HP Host Intrusion Detection System (HIDS) manual Appendix B Resident Memory Consumption

Appendix B – Resident Memory Consumption

The charts below show the resident memory consumption of all HIDS processes for various systems when an artificially created rate of system call audit records (events) are applied on the system and when certain HIDS templates are running. See Appendix A above for the definition of which templates constitute the “File Templates” and how to measure the event rates on your system.

Memory Consumption on PA Processors

The graphs below show that the memory consumption of HIDS processes stays within 3-4 megabytes as the event load is increased, and in some cases, the memory consumption decreases as the event load is increased.
