Subject [jira] [Commented] (S4-65) Create s4 status command
Date Fri, 13 Jul 2012 00:58:33 GMT


Aimee Cheng commented on S4-65:

|Total nodes is the current number of active nodes right?
Yes, now is the number of active nodes. I used to think total nodes including active nodes
and standby nodes. But now the total number is active nodes. I'll change the description for
the current version.
I'll follow the last two comments to update my code. very nice suggestions!

> We should have an "s4 status" command that provides nicely formatted information about
the state of S4 application coordinated through a given Zookeeper ensemble.
> In particular:
> - which applications are deployed
> - on which S4 nodes these applications are deployed
> - how many S4 nodes are running, how many S4 nodes are in standby
> - which streams are published, which applications are connected
> The implementation would probably add a new class in the s4-tools project.
