probe for JOnAS logging analysis - Re: [architecture] Re: Re: Re: Re: Retrieve filename of the logging filesthroughJMX

[Dominique De Vito <dominique.devito@xxxxxxxxxxxxx>]

Georges,

You has written, you were trying to developp a probe which should 
analyse the logging of JOnAS and send alarms to a central repository.

So, I guess you might take a look at TPTP (http://www.eclipse.org/tptp).

The TPTP project (Test & Performance Tools Platform, ex-Hyades) aims to 
provide an extensible platform for test, monitoring, tracing and 
(possibly heterogenous and remote) application profiling.

TPTP v3.1 is released with 4 statistical agents :
* Windows Host (Perfmon): Standard Perfmon API metrics - CPU, network, 
disk etc..
* Linux Host: Standard /proc metrics - CPU, network, disk etc..
* JBoss J2EE Application Server: Counters exported by JBoss server (not 
by the Application running on the server).
* JOnAS J2EE Application Server: Similar to JBoss agent.

Note that the TPTP extensible platform contains agent (including one 
JOnAS agent), common data sets/models (in order to normalize data 
representation and then, to enable TPTP component interoperability)...

IBM has made a presentation about using TPTP for JOnAS monitoring during 
ObjectWebCon'05.

JOnAS by Christophe Telep, IBM
