13.2. Simple Inventory Count: inventoryCount.js

Searches are performed using *Criteria classes; for resources, this is ResourceCriteria. A search can be very specific, passing criteria so that it returns only one resource or a small subset of resource. It is also possible to return everything in inventory.

This script runs a search with no specific criteria (ResourceCriteria()), so that every resource matches the search. It then takes the size of the results to produce a simple inventory count.

// inventory.js
rhq.login('rhqadmin', 'rhqadmin');
var resources = ResourceManager.findResourcesByCriteria(ResourceCriteria());
println('There are ' + resources.size() + ' resources in inventory');

// end script
