[jira] [Created] (CASSANDRA-3495) capture BloomFilter memory size
in Cassandra (JMX)
capture BloomFilter memory size in Cassandra (JMX)
--------------------------------------------------
Key: CASSANDRA-3495
URL: https://issues.apache.org/jira/browse/CASSANDRA-3495
Project: Cassandra
Issue Type: New Feature
Reporter: Jackson Chung
Priority: Minor
Maybe this could be done in https://issues.apache.org/jira/browse/CASSANDRA-3347 also, but not sure what's the scope in that jira. It'd be great if the BF memory size can be captured in the JMX monitoring.
Though not sure how you would capture the "heap size" (easily that is) of the object. There is a BF.serializedSize() , can this be exposed to the BloomFilterTracker and DataTracker... and use this instead? Anyway, will let the implementor to decide/design

Attachment: 0001-Add-BloomFilter-Serialization-size.patch
Simple patch to add bf disk usage in the cfstats. I was thinking of using memory meter to measure the inmemory size but the over head in memory is almost constant and hence thought choose a simpler solution.
Let me know if you guys think otherwise.
