Mass Delete Debug logs in Salesforce.
Since Salesforce added limit on how much debug logs can be generated in Salesforce, we started to receive errors when you open Developer Console or while trying to add another trace flags.
Deleting page by page is time consuming and annoying. Fortunately there is an easier and faster way to do this. You can use Data Loader to export debug logs and delete them all at once.
You can query Apex Debug Log (ApexLog) object export Id. Make sure to check Show all Salesforce objects checkbox.
And then just run delete to delete all Apex Logs.
