Simple Port Check


Check that a list of provided host:ports accept TCP connections.


This plugin checks a list of ports and determines if each will accept a TCP connection.

The configuration should include a list of host:ports, for example:,,localhost:25.

This plugin generates an alert when the number of ports accepting TCP connections changes. For example, if you are monitor four ports, and one goes offline, the alert email subject will read:

Port check: 3 of 4 ports open

… and when the fourth port comes back online, the alert email subject will read:

Port check: 4 of 4 ports open

In both cases, the body of the email will list the monitored ports, and indicate the status of each.
