Monitoring Dell Boxes via SNMP (CentOS 5.1 x86)

[Kaj Niemi]

Hi,


As you are running CentOS you could consider upgrading to net-snmp  
5.4.1 (the rpm from fc8 or so will work fine as long as you rebuild  
it). It fixes pretty much all issues I've had with Xen and net-snmp  
working together. The default net-snmps from RedHat, due to various  
reasons, are not really good (RHEL4 is still missing 64 bit interface  
counters, etc.) for serious production use. The OMSAs will work okay  
with later net-snmp versions and so do HP ASM SNMP daemons, too.
