Hi,

I've been trying to get SNMP monitoring to work for the last few days and have had quite a hard time getting it up. I am quite new to Linux, load balancing and SNMP so please take it easy on me.

I am running Ubuntu 8.10, Haproxy 1.3.15.7 and I have just compiled net-snmp 5.4.2.1 with perl enabled (tried configuring with both v3 and v2c without success). I have copied haproxy.pl to /etc/snmp/haproxy and I modified /etc/snmp/snmpd.conf to include the lines indicated in the netsnmp-perl README.

However, when I run:

$ sudo snmpbulkwalk -c public -v2c 127.0.0.1 1.3.6.1.4.1.29385.106 SNMPv2-SMI::enterprises.29385.106 = No more variables left in this MIB View (It is past the end of the MIB tree)

Digging through forums I thought what I needed was to add a 'stats socket /var/run/haproxy.stat mod 777' line to my haproxy config, but when I add this, I get the following error:

[ALERT] 032/163027 (24099) : parsing [/etc/haproxy/haproxy.cfg:29] : unknown stats parameter 'stats' (expects 'hide-version', 'uri', 'realm', 'auth' or 'enable').
[ALERT] 032/163027 (24099) : Error reading configuration file :
/etc/haproxy/haproxy.cfg

One thing I did notice is that if I run the snmpbulkwalk with a less specific OID, I get an entry that might shed some light:

Does the /etc/snmp/snmpd.local.conf file need to exist? Is this where I should be placing the haproxy lines?

Any pointers on what I'm doing wrong?

Thanks
