Subject [jira] [Updated] (CASSANDRA-6054) cluster availability report
Date Wed, 18 Sep 2013 11:24:52 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-6054?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Wojciech Meler updated CASSANDRA-6054:
--------------------------------------

    Description: 
It would be nice to have a way to check cassandra cluster status in terms of availablilty
for operations on keyspace at given consistency level.

Such operation should output information in availbility matrix where dimensions are:
- consistency level
- datacenter

and values are percent of ring available in DC at given consistency level, f.e.:

consistency level                  | DC1  | DC2 
CL.One                             | 100% | 100% 
CL.LocalQuorum                     | 95%  | 100%
CL.All                             | 90%  | 90%

Unfortunatelly c* don't have CL.LocalAll, so DC split in last line have limited sense ;).

It is valuable information for operations teams.
