ceilometerdb-size

Ceilometer Database Size Check.

The undercloud’s ceilometer database can grow to a substantial size if metering_time_to_live and event_time_to_live is set to -1 (infinite). We check each setting and fail if -1 is set.

  • hosts: undercloud
  • groups: pre-deployment
  • metadata:
  • parameters:
    • metering_ttl_check: metering_time_to_live
    • ttl_value: -1
    • event_ttl_check: event_time_to_live

dhcp-provisioning

DHCP on the Provisioning Network.

An unexpected DHCP server on the provisioning network can cause problems with deploying the Ironic nodes. This validation checks for DHCP responses on the undercloud’s provisioning interface (eth1 by default) and fails if there are any.

undercloud-debug

Undercloud Services Debug Check.

The undercloud’s openstack services should _not_ have debug enabled. This will check if debug is enabled on undercloud services. If debug is enabled, the root filesystem can fill up quickly, and is not a good thing.

  • groups: pre-deployment
  • metadata:
  • parameters:
    • debug_check: True

undercloud-process-count

Check the number of OpenStack processes on undercloud.

The default settings for OpenStack is to run one process (heat-engine, keystone, etc.) per CPU core. On a machine with a lot of cores this is both unnecessary and can consume a significant amount of RAM, leading to crashes due to OOMKiller.

  • groups: pre-deployment
  • metadata:
  • parameters:
    • max_process_count: 8
