Administering
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.
- 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.
    - Server Health Monitor statistics
      The Server Health Monitor reports a statistic for the overall server and for individual components. Each statistic corresponds to a rating.
    - Server Health Monitor ratings
      The Current® Reports view of the Health Monitoring database (DOMMON.NSF) displays the assigned rating for each enabled server and server component. When a server rating is Warning or Critical, the Overall Health Report provides recommendations for correcting the problems.
    - Using the Server Health Monitor
      Using the Server Health Monitor, you can perform various tasks to monitor the health of servers and server components.
    - Server Health reports
      Based on information gathered by the Domino® Server Monitor, the Server Health Monitor issues Health reports. Health reports are stored in the Health Monitoring database (DOMMON.NSF).
    - Working with Server Health Monitor statistics
      Health statistics are recorded in the Monitoring Results database (STATREP.NSF).
      - Monitoring server health in the Domino® server monitor
        You monitor server health in the Domino® server monitor by using monitoring profiles.
        Domino® server monitor
        The Domino® server monitor displays real-time statistics and provides a visual representation of the status of servers and server tasks. You can view all servers or a subset of servers, and you can view the status by state or by timeline.
        Viewing the Domino® server monitor
        The Domino® server monitor has two views: By Timeline and By State.
        Starting the Domino® server monitor
        The Domino® server monitor does not start by default; however, you can change the monitoring defaults in the Administration Preferences so that it does.
        Profiles and the Domino® server monitor
        To facilitate monitoring servers, tasks, and statistics, the Domino® server monitor creates a set of default profiles.
        Creating a custom profile in the Domino® server monitor
        To create a custom profile, you modify a default profile and then save it with a new name.
        Modifying a default profile in the Domino® server monitor
        You can add tasks or statistics to a default profile. If you add or remove a server from a default profile, Domino® prompts you to save the profile with another name.
        Specifying profiles to use when you start the Domino® server monitor
        By default, the profile that was being monitored when you stop the server monitor is the profile that will be monitored when you start the server monitor. To override this default behavior, you can specify which profiles to monitor when you start the Domino® server monitor.
        Setting task status indicators for the Domino® server monitor
        In the By State view, each task that you monitor has an associated status level. You determine which status levels to monitor, then each task that you monitor displays a current status indicator or task error.
        Using shortcuts in the Domino® server monitor
        The Domino® server monitor includes shortcuts that provide additional information on the server and server task status without having to move from the Server > Monitoring tab.
    - Viewing server health with the Server Health Monitor
      After the first polling interval passes, the Server Health Monitor posts a report of server health, which you can view in the Domino® server monitor for a quick visual representation of your server's health.
  - 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.
  - 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 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.

Domino® server monitor

The Domino® server monitor displays real-time statistics and provides a visual representation of the status of servers and server tasks. You can view all servers or a subset of servers, and you can view the status by state or by timeline.

The Domino® server monitor creates a set of default system profiles that include all servers, servers in each domain, servers in clusters in each domain, and servers in the Favorites bookmark file. In addition, you can create custom profiles that specify the servers, server tasks, and statistics to monitor. For example, you can create a mail-server profile and select only server tasks and statistics related to mail delivery.

You can use the server monitor to perform these tasks:

View server monitor statistics by timeline or by state
Display past error states only
Add or remove a server to monitor
Add or remove server tasks or statistics from a selected server or from all servers
Create and edit server monitor profiles
Move to the Status or Messaging tab to troubleshoot an error report
Sort statistics columns that have numerical values
Right-click a statistic to retrieve additional information about it
For numerical statistics, display the difference between the current statistic and the statistic generated one hour earlier

Note: The Domino® server monitor is not available in the Web Administrator.
