A highly flexible Nagios/NRPE plugin for monitoring Java applications via JMX

jmxeval's Issues

Connect to a local vm via process id

I'm working with an application server in a production environment.
I don't like to open an other port and than ensure that nobody else can access to it.
It is strongly recommended to use SSL an client certificates, which means a lot of work and even more support.

It looks easier to me, to use the direct attach to the vm by the PID (there is a PID-file anyway) like jconsol seams to do.
I have to ensure the restricted access to the system user anyway.

Does not support E notation for very small or very large numbers

While using this tool to get some kafka metrics into nagios we stumbled upon this error:

Block [3.487953628987248E-5] in expression [3.487953628987248E-5 * 1] invalid

It seems that this tool does not support numbers that use the E notation, like 1.2E-3, into an <expr> element.

There is a problem using OpenJDK about tools.jar (http://openjdk.java.net/jeps/220).
Bypassed copying tools.jar from another JDK to plugin lib directory and modifying the classpath parameter.

Migration path from 1.2 to 2.0 xml

The update of jmxeval from 2.0 to version 3.x seems to require a migration as the 1.2 schema is gone. Sadly i cannot find a documentation for that. What do i have to change?

Error: Could not find or load main class com.adahas.tools.jmxeval.App

Hi,

I'm trying to get this to work under Redhat but I cannot get it to work. I keep getting the message; Error: Could not find or load main class com.adahas.tools.jmxeval.App

The check_jmxeval refers to jmxeval/lib directory which doesn't exist in your download. Am I missing something?

Thanks,

Disable time perfdata

Hello,

Would you consider adding an option to remove default time perfdata ? According to the code it looks like being hardcoded.

How to specify "not equal" in critical field?

For example, I need to alert in case the returned value is not zero

return value type when you execute an operation

If the return value type of an operation is a CompositeData you can not extract specific item values from it. It would be nice if exec tag has some extra attributes for this (similar with query tag).

How to reach tabular data type with JMXeval

Hello,

I would like to access Attributes values of memory used before and after garbage collector. However it is embedded inside tabular data type MemoryUsageBeforeGc within Composite type LastGcInfo.
Is it possible to get these data with JMXeval?

Thank you.

Doesn't support multiplying by 0 or 1

I got this error com.adahas.tools.jmxeval.exception.JMXEvalException: Block [0] in expression [0 * 1] invalid where 0 is the value returned by JMX and 1 is a constant in an expressions similar to ${Value} * 1.

Seems strange that such expression is invalid.
