Hi,

I am trying to monitor Keystone and receive http notification upon increase in RPS from a certain threshold. I searched different Openstack monitoring tools and finally considered Nagios and Ceilometer to give a try.

Upto my knowledge, Ceilometer is unable to monitor Rps coming to Keystone as has a well defined list of meters like identity.authentication.sucess etc.

Coming to Nagios, Though it can monitor Keystone and keep a count for Rps but sending http notification is a problem/tricky for a newbie like me.

Does anyone has a better idea of some monitoring tool which could notify me when Rps on Keystone increase from a certain threshold?? Or tell me any easily understandable approach to send http notifications in Nagios.

Thanks
