There are only limited set of predefined alerts available with ambari, However if you want to have your own custom alert the ambari provides an option to the users to created their own custom ambari alerts.

One such example you can find in one of my article: https://community.hortonworks.com/articles/38149/how-to-create-and-register-custom-ambari-alerts.htm...

However you will need to write the python script/logic to get the desired data and it should return CRITICAL/WARN/OK kind of responses when invoked based on the conditions that you want to add.
