- I think you might to say "Derby JMX Components" because the last section was a general overview of JMX, and one might think this was still about JMX in general
okay.
- In the figure you have a JDBC Service MBean, but in the table it's not there and you have a Driver MBean. Are these the same?
Yes. They are the same. I'll correct the table.
- I think it might be worth going int more detail on how a Model MBean works since this is what you're proposing to use. I liked this text from http://www.admc.com/blaine/howtos/jmx/ch06.html
Umm...I have mixed feelings on that. I initially thought a sperate article along with this document will be good. At the same time, it is always good to have some refersher information in HLD. I did not want the HLD to look like a model mbean tutorial. How about a seperate article describing all Model MBean soup and putting a link in HLD?I think it will be much better to have a few supporting articles and keep HLD clean. Let me know what you feel. I'll be happy both ways.
- I think you need to clearly define some terms to help avoid confusion: In particular, I think it's important to make sure we're all on the same page as to what a "Monitor" and "Service" are (I'm assuming these refer to the Derby concepts of monitor and service).
Umm..I guess a "Definitions" section can be added. This will clearly identify what "Monitor", "System", "Service" etc. mean in the rest of the document?
- I'm not sure if MonitorMBean is the right name, as this is an internal concept. What is the right name for this MBean from the perspective of the user? I think a Monitor has a 1-1 correspondence with the Derby concept of a "system" -- see http://db.apache.org/derby/docs/dev/devguide/cdevdvlp27610.html
Exactly. I thought from developers perspective. Looking from a users perspective, it would make much more sense to call it as SystemMBean. When viewed from a cosole, it would be much more intutive to the user if this mbean is displayed "System" or "Derby System"
- I'd like to see a summary of the methods, properties and callbacks for each MBean. I'd also like to see something like a UML diagram showing the relations between MBeans. For example, I think there is a 1-many relationship between Monitor MBean and Database MBean.
Okie dokie! I'll put the uml on wiki and the summary in a table up on the wiki. Thank you for your comments!!! Best Regards, Sanket
