Jonathan Ellis commented on CASSANDRA-4537: ------------------------------------------- Idea: show number of sstables / desired max, when we exceed the desired threshold? This would give you a quick eyeball of "here's where compaction is behind." SSTables in each level: [43/0, 8, 102/100, 123, 0, 0, 0, 0] > We should emit number of sstables in each level from JMX > -------------------------------------------------------- > > Key: CASSANDRA-4537 > URL: https://issues.apache.org/jira/browse/CASSANDRA-4537 > Project: Cassandra > Issue Type: Bug > Affects Versions: 1.0.0 > Reporter: sankalp kohli > Assignee: Yuki Morishita > Priority: Minor > Labels: compaction, leveled > Fix For: 1.2.1 > > Attachments: 4537.txt > > Original Estimate: 12h > Remaining Estimate: 12h > > We should add methods to this Mbean > org.apache.cassandra.db.ColumnFamilyStoreMBean > These metrics will be helpful to see how sstables are distributed in > different levels and how they move to higher level with time. > Currently we can see this by looking at the json file but with JMX, we can > monitor the historic values over time using any monitoring tool. -- This message is automatically generated by JIRA.
