Activity Logging and Activity Trends work together. They can be enabled via the Configuration Settings document / Activity Logging tab.
Explanation:
Activity Logging servers account for their time precisely, recording user activity by person, database, and access protocol. When summarized and averaged, or trended over time, activity logging of trended statistics provides a way to measure and compare workloads across servers. You can use this information to identify the most active users and databases on each server. Using the Domino Change Manager, you can automate the creation and execution of workload redistribution plans to load a new server, decommission an old one, or balance workloads across unevenly burdened servers.
Activity Trends is part of both the Domino server and the Domino Administrator. Activity Trends collects and stores activity statistics as current observations and historical trends. The activity statistics relate to the server, databases, users, and connections of users to databases. You can explore the collected data to see how database workload is distributed across servers. Using the data, Activity Trends recommends a resource-balancing plan. Then, working with the Domino Change Manager, which is a part of the Domino server, Activity Trends provides a workflow that facilitates implementing the recommended changes.
Domino uses the collected data to determine the load on the server. Then, using resource-balancing functionality, the Analyzer applies trends analysis and statistics to intelligent algorithms that can provide computer-aided load balancing on a set of servers or simplify the server decommissioning process.
The Domino Change Manager provides workflow capability that creates resource-balancing plans and implements database moves.The Domino Change Control database (DOMCHANGE.NSF) and Domino Change Manager are part of the Domino server core functionality.
Activity Logging and Trends were first made available for Domino 6.0 as a seperate product named IBM Tivoli Analyzer for Lotus Domino. These features were rolled into the core Domino product as of version 7.0. The Domino Administration help file includes extensive documentation of these features. Activity Logging is categorized under Monitoring / Managing Servers. Activity Trends is categorized under Performance.
Default:
Both Activity Logging and Activity Trends are disabled by default.
Recommendation:
Enable Activity Logging and Activity Trends in the server's configuration document. Be sure to schedule the activity trends collector to run off-peak hours
