Hey Guys,
I am brand new to this list. This is my first message.
I was thinking about suggesting an enhancement to the remote engine piece of
JMeter server.
(See code example question below)
I am currently working in a grid environment. My company uses a cluster of
grid "nodes" in order to facilitate processing batch and real-time
transactions. I have been tasked with benchmarking web services transactions
running through our grid. I recently built a software router to handle
subscriptions to a load-balancer (BigIP - F5). So, my first task with JMeter
will be to benchmark the registration/withdrawal of subscriptions through
this setup.
One of the problems that presents itself to me is that - all grid nodes are
"hands-off" to users of the grid. In other words, the only control over a
grid node is through a web page (or 'generic' user). There is no way to
manually log on to the grid node. Also, since the grid nodes rely on NFS
shares to read-write to/from files (unsuggested), there is no good way to
maintain a list of all grid nodes belonging to one "cluster", as nodes
come-up and go-down.
My plan is to set up many nodes that will serve as remote JMeter engines. In
my situation, it would be beneficial to me to allow the controlling client
(gui) to automatically "discover" all nodes and their ip addresses as
participants in the remote pool of servers. This way - I don't have to jump
through hoops to setup all the ip addresses from all the remote servers in
the controllers property file.
I am currently trying to discover how the remote server portion of the code
works exactly.
I have noticed in the class:"RemoteJMeterEngineImpl.java"
that there is a method, " public void setHost(String host)".
Does this method get called during the client setup or during the remote
servers' setup?
How about having the Remote server discover its own IP address....i.e.
InetAddress local = InetAddress.getLocalHost();
_hostname = local.getHostAddress();
...instead of just the name of the host. (NOTE: the above code retrieves the
actual ip address)
Then, after the remote server discovers its ipaddress, it could "push" it to
the controlling client - whose address is specified in a deployed property
file.
So the idea is - deploy a JMeter remote engine along with a property/config
file containing the controlling clients ip address....and then have all the
remote servers "push" their ip address back to the (already running) client.
Any thoughts about this suggestion?
Thank you for your patience
