A feature I miss and prevents us from migrating some stuff over from alertra.com is the ability to deploy a custom (bash/python/perl) script to the monitoring probes of Site24x7.

This would allow us to monitor seldom services like EPP or to implement more complex transactions to get an exhaustive  monitoring of a REST-service, node.js-Thingie etc.

I don't want to use a LinuxAgent, since this would require me to deploy my own probes in the cloud to get an outside view on things.
