  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.
  - Administration tools
    Topics in this section describe the tools you can use to administer a Domino® server.
  - Monitoring
    This section describes how to use the tools and features that help you monitor a Domino® system.
    - Monitoring the Domino® system
      You can monitor system activity and platform use using one of three tools -- the Domino® Administrator, the Web Administrator, or the server console.
    - Server Health Monitor
      You can monitor and troubleshoot performance issues using a number of different tools.
    - Domino® domain monitoring (DDM)
      Domino® domain monitoring (DDM) provides one location in the Domino Administrator client that you can use to view the overall status of multiple servers across one or more domains, and then use the information provided by DDM to quickly resolve problems.
    - The Domino® SNMP Agent
      The Domino® SNMP Agent enhances the monitoring and control features of Domino by enabling third-party management stations, which use industry standard SNMP, to manage aspects of the Domino server.
    - Overview of server maintenance
      As a Domino® administrator, a major part of your job is maintaining each server that you administer.
    - Tools for mail monitoring
      Domino® provides three tools that you can use to monitor mail. Message tracking allows you to track specific mail messages to determine if the intended recipients received them. Mail usage reports provide the information you need to resolve mail problems and improve the efficiency of your mail network. Mail probes test and gather statistics on mail routes.
    - Monitoring directory assistance
      You can monitor directory assistance by using Show Xdir command to display information about all the directories a server uses for directory services. You can also view directory assistance statistics.
    - Monitoring databases
      You can monitor database activity, replication, and document deletions.
    - Monitoring a cluster
      Domino® provides several ways to find out what is happening in a cluster and make adjustments to keep the cluster running smoothly and efficiently, so that no server is overloaded. You can monitor failover, workload balancing, and cluster replication to see how efficiently the cluster is running.
      - Displaying a list of cluster members and their availability
        You can display a list of cluster members and their availability from either the Domino® or Web Administrator, or from the server console.
      - Enabling statistic reporting in the Monitoring Results database
        One way to monitor what is happening in a cluster is to collect statistics in the Monitoring Results database. You can then view this information from the Domino® Administrator or in the Monitoring Results database itself.
      - Viewing Cluster Manager events and statistics
        After distributing databases and mail servers to balance the workload, you should track the cluster events and statistics to be sure that the workload is acceptable and that failover occurs as expected. If the statistics show a problem, you may have to make some adjustments.
      - Viewing cluster replication events and statistics
        You can view cluster replication events and statistics from the Domino® Administrator, from the Web Administrator, or in the server log file. You can see information on cluster replication activity, workload, and status, and use statistics to find replication backlogs.
      - Detecting replication delays within a cluster
        When a database on one server in a cluster is overdue to be replicated to another server, entries are created in the server log. A group of cluster currency statistics are also available to help proactively spot delays in database replication.
      - Using Tell commands to display cluster replication information
        You can use Tell server commands to display additional information about cluster replication. This information helps you determine whether to make any changes to the way you configured cluster replication or to the way you balanced the workload in the cluster. The information is displayed on the server console.
      - Monitoring all the servers in a cluster at the same time
        You can use the Domino® server monitor to monitor all the servers in a cluster at once. You can decide what information you want to monitor and how to display that information. You can monitor the cluster while you monitor other Domino servers. To tell Domino which servers to monitor and what information to monitor on each server, you create or customize a monitoring profile.
    - Monitoring slow or unresponsive servers with the Domino® Diagnostic Probe
      Use the Domino® Diagnostic Probe (DDP), a Java™ utility provided by IBM® Support, to monitor Domino 8.x and later servers that have been intermittently slow or unresponsive. The probe is a Java process (dbopen.jar) that runs in the background. The utility probes a specific Domino server over time by invoking database open transactions. If the probe detects a slow response, it will invoke Notes® System Diagnostic (NSD) to gather diagnostic data. This data is used by IBM Support to troubleshoot and determine the cause or causes of the performance degradation.
    - Monitoring quality of service
      Quality of Service, or QoS, is designed to react to the general operation of a Domino® server in order to keep that server functioning reliably and always available. If QoS detects that a server is not responding or hung, QoS probing can be configured to email an administrator about the problem and/or automatically terminate the server and restart it. QoS log information can also be useful for analysis by IBM® Support.
    - Understanding Quality of Service (QoS) behavior and logging
      This topic covers details of QoS including server and server controller behavior during kill events, failover trigger, and log file content.
  - Managing servers
    Manage Domino® servers by performing any of these tasks.
  - Managing databases
    Topics in this section describe how to set up and manage Domino® 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.
- Troubleshooting
  This section describes how to find and solve problems with IBM® Domino® server and Administrator client.

Monitoring a cluster

Domino® provides several ways to find out what is happening in a cluster and make adjustments to keep the cluster running smoothly and efficiently, so that no server is overloaded. You can monitor failover, workload balancing, and cluster replication to see how efficiently the cluster is running.

When running as part of a cluster, a Domino® server constantly monitors its workload, the workload of the other servers in the cluster, and the availability of databases throughout the cluster. In addition, Domino® monitors statistics and events that are relevant to a cluster.

There are many ways to view this information. For example, you can view it from the server console or in the log file or in the Statistics pane in the Domino® Administrator. In addition, you can collect statistic reports in the Monitoring Results database and then use the Domino® Administrator to look at the statistic reports.
