What is the character limit supported for defining an RPM probe name.

When a configuration attempt is made with a name longer than 32 characters, you will see this warning in the provided example (uses 35 characters):

<load-configuration-results>
<rpc-error>
<error-type>protocol</error-type>
<error-tag>operation-failed</error-tag>
<error-severity>error</error-severity>
<error-message>/tmp/cfg_push_18084115.conf:6239:(58) Length 35 is not within range (1..32)</error-message>
<error-info>
<bad-element>xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx</bad-element>
</error-info>
</rpc-error>
<rpc-error>
<error-type>protocol</error-type>
<error-tag>operation-failed</error-tag>
<error-severity>error</error-severity>
<error-message>/tmp/cfg_push_18084115.conf:6249:(9) error recovery ignores input until this point</error-message>
<error-info>
<bad-element>}</bad-element>
</error-info>
</rpc-error>
</load-configuration-results>
its because
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
is too big string, Length 35 is not within range (1..32)

The character limit is 32 characters and is expected behavior. There are no plans to increase the limit at the time of this writing.
