This option lets cells manager to only attempt to sync instances that have been updated recently. i.e., a threshold of 3600 means to only update instances that have modified in the last hour. Possible values: * Threshold in seconds Services which consume this: * nova-cells Related options: * This value is used with the ``instance_update_num_instances`` value in a periodic task run.
* - ``manager`` = ``nova.cells.manager.CellsManager``
- (StrOpt) Manager for cells
- (StrOpt) Manager for cells The nova-cells manager class. This class defines RPC methods that the local cell may call. This class is NOT used for messages coming from other cells. That communication is driver-specific. Communication to other cells happens via the nova.cells.messaging module. The MessageRunner from that module will handle routing the message to the correct cell via the communication driver. Most methods below create 'targeted' (where we want to route a message to a specific cell) or 'broadcast' (where we want a message to go to multiple cells) messages. Scheduling requests get passed to the scheduler class.

* - ``name`` = ``nova``
- (StrOpt) Name of this cell
- (StrOpt) Name of the current cell This value must be unique for each cell. Name of a cell is used as its id, leaving this option unset or setting the same name for two or more cells may cause unexpected behaviour.

- (FloatOpt) Reserve percentage Percentage of cell capacity to hold in reserve, so the minimum amount of free resource is considered to be; min_free = total * (reserve_percent / 100.0) This option affects both memory and disk utilization. The primary purpose of this reserve is to ensure some space is available for users who want to resize their instance to be larger. Note that currently once the capacity expands into this reserve space this option is ignored. Possible values: * Float percentage value Services which consume this: * nova-cells Related options: * None
* - ``topic`` = ``cells``
- (StrOpt) The topic cells nodes listen on
- (StrOpt) Topic This is the message queue topic that cells nodes listen on. It is used when the cells service is started up to configure the queue, and whenever an RPC call to the scheduler is made.

- (StrOpt) Images and hosts can be configured so that certain images can only be scheduled to hosts in a particular aggregate. This is done with metadata values set on the host aggregate that are identified by beginning with the value of this option. If the host is part of an aggregate with such a metadata key, the image in the request spec must have the value of that metadata in its properties in order for the scheduler to consider the host as acceptable.

- (ListOpt) This option specifies the filters used for filtering baremetal hosts. The value should be a list of strings, with each string being the name of a filter class to be used. When used, they will be applied in order, so place your most restrictive filters first to make the filtering process more efficient. This option is only used by the FilterScheduler and its subclasses; if you use a different scheduler, this option has no effect. * Services that use this: ``nova-scheduler`` * Related options: If the 'scheduler_use_baremetal_filters' option is False, this option has no effect.

For AggregateCoreFilter, it will fall back to this configuration value if no per-aggregate setting found. NOTE: This can be set per-compute, or if set to 0.0, the value set on the scheduler node(s) will be used and defaulted to 16.0
* - ``disk_allocation_ratio`` = ``1.0``
- (FloatOpt) Virtual disk to physical disk allocation ratio
- (FloatOpt) This is the virtual disk to physical disk allocation ratio used by the disk_filter.py script to determine if a host has sufficient disk space to fit a requested instance. A ratio greater than 1.0 will result in over-subscription of the available physical disk, which can be useful for more efficiently packing instances created with images that do not use the entire virtual disk,such as sparse or compressed images. It can be set to a value between 0.0 and 1.0 in order to preserve a percentage of the disk for uses other than instances

* - ``io_ops_weight_multiplier`` = ``-1.0``
- (FloatOpt) Multiplier used for weighing host io ops. Negative numbers mean a preference to choose light workload compute hosts.
- (FloatOpt) This option determines how hosts with differing workloads are weighed. Negative values, such as the default, will result in the scheduler preferring hosts with lighter workloads whereas positive values will prefer hosts with heavier workloads. Another way to look at it is that positive values for this option will tend to schedule instances onto hosts that are already busy, while negative values will tend to distribute the workload across more hosts. The absolute value, whether positive or negative, controls how strong the io_ops weigher is relative to other weighers. This option is only used by the FilterScheduler and its subclasses; if you use a different scheduler, this option has no effect.

