Hi Bhavesh,
Yes, if you look at https://issues.apache.org/jira/browse/KAFKA-1481 it
describes this sort of a problem with various delimiters used by Kafka. As
Jun suggested, I'll start a new thread and try to clearly explain the
problem.

Hi Jun,
I also wanted to highlight the implication of having a dot "." as part of
the topic and client.id with ".". Both topic name and client id need rule
enforcement.
JMX Bean names are not correct:
eg:
I have topics called "topic.dot" and client.id as "my.client".
JMX Bean name is:
ka
Yes, that description is not precise. We do allow dots in general. However,
a topic can't be just "." or "..".
Thanks,

Ah -- I only tested with dots "."
However, haven't you said earlier in this thread that only "-" and "_" are
allowed as special chars? This would exclude dots, although in the error
message below they (dots) are said to be fine. Is this a bug or a feature? ;-)

Actually, we do give you an error if an invalid topic is created through
CLI. When we add a create topic api, we can return the correct error code
too.
bin/kafka-topics.sh --zookeeper localhost:2181 --create --topic="te+dd"
--partitions 1 --replication-factor 1
Error while executing topic command
Wouldn't it be helpful to throw an error or a warning if the user
tries to create a topic with an invalid name? Currently neither the
API nor the CLI tools inform you that you are naming a topic in a way
you shouldn't.
And as Otis pointed out elsewhere in this thread this ties back into
the JMX/M
We actually don't allow "." in the topic name. Topic name can be
alpha-numeric plus "-" and "_".
Thanks,
Jun

Thanks, I was using without JMX. I will go through doc. But how about
Topic or Metric name Topic Name Convention or Metric Name Convention ? The
dot notation with topic having a ".". Any future plan to enforce some
stand rules.
Thanks,

If your topics or hosts have dashes or underscores or your topic has dots
you will have trouble extracting things from JMX. We provided a patch to
change delimiter character in MBeans and are hoping it gets inc
Hi Bhavesh,
Each of those JMX attributes comes with documentation. If you open up
jconsole and attach to a jvm running the consumer you should be able
to read the descriptions for each attribute.

Kafka Team,
Can you please let me know what each of following Metrics means ? Some of
them are obvious, but some are hard to understand. My Topic name is
*TOPIC_NAME*.
can we enforce a Topic Name Convention or Metric Name Convention. Because
in previous version of Kafka, we have similar issue
