+Nimbus logs are written to stdout, and optionally to a file. Writing to a file for a long-running process may lead to difficulties when the file grows large. This is typically solved with a *log rotator*. A log rotator is responsible for switching the written-to file, as well as compressing and removing old logs.
 
-To set up file-based log rotation, an application such as [rotatelogs](https://httpd.apache.org/docs/2.4/programs/rotatelogs.html) is used - `rotatelogs` is available on most servers and can be used with `docker`, `systemd` and manual setups to write rotated logs files.
+## Using "logrotate"
 
-In particular, when using `systemd` and its accompanying `journald` log daemon, this setup avoids clogging the the system log by keeping the Nimbus logs in a separate location.
+[logrotate](https://github.com/logrotate/logrotate) provides log rotation and compression. The corresponding package will install its Cron hooks (or Systemd timer) -- all you have to do is add a configuration file for Nimbus-eth2 in "/etc/logrotate.d/nimbus-eth2":
 
-## Compression
+```text
+/var/log/nimbus-eth2/*.log {
+	compress
+	missingok
+	copytruncate
+}
+```
 
-`rotatelogs` works by reading stdin and redirecting it to a file based on a name pattern. Whenever the log is about to be rotated, the application invokes a shell script with the old and new log files. Our aim is to compress the log file to save space. [repo](https://github.com/status-im/nimbus-eth2/tree/unstable/scripts/rotatelogs-compress.sh) provides a helper script to do so:
+The above assumes you've configured Nimbus-eth2 to write its logs to "/var/log/nimbus-eth2/" (usually by redirecting stout and stderr from your init script).
+
+"copytruncate" is required because, when it comes to moving the log file, `logrotate`'s default behaviour requires application support for re-opening that log file at runtime (something which is currently lacking). So, instead of a move, we tell `logrotate` to do a copy and a truncation of the existing file. A few log lines may be lost in the process.
+
+You can control rotation frequency and the maximum number of log files kept by using the global configuration file - "/etc/logrotate.conf":
+
+```text
+# rotate daily
+daily
+# only keep logs from the last 7 days
+rotate 7
+```
+
