Hi folks, I recently opensourced some tools we've been using to pull info from the transaction log and snapshot when trying to track down bugs.
The first tool, ZkTimemachine allows you to get a dump of the zookeeper state at any point in the past (which you still have the logs for). The second, GrepOps, allows you to grep through the ops in the txn log for a particular session, path or time range, or any of the above. They can be downloaded from: https://github.com/midonet/zktimemachine Also also wrote a blog post about their origin in case anyone is interested. https://medium.com/@ivankelly/mining-zookeeper-s-transaction-log-to-track-down-bugs-63b4c653bb6 -Ivan
