The Pushy Client Simulator allows you to start up many pushy clients inside a single Erlang VM.
The Clients are named according to the hostname and a unique client
identifier. This allows to shut down the clients and start them up again
where they keep the same name but have a different Instantiation ID.
The name is constructed as hostname()-XXXX where XXXX is a 0-padded
numeric Id representing the client. An example is private-chef-0001
for a client created on the default Erchef VM with pushysim loaded.
All clients currently follow the standard success state transitions
(i.e. COMMIT -> ACK_COMMIT, RUN -> ACK_RUN, COMPLETE, i
ABORT -> ABORTED).
The public API is exposed through the pushysim module.
pushysim:start_clients(N)- Start up N clients (numbered 1..N) that connect to the pushy server and start heartbeating
Currently there is no code in pushysim to allow you to start jobs via
the REST API. In opscode-pushy-server branch jc/OC-3256/pushysim
there is a helper function pushy_tools:send_job(Hostname, N) which can
start up the job submission cycle to pushysim clients on a given host.
On dev-vm the hostname is <<"private-chef">> by default so execute
inside the pushy-server VM:
> pushy_tools:send_job(<<"private-chef">>, 100).
to send a job to the clients named "private-chef-0001" to
"private-chef-0100".
- Handle server heartbeats
- Allow for different state transitions to exercise error cases
- Implement erratic heartbeating
