[jira] [Commented] (ZOOKEEPER-1183) Enhance LogFormatter to output
additional detail from transaction log
[ https://issues.apache.org/jira/browse/ZOOKEEPER-1183?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13107589#comment-13107589 ]
kishore gopalakrishna commented on ZOOKEEPER-1183:
--------------------------------------------------
New output format
time:8/15/11 2:52:10 PM PDT session:0x131cf1a236f001e cxid:0x0 zxid:0x1189 type:closeSession path:/test version:10 data:48656C6C6F20576F726C6421
Used HexBinaryAdapter to marshal data byte[]
To get the byte[] from data one can do new HexBinaryAdapter().unmarshal("48656C6C6F20576F726C6421").
Can some one tell me when will a MultiTxn happen. Currently that is not formatted using the above logic.

> Though this is good information, it does not provide additional information like
> createSession: which ip created the session and its time out
> set|get|delete: the path and data
> create: path created and createmode along with data
> We can add additional parameter -detail and provide detailed output of the transaction.
> Outputting data is slightly tricky since we cant print data without understanding the format. We need not print this for now.
