Thu Sep 14 09:48:08 2017  paulomotta:spodkowinski: were the logs on MerkleTree at debug level on #13052 intended or an overlook from debugging phase? they're quite verbose: https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/utils/MerkleTree.java
Thu Sep 14 09:48:09 2017  CassBotJr:https://issues.apache.org/jira/browse/CASSANDRA-13052 (Resolved; Fixed; 3.0.14, 3.11.0, 4.0): "Repair process is violating the start/end token limits for small ranges"
Thu Sep 14 09:48:44 2017  paulomotta:could we maybe lower it to TRACE? WDYT ? (they can be quite useful while debugging, but quite verbose for debug.log)
Thu Sep 14 09:58:15 2017  spodkowinski:Those messages are intended for debugging the merkle tree code, yes. That's why they are logged to debug.log using the DEBUG log level :)
Thu Sep 14 10:04:47 2017  paulomotta:for the same reasoning, we should print gossip messages to debug.log as well.. :)
Thu Sep 14 10:05:05 2017  paulomotta:but I can understand if it was intended, I was just wondering, since they're quite verbose.

Thu Sep 14 10:28:14 2017  spodkowinski:it's not too verbose if I want to test repairs on my local machine.. could be on busy production systems, but I'd not recommend to enable debug on root level on these systems anyways. so in what context are we talking about debug.log here?
Thu Sep 14 11:31:19 2017  krut:spodkowinski: you'd be surprised how many actually do enable debug though
Thu Sep 14 11:35:40 2017  paulomotta:spodkowinski: it's enabled by default since #10241
Thu Sep 14 11:35:40 2017  CassBotJr:https://issues.apache.org/jira/browse/CASSANDRA-10241 (Resolved; Fixed; 2.2.2, 3.0.0 rc2): "Keep a separate production debug log for troubleshooting"
Thu Sep 14 11:53:03 2017  spodkowinski:paulomotta: To answer you question, I'd not lower the log level of mentioned messages to trace, as I'd find them quite useful for debug and troubleshooting purposes. But maybe we just have a different understand of the purpose and target audience of the debug log.
Thu Sep 14 11:54:09 2017  spodkowinski:did you actually send the proposed logging guidelines from the ticket above to -dev? was that something that has been agreed upon? if yes, should we add this to the documentation?
Thu Sep 14 12:13:17 2017  krut:oh yeah that would definitely be nice in the contributing section of the wiki
Thu Sep 14 12:23:14 2017  rustyrazorblade:wiki is dead :)
Thu Sep 14 12:26:22 2017  krut:i meant the docs
Thu Sep 14 12:26:23 2017  krut:you get it
Thu Sep 14 12:26:28 2017  krut:it's still a wiki
Thu Sep 14 12:53:21 2017  iksaif:hello, can I haz review for https://issues.apache.org/jira/browse/CASSANDRA-13677 ?
Thu Sep 14 13:57:22 2017  jasobrown:iksaif: looks, small, so i'll try to do it today
Thu Sep 14 13:57:37 2017  jasobrown:also, was gonna get to #13651 if i can
Thu Sep 14 13:57:37 2017  CassBotJr:https://issues.apache.org/jira/browse/CASSANDRA-13651 (Open; Unresolved; 4.x): "Large amount of CPU used by epoll_wait(.., .., .., 0)"
