The HP-UX HIDS agent can be configured to measure the rate of
events generated by a system and monitored by HP-UX HIDS.
Knowing the event rate, one can refer to the HP-UX HIDS Tuning
and Sizing primer (available on http://www.docs.hp.com) to
determine the impact of HP-UX HIDS on memory and CPU
consumption. See Appendix E “The Agent Configuration File” in the
Host Intrusion Detection System Administrator’s Guide for details.
