IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
Avoid storing short-term history data at the Tivoli Enterprise Monitoring Server, if possible
For best performance, when configuring historical data collection, store the short-term history data at the agent rather than the Tivoli Enterprise Monitoring Server when possible. Remember that for some agent types, data is required to be stored at the Tivoli Enterprise Monitoring Server.
Storing short-term history data at the agent reduces usage on the Tivoli Enterprise Monitoring Server to collect and store data for all of the connected agents. When an attribute group has short term-history stored at the Tivoli Enterprise Monitoring Server, data from all the agents is stored in a single short-term history file. When a request is made for short-term history for an agent, the Tivoli Enterprise Monitoring Server must read all of the agent data stored in the history file to satisfy the request. This process is much less efficient. Storing short-term history data at the Tivoli Enterprise Monitoring Server increases the Tivoli Enterprise Monitoring Server processing usage, and lowers the number of agents that can be supported by the Tivoli Enterprise Monitoring Server.
