When the CCS Manager acts as a load balancer, the CCS Manager routes data collection jobs from the Application Server to a CCS Manager Collector. In addition, a load balancer routes the evaluation jobs to the CCS Manager Evaluator and the reporting jobs to the CCS Manager Reporter. If your deployment includes multiple load balancers, the Application Server automatically uses each in turn. If a load balancer fails, the Application Server automatically skips the failed load balancer and uses another load balancer. This round robin assignment gives limited fault tolerance.
The CCS Manager Collector retrieves the data from the network. Potentially, your installation of CCS can have a large number of CCS Manager Collectors and the associated data collectors. The load balancer assigns jobs to eligible collectors sequentially. The load balancer does not base job assignments on the current load of the collector. If a query requires input from several CCS Manager Collectors, the load balancer distributes the query appropriately. When the CCS Manager Collectors complete the query, the load balancer combines the results and returns the results to the Application Server for storage.
An eligible CCS Manager Collector is any collector that has the ability to complete the data collection job. The collector site assignment and the installed RMS snap-in modules determine the collector eligibility.
The CCS Manager Evaluator compares collected data to the standards that you specify and saves the results for later use. Potentially, your installation of CCS can have multiple CCS Manager Evaluators. The load balancer assigns jobs to evaluators sequentially. The load balancer does not base job assignments on the current load of the evaluator.
The first CCS Manager when you deploy CCS should be assigned to the Load Balancer role.
