[jira] [Issue Comment Edited] (CASSANDRA-2405) should expose 'time
since last successful repair' for easier aes monitoring
[ https://issues.apache.org/jira/browse/CASSANDRA-2405?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13048506#comment-13048506 ]

---------------------------------------------------------------------
I think I will go with this model: key - "{KS}/{CF}" (string), columns are times repair completed successfully, subcolumns are range (string) and started_at (millis). That will it easy to query time since last successful repair + will give us a change to store valuable information.

> The practical implementation issues of actually ensuring repair runs is somewhat of an undocumented/untreated issue.
> One hopefully low hanging fruit would be to at least expose the time since last successful repair for a particular column family, to make it easier to write a correct script to monitor for lack of repair in a non-buggy fashion.
