+Log Rotation
+============
+
+All outputs in the :ref:`outputs <suricata_yaml_outputs>` section of
+the configuration file can be subject to log rotation.
+
+For most outputs an external tool like *logrotate* is required to
+rotate the log files in combination with sending a SIGHUP to Suricata
+to notify it that the log files have been rotated.
+
+On receipt of a SIGHUP, Suricata simply closes all open log files and
+then re-opens them in append mode. If the external tool has renamed
+any of the log files, new files will be created, otherwise the files
+will be re-opened and new data will be appended to them with no
+noticeable affect.
+
+The following is an example *logrotate* configuration file that will
+rotate Suricata log files then send Suricata a SIGHUP triggering
+Suricata to open new files:
+
+::
+
+  /var/log/suricata/*.log /var/log/suricata/*.json
+  {
+      rotate 3
+      missingok
+      nocompress
+      create
+      sharedscripts
+      postrotate
+              /bin/kill -HUP `cat /var/run/suricata.pid 2>/dev/null` 2>/dev/null || true
+      endscript
+  }
+
+.. note:: The above *logrotate* configuration file depends on the
+          existence of a Suricata PID file. If running in daemon mode
+          a PID file will be created by default, otherwise the
+          :option:`--pidfile` option should be used to create a PID file.
+
+In addition to the SIGHUP style rotation discussed above, some outputs
+support their own time and date based rotation, however removal of old
+log files is still the responsibility of external tools. These outputs
+include:
+
+- :ref:`Eve <output_eve_rotate>`
+- :ref:`PCAP log <suricata_yaml_pcap_log>`
