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.
Monitoring system statistics
Domino® continuously generates and updates server statistics, which you can collect and monitor in a number of ways. From the server, you can use the Show Statistic or Show Platform Statistic commands. From the Domino Administrator, you can create statistics profiles and charts.
Statistic Collector task
The Statistic Collector task, formerly known as the Collector task, gathers statistics for one or more servers in a domain and, by default, creates statistic reports in the Monitoring Results database (STATREP.NSF).

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.
    - Monitoring Configuration application (EVENTS4.NSF)
      The Monitoring Configuration application includes a configuration user interface for use with Domino® Domain Monitoring (DDM). Use this interface to set up DDM probes and a collection hierarchy of servers that collect information from other servers.
    - Monitoring server shutdown
      Domino's Shutdown Monitor task ensures that Domino® terminates when requested to do so, that is, the server does not hang while attempting to shut down.
    - Monitoring processes running in the Domino® server environment
      Domino's "Process Monitor" task applies to Domino® on Microsoft™ Windows™ platforms only. This task monitors the processes that should be running as part of the Domino server environment.
    - Monitoring events on the Domino® system
      Events signal both that the system is working smoothly, processing data, and performing tasks; or that the system is malfunctioning, perhaps by not processing data or performing required tasks.
    - Event generators
      Event generators gather information by monitoring a task or a statistic or by probing a server for access or connectivity. Each event generator has a specified threshold or condition, which, when met, causes an event to be created The event is passed to the Event Monitor task, which checks whether an associated event handler has been defined. If an event handler has not been defined, the Event Monitor task does nothing. If an event handler has been defined, the Event Monitor carries out the instructions in the event handler. The Event Monitor task, formerly know as the Event task, starts automatically when you start the server and must run on all servers that you want to monitor.
    - Monitoring iNotes® activity
      You can determine the number of active IBM® iNotes® users on a system and log iNotes request information. To monitor this activity, set up activity logging to include iNotes.
    - Event handlers
      An event handler defines the action that Domino® takes when a specific event occurs.
    - Viewing an event report
      The Monitoring Results database (STATREP.NSF) stores statistic and event information, depending on how you configured the Statistic Collector server task and event handler documents. For each event, a report records the server that originated the event; the time, severity, type and error code of the event; and a brief description of the event.
    - Viewing event messages, causes, and solutions
      Each event that occurs on the Domino® system has an associated event message that is stored in the Monitoring Configuration database (EVENTS4.NSF). The message text often provides information about possible causes and solutions.
    - Customizing the Domino® server and administrator console
      By creating a Server Console configuration document for the server you are monitoring, you can specify the text, background, and color attributes that the Domino® server console uses to display monitoring information. By default, the Domino Administrator server console uses the same attributes, but you can override the defaults and customize the appearance of the Domino Administrator server console.
    - Monitoring system statistics
      Domino® continuously generates and updates server statistics, which you can collect and monitor in a number of ways. From the server, you can use the Show Statistic or Show Platform Statistic commands. From the Domino Administrator, you can create statistics profiles and charts.
      - Statistic Collector task
        The Statistic Collector task, formerly known as the Collector task, gathers statistics for one or more servers in a domain and, by default, creates statistic reports in the Monitoring Results database (STATREP.NSF).
      - Setting preferences for monitoring and statistics
        You must set monitoring Administration Preferences to generate statistics and reports and to specify the location from which you are monitoring statistics.
      - Creating a Server Statistic Collection document
        You use a Server Statistic Collection document to designate one collector server and one or more other servers from which the collector server collects statistics. By default, the collector server reports the statistics to the local Monitoring Results database (STATREP.NSF), unless you specify a different database.
      - Server statistics and replication status
        One of many types of server statistics are the replication statistics that indicate the status of replication attempts that occur on the Domino® server.
    - Platform statistics
      In addition to tracking server statistics, Domino® tracks operating-system performance statistics. You can view these statistics from the Domino Administrator, along with your Domino statistics, which helps you with Domino server monitoring and tuning. You can include platform statistics in any statistic monitoring task you perform with the Domino statistics, including using them in monitoring and statistic profiles, and charting them.
    - Using the Domino® Administrator to monitor statistics
      Using the Domino® Administrator, you can create a statistic profile that you use to monitor the same set of statistics periodically or to compare performance on different servers.
    - Using mail-in statistics
      If you can access Notes® mail on a server, you can collect statistics from the server and mail them to yourself. Use mail-in statistics when the Domino® Administrator is not available or you do not have administrator access to a server.
    - Charting statistics
      You can graphically display the statistics generated by Domino®, by creating statistics charts. To chart sets of statistics on a regular basis, you can define statistics profiles. Using statistics charts you can track and visualize statistics in real time or historically. Real-time charts reflect the current server activity. Historical charts pull information from the local Monitoring Results database (STATREP.NSF). You can also create statistic profiles so that you can chart a specified set of statistics routinely.
  - 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 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.

Statistic Collector task

The Statistic Collector task, formerly known as the Collector task, gathers statistics for one or more servers in a domain and, by default, creates statistic reports in the Monitoring Results database (STATREP.NSF).

There are two ways to set up statistic collection. You can start the Statistic Collector task on each server, which then collects its own statistics and creates reports in the local Monitoring Results database. Or you can start the Statistic Collector on one server that you set up to collect statistics from one or more servers and create reports in a specified Monitoring Results database.

For example, if you use one designated server to collect statistics from other servers, you start the Statistic Collector task only on that server and create a Server Statistic Collection document to identify the servers from which to collect statistics. Reports are created in the Monitoring Results database (STATREP.NSF) on the designated server.

The Statistic Collector task loads automatically on a server if it is in the task line of the NOTES.INI file.

In the Domino® Administrator, the Statistic Collector starts when you start the Domino® server monitor, when you chart real-time statistics, or when you access the Server > Statistic tab. You can also set a Monitoring Administration Preference so that the Statistic Collector task starts automatically when you start the Domino® Administrator. The Statistic Collector task continually adds new servers from which it gathers statistics as you monitor or chart statistics from additional servers.

For example, in the Domino® server monitor, if you begin monitoring the servers in the Renovations1monitoring profile, the Collector task begins collecting statistics from the servers listed in the Renovations1 profile. Then if you switch to charting and chart the statistics in the RenovationsEast statistics profile, the Statistic Collector task simply adds the servers in the RenovationsEast statistics profile to the list of servers from which it is gathering statistics. It does not stop gathering statistics from the servers in the first group you monitored in the Renovations1 profile.
