Notify on inactive feeds

Here's a simple feature that sends an email whenever emoncms feeds become inactive for more than two hours, designed to stop those instances where you login to emoncms after a month and realise that something went wrong and it hasn't been updating for a while.

The notify control page can be accessed via the Extras menu. It can be disabled or enabled and an email address that is different from you main account email can be used if needed.

A cron job runs every 2 hours on the server to check if any feeds have become inactive for more than 2 hours but less than 4 hours. This ensures only one email is sent and historical inactivity is ignored.

Notify is now running on emoncms.org, you may want to check that your email address is correct before turning it on.
