### Deployment Considerations

This documentation is based on the assumption that the basic openstack installation is done with DevStack along with Masakari and its services enabled to proceed for Masakari-monitors installation.

Note

- OpenStack installation with DevStack services are installed using `Systemd`. The `systemctl` is a tool to control the systemd and its services. This documentation refers `systemctl` commands for dealing with service related information.

- If OpenStack installed with DevStack `stable/train` with Masakari service enabled in local configuration file, then it also installs Masakari-monitors along with it.
