jmxeval's Issues

possible enhancements

1) allow variable definitions from the command line
    -- this will allow passing the connection information on 
         the command line instead of having it hard coded 
         into the check scripts (we have 100's of servers to monitor)

2) Use the standard nagios plugin range specification (ugly but standard)
   -- http://nagiosplug.sourceforge.net/developer-guidelines.html#THRESHOLDFORMAT

Would you be willing to accept patches for the above?

Don't display performance data for "time" in case of Status UNKNOWN

What steps will reproduce the problem?
1. Force the check to return UNKNOWN, e.g. by configuring a wrong connection 
port

What is the expected output? What do you see instead?
I see the error message together with performance data for "time" which will 
produce an conflict with rrd_update

What version of the product are you using? On what operating system?
1.2.6 / Ubuntu 10.04 LTS

Please provide any additional information below.

To solve the problem I changed the source code in App.java:

...
     // process the evals
      jmxEval.process(context);

      // set elapsed time in seconds
      final double elapsedTime = (System.currentTimeMillis() - startTime) / 1000;

      // return status value to indicate execution status
      returnValue = context.getResponse().getStatus().getValue();

      // Dont produce performance data for "time" in case of return value UNKNOWN
      if (returnValue != 3) {
          context.getResponse().addPerfData(new PerfDataResult(
             "time", String.valueOf(elapsedTime), "s", null, null, null, null));
      }
      // print response
      outputWriter.println(context.getResponse());

    } catch (ConfigurationException e) {
...

Need more documentation please

Are there updated entries for the wiki available? All the options at the bottom 
of the getting started guide are things I'm looking to do:

Multiple simple attribute checks (Thread count check)
Using composite attributes and mathematical expressions (Heap memory usage 
check)
Regular expression based check (Tomcat version check)

Any more information about configuring the xml to do these checks would be 
really useful. I'm trying to get data out of a custom tomcat application that 
can't be used with any of the standard tomcat nagios checks. JMX seems to be 
the best way to get data out but I need to do max / current heap usage, max 
/current web container threads, max / current jdbc connections, tomcat version, 
running states, etc from a single command. I also need performance data to be 
generated.

Hopefully some updated documentation will allow me to do that.

Thanks!

Arithmetic format for tiny values

(Not sure if this awesome project is still alive, let's give it a try.)

What steps will reproduce the problem?
1. Check process CPU load (java.lang:type=OperatingSystem->ProcessCpuLoad)
2. Apply some arithmetic operation on the result (eg: *100 for proper 
percentage)
3. This results in an IllegalArgumentException error if the value is under 0,001

What is the expected output? What do you see instead?
* Expected: 0,0009501108462653976
* Saw:9.501108462653976E-4

What version of the product are you using? On what operating system?
* v1.2.6

The format returned by JMX is not properly interpreted by the library, some 
rounding should be applied for tiny values, or "0" should be returned.

All substitutions in <perf> section.

What steps will reproduce the problem?
1. Add <query> section to get the max non-heap memory size.
2. Add "max="${nonHeapMemoryUsageMax"" to the <perf> section

What is the expected output? What do you see instead?
Output should include the maximum non-heap memory size in the performance 
section.  Instead the variable is printed.

What version of the product are you using? On what operating system?
1.2.6

Please provide any additional information below.
