Cloudmin sends email, chat and push messages or webhooks for resource use, guest problems, monitoring failures and failed jobs. Each rule sets what to watch, when to alert and where to send messages.
Notifications are included in both Cloudmin GPL and Pro. Choose thresholds, waiting periods, reminders and recovery messages for the host, all guests or selected guests. Send each alert to one or more destinations.
You need host and management access to change rules or destinations. Users assigned to a guest can read that guest’s events.
Set up your first alert
- Open All Notifications in the Cloudmin menu, then choose Destinations.
- Select Add destination, give it a name, choose its delivery method and enter the address and any required token. Save it with delivery enabled.
- Use Send test to check the destination. Check History for the delivery result.
- Open Rules and select Add rule. Choose the condition and which machines to monitor. For example, monitor host memory usage at or above 90% for five minutes.
- Choose your saved destination, set reminders and recovery messages as needed, and save the enabled rule. You can also create a destination while saving a rule.
Open History to check delivery results, or select a guest and open Notifications for its events.

Host outages
A powered-off host or stopped Webmin service cannot send alerts. Detecting either requires another monitoring system.
