• Various computer performance counter based metrics, namely CPU, Memory and Disk Usage
• Session Count

It is designed to indicate how suitable a XenApp Worker is to receive a new user session. It is the Delivery Controller's responsibility to calculate the load index based on the aggregate of the normalized load rule indexes generated by the various load rules. As only the Delivery Controller can determine the session load, a server's overall load index is calculated on the Delivery Controller and not the Virtual Delivery Agent.

By comparing the value of this measure across server OS machines, you can figure out whether or not load is uniformly balanced across all servers in the site.
