Dotcom-Monitor

Verifiable

The synthetic monitoring agent of Dotcom-Monitor's web monitoring platform, which loads a customer's own sites and APIs from fixed monitoring locations to check availability and performance. Dotcom-Monitor documents a product identifier appended to the browser user agent of the engine running the check: ServerView checks send DMBrowser/2.1 (SV), BrowserView checks DMBrowser/2.1 (BV), and UserView scripted checks DMBrowser/2.1 (UV). It runs only against targets the customer configured, so it is not a crawler and Dotcom-Monitor documents no robots.txt handling for it.
