Retrieval of clusters

You use the GET operation on the api/sam/clusters element to request information about clusters that group your host computer systems. This information represents the current state of your environment and does not include any historical data.

After you retrieve the IDs of your clusters, compare them with the cluster_id column retrieved by API for computer systems to recognize which of these systems belong to which clusters. This information can also be viewed on the Hardware Inventory report in the user interface.

To retrieve information about clusters, use the following URL:
  • To use this API, you must be assigned to the All Computers group and have the View Hardware Inventory permission.
  • Each API request must be authenticated with the token parameter. You can retrieve it by using REST API for retrieving authentication token. You can also log in to BigFix InventoryLicense Metric Tool, hover over the User icon User icon, and click Profile. Then, click Show token.
  • By default, the retrieved data is sorted by id.

Query parameters

You can use query parameters to narrow down the results of your search. The following table presents query parameters that you can use for the api/sam/clusters element.
Table 2. Query parameters for retrieving clusters

The table consists of four columns and nine rows.

Parameter Description Required Value
columns[] Specify which columns to retrieve. If you do not specify this parameter, a set of default columns is retrieved. For available columns, see Response body. Example:
Retrieve the name and id columns:
No String
order Specify how to sort the returned data. The default direction for sorting columns is ascending. If you want to specify a descending sort, append desc to the column name. Example:
Order by type descending:
URL?order[]=type desc
No String
limit Specify the number of rows to retrieve. If you omit this parameter, all rows are retrieved. No Numeric
offset Specify the number of rows to skip for retrieving results. You can use it together with the limit parameter to paginate results. Example:
Retrieve 50 records starting after record 150:
No Numeric
token A unique user authentication identifier. You can view your token in the Profile preferences of BigFix InventoryLicense Metric Tool. Yes Alphanumeric

Example HTTP conversation

GET api/sam/clusters
Host: localhost:9081 
Accept: application/json 
Accept-Language: en-US
Response header
HTTP/1.1 200 OK
Content-Type: application/json
Content-Language: en-US
The above response header may be followed by different entries, depending on the current status of the data import which is represented by Import-Mode. To understand the returned values, see the following definitions:
  • none - a data import has never been initiated
  • idle - no data imports are currently running
  • running - a data import is in progress
  • pending - an action performed in the user interface requires a data import to be started for the change to take effect
If a data import has never been initiated:
Import-Mode: none
If a data import is in progress:
Import-Mode: running
Import-Progress: 41
If a data import is not running:
Import-Mode: idle/pending
Import-Last-Status: successful
Import-Last-Success-Time: Mon, 23 Jun 2014 12:18:29 GMT
