we use snmpd for getting stats for cacti. Most stats are created via Universal Log Analyser


For Debian and derivatives the server package mentioned above is snmpd. In most cases you will also want client / admin tools which are in the snmp package.

Now that will get you a basically functioning service, but since MIBs are can't be distributed due to licensing, they can't be part of the "open" packages Debian ships and since I originally wrote this article they have been removed. This means that things that are taken for granted here won't actually work unless you install the snmp-mibs-downloader package as well. This will pull in all the necessary MIBs in place, but to actually use them you will need to look in /etc/snmp/snmp.conf and see the comment there.

By default use of MIBs is disabled so you will need to comment the line as described in the file to enable use of the MIBs.

#  Walk the NET-SNMP-EXTEND-MIB tables (nsExtendConfigTable, nsExtendOutput1Table
#     and nsExtendOutput2Table) to see the resulting output

#  Note that the "extend" directive supercedes the previous "exec" and "sh" directives
#  However, walking the UCD-SNMP-MIB::extTable should still returns the same output,
#     as well as the fuller results in the above tables.
