Hi ,

Thanks for bringing this up. 

We don't directly support monitoring of kannel/smpp. Alternatively, you can write a plugin or download the Nagio's Kannel plugin to monitor the same. 

Writing a Plugin:

Using our Custom Plugin, you can write your own plugin and monitor the Kannel/smpp locally or remotely.

You can also download the Nagios's Kannel Plugin and integrate it with our Linux agent and monitor the same.
