Programmatically enable/disable JMX input

batsonpm — Thu, 09 Aug 2018 14:13:42 GMT

We have one JMX input that needs to be disabled and then re-enabled every now and then. I am trying to figure out how to do this in an automated fashion thru Automic. So I am trying to understand how the command works by running it directly on the linux server the forwarder is running on.

I found the jmx through the webpage

But I am unfamiliar with how to work with the REST API. I have tried the following from other answers I have found here:

curl POST -k -u admin:password https://servername:8089/servicesNS/nobody/SPLUNK4JMX/data/inputs/jmx/helloworld -d disabled=true

I have tried to run the command on the linux server that the forwarder is on, and I get the following error:

user:~$ curl POST -k -u admin:password https://servername:8089/servicesNS/nobody/SPLUNK4JMX/data/inputs/jmx/helloworld -d disabled=false
    curl: (6) Could not resolve host: POST; Unknown error
    <?xml version="1.0" encoding="UTF-8"?>
    <response>
      <messages>
        <msg type="ERROR">Argument "disabled" is not supported by this handler.</msg>
      </messages>
    </response>

I see the key from the GET command I need to change:

<s:key name="disabled">1</s:key>

But I seem to be missing something on how to actually change the value because of the error shown above.

GET command results:

curl: (6) Could not resolve host: GET; Unknown error
<?xml version="1.0" encoding="UTF-8"?>

Any help would be appreciated!

Thanks!

Figured it out:

curl -k -u admin:password https://servername:8089/servicesNS/nobody/SPLUNK4JMX/data/inputs/jmx/helloworld/disable -X POST

curl -k -u admin:password https://servername:8089/servicesNS/nobody/SPLUNK4JMX/data/inputs/jmx/helloworld/enable -X POST
