snmp monitoring for apache-2.0.54 (comes in zimbra 4.0.2)

[scalper]

I am testing one monitoring OSS. I would like to monitor the apache of zimbra. I installed snmp1.0.0.

   % tar -zxf agent-2.7.3/product_connectors/snmp-x.x.x.tar.gz
    % cd snmp-x.x.x
    % ./build_apache_snmp.sh 2.0 /opt/zimbra/httpd-2.0.54/bin/apxs
    % cp snmp_module_2.0/module/*.so /opt/zimbra/httpd-2.0.54/modules
    % cp snmp_module_2.0/conf/snmpd.conf /opt/zimbra/httpd-2.0.54/conf
    % mkdir /opt/zimbra/httpd-2.0.54/var

add the following at httpd.conf

LoadModule snmpcommon_module modules/libsnmpcommon.so
LoadModule snmpagt_module modules/libsnmpmonagt.so
SNMPConf   conf
SNMPVar    var
ServerName hostname.domain:80

Restart the apache using zmapachectl.

But still, I am unable to get my snmp up. does anybody here have experience in getting it up and running? In the directions.. It is noted

NOTE: Apache build must be configured with shared module support (--enable-so).

Sorry for this unrelated question, but I think there should be more admins out there that would like to monitor their server from a centralized workstation rite?

Thanx.