* - ``ram_weight_multiplier`` = ``1.0``
- (FloatOpt) Multiplier used for weighing ram. Negative numbers mean to stack vs spread.
- (FloatOpt) This option determines how hosts with more or less available RAM are weighed. A positive value will result in the scheduler preferring hosts with more available RAM, and a negative number will result in the scheduler preferring hosts with less available RAM. Another way to look at it is that positive values for this option will tend to spread instances across many hosts, while negative values will tend to fill up (stack) hosts as much as possible before scheduling to a less-used host. The absolute value, whether positive or negative, controls how strong the RAM weigher is relative to other weighers.

When set to True (the default), non-isolated images will not be allowed to be built on isolated hosts. When False, non-isolated images can be built on both isolated and non-isolated hosts alike. This option is only used by the FilterScheduler and its subclasses; if you use a different scheduler, this option has no effect.

- (StrOpt) Default driver to use for the scheduler
- (ListOpt) This option is the list of filter class names that will be used for filtering hosts. The use of 'default' in the name of this option implies that other filters may sometimes be used, but that is not the case. These filters will be applied in the order they are listed, so place your most restrictive filters first to make the filtering process more efficient. This option is only used by the FilterScheduler and its subclasses; if you use a different scheduler, this option has no effect. * Services that use this: ``nova-scheduler`` * Related options: All of the filters in this option *must* be present in the 'scheduler_available_filters' option, or a SchedulerHostFilterNotFound exception will be raised.
* - ``scheduler_driver`` = ``filter_scheduler``
- (StrOpt) The class of the driver used by the scheduler. This should be chosen from one of the entrypoints under the namespace 'nova.scheduler.driver' of file 'setup.cfg'. If nothing is specified in this option, the 'filter_scheduler' is used. This option also supports deprecated full Python path to the class to be used. For example, "nova.scheduler.filter_scheduler.FilterScheduler". But note: this support will be dropped in the N Release. Other options are: * 'caching_scheduler' which aggressively caches the system state for better individual scheduler performance at the risk of more retries when running multiple schedulers. * 'chance_scheduler' which simply picks a host at random. * 'fake_scheduler' which is used for testing. * Services that use this: ``nova-scheduler`` * Related options: None
* - ``scheduler_driver_task_period`` = ``60``
- (IntOpt) How often (in seconds) to run periodic tasks in the scheduler driver of your choice. Please note this is likely to interact with the value of service_down_time, but exactly how they interact will depend on your choice of scheduler driver.
* - ``scheduler_host_manager`` = ``nova.scheduler.host_manager.HostManager``
- (StrOpt) The scheduler host manager class to use
- (IntOpt) This value controls how often (in seconds) to run periodic tasks in the scheduler. The specific tasks that are run for each period are determined by the particular scheduler being used. If this is larger than the nova-service 'service_down_time' setting, Nova may report the scheduler service as down. This is because the scheduler driver is responsible for sending a heartbeat and it will only do that as often as this option allows. As each scheduler can work a little differently than the others, be sure to test this with your selected scheduler. * Services that use this: ``nova-scheduler`` * Related options: ``nova-service service_down_time``
* - ``scheduler_host_manager`` = ``host_manager``
- (StrOpt) The scheduler host manager to use, which manages the in-memory picture of the hosts that the scheduler uses. The option value should be chosen from one of the entrypoints under the namespace 'nova.scheduler.host_manager' of file 'setup.cfg'. For example, 'host_manager' is the default setting. Aside from the default, the only other option as of the Mitaka release is 'ironic_host_manager', which should be used if you're using Ironic to provision bare-metal instances. This option also supports a full class path style, for example "nova.scheduler.host_manager.HostManager", but note this support is deprecated and will be dropped in the N release. * Services that use this: ``nova-scheduler`` * Related options: None
* - ``scheduler_host_subset_size`` = ``1``
- (IntOpt) New instances will be scheduled on a host chosen randomly from a subset of the N best hosts. This property defines the subset size that a host is chosen from. A value of 1 chooses the first host returned by the weighing functions. This value must be at least 1. Any value less than 1 will be ignored, and 1 will be used instead
- (IntOpt) New instances will be scheduled on a host chosen randomly from a subset of the N best hosts, where N is the value set by this option. Valid values are 1 or greater. Any value less than one will be treated as 1. Setting this to a value greater than 1 will reduce the chance that multiple scheduler processes handling similar requests will select the same host, creating a potential race condition. By selecting a host randomly from the N hosts that best fit the request, the chance of a conflict is reduced. However, the higher you set this value, the less optimal the chosen host may be for a given request. This option is only used by the FilterScheduler and its subclasses; if you use a different scheduler, this option has no effect. * Services that use this: ``nova-scheduler`` * Related options: None
* - ``scheduler_instance_sync_interval`` = ``120``
- (IntOpt) Waiting time interval (seconds) between sending the scheduler a list of current instance UUIDs to verify that its view of instances is in sync with nova. If the CONF option `scheduler_tracks_instance_changes` is False, changing this option will have no effect.
* - ``scheduler_json_config_location`` =
- (StrOpt) Absolute path to scheduler configuration JSON file.
- (StrOpt) The absolute path to the scheduler configuration JSON file, if any. This file location is monitored by the scheduler for changes and reloads it if needed. It is converted from JSON to a Python data structure, and passed into the filtering and weighing functions of the scheduler, which can use it for dynamic configuration. * Services that use this: ``nova-scheduler`` * Related options: None
* - ``scheduler_manager`` = ``nova.scheduler.manager.SchedulerManager``
- (StrOpt) Full class name for the Manager for scheduler
* - ``scheduler_max_attempts`` = ``3``
- (IntOpt) Maximum number of attempts to schedule an instance
- (IntOpt) This is the maximum number of attempts that will be made to schedule an instance before it is assumed that the failures aren't due to normal occasional race conflicts, but rather some other problem. When this is reached a MaxRetriesExceeded exception is raised, and the instance is set to an error state. Valid values are positive integers (1 or greater). * Services that use this: ``nova-scheduler`` * Related options: None
* - ``scheduler_topic`` = ``scheduler``
- (StrOpt) The topic scheduler nodes listen on
- (StrOpt) This is the message queue topic that the scheduler 'listens' on. It is used when the scheduler service is started up to configure the queue, and whenever an RPC call to the scheduler is made. There is almost never any reason to ever change this value. * Services that use this: ``nova-scheduler`` * Related options: None
* - ``scheduler_tracks_instance_changes`` = ``True``
- (BoolOpt) Determines if the Scheduler tracks changes to instances to help with its filtering decisions.
- (BoolOpt) The scheduler may need information about the instances on a host in order to evaluate its filters and weighers. The most common need for this information is for the (anti-)affinity filters, which need to choose a host based on the instances already running on a host. If the configured filters and weighers do not need this information, disabling this option will improve performance. It may also be disabled when the tracking overhead proves too heavy, although this will cause classes requiring host usage data to query the database on each request instead. This option is only used by the FilterScheduler and its subclasses; if you use a different scheduler, this option has no effect. * Services that use this: ``nova-scheduler`` * Related options: None
* - ``scheduler_use_baremetal_filters`` = ``False``
- (BoolOpt) Flag to decide whether to use baremetal_scheduler_default_filters or not.
- (BoolOpt) Set this to True to tell the nova scheduler that it should use the filters specified in the 'baremetal_scheduler_default_filters' option. If you are not scheduling baremetal nodes, leave this at the default setting of False. This option is only used by the FilterScheduler and its subclasses; if you use a different scheduler, this option has no effect. * Services that use this: ``nova-scheduler`` * Related options: If this option is set to True, then the filters specified in the 'baremetal_scheduler_default_filters' are used instead of the filters specified in 'scheduler_default_filters'.
* - ``scheduler_weight_classes`` = ``nova.scheduler.weights.all_weighers``
- (ListOpt) Which weight class names to use for weighing hosts
- (ListOpt) This is a list of weigher class names. Only hosts which pass the filters are weighed. The weight for any host starts at 0, and the weighers order these hosts by adding to or subtracting from the weight assigned by the previous weigher. Weights may become negative. An instance will be scheduled to one of the N most-weighted hosts, where N is 'scheduler_host_subset_size'. By default, this is set to all weighers that are included with Nova. If you wish to change this, replace this with a list of strings, where each element is the path to a weigher. This option is only used by the FilterScheduler and its subclasses; if you use a different scheduler, this option has no effect. * Services that use this: ``nova-scheduler`` * Related options: None
* - ``soft_affinity_weight_multiplier`` = ``1.0``
- (FloatOpt) Multiplier used for weighing hosts for group soft-affinity. Only a positive value is meaningful. Negative means that the behavior will change to the opposite, which is soft-anti-affinity.
* - ``soft_anti_affinity_weight_multiplier`` = ``1.0``
- (FloatOpt) Multiplier used for weighing hosts for group soft-anti-affinity. Only a positive value is meaningful. Negative means that the behavior will change to the opposite, which is soft-affinity.

- (ListOpt) Scheduler filter classes Filter classes the cells scheduler should use. An entry of "nova.cells.filters.all_filters" maps to all cells filters included with nova. As of the Mitaka release the following filter classes are available: Different cell filter: A scheduler hint of 'different_cell' with a value of a full cell name may be specified to route a build away from a particular cell. Image properties filter: Image metadata named 'hypervisor_version_requires' with a version specification may be specified to ensure the build goes to a cell which has hypervisors of the required version. If either the version requirement on the image or the hypervisor capability of the cell is not present, this filter returns without filtering out the cells. Target cell filter: A scheduler hint of 'target_cell' with a value of a full cell name may be specified to route a build to a particular cell. No error handling is done as there's no way to know whether the full path is a valid. As an admin user, you can also add a filter that directs builds to a particular cell. Possible values: * 'nova.cells.filters.all_filters' is the default option * Otherwise it should be the full Python path to the class to be used Services which consume this: * nova-cells Related options: * None
* - ``scheduler_retries`` = ``10``
- (IntOpt) How many retries when no cells are available.

Possible values: * Positive integer value Services which consume this: * nova-cells Related options: * This value is used with the ``scheduler_retry_delay`` value while retrying to find a suitable cell.
* - ``scheduler_retry_delay`` = ``2``
- (IntOpt) How often to retry in seconds when no cells are available.
- (IntOpt) Scheduler retry delay Specifies the delay (in seconds) between scheduling retries when no cell can be found to place the new instance on. When the instance could not be scheduled to a cell after ``scheduler_retries`` in combination with ``scheduler_retry_delay``, then the scheduling of the instance failed. Possible values: * Time in seconds. Services which consume this: * nova-cells Related options: * This value is used with the ``scheduler_retries`` value while retrying to find a suitable cell.

- (ListOpt) Scheduler weight classes Weigher classes the cells scheduler should use. An entry of "nova.cells.weights.all_weighers" maps to all cell weighers included with nova. As of the Mitaka release the following weight classes are available: mute_child: Downgrades the likelihood of child cells being chosen for scheduling requests, which haven't sent capacity or capability updates in a while. Options include mute_weight_multiplier (multiplier for mute children; value should be negative). ram_by_instance_type: Select cells with the most RAM capacity for the instance type being requested. Because higher weights win, Compute returns the number of available units for the instance type requested. The ram_weight_multiplier option defaults to 10.0 that adds to the weight by a factor of 10. Use a negative number to stack VMs on one host instead of spreading out new VMs to more hosts in the cell. weight_offset: Allows modifying the database to weight a particular cell. The highest weight will be the first cell to be scheduled for launching an instance. When the weight_offset of a cell is set to 0, it is unlikely to be picked but it could be picked if other cells have a lower weight, like if they're full. And when the weight_offset is set to a very high value (for example, '999999999999999'), it is likely to be picked if another cell do not have a higher weight. Possible values: * 'nova.cells.weights.all_weighers' is the default option * Otherwise it should be the full Python path to the class to be used Services which consume this: * nova-cells Related options: * None
* - **[metrics]**
-
* - ``required`` = ``True``
- (BoolOpt) How to treat the unavailable metrics. When a metric is NOT available for a host, if it is set to be True, it would raise an exception, so it is recommended to use the scheduler filter MetricFilter to filter out those hosts. If it is set to be False, the unavailable metric would be treated as a negative factor in weighing process, the returned value would be set by the option weight_of_unavailable.
- (BoolOpt) This setting determines how any unavailable metrics are treated. If this option is set to True, any hosts for which a metric is unavailable will raise an exception, so it is recommended to also use the MetricFilter to filter out those hosts before weighing. When this option is False, any metric being unavailable for a host will set the host weight to 'weight_of_unavailable'. This option is only used by the FilterScheduler and its subclasses; if you use a different scheduler, this option has no effect. * Services that use this: ``nova-scheduler`` * Related options: weight_of_unavailable
* - ``weight_multiplier`` = ``1.0``
- (FloatOpt) Multiplier used for weighing metrics.
- (FloatOpt) When using metrics to weight the suitability of a host, you can use this option to change how the calculated weight influences the weight assigned to a host as follows: * Greater than 1.0: increases the effect of the metric on overall weight. * Equal to 1.0: No change to the calculated weight. * Less than 1.0, greater than 0: reduces the effect of the metric on overall weight. * 0: The metric value is ignored, and the value of the 'weight_of_unavailable' option is returned instead. * Greater than -1.0, less than 0: the effect is reduced and reversed. * -1.0: the effect is reversed * Less than -1.0: the effect is increased proportionally and reversed. Valid values are numeric, either integer or float. This option is only used by the FilterScheduler and its subclasses; if you use a different scheduler, this option has no effect. * Services that use this: ``nova-scheduler`` * Related options: weight_of_unavailable
* - ``weight_of_unavailable`` = ``-10000.0``
- (FloatOpt) The final weight value to be returned if required is set to False and any one of the metrics set by weight_setting is unavailable.
- (FloatOpt) When any of the following conditions are met, this value will be used in place of any actual metric value: * One of the metrics named in 'weight_setting' is not available for a host, and the value of 'required' is False. * The ratio specified for a metric in 'weight_setting' is 0. * The 'weight_multiplier' option is set to 0. This option is only used by the FilterScheduler and its subclasses; if you use a different scheduler, this option has no effect. * Services that use this: ``nova-scheduler`` * Related options: weight_setting required weight_multiplier
* - ``weight_setting`` =
- (ListOpt) How the metrics are going to be weighed. This should be in the form of "<name1>=<ratio1>, <name2>=<ratio2>, ...", where <nameX> is one of the metrics to be weighed, and <ratioX> is the corresponding ratio. So for "name1=1.0, name2=-1.0" The final weight would be name1.value * 1.0 + name2.value * -1.0.
- (ListOpt) This setting specifies the metrics to be weighed and the relative ratios for each metric. This should be a single string value, consisting of a series of one or more 'name=ratio' pairs, separated by commas, where 'name' is the name of the metric to be weighed, and 'ratio' is the relative weight for that metric. Note that if the ratio is set to 0, the metric value is ignored, and instead the weight will be set to the value of the 'weight_of_unavailable' option. As an example, let's consider the case where this option is set to: ``name1=1.0, name2=-1.3`` The final weight will be: ``(name1.value * 1.0) + (name2.value * -1.3)`` This option is only used by the FilterScheduler and its subclasses; if you use a different scheduler, this option has no effect. * Services that use this: ``nova-scheduler`` * Related options: weight_of_unavailable
