What Jetmon does

Jetpack Monitor checks the homepage of WordPress sites whose owners turned it on, with a HEAD request every five minutes, and emails them when the site goes down. A failed check is confirmed from three locations first.

Does Jetmon follow robots.txt?

robots.txt doesn't apply: Jetmon only checks the homepage of a site whose owner turned on Jetpack's downtime monitoring.

How to stop Jetmon

Turn it off in WordPress under Jetpack, Settings, Security, Downtime monitoring.

What blocking Jetmon changes

The site owner gets false downtime alerts from Jetpack.

Where to see Jetmon visits

Most bots never appear in Google Analytics. Many don't run JavaScript, so the analytics tag never loads, and Google Analytics 4 automatically excludes traffic from known bots and spiders. Your server or CDN logs record every request with its user agent, so search them for the bot's name.

OneLence recognizes Jetmon and keeps its requests out of your visitor counts.
