  - 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.
        Selecting server components to include in health reports
        Each server you monitor has a Health Monitoring Configuration document in the Health Monitoring database (DOMMON.NSF). This document specifies the server components you want to include in health reports.
        Setting up statistic alarms for the Server Health Monitor
        Just as you create an event generator for a Domino® system statistic, you create an event generator for a health statistic. Then when the statistic does not meet the defined threshold, an event is generated.
        Modifying threshold values for the Server Health Monitor
        The Index Thresholds view in the Health Monitoring database (DOMMON.NSF) displays the threshold values for each platform. To modify the sensitivity to a particular component, change the threshold value. For example, if you want to run your networks with higher utilization for servers running on a specific platform, increase the threshold for the Network Utilization component for the platform.
      - 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.
    - 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 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.
- Tuning
  Use this information to improve IBM® 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.

Modifying threshold values for the Server Health Monitor

The Index Thresholds view in the Health Monitoring database (DOMMON.NSF) displays the threshold values for each platform. To modify the sensitivity to a particular component, change the threshold value. For example, if you want to run your networks with higher utilization for servers running on a specific platform, increase the threshold for the Network Utilization component for the platform.

About this task

Keep these considerations in mind if you decide to modify threshold values. First, have a strategy in mind before you change the them. Your strategy should address your system performance needs and reflect your philosophy toward managing servers. Second, if you change threshold values remember that you have done so. Changing any system configuration parameters or adjusting user workload behavior might also have a future impact on these settings. And finally, remember that changing threshold values inappropriately may result in health values that do not accurately reflect server capacity and availability. If you get results that seem inaccurate, restore the default threshold values.

Procedure

From the Domino® Administrator, click the Server > Monitoring tab.
From the menu, choose Monitoring > Switch to Health Reports.
In theConfiguration folder, click Index Thresholds.
Click the name of the operating system and component for which you want to set the threshold, and then click Edit Threshold Document.
Specify values for the Warning Threshold and Critical Threshold.
Click OK.

What to do next

If you later decide to restore the default threshold values for a component, open the Threshold Document as described in the preceding steps and then click Restore Defaults.
