Subject [jira] [Commented] (S4-65) Create s4 status command
Date Mon, 09 Jul 2012 03:25:33 GMT

    [ https://issues.apache.org/jira/browse/S4-65?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13409146#comment-13409146

Aimee Cheng commented on S4-65:
-------------------------------

For monitoring, the metrics considered to be provided as follow: 

    basic metrics (APP/PE/PE instance): 
         - event rate
         - event processing time
         - event queue size
         - number of PE instances
         - number of processed events ( maybe within a sliding window)
         - exceptions during event processing 
         - actor nodes
 
    other:
        - APP: PE types
        - PE: keys
        - PE instance: key, TTL, survival time and other informations.

We'd like to use Codehale's Metrics(http://metrics.codahale.com/) to measure these metrics
in S4. By Metrics, the results are visible via JMX, HTTP, and also can be easily exported
to many other monitoring tools.

> 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.
