[asterisk-users] asterisk manager interface stability

[Matt Florell]

The issue has more to do with the sheer amount of data passed to the client
from within the Asterisk application when you have 50-100+ clients connected
to the AMI on full output mode. Running a system with FreePBX/Trixbox
especially generates vast amounts of output that has to be generated on
every AMI connection for every client. This is not trivial and can result in
lockups very easily, although this has gotten much better since the early
1.0 versions.

The new Asterisk Manager web API in 1.4 is a good step where sending of
Actions does not require an actual Telnet conneciton to the AMI, but I think
to be able to handle larger numbers of concurrent connections that a
separate send-only and a separate receive-only type of interface be built
where Asterisk would just output all AMI data to a single server-like
application that would then broadcast it to all connected clients. This
would remove the burden of so many connections going directly into Asterisk
and would allow for much larger scaling of AMI-type applications that
require real-time output of AMI events.

As for how to go about doing this, I can't help you there. I did build a
very specialized version of something like this 4 years ago for the
astGUIclient project called the Asterisk Central Queue System(ACQS) It is
based on 1.0 Asterisk but it still works with 1.2 and 1.4. It is limited in
what it does, but it does scale much better than using direct AMI
connections.
