Monitoring servers
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.
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.

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.
- 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.
  - 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.
      - Setting up the Server Health Monitor
        To create Server Health Monitor reports and historical charts, you must enable both the Server Health Monitor and statistic reporting.
      - Starting the Server Health Monitor
        To start the Server Health Monitor, you start the Domino® server monitor, which automatically monitors the most recently viewed server profile or profiles that you configured to run in the background.
    - 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.
  - 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.
  - 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.

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.

Table 1. Server ratings
Rating	Description
Never Seen	The server has never been seen running during the current server monitor session.
Healthy	The server is performing within acceptable tolerances.
Warning	One or more server components are approaching unacceptable levels of poor performance.
Critical	The server is experiencing one or more of these critical problems: One or more server components are failing to perform acceptably One or more tasks on the server have issued a fatal error One or more tasks on the server are not responding
Server Down	The server is not responding; therefore, it isn't responding to requests for statistics.

Table 2. Component ratings
Rating	Description
Healthy	The server component appears to be running correctly.
Warning	The server component is approaching unacceptable levels of poor performance.
Critical	The server component is failing to perform acceptably.
Fatal	The task related to this component has issued a fatal error.
Not Responding	The task related to this component is not responding.
