Hi willy, Can you elaborate more on this point you can enable SNMP using the tools in the contrib/ directory and monitor it just like the rest of your network components ;
are there generic steps defined to setup this up? when i tried the steps from readme i get this error $ perl haproxy.pl Can't locate NetSNMP/agent.pm in @INC (@INC contains: /etc/perl /usr/local/lib/perl/5.10.1 /usr/local/share/perl/5.10.1 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.10 /usr/share/perl/5.10 /usr/local/lib/site_perl .) at haproxy.pl line 18.

I know some people who receive SMS when one of their servers go down, and I know that others receive mails, in fact anything can be done when combined with the appropriate tools. Regards, Willy
