--enable-mini-agent \
--enable-ucd-snmp-compatibility \
--with-mib-modules="host ucd-snmp/dlmod ucd-snmp/diskio
ip-mib/ipv4InterfaceTable agentx/subagent agentx/master agentx
ucd-snmp/loadave ucd-snmp/memory ucd-snmp/file ucd-snmp/logmatch
ucd-snmp/extensible agent/extend ucd-snmp/pass ucd-snmp/pass_persist
ucd-snmp/proc ucd-snmp/disk" \
--disable-manuals \
--disable-debugging \
--with-default-snmp-version=3 \
--with-sys-contact="[email protected]" \
--with-sys-location="Unknown" \
--enable-shared \
--with-logfile=/var/log/snmpd.log \
--with-persistent-directory="/var/lib/net-snmp" \
--disable-ipv6 --disable-internal-md5 --with-openssl
--without-libwrap --without-rpm --without-bzip2 --without-zlib
--without-elf \
--sysconfdir=/etc
Below is two sets of output, one from my system that isn't working, and
then one from one that is.
