Suppressing an write-only attribute in Splunk for JMX

[dcparker]

Hello,

I am using the Splunk for JMX app to monitor my Cassandra cluster and it's awesome. However, I do get an error in the splunk logs that I would like to get rid of.

Here's what happens: I am monitoring the entire mbean domain using:

<mbean domain="org.apache.cassandra.db" properties="*" dumpAllAttributes="true"/>

However, there is a single attribute in there that seems to be write-only:

01-21-2014 11:14:22.251 -0600 ERROR ExecProcessor - message from "python /opt/splunkforwarder/etc/apps/jmx_ta/bin/jmx.py" Error executing JMX stanza jmx://cassandra : Write-only attribute: CrcCheckChance

My question - is there a way to tell it to exclude that attribute or ignore the error? I could go through and list every property in that domain I suppose, but there are a ton and all of them are useful. The only problem is this error. Any help would be greatly appreciated!

PS - everything works fine even though this error is there, I would just like to get rid of it since it happens every call.

OK , I have released a new version (2.0.4) with this feature. Enjoy !

awesome, thank you!

dumpAllAttributes doesn't have any filtering capability currently.

I could add some code so that only "readable" attributes are polled when doing a bulk dump, there is a convenient method for this in the JMX API.

I'll put this on the TODO list and make a new release ASAP.

That would be awesome, thank you!
