Actually.. "dedicated" monitoring's can be very cheap - and for those with a
Virtual environment --> you can run them with as little as 512 mb for each.
That aside for me it's mostly what is required to send out mails (postfix etc)
that ups the resources (every bit counts ;))
i do agree for some specially small environments it will be beneficial but it
should be some form of an option (if not for the resources then for double
mails on errors ;))
For the colors part i really haven't got much of an idea yet.. we have only
experimented with zen for a little bit.. and are currently waiting for NAT
support.
(as anti-spam/ fail2ban/ etc can't work with sNAT so that means our servers
have to run less secure in case we want to use loadbalancer with sNAT at this
point - can't afford that with daily brute force attempts and 1000's of spams
^^)
Little side note: hopefully NAT will be supported before Juli (thats when our
new environment will launch.. hoping to do that with a zen loadbalancer to go
with it haha :)
Regards,
Marco

Subject: Re: [Zenloadbalancer-support] Enhancement request - Farm
Monitoring/SMTP
Date: Mon, 20 Feb 2012 17:21:55 +0000
Hi All I understand the concerns about overloading ZLB by adding monitoring
tools, and the benefits of using external 'dedicated' monitoring equipment -
but we are not large enough to have that level of monitoring, but benefit
massively from the load balancing ZLB offers. So a simple SMTP report on
exception changes to Farm status, 'real' server availability, FarmGuardian
triggers - would be helpful. Even if this SMTP feed can't cant be done, how
about a series of colours? We already have RED for OFF, GREEN for ON, YELLOW
for MAINTENANCE... how about BLUE for 'FarmGuardian fault'? I think a quick
the summary screen could also display a quick count - maybe a percentage of
'availability' ? eg Example Farm A - 5 real servers, 1 in maintenance mode, 1
with FarmGuardian fault -> would show 60% available What do you think? 3
greens 1 yellow 1 blue Nick
