Your perl/net-snmp environment is damaged. You have mismatched files from

During my previous fiddling around trying to find the root of the problem,
I did copy net-snmp-5.4.2.1/perl/blib/lib/NetSNMP/agent.pm to
/usr/local/lib/perl/5.10.0/NetSNMP/agent.pm.
So now you have one file from 5.4.2.1 and others from 5.4.1. My suggestion
is to stick with 5.4.1 or to make a proper upgrade to 5.4.2.1.
I've reinstalled the 5.4.1 with perl enabled. Now if I'm getting the
following result on haproxy.pl:
$ perl /etc/snmp/haproxy.pl
netsnmp_assert !"registration != duplicate" failed agent_registry.c:535
netsnmp_subtree_load()
netsnmp_assert !"registration != duplicate" failed agent_registry.c:535
netsnmp_subtree_load()
netsnmp_assert !"registration != duplicate" failed agent_registry.c:535
netsnmp_subtree_load()
Warning: no access control information configured.
It's unlikely this agent can serve any useful purpose in this state.
Run "snmpconf -g basic_setup" to help you configure the Haproxy.conf file
for this agent.
I ran snmpconf (answering to the best of my ability) but am still getting the
same results. I actually ended up copying the resulting snmp.conf file to
/etc/snmpd/snmpd.local.conf with the following contents:
proc httpd 1
rwuser ruy auth
rocommunity public rwcommunity public trapcommunity public
authtrapenable 1
disablePerl false
perl do '/etc/snmp/haproxy.pl';
Good. I think we are making a slow progress here.
Syslog shows no errors, and it does show the incoming connection when I do
the snmpbulkwalk. But the result is still:
$ snmpbulkwalk -c public -v2c 127.0.0.1 1.3.6.1.4.1.29385.106.1.0.17
SNMPv2-SMI::enterprises.29385.106.1.0.17 = No more variables left in this MIB
View (It is past the end of the MIB tree)
Did i get the snmpd.conf wrong? Or is there still something else I need to
configure?
First, lets check if haproxy.pl is indeed working: try to walk
"1.3.6.1.4.1.29385.106.2.0".
Then make sure that snmpd/haproxy.pl is able to read the socket provided
by the proxy. By default haproxy.pl expects "/var/run/haproxy.stat", also
make sure that you have valid permissions for the socket.
