* Log rotation for tendermint and BigchainDB using Monit * Change file size from 100KB used for testing to 200 MB for test envs * Add docs for log rotation * remove --consensus.create_empty_blocks from monit start Because already taken care of in the config file * do not run bigchaindb with debug flag instead use config file * Address comments I - Rephrase log rotation to imply monit is not default - Add statement to explain where bigchaindb log files are created - Fix HTML comment - Add log rotation to index * Address comments II

Log rotation for a BigchainDB node
Each BigchainDB node comprises of 3 main services:
- BigchainDB server
- Tendermint
- MongoDB
To run a BigchainDB test network/dev node, that is expected to run for relatively longer periods of time, we need to consider the log rotation of these services i.e. we do not want the logs taking up large amounts of storage and making the node unresponsive or get into bad state.
Log rotation for MongoDB
Currently, we leave the log rotation of MongoDB to the BigchainDB administrator. For more notes on MongoDB log rotation please refer to MongoDB docs.
Log rotation for BigchainDB
Log rotation is baked into BigchainDB server using the logging module. BigchainDB server logs information into the following files:
bigchaindb.logbigchaindb-errors.logbigchaindb-benchmark.log
These log files are created by default in the directory from where you run bigchaindb start, if you are using monit, from
How to Set Up a BigchainDB Network guide, the default directory is: $HOME/.bigchaindb-monit/logs
The logs for BigchainDB server are rotated when any of the above mentioned file exceeds 209715200 bytes (i.e. approximately 209 MB)..
Log rotation for Tendermint
In order to set up log rotation of Tendermint, you will need to use the Monit scripts provided by us. Covered in the How to Set Up a BigchainDB Network guide.
$ monit -d 1
Monit monitors both Tendermint and BigchainDB processes as well as the Tendermint log files, tendermint.out.log and tendermint.err.log. Default location for these log files is:
$HOME/.bigchaindb-monit/logs.
Tendermint logs are rotated if any of the above mentioned log files exceeds 200 MB in size.
