Previous posts referring to V 4.1.1 say that the settings are in /config/umbracosettings.config, however this key does not exist in that file in V7.

The only reference I can find is in /bin/businesslogic.xml, where the value is read in  line 1653:

      <member name="P:umbraco.UmbracoSettings.AutoCleanLogs">

            <summary>

            Gets a value indicating whether the logs will be auto cleaned

            </summary>

            <value><c>true</c> if logs are to be automatically cleaned; otherwise, <c>false</c></value>

        </member>

OK, getting somewhere:

From http://our.umbraco.org/documentation/using-umbraco/config-files/umbracoSettings/

NOTE: in v7+ many of these settings are not explicitly contained in the configuration file that is shipped with Umbraco and most of these settings have default values assigned. These default values will be expressed below and you can insert these configuration items in the file to override the defaults.

You can add a logging key to the /config/umbracosettings.config file. However the documentations does not mention the AutoCleanLogs setting, will report back as to whenther this has worked for others reference.

OK, that did not work, the Log Scrubbed entries are still being made :-(

I'm seeing this too - v7.2.1 installed via nuget.I'm writing custom log entries in a grid plugin in the Razor are you using    LogHelper.Info(...)  at all?

No? Please tell me more?

S'ok was trying to see if it was something I was doing too to zero in on the issue (to raise a bug). Do you just have a fairly standard Umbraco then? Nothing other than templates, razor etc?

The sites are running 7.2.0 as an upgrade from 7.1.6, they have a number of packages added:

Contour
ezSearch
Analytics
Config Tree
301 URL tracker...

Perhaps try a clean install with no packages and see if it  shows the same behaviour?

OK, I have done a clean install of 7.1.8 via webmatrix, and manually updated to 7.2.1, immediately the log entries started:

2014-12-18 12:44:23,177 [13] INFO  umbraco.BusinessLogic.Log - [Thread 24] Log scrubbed.  Removed all items older than 2014-10-19 12:44:23

So, it looks like a core isssue.

I have a totally clean install, no upgrades. It does look like a config setting is missing!?

I have reported this as a bug, hopeful the core team will be able to provide an answer!

There's really nothing to worry about people, it's just cleaning the umbracoLog table, which we don't actually use any more so there's hardly anything in there (maybe some packages still write to it, but it's unlikely).

So.. relax and enjoy the clean log table. :)

Won't somebody please think of the CPU cycles?!

Seroiously though - thanks Seb, nice to know it can be ignored!  

Perhaps it could be scheduled for once a day, rather than once every minute?

Any movement on this core team? I raised this issue months ago, and it persists through several releases. It is not a show stopper, but it would be nice to not have the logs fill up with this stuff, and it has to have an impact on performance!

I agree. Having the log scrubbed message pop up all the time makes it annoying to search for actual log messages.

I think adding this to your umbracoSettings.config fixes it so it only runs once a day?

<logging>
    <cleaningMiliseconds>86400000</cleaningMiliseconds>
  </logging>

Thanks Matt

a useful lead, but it would be nice if the core team could address the issue!

I will try that on  a couple of sites and see if it cures the problem.

is working on a reply...
