We’ve had a number of requests from customers that need SMS notification capabilities in Nagios XI. SMS provides a method for sending out-of-band (OOB) notifications over the cellphone network, thereby increasing the reliability and dependability of receiving critical alerts and notifications. This can be especially helpful if you need to receive alerts from your Nagios server in your data center when your Internet connection fails.
To facilitate reliable SMS notifications, we integrated the Multi-Tech iSMS GSM modem with Nagios XI. You can find the integration documentation and component at the links below:
