OpenStack - OpenStack API Extractor Service

In TrueSight Capacity Optimization, integration with OpenStack is supported through the OpenStack API Extractor Service that brings in OpenStack entities into TrueSight Capacity Optimization. 

The OpenStack API Extractor Service supports only VMware and KVM virtualizations.

The TrueSight Capacity Optimization integration with the OpenStack API Extractor Service supports OpenStack versions Liberty, Mitaka, and Newton.

The ETL now supports data collection by using Nova APIs. To use Nova APIs, apply hotfix CHF#14 or later to TrueSight Capacity Optimization, and configure the ETL. You can download the hotfix from  this location .

For information about integrating this ETL service with TrueSight Capacity Optimization, see: 

Integration steps

To integrate TrueSight Capacity Optimization with the OpenStack - OpenStack API Extractor Service, perform the following steps:

1. Navigate to Administration > ETL & SYSTEM TASKS > ETL tasks.
2. In the ETL tasks page, under the Last run tab, click Add > Add ETL.

3. In the Add ETL page, set values for the following properties under each expandable tab.

   
   

   Note

   Basic properties are displayed by default in the Add ETL page. These are the most common properties that you can set for an ETL, and it is acceptable to leave the default selections for each as is.

   Basic properties

   Property	Description
   Run configuration
   ETL task name	By default, this field is populated based on the selected ETL module. You can specify a different name for the ETL Task. Duplicate names are allowed.
   Run configuration name	The default name is already filled out. This field is used to differentiate between various configurations you can specify for the ETL task. You can then run the ETL task based on that.
   Deploy status	You can select Production or Test to mark the ETL tasks. For example, you can start by marking the task as Test and change it to Production after you have seen that the results are as expected.
   Description	(Optional) Enter a brief description for this ETL.
   Log level	Select how much detail you want the ETL log to show. The log includes Error, Warning and Info type of log information. 1 - Light: Add bare minimum activity logs to the log file. 5 - Medium: Add medium-detailed activity logs to the log file. 10 - Verbose: Add detailed activity logs to the log file. Info, Note Log levels 5 and 10 are typically used for debugging or troubleshooting ETL issues. Using a log level of 5 is general practice, however, you may choose level 10 to get a high level of detail while troubleshooting.
   Execute in simulation mode	Select Yes if you want to to validate the connectivity between the ETL engine and the target, and to ensure that the ETL does not have any other configuration issues. When set to Yes, the ETL will not store actual data into the data warehouse. This option is useful while testing a new ETL task.
   Module selection	Ensure that the Based on datasource option is selected. Note If you select Based on Open ETL template, BMC TrueSight Capacity Optimization is integrated with a Generic extractor based on the selected Open ETL template. For more information, see  Generic ETL based on a template.
   ETL module (BMC recommends that you make this selection before the previous properties)	Select OpenStack - OpenStack API Extractor Service.
   Module description	This property is a short description of the module, with a link in the user interface that points you to the technical document for this ETL.
   Entity catalog
   Sharing status	Set the sharing status by selecting one of the following options: Shared entity catalog: Select this option if, for the same entities, data is coming from multiple sources, for example, BPA ETL. Sharing with Entity Catalog: Available when you select Shared entity catalog. Select an entity catalog from the drop-down list. Private entity catalog: Select this option if, for the same entity, data is coming from a single source.
   Object relationships
   Associate new entities to	Specify the domain where you want to add the entities created by the ETL. You can select an existing domain or create a new one. Note By default, a new domain is created for each ETL, with the same name of the extractor module. As the ETL is created, a new hierarchy rule with the same name of the ETL task is automatically created, with status "active," if you update the ETL specifying a different domain, the hierarchy rule is updated automatically. Select any one of the following options: New domain: Create a new domain. Specify the following properties: Parent: Select a parent domain for your new domain from the domain selector control. Name: Specify a name for your new domain. Existing domain: Select an existing domain. Make a selection for the following property: Domain: Select an existing domain from the domain selector control. If the selected domain is already used by other hierarchy rules, a Domain conflict option is displayed. Select one of the following options: Enrich domain tree: Create a new independent hierarchy rule to add a new set of entities, relations, or both that are not defined by other ETLs (for example this ETL is managing storage while others are managing servers). ETL Migration: This configuration is recommended if a  new ETL manages the same set of entities, relations, or both (already defined in current domain tree). A typical use case is the migration from one or more ETLs to a new ETL instance. It will stop all relations imported by ETL instances and restore only valid relations after the first run; this configuration reuses an existing hierarchy rule to correctly manage relation updates.
   OpenStack configuration
   Identity service URL	Provide the URL for the OpenStack Identity Service. The Identity Service is used to obtain tokens for accessing cloud services. The URL is available on the Keystone server in the OS_AUTH_URL variable of the stack.sh file. If the identity service has an HTTPS URL, then the ETL communicates securely over HTTPS.
   Username	Provide the user name to access the Identity Service. This authenticated user must have an admin or ro_admin (read-only admin) role assigned for the specified tenant. The specified user must have read access to all OpenStack resources and endpoints.
   Password required	Select this option if a password is required to access the service.
   Password	If a password is required to access the Identity Service, enter the password.
   Tenant name	Enter the name of the Keystone tenant. The username specified above should have an admin or ro_admin role for the specified tenant.
   Cloud name	(Optional) Type a name. If you do not enter a name, a default name is created using "Cloud_" as a prefix and the OpenStack identity endpoint (host name, IP address) as the suffix.
   Domain name	Specify a domain name to collect data for or use the default domain.
   Ceilometer data collection
   In addition to collecting data for standard metrics, you can configure data collection for Ceilometer metrics for specific platforms. To enable use of Ceilometer API to extract metrics for specific platforms, configure one of the following options:
   KVM Hypervisor	Select one of the following options to collect data from the KVM Hypervisor resources: Use Nova APIs Use Ceilometer data Use Agents installed on KVM hosts or the Gateway VIS Parser ETL If you select the Ceilometer option, see OpenStack Clouds - Support for Ceilometer for more details.
   VMware Hypervisor	Select one of the following options to collect data from the VMware Hypervisor resources: Use Nova APIs Use Ceilometer data Use Agents installed on VMware hosts or vCenter ETL If you select the Ceilometer option, see OpenStack Clouds - Support for Ceilometer for more details.
   ETL task properties
   Task group	(Optional) Select a task group by which to classify this ETL.
   Running on scheduler	Select the scheduler over which you want to run the ETL. The type of schedulers available are: Primary Scheduler: Runs on the Application Server. Generic Scheduler: Runs on a separate machine. Remote: Runs on different remote machines.
   Maximum execution time before warning	Indicate the number of hours, minutes or days for which to execute the ETL before generating warnings or alerts, if any.
   Frequency	Select the frequency for ETL execution. Available options are: Predefined: Select a Predefined frequency from Each Day, Each Week, or Each Month. Custom: Enter a Custom frequency (time interval) as the number of minutes, hours, days, or weeks to run the ETL in.
   Start timestamp: hour\minute (Applies to Predefined frequency)	Indicate the HH:MM start timestamp to add to the ETL execution running on a Predefined frequency.
   Custom start timestamp	Select a yyyy-mm-dd hh:mm timestamp to add to the ETL execution running on a Custom frequency.

Raw also: Data is stored on the database in different tables at the following time granularities: Raw (as available from the original data source), Detail (configurable, by default: 5 minutes), Hourly, Daily, Monthly. Raw only: Data is stored on the database in a table only at Raw granularity (as available from the original data source). For more information, see Accessing data using public views and Sizing and scalability considerations.
   Reduce priority	Select either Normal or High.
   Remove domain suffix from datasource name	(Only for systems) If set to True, the domain name is removed from the data source name. For example, server.domain.com will be saved as server.
   Leave domain suffix to system name	(Only for systems) If set to True, the domain name is maintained in the system name. For example: server.domain.com will be saved as such.
   Update grouping object definition	If set to True, the ETL will be allowed to update the grouping object definition for a metric loaded by an ETL.
   Skip entity creation	(Only for ETL tasks sharing lookup with other tasks) If set to True, this ETL does not create an entity, and discards data from its data source for entities not found in BMC Capacity Optimization. It uses one of the other ETLs that share lookup to create the new entity.
   Scheduling options
   Hour mask	Specify a value to execute the task only during particular hours within the day. For example, 0 – 23 or 1,3,5 – 12.
   Day of week mask	Select the days so that the task is executed only during the selected days of the week. To avoid setting this filter, do not select any option for this field.
   Day of month mask	Specify a value to execute the task only during particular days within a month. For example, 5, 9, 18, 27 – 31.
   Apply mask validation	By default this property is set to True. Set it to False if you want to disable the preceding Scheduling options that you specified. Setting it to False is useful if you want to temporarily turn off the mask validation without removing any values.
   Execute after time	Specify a value in the hours:minutes format (for example, 05:00 or 16:00) to wait before the task must be executed. This option means that after the task is scheduled, the task execution starts only after the specified time passes.
   Enqueueable	Select one of the following options: False(Default): While a particular task is already running, if the next execution command arises, it is ignored. True: While a particular task is already running, if the next execution command arises, it is placed in a queue and is executed as soon as the current execution ends.
