Tuning
Use this information to improve HCL Domino® server, Domino Web server, and messaging performance through the use of resource balancing and activity trends, Server.Load commands, advanced database properties, cluster statistics, and the Server Health Monitor.
Using activity trends
Domino® server resource utilization can be separated into two types, system activity and user activity. System activity, which includes the level of processor, disk, memory, and network consumption that Domino generates to keep the server running, is a fixed amount of activity, as long as systems are healthy and performing smoothly. Domino servers typically use a modest percentage of their resources to run. The remaining server capacity is used to support user activity, which varies with the usefulness of the data on the server.

- Using activity trends
  Domino® server resource utilization can be separated into two types, system activity and user activity. System activity, which includes the level of processor, disk, memory, and network consumption that Domino generates to keep the server running, is a fixed amount of activity, as long as systems are healthy and performing smoothly. Domino servers typically use a modest percentage of their resources to run. The remaining server capacity is used to support user activity, which varies with the usefulness of the data on the server.
  - Setting up Activity Trends
    Learn the basic setup for Activity Trends.
  - Understanding how Activity Trends collects data
    Activity Logging collects data from the log file (LOG.NSF) and the Catalog task and stores it in the Activity Trends database (ACTIVITY.NSF). The Activity Trends Collector task processes this data and produces the trended data that is used in charting and resource balancing.
- The Server.Load tool
  Server.Load is a capacity-planning tool that you use to run tests, also called "scripts" and "workloads," against a targeted Domino® server to measure server capacity and response metrics.
- Tuning Domain Indexer performance
  Each time the Domain Indexer task runs, it looks in the Domain Catalog for new databases that have the Include in multi database indexing property enabled. It then looks for documents and files in existing databases and file systems that are new or changed since the last time it ran, and adds them to the Domain Index.
- Improving Domino® server performance
  Read the following topics for help on improving basic Domino® server performance and capacity, as well as the performance of these features: Agent Manager, databases and the Domino directory, the directory catalog, LDAP searches, mail, Web server, and UNIX™ server.
- Improving Web server performance
  After you set up the Domino® Web server and make sure that it runs properly, check the server's performance and response time.
- Improving mail performance
  Domino® includes features that improve efficiency in specific environments, but these features may not be switched on by default.
- Setting advanced database properties
  Advanced database properties include performance optimization and compression features, as well as ways to manage usability features such as unread marks and soft deletions.
- Understanding cluster statistics
  Three categories of Domino® cluster statistics help you analyze clusters
- Improving the performance of the Server Health Monitor
  If the Domino® Administration client workstation performs at 100 percent CPU utilization for a long period of time, the Server Health Monitor discards server statistic data to keep up with the workload.

Using activity trends

Domino® server resource utilization can be separated into two types, system activity and user activity. System activity, which includes the level of processor, disk, memory, and network consumption that Domino® generates to keep the server running, is a fixed amount of activity, as long as systems are healthy and performing smoothly. Domino® servers typically use a modest percentage of their resources to run. The remaining server capacity is used to support user activity, which varies with the usefulness of the data on the server.

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.

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.

Activity Trends uses these Domino® server features:

Activity logging -- To collect information that you can use to understand server activity.
Activity Trends -- To set up times for data collection and retention.
