+This script has been replace. Please migrate to
+[Forward log messages via notification](log-forward.md).
 
-RouterOS supports sending log messages via e-mail or to a syslog server.

-yet established. For example log messages about reboot without proper
-shutdown may be missed:
-
-> router rebooted without proper shutdown, probably power outage
-
-The script collects log messages with severity `error` and sends a
-notification.
-
-Requirements and installation
------------------------------
-
-Just install this script and [global-wait](global-wait.md):
-
-    $ScriptInstallUpdate early-errors,global-wait;
-
-... and add a scheduler:
-
-    / system scheduler add name=early-erros on-event="/ system script { run global-wait; run early-errors; }" start-time=startup;
-
-Configuration
--------------

-The notifications just require notification settings for e-mail and telegram.

+Forward log messages via notification
+=====================================
+
+[◀ Go back to main README](../README.md)
+
+Description
+-----------
+
+RouterOS supports sending log messages via e-mail or to a syslog server.
+This has some limitation, however:
+
+* does not work early after boot if network connectivity is not
+  yet established
+* lots of messages generate a flood of mails
+* Telegram is not supported
+
+The script is intended to be run periodically. It collects log messages
+and forwards them via notification.
+
+Requirements and installation
+-----------------------------
+
+Just install the script:
+
+    $ScriptInstallUpdate log-forward;
+
+... and add a scheduler:
+
+    / system scheduler add interval=1m name=log-forward on-event="/ system script run log-forward;" start-time=startup;
+
+Configuration
+-------------
+
+The configuration goes to `global-config-overlay`, there is just one parameters:
+
+* `LogForwardFilter`: define topics *not* to be forwarded
+
+Also notification settings are required for e-mail and telegram.
