0.71
- Added 'ns' as unit (CpuThreadTime returns nano seconds)
- Fixed quoting of performance data in so far to let
Nagios::Plugin the complete control
- Fixed '--color' option and UseColor config directive
(section: <Shell>) to j4psh
- Added detection of a suitable pager for j4psh
- Fixed bug in server configuration when using old style syntax
0.70 (2010-7-10)
- Extended configuration syntax for check_jmx4perl as an alternative to
command line options
+ Parameterized checks
+ Default values for parameters
+ Multichecks (one HTTP request, many JMX requests)
+ Check-Inheritance
+ Predefined checks for certain environments (as sample configuration files)
+ Added null value check, can be tuned with --null
- Added '--value' as a shortcut for --mbean/--attribute/--value
- Better documentation for check_jmx4perl (30 extra pages)
- <Server> sections are now named blocks, taking the server name as block
name (similar to <Check>). The old syntax with an "Name" argument is
still support but must not be mixed with the new syntax.
- Path elements containing '/' can now be escaped with '\/'
- j4p-osgi-bundle including pax-web-bundle so only a single bundle
is needed for deploying (when no OSGi HttpService is installed)
- Relaxed version requirements on core and compendium OSGi classes
for j4p-osgi bundle.
- Changed access restrictions (j4p-access.xml):
+ <allow> and <deny>
+ Wildcards (*) for attribute and operation names
+ WARNING: Semantics of MBean specification has changed. Please
read the comments in j4p-access.xml.template
+ Add logging (level info) for printing out which security policy
is used
- Started to add a java client library
- j4psh beta version added
- Agent:
+ Switched from JUnit to TestNG for testing because of
support of testing groups
+ New servlet init parameter option 'mbeanQualifier' to allow
multiple j4p-servlet in a single application server
0.65 (2010-3-30)
- A JDK 6 java agent added for exporting the j4p protocol via
HTTP/JSON.
- Extended READ operation to support MBean patternames and multiple
attributes with a single request
- Renamed 'max_depth', 'max_list_size','max_objects' as processing
configuration parameters to 'maxDepth', 'maxCollectionSize' and
'maxObjects' respectively for consistencies sake.
- Bug fix: POST request respect these parameters as well now
- Added 'ignoreErrors' request option in order to allow a bulk read
to succeed even if single read fails. In this case, the valu will
- 'search' returns properly escaped MBean Names if unsafe characters
are used.
- For GET request, instead of pathinfo a query with parameter 'p'
can be used as alternative. This works around certain issues with
special path handling with certain app-servers (e.g. Tomcat).
- JMX::Jmx4Perl::Request and JMX::Jmx4Perl::Agent hardened in order
to be more smart with unsafe MBean Names and detect automatically
the most convenient HTTP Request method (if not explicitely set)
- Added more unit and integration tests.
- Added VERSION command to JMX::Jmx4Perl to get to agent and
protocol version
- Fixed error handling for bulk requests. Now each request object
will return an associated response object even in the error case.
- Fixed JMX::Jmx4Perl::info for IBM JVMs
- Added JMX::Jmx4Perl->parse_name() for splitting up a given MBean
object name into its parts
0.60 (2009-02-28)
- OSGi bundle (including dependencies) for exposing JSON export via
the OSGi HTTP-Service. It's in agent/modules/j4p-osgi.
- Refined error handling
- Removed legacy JDK 1.4 support. 0.36 is the one and only version
for which the JDK 1.4 backport has been tested to some amount.
- Added support for overloaded JMX operations for 'list' and 'exec'
- 'read' operation can now be used without attribute name in which
case the value of all attributes is returned. This can be used
directly with JMX::Jmx4Perl and the frontend jmx4perl.
- Support for Resin 3.1 added
- 'exec' operation can now deal with simple array arguments. Within
the perl modules, give an array ref for an array argument. This
gets translated to a comma separated list of values in the
string. For string array this works only with simle content
(i.e. no element containing a ',')
0.51 (2009-12-30)
- Quickfix for a badly packaged agent/j4p.war
0.50 (2009-12-24)
- Protocol of j4p.war has been extended to enable proxy mode
- Added '--target' to check_jmx4perl for using proxy mode
- Added '--target' to jmx4perl
- Added Mule agent. Use maven to build it in agent/modules/j4p-mule
- 'get_war' and 'get_mule_agent' as actions for Build.PL for
fetching java artifacts from the labs.consol.de maven repository.
- Cleaned up and updated Manual.pod
0.40 (2009-11-14)
- Extended protocol to allow for JSON requests via POST in addition
to pure URL based requests via GET
- Implemented bulk requests: JMX::Jmx4Perl->request() can now take a
list of JMX::Jmx4Perl::Request objects in which case it will
return a list of JMX::Jmx4Perl::Response objects (instead of a
single, scalar, response when used with a single request)
- Support for Glassfish V3 Preview, Jonas 5.1 and Jetty 7.0.0
0.36 (2009-10-30)
- Added <remote> to j4p-access.xml for restricting
access to certain hosts or subnets only.
- Added support for a JDK 1.4 agent war. The feature base for
this agent is frozen. It might even vanish in the future.
You need a JDK 1.4 agent for running within Weblogic 8.1
- Cleaned up j4p agent with help of sonar and associated
metric checkers like PMD, check_style and FindBugs.
- Added support for config files in jmx4perl and JMX::Jmx4Perl
which allows for shortcuts for agent URL as well as storing
user and credentials information.
- Fixed some bugs
0.35 (2009-08-15)
- Added example 'threadDump.pl'
- Fixed bug when serializing floats and doubles.
- check_jmx4perl:
* Added support for checking string and boolean values

'max_objects' to restrict the size of the JSON answer. Protocol
has changed as well a bit.
- jmx4perl: URL now as first argument for easier workflow when using
bash history for repeated usage.
- Added support for restricting MBean access via a policy file
(j4p-access.xml)
0.21 (2009-07-03)
- Added '--proxy' for check_jmx4perl and jmx4perl
- check_jmx4perl:
+ Refactored to work within the embedded Nagios Perl interpreter
(ePN)
+ use relative values in the range from 0 to 100%
(for --critical and --warning) instead of [0..1]
+ Renamed '--base-value' to '--base' since it can take now
absolute values (numbers) or "mbean/alias/path" tuples as an
argument in addition to alias names.
+ Added '--operation' which allows for using return values of
operations as check values
+ Added ~ 50 integration tests
