> {color:blue}Currently ZooKeeper provides utility java program to view the snapshot and transaction off-line but these are not easy to use, also the content is less understandable {color}
> In this improvement task I propose following functionality:
> 1) add zkTool.sh script to view snapshot and transaction.
> Usage: zkTool.sh -COMMAND <transaction/snapshot file>
> where COMMAND is one of:
> otv off-line transaction viewer, prints ZooKeeper transaction log in text format
> osv off-line snapshot viewer, prints ZooKeeper snapshot in text format
> 2) otv command will give output as:
> {noformat}
> 9/4/15 4:37:04 PM IST session 0x1004d19fe6f0002 cxid 0x00000000000c2c (epoch=0,count=3116) zxid 0x00000100000c49 (epoch=1,count=3145) create path="/4da53875-b471-4ab1-9995-03889e73c0a3/node246",data="Quick brown fox jumps over the lazy dog ",acl{e1{perms="cdrwa",id{scheme="world",id="anyone"}}},ephemeral="true",parentCVersion="8"
> {noformat}
> It is mostly same as {{org.apache.zookeeper.server.LogFormatter}} with some differences.
> * epoch and count are separated from zxid.
> * operations type will be written instead of code like createSession instead -10.
> * showing data.
> * permissions are written in letters perms="cdrwa" instead of perms="31" same as {{org.apache.zookeeper.cli.GetAclCommand}}.
> * ephemeral="true" instead of ephemeral="1"
> * etc.
> 3) osv command will give output as:
> {code}
