This documentation provides information about the administration tools for managing and monitoring IBM Domino® servers and databases.
Monitoring
This section describes how to use the tools and features that help you monitor a Domino® system.
Server Health Monitor
You can monitor and troubleshoot performance issues using a number of different tools.
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.
Charting Server Health Monitor statistics
To chart the performance of Server Health statistics, you must be actively monitoring all servers whose performance you want to chart in the Domino® server monitor. In addition, if you want to chart health statistics historically, you must enable the generation of statistic reports while monitoring or charting statistics in the statistic Administration Preferences.

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.
    - 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).
    - 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.
      - Excluding a server from the Server Health Monitor report documents
        The Server Health Monitor creates health reports for each server you are actively monitoring and stores them in the Health Monitoring database (DOMMON.NSF).
      - Charting Server Health Monitor statistics
        To chart the performance of Server Health statistics, you must be actively monitoring all servers whose performance you want to chart in the Domino® server monitor. In addition, if you want to chart health statistics historically, you must enable the generation of statistic reports while monitoring or charting statistics in the statistic Administration Preferences.
  - 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 database activity using Statlog
    Monitor database activity regularly. If database activity is high and users report performance problems, you can take a number of steps to improve performance.
  - Monitoring replication of a database
    If there are replicas of a database, you can use any of these methods to monitor replication daily.
  - 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 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.

Charting Server Health Monitor statistics

To chart the performance of Server Health statistics, you must be actively monitoring all servers whose performance you want to chart in the Domino® server monitor. In addition, if you want to chart health statistics historically, you must enable the generation of statistic reports while monitoring or charting statistics in the statistic Administration Preferences.

You can chart real-time and historical performance of Server Health statistics. Real-time health statistics are gathered by the Statistic Collector server task in the Domino® Administrator and are stored in memory, for use when charting real-time statistics. Historical health statistics are created from the historical statistics information stored in the local Monitoring Results database (STATREP.NSF).

You can also create statistic profiles to monitor groups of servers and associated statistics routinely. There is a limit of 25 statistics in each statistic profile.

You can perform the following tasks when charting server health statistics:

Create statistics profiles
Modify statistic profiles
