Subject [jira] [Commented] (CASSANDRA-2405) should expose 'time since last successful repair' for easier aes monitoring
Date Tue, 21 Jun 2011 20:39:47 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2405?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13052815#comment-13052815
] 

Jonathan Ellis commented on CASSANDRA-2405:
-------------------------------------------

Nick and Tyler pointed out that we want similar information for basically everything that
runs on CompactionManager.  Maybe we could make the DetailedInfo cf take an arbitrary map
from CompactionInfo?  (Rename to BackgroundIODetails?)

> 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.
