# Logging and Log Rotation
|
|
|
|
Each Planetmint node runs:
|
|
|
|
- MongoDB
|
|
- Planetmint Server
|
|
- Tendermint
|
|
|
|
When running a Planetmint node for long periods
|
|
of time, we need to consider doing log rotation, i.e. we do not want the logs taking
|
|
up large amounts of storage and making the node unresponsive or getting it into a bad state.
|
|
|
|
## MongoDB Logging and Log Rotation
|
|
|
|
See the MongoDB docs about
|
|
[logging](https://docs.mongodb.com/v3.6/administration/monitoring/#monitoring-standard-loggging)
|
|
and [log rotation](https://docs.mongodb.com/v3.6/tutorial/rotate-log-files/).
|
|
|
|
## Planetmint Server Logging and Log Rotation
|
|
|
|
Planetmint Server writes its logs to two files: normal logs and error logs. The names of those files, and their locations, are set as part of the Planetmint configuration settings. The default names and locations are:
|
|
|
|
- `~/planetmint.log`
|
|
- `~/planetmint-errors.log`
|
|
|
|
Log rotation is baked into Planetmint Server using Python's `logging` module. The logs for Planetmint Server are rotated when any of the above mentioned files exceeds 209715200 bytes (i.e. approximately 209 MB).
|
|
|
|
For more information, see the docs about [the Planetmint Server configuration settings related to logging](../node-setup/configuration#log).
|
|
|
|
## Tendermint Logging and Log Rotation
|
|
|
|
Tendermint writes its logs to the files:
|
|
|
|
- `tendermint.out.log`
|
|
- `tendermint.err.log`
|
|
|
|
If you started Planetmint Server and Tendermint using Monit, as suggested by our guide on
|
|
[How to Set Up a Planetmint Network](../network-setup/network-setup),
|
|
then the logs will be written to `$HOME/.planetmint-monit/logs/`.
|
|
|
|
Moreover, if you started Planetmint Server and Tendermint using Monit,
|
|
then Monit monitors the Tendermint log files.
|
|
Tendermint logs are rotated if any of the above mentioned log files exceeds 200 MB.
