- Securing
  This section describes security features, including execution control lists, IDs, and SSL.
- 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).
      - 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 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.
- Tuning
  Use this information to improve HCL 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 HCL Domino® server and Administrator client.

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.

About this task

When a server rating is Warning or Critical, or when there is a configuration issue, check the Overall Health Report in the Health Monitoring database (DOMMON.NSF). Each server health report provides short-term and long-term recommendations for restoring the server's rating to healthy.

For example, if the Memory Utilization component receives a Warning rating, the short-term solution may be to check the server for unnecessary processes that have been loaded. The long-term recommendation may be to add memory or to check the server's page-file allocation.

Procedure

To view server health, make sure you complete these preparation tasks:
1. Enable the Server Health Monitor in Administration Preferences.
2. Start the Domino® Server Monitor.
3. Allow the monitor to run for a few minutes longer that the specified polling interval.
From the Domino® Administrator, click the Server > Monitoring tab.
In the Health column (Hea), the Server Health Monitor uses these icons to indicate the server's overall health:
- Green thermometer -- the server's overall health rating is Healthy. All server components are within the appropriate range.
- Yellow thermometer -- the server's overall health rating is Warning. One or more server components being monitored are approaching unacceptably poor levels of performance.
- Red thermometer -- the server's overall health rating is Critical. One or more server components being monitored are failing to perform within acceptable tolerance levels.
