Consider performance impact of each attribute group

Learn about the performance impact of each attribute group.

Table 1 lists the impact on performance (high, medium, or low) of each attribute group. The multiple-instance attributes have been classified at the lowest level. That is, the performance overhead will increase if you do not specify compare values for one or more key values.

When you want to prevent impact on performance by any of the attribute groups listed in Table 1 you must avoid referencing that attribute group, as suggested in this list:
  • Disable the attribute group.
  • Never select workspaces that reference the attribute group.
  • Disable situations that reference the attribute group by using the "Undistributed situations" option in the Situation Editor.
  • Disable historical reporting that references the attribute group.
  • Avoid using the "Auto Refresh" refresh feature in a Workspace because this option causes a refresh of data for all attribute groups.
See the IBM® Tivoli® Monitoring User's Guide for additional information on controlling attribute group usage.
