[jira] [Commented] (CASSANDRA-7276) Include keyspace and table
names in logs where possible
[ https://issues.apache.org/jira/browse/CASSANDRA-7276?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14723905#comment-14723905 ]
Robert Coli commented on CASSANDRA-7276:
----------------------------------------
As an operator the log messages in which I most need Keyspace are the ones that relate to flushing, like these :
{quote}
INFO [ScheduledTasks:1] 2015-08-31 10:29:08,618 ColumnFamilyStore.java:912 - Enqueuing flush of sstable_activity: 4672 (0%) on-heap, 0 (0%) off-heap
INFO [MemtableFlushWriter:458] 2015-08-31 07:29:08,617 Memtable.java:347 - Writing Memtable-sstable_activity@1628471115(0.521KiB serialized bytes, 216 ops, 0%/0% of on/off-heap limit)
{quote}
If I had keyspace info, I would would grep -v all system keyspace activity. But now I have to enumerate a list of all system keyspaces and grep -v that.
The compaction ones at least contain a string that I can trivially remove via grep, "/system/" :
{quote}
INFO [CompactionExecutor:7] 2015-08-31 07:29:08,627 CompactionTask.java:141 - Compacting [SSTableReader(path='/mnt/cassandra/data/system/

> We should try to include info on the keyspace and column family in the error messages or logs whenever possible. This includes reads, writes, compactions, flushes, repairs, and probably more.
