Monitoring servers
This section describes how to use the tools and features that help you monitor a Domino® system.
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.
Running QoS with other configuration options
You can run QoS with several additional options to disable probing and manage timeouts.

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.
  - 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.
    - Enabling QoS when starting Domino®
      You enable QoS at a command prompt.
    - Limiting QoS restarts
      QoS provides the option to limit the QoS restart times during one interval. When the restart times reach the time limitation, the QoS service is deactivated.
    - Pausing and resuming QoS
      QoS provides a mechanism to pause or resume the QoS service at a specific time. Pausing QoS avoids allowing the server to be killed during an option that is expected to take a long time or that is critical to server operation; examples are backups or other maintenance operations. Temporarily disabling QoS allows these operations to complete without being misinterpreted by QoS as a server problem.
    - Running QoS with a no kill option
      You can run QoS with a no kill option. When QoS detects server exceptions, it sends a single email to a specified administrator with notification of the exception instead of killing and restarting the server directly. (You can also set QoS to send mail to an administrator whether or not you enable the no kill option.)
    - Running QoS with other configuration options
      You can run QoS with several additional options to disable probing and manage timeouts.
    - Verifying that QoS is running
      If you are the not the administrator who enabled QoS, you can verify the correct setup.
  - 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.

Running QoS with other configuration options

You can run QoS with several additional options to disable probing and manage timeouts.

Procedure

Set any of the following parameters in the dcontroller.ini file.

QOS_DISABLE_PROBING=1
Disable all QoS probing.
QOS_SHUTDOWN_TIMEOUT=
The length of time a shutdown is allowed to take before QoS will smart kill the server. The default is 5 minutes.
QOS_RESTART_TIMEOUT=
The length of time a server restart is allowed (including RM restart) to take before QoS will smart kill the server. This time starts after the server is completely down (clean). The default is 5 minutes.
QOS_APPS_TIMEOUT=
The length of time a long running application is allowed to continue without showing progress before QoS smart kills the server. The default is 10 minutes.
