Processes
Many individual processes support the operation of OpenStack. Many of these processes run on the controller nodes and need to be running in order to provide API availability (the nova-api process) as well as processes that coordinate functionality to other parts of the control stack (mariaDB and RabbitMQ). These processes can be checked locally, through remote SSH agents driven by shell scripts, or through automation enabled by software such as Ansible, Chef, and Puppet. Additionally, as aforementioned, there are plugins for monitoring platforms, such as Nagios, ZenOs, and Zabbix, that also include these process checks.
