Hello
I have the problem with use fetch funcion in my script.
I use construction :local fullMessage ([/tool fetch url="$apiUrl/export.php?export" output=user as-value]->"data");

And in log I have many lines:
12:35:47 info fetch: file "export.php?export" downloaded
12:35:48 info fetch: file "export.php?export" downloaded
12:35:49 info fetch: file "export.php?export" downloaded
12:35:50 info fetch: file "export.php?export" downloaded
12:35:51 info fetch: file "export.php?export" downloaded

Is there any possibility that this information will not be in the log ?

Try onder System-Logging to add under Rules - Topic info Prefix line !fetch
