RocksDB has an eventing system that clients can use to listen on specific events within the DB. These events are written to the log file when RocksDB runs. The name of the log file is LOG by default and is located in the database directory.

The whole log file is not in json format, so we need to grep to convert the output to json. Here is a bash one-liner that continuously tails the log file and prints out the events.

tail -f db/LOG | grep --line-buffered -oP '{.*}' | jq --unbuffered .
