WP Uptime Robot allows you to monitor your servers/websites uptime and downtime from the back end of WordPress in the dashboard. It uses the uptimerobot.com API so you don’t have to take up server resources to monitor the uptime/downtime. The uptime robot API key will give you up to 50 free monitors (websites) which can each be checked every 5 minutes which is plenty for most web admins. It supports HTTPS. Ping, Keyword, and Port checks.
Uptime Robot can notify you of downtime via:
- Email to SMS
- Add a widget to show logs of recent downtimes for each monitor
- Add pretty graphs of the recent response times
