I have read in a document called "How to write a TPTP Data Collection

am quite new to this and I would like somebody to confirm if I understand
thaings well:
1- The RAServer available as binaries for various platforms is one example
of such a data collection agent, and also available as source code in the
CVS repository in org.eclipse.hyades.datacollection/collection/framework
2- It is possible to write a data collection agent in Java rather tha in
C. So, is it possible to write in Java an exact equivalent of the C based
RAServer? Is there already such a thing? Does the
org.eclipse.hyades.logging/core/LoggingAgent.java example have anythiong
to do with it?
Thanks in advance for your answers,
Fred

Hi Fred,
The RAServer is the TPTP Agent Controller and is responsible for the
instantiation and management of agents. It facilitates communication between
the agent and the workbench. When a request to create a particular agent is
received from the workbench, the agent controller will create the agent. The
agent process then establishes communication with the agent controller,
which then passes information on into the workbench. Any subsequest commands
that the workbench sends are forwarded through the agent controller to the
agent process.
The agent controller is native only, but has been ported to a variety of
architectures (these are the binaries you noted).
So, in response to (1) - no, the agent controller is not an agent. The
source for the agent controller is currently in
org.eclipse.hyades.datacollection/collection/framework. This plugin
contains the source for a variety of native agents as well. For example, the
source for the Perfmon Agent is in
org.eclipse.hyades.datacollection/collection/collectors/perf mon...
The PerfmonAgent is an example of a C agent.
(2) Yes, an agent can be written in C or in Java. The agent controller is C
only, but libraries are provided to facilitate communications with Java
agents.The LoggingAgent.java class is an example of a Java agent. Another
example would be the JmxAgent in
org.eclipse.hyades.datacollection/collection/collectors/jmxa gent
Hope this helps..
