Hello,
Thank you for your helpful replies.
One final query- can i access zeromq to send messages from
shell scripts (Linux) and Command Line scripts(Windows)? That
is what I would prefer to do- however I dont know if its
possible.
Yours sincerely,
Arvind,
Creatrix IT Soft.

ZMQ's memory utilization while messaging will - among other
things - depend on the zmq socket options and how you
implement messaging. It sounds like you are going to be
exchanging small messages and not transferring very large
chunks, you should be able to reduce memory usage of zmq. My
first guess is tuning SND/RCVBUF SND/RCVHWM zmq socket
options and using zmq_recv/zmq_send calls if you are very
concerned and want the lowest memory usage.

Hi
I am building a platform for deploying apps to cloud- I wish
to use a mechanism for monitoring metrics of servers running
apps for which I am considering zeromq- but one concern is
the amount of RAM/CPU utilised by the process that sends data
to monitoring server via ZeroMQ- since the machine (where
this process is running) itself may have as low as 512MB
RAM(or less) and the client’s app will be running on this
machine as well. Hence I want the process that sends messages
via ZeroMQ to use as less RAM/CPU as possible.
Yours sincerely,
Arvind,

Arvind,
RAM/CPU usage will be consistently low using ZeroMQ using
either java or python (both can run on linux & windows).
The memory footprint of the process really depends on the
implementation. I know that, using python, I can serialize
and compress a dictionary (aka "unordered map") using pickle
(object serializer) and zlib (for keeping payload size small)
and send it over the wire via ZeroMQ without any sort of
memory or CPU concerns.
However, I don't think that this is the right way to do this
kind of performance monitoring. Both Windoze and Linux
variants have tools or mechanisms built-in to the OS to do
performance monitoring on a process. For windows, you would
want to use WMI
<http://technet.microsoft.com/en-us/library/cc767879.aspx>.
For Linux, you'd want to use command line tools that are
available
<http://www.cyberciti.biz/tips/top-linux-monitoring-tools.html>.
What's the real problem you're trying to solve here?

Hi
I wish to create a simple process that basically measures the
CPU/RAM utilisated by a running process on that server, and
sends it via ZeroMQ.
With the multiple language bindings available for ZeroMQ, I
wish to use that language(for utilising ZeroMQ)- that uses
the least possible RAM. And ideally I can compile/create the
ready to run process on my machine, and then run it on any
OS(including Linux—> Ubuntu/CentOS and Windows) and for
different types of RAM/CPU configurations. I understand that
ZeroMQ core will have to be installed/made available for use
by my process.
Any insights intot
Yours sincerely,
Arvind,
