One guess would be that the site with the huge log files is that way because there is a lot to log. Check the recent files and also the Admin Logs to see if something it throwing lots of errors in the background. You can open the log files with a text editor to see what is there.

You should be able to delete the log files easily, especially the older ones. The configuration of these log files is specifies in log4net.config file.
However, as those logs contain mainly errors and warnings, you should inspect, what is causing the errors - hacker attempts or misfunctions/misconfiguration of the site or a module.
Please note that the logs in Manage >Admin Logs are stored in the database. Please make sure, they don't exceed a few thousand entries, otherwise performance of your site might get affected. If necessary, you may use my script TruncateEventlog2.sql from https://github.com/dnnwerk/truncateEventlog to cleanup these log entries.

A nice tool to get rid of old DNN log entries in the database (and keep the database smaller) is Scheduled SQL Jobs for DNN/EVOQ by Iowa Computer Gurus. You can find it here to download: GitHub - IowaComputerGurus/dnn.scheduledjobs: A DNN mdoule for scheduled Job execution.

Happy DNNing!

please be aware, that you can specify the number of events being kept per event log type. I suggest adjusting it for all active types according to your needs.

Thanks for all the information and advice! Very helpful.
I am getting a number of Host Alerts, which are Page Naming Conflicts. I don't understand why these occur. It looks as though they occur when two pages/tabs have similar names. For example if one tab is named 'Primo' and the other is 'Primo-old', it seems to cause the issue. I know I could turn off logging for this issue, but is it a concern? Is it bad practice to have similar tab names



Duplicate Page Details:Page naming conflict. Url of (sccintranet/departments/county-administrative-office/primo/) resolves to two separate pages (PRIMO-old [//Departments//CountyAdministrativeOffice//PRIMO-old] [tabid = 234], PRIMO [//Departments//CountyAdministrativeOffice//PRIMO] [tabid = 423]). Only the second page will be shown for the url.

Warning Information:PLEASE NOTE : this is an information message only, this message does not affect site operations in any way.

Suggested Action:Rename one or both of the pages to ensure a unique URL

If the pages actually have different page names, the problem may be with URL. So, go to the Page Settings, Advanced, SEO for each page and check the URLs for the pages. Delete the ones that are duplicative. You'll may need to clear the cache and restart the application to make sure that everything is cleared.

Thanks Joe.

The site is running DNN 9.1.1, so I'm looking at Page Settings > Settings > SEO

There I see two tabs (URL Management and Sitemap Settings)

Under URL Management there are four tabs, but I dont actually see any page URLs there that I can delete. Am I in the right place?

Thanks again

Tom

Page Settings for each page.

Ah - OK I get it now -

Thanks a million!
