Thanks Emilio.
Still, I'd like not to be tied to a CLI/bash interface...many external
controllers may not have directly CLI access (monitoring/alerting
frameworks, VM provisioning, IPS/IDS systems, etc).
I suppose one alternative is to write a quick Sinatra app which calls
the bash commands you reference below...this Sinatra app would live on
the ZenLB host...but again, I'd rather not have to write this interface
myself...pretty please?! :)

Hi Bryan, how is your shell/bash level?
Yoursel can do it in no more than 20 minutes
I attach you an example now you can modify or add new properties
Include the attached file zlbcmd in /usr/local/zenloadbalancer and
apply execution permissions
chmod +x /usr/local/zenloadbalancer/zlbmd
Take a look in the first lines you have to changes the variables
values with your
server,port,user and password for the webgui.
*root#zlbcmd --help *
zlb farmane action
action = [add|del]
if action eq add then
zlb farmname action rip_server
port_server timeout_server priority_server
if action eq delete then
zlb farmname action id_server
*all fields are mandatory so change timeout_server and priority_server
by x if can't introduce a value
i e:
*root#./zlbcmd tst add 192.168.2.2 80 x x
*with this I add a backend 192.168.2.2 with port 80 in my farm named tst
*root#./zlbcmd tst del 0*
with this I delete the backend with id 0 in my farm named tst
I checked with HTTPS farm profile and it works like a charm!
Enjoy it!

Bump.
From my perspective, lack of a RESTful API prevents ZenLB from
being a legitimate contender in the VM/automation world we live in.
I'd LOVE to write a chef cookbook which will add/remove a host
from a specific ZenLB pool when I deploy to my newly provisioned
VM... :)
Any chance this gets on the v4 roadmap?

Hi Humberto
There isn't yet API implemented in Zen, we developed functions
that the zen lb web gui uses. If you want to develope some
functionality can use the functions that web gui uses in
/usr/local/zenloadbalancer/www/*functions.cgi
There isn't documentation about this functions. I recognize if
you don't have too much knowledge about perl it could be a hardw
work

Hi!
I would like to have an API, preferably REST API, to manage
the Zen LB from program code. For what I have seen, such API
does not exist at the moment, right? But Zen has a Web
interface, so I was wondering how is this interface
implemented. Is the web server embedded into the LB itself,
or is the web server communicating via a given API with the
LB? Thanks!
Cheers,
Humberto
