Subject [jira] Commented: (HBASE-1414) add server status logging chore to ServerManager
Date Wed, 13 May 2009 00:12:45 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1414?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12708696#action_12708696

Andrew Purtell commented on HBASE-1414:

How about add metrics stuff in addition? I can see a Chore in ServerManager being a useful
place to drop in other stuff over time.

> Adds a small chore to master.ServerManager that logs the number of reporting region servers,
the number of region servers declared dead (and their identity), and the average load. Uses
the metaScanner period. Useful for those that tail the master log to get a sense of system
health, or are considering writing Nagios monitors etc. which do the same.
