Flushing the Agent cache based on the number of data points

The /AgentSetup/prmHistCacheSize configuration variable sets the number of data points allowed in the cache, for a specific parameter, before writing the cache to the history file. For example, if you set the value of prmHistCacheSize to 10, when the agent has collected 10 data points for a parameter it writes the data to the history file.

To turn off history cache and thus turn off recording history, set this variable equal to or less than 1.
