/*

 * The VMware data (zbx_vmware_service_t structure) are stored in shared memory.

 * This data can be accessed with zbx_vmware_get_service() function and is regularly

 * updated by VMware collector processes.

 *

 * When a new service is requested by poller the zbx_vmware_get_service() function

 * creates a new service object, marks it as new, but still returns NULL object.

 *

 * The collectors check the service object list for new services or services not updated

 * during last config_vmware_frequency seconds. If such service is found it is marked

 * as updating.

 *

 * The service object is updated by creating a new data object, initializing it

 * with the latest data from VMware vCenter (or Hypervisor), destroying the old data

 * object and replacing it with the new one.

 *

 * The collector must be locked only when accessing service object list and working with

 * a service object. It is not locked for new data object creation during service update,

 * which is the most time consuming task.

 *

 * As the data retrieved by VMware collector can be quite big (for example 1 Hypervisor

 * with 500 Virtual Machines will result in approximately 20 MB of data), VMware collector

 * updates performance data (which is only 10% of the structure data) separately

 * with config_vmware_perf_frequency period. The performance data is stored directly

 * in VMware service object entities vector - so the structure data is not affected by

 * performance data updates.
