- Overview
  Welcome to IBM® Domino® Administrator Help.
- Installing
  Use this documentation to install the IBM® Domino® server and subsequently deploy the IBM Notes® client.
- Planning
  Use this topic as an overview of planning task.
- Configuring
  Use this information to configure an IBM® Domino® network, users, servers (including Web servers), directory services, security, messaging, widgets and live text, and server clusters. Also use this information to set up IBM iNotes® on a server using Domino Off-Line Services (DOLS).
- Securing
  This section describes IBM® Domino® security features, including execution control lists, IDs, and SSL.
- Administering
  This documentation provides information about the administration tools for managing and monitoring IBM Domino® servers and databases.
- Tuning
  Use this information to improve IBM® 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.
  - Resource balancing and 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.
  - 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.

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.

About this task

If statistic data is discarded over an extended period of time, the Server Health Monitor assigns the rating Unknown to every server. When that happens, each health report includes the statement The Domino Administrator workstation CPU is constantly saturated. Too much server statistic data is being retrieved. This condition causes inaccurate server monitoring reports.

To reduce the amount of statistic data:

Increase the server polling interval in Administration Preferences.
Reduce the number of servers being actively monitored during a Domino® server monitor session. The servers for each monitoring profile you use are added to the total number of servers being monitored. To clear this list to the servers a specific profile only, stop the Domino® server monitor, and then restart it.
Dedicate one workstation to the Server Health Monitor
