JMX Monitoring app issue with Operation with null parameter

ramanjain1983 — Mon, 28 Sep 2020 20:04:54 GMT

Hi there,

I am trying to call an operation getActivities of Tibco BW which has a parameter name ProcessDefinition which is of string type. When I am executing this operation from Jconsole it is executing with default values which is actually blank or null. However when I have it defined in the config like this :

then it is not able to collect anything. I am getting the below message in index=jmx:-

********* mbean_domain="com.tibco.bw",mbean_property_key="engine",mbean_property_name="SMEC_EAI_ISM_IM-SMEC_EAI_ISM_IM",GetActivities=""

Looks like for some reason the blank is not going into the parameter value. However when I tried similar kind of mbean where the parameter value was Active , it worked like a charm.

Is that expected behaviour or am I missing something.

Thanks.

Do either of these configs work :

Passing no parameter :

<operation name="GetActivities" outputname="GetActivities" />

Entering a single blank space as the parameter value :

<operation name="GetActivities" outputname="GetActivities">
  <parameter value=" " type="string"/>
</operation>

Thanks for answering.

I have tried this before with no luck.
If I try the first option which you said then I even do not get GetActivities field in the logs. Also it prints and error log with null.

ERROR ExecProcessor - message from "python /data/apps/splunk/etc/apps/SPLUNK4JMX/bin/jmx.py" Error executing JMX stanza jmx://helloworld : null

Second option, prints the same result as I mentioned in my original post. By the way this bean is TabularType and have Composite data in it.

Can you post a screendump from JConsole showing the MBean defintion tab for the Operation (so I can see what the method signature looks like).

Is it this from page 180 : https://docs.tibco.com/pub/activematrix_businessworks/5.9.3_march_2012/pdf/tib_bw_administration.pdf

So it has to take a single String argument.

Therefore you have to use the format :

Regarding what the "something" value can be , I don't know what the documented valid values are for this field , so you'll have to refer to the Tibco docs.

yes that is correct. Though i am using 5.12 version which is quite same for that operation.

the problem is that while executing this operation from JConsole or any other client, I just need to leave it blank or null to retrieve everything. Hence this is weird but that something is either "" or "null" but none of them is working.

I will check with Tibco guys as well if this is expected behaviour or a bug in the Mbean operation. However I am assuming that your code is designed to pass the blank parameter value and not to ignore the parameter completely if the value is blank or null. Is that the case.
