Administering with Domino Administrator
This documentation provides information about the administration tools for managing and monitoring servers and databases.
Monitoring servers
This section describes how to use the tools and features that help you monitor a Domino® system.
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 from the server console.

Administering
This documentation provides information about the administration tools for HCL Domino.
- Administering with AdminCentral
  The AdminCentral application (admincentral.nsf) is automatically created by adminP on the Domino administration server. You can open AdminCentral directly from your Notes Standard or Nomad web client, without the need to start Domino Administrator. This application provides a simplified and easy-to-use way of managing fully functional Notes users and groups in a Domino deployment.
- Administering with Domino Administrator
  This documentation provides information about the administration tools for managing and monitoring servers and databases.
  - Administration tools
    Topics in this section describe the tools you can use to administer a Domino® server.
  - Managing users
    The Administration Process helps you manage users by automating many of the associated administrative tasks. For example, if you rename a user, the Administration Process automates changing the name throughout databases in the Notes® domain by generating and carrying out a series of requests, which are posted in the Administration Requests database.
  - Monitoring servers
    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 the Domino® Administrator or the server console.
    - Entitlement tracking
      As of Domino 12.0, a new internal mechanism is provided for collecting the highest entitlement that individual users have across a Domino domain. When a user appears in the ACL of a database with Reader access or above and that person has the right to access the server, the user is said to be an entitled user.
    - 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 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 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 Support, to monitor 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 Support to troubleshoot and determine the cause or causes of the performance degradation.
    - Monitoring Smart Server Startup
      With Smart Server Startup, users are prevented from connecting to a Domino server until it is fully up and ready to accept user requests. For example, during startup of the Domino server after a crash, users can connect to the Domino server only after the server has fully recovered.
    - 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 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.

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 from the server console.

From the Domino® Administrator only

About this task

You can also see the availability of each cluster member individually by doing the following:

Procedure

In the Server pane, expand either All Servers or Clusters.
Right-click the server you want, and choose Server Properties.
In the Server Properties box, click the Cluster tab.

Results

The Cluster tab in the Server Properties box shows you the name of the cluster, the availability threshold and the availability index of the server you selected, the port that is used for cluster traffic, how frequently cluster probes are sent, how many cluster probes the Cluster Manager has sent since the last time the server was started, and the names and availability indexes of all the servers in the cluster.

From the server console

About this task

Send the following command from the server console:

show cluster

This command displays the name of the cluster, several statistics for the current server, and the names and availability indexes of all the servers in the cluster.
