> Hello, everyone!

> Ignite has a changeable jmx hierarchy now. It may lead a lot of problems for product
maintenance and monitoring:
>     - By default where would be classloader that change every time that node has been
restarted. It will lead to rediscover all metrics for node.
>     - It's hard to create a single template for different deployments. For example we
should have about 4 different templates for each combination of classLoader and instanceName.
>     - It's hard for engineers to switch between different hierarchies. You have to recreate
anything you already have.
> 
> I've created https://issues.apache.org/jira/browse/IGNITE-12920 to change this behavior.
I am going to:

>     1. Change IGNITE_MBEAN_APPEND_CLASS_LOADER_ID default value to false
>     2. Use instanceName in any case. If this option is set, the value will be used, otherwise
use consistentId if it's null use nodeId
>     3. Add option IGNITE_MBEAN_APPEND_INSTANCE_NAME for backward compatibility. True
by default
>     4. Update documentation according to changes
