Audit Logging CPU Impact
This topic is only applicable to on-premises installations.
Each user transaction generates multiple log items. The Audit Logging feature enables you to perform deep analysis and monitoring of activity within Archer. This feature affects the environment sizing due to increased traffic over a TCP/IP or UDP port. The final destination for this traffic is a monitoring tool.

Administrative Functions |
50-60* *Average. Creating a simple questionnaire has a log entry rate of about 500, but most administrative functions are much smaller. Since few users typically perform administrative functions, their impact is limited. |
Audit Logging can potentially generate a large amount of network traffic between the servers and the monitoring tool. Depending on retention policies, additional disk space for storing log data can be required. Consult the sizing documentation for the chosen monitoring tool to predict this storage requirement based on an analysis of expected activities.
Audit Logging has no impact on the Database Server, but increases CPU utilization on the Web and Services Servers. In a large environment with hundreds of concurrent users, CPU utilization could double. If Audit Logging is required for a deployment, factor this into the hardware design and acquire additional cores to ensure performance is acceptable. If the increased CPU usage does not cause contention (for example, when adequate cores are available), end-user page load times are not impacted.
