OS services monitoring

OneAgent 1.239+Dynatrace 1.240+

Dynatrace provides out-of-the-box availability monitoring of OS services.

Requirements

To monitor Linux services, systemd version 230+ is required on the monitored host.

Monitor a service

To monitor an OS service:

  1. In Dynatrace, go to OS services monitoring for the level you are configuring.

    Host level
    1. In the Dynatrace menu, go to Hosts.
    2. Find your host and select it to display the host page.
    3. On the host page, select More (…) > Settings.
    4. Select the OS services monitoring tab.
    Host-group level
    1. In the Dynatrace menu, go to Deployment status.
    2. On the OneAgents tab, turn off Show only recently connected hosts.
    3. Filter the table by Host group and select the host group you want to configure.
      • Each listed host has a Host group: <group name> link, where <group name> is the name of the host group that you want to configure.
    4. Select the host group name in any row.
    5. On the host page, select More (…) > Settings.
    6. Select the OS services monitoring tab.
    Environment level

    In the Dynatrace menu, go to Settings and select Monitoring > OS services monitoring.

Add service monitoring policy

Based on the service state and the rules, the service monitoring policy defines the way Dynatrace is monitoring your service. By default, Dynatrace comes with Auto-start Windows OS Services and Auto-start Linux OS Services policies for auto-started Windows and Linux services with failed status.

Note: The order of service monitoring policies is important. Policies that are higher on the list will proceed before those on lower positions until they are fulfilled. This allows for the creation of selective alerts or monitoring with minimal policies. If you want to monitor all auto-started services and not just those created by Microsoft, you need to add a policy with disabled alerting and/or monitoring that will verify if the manufacturer is Microsoft.

  1. On OS services monitoring for the level you are configuring based on your OS, select Add policy and define the policy, which is a collection of rules.
  2. System: select your operating system.
  3. Rule name: enter the name that will be displayed in the Summary field.
  4. Monitor: indicate whether you want to monitor service availability. Note that the service availability metric consumes DDUs. See DDU consumption.
  5. Alert: indicate whether you want alerting for your policy.

  1. Service status: set the service status for which alert should be triggered. You can use logic operations to monitor the service status. For example, $eq(running) monitors the running service state.

    Available logic operations:

    • $not($eq(paused)) – Matches services that are in state different from paused.
    • $or($eq(paused),$eq(running)) – Matches services that are either in paused or running state.

    These are the service statuses you can monitor. Use one of the following values as a parameter for this condition:

    • running
    • stopped
    • start_pending
    • stop_pending
    • continue_pending
    • pause_pending
    • paused

  1. Service status: set the service status for which an alert should be triggered. You can use logic operations to monitor the service status. For example, $eq(active) monitors the active service state.

    Available logic operations:

    • $not($eq(active)) – Matches services with state different from active.
    • $or($eq(inactive),$eq(failed)) – Matches services that are either in inactive or failed state.

    These are the service statuses you can monitor. Use one of the following values as a parameter for this condition:

    • reloading
    • activating
    • deactivating
    • failed
    • inactive
    • active

Next, you need to select which services you want to monitor based on service properties.

Select services you want to monitor

  1. Select Add rule and then select the service you want to monitor:
    • Service property used for matching:
      • Display name visible for system user.
      • Path to the binary used by OS service.
      • Manufacturer from the binary file of the service.
      • Service Name
      • Startup Type

Display name, Path, Manufacturer, Service Name

With these properties, we define the services to be monitored based on:

  • display name visible to a system user,

  • path to the service binary,

  • manufacturer of the service,

  • service name representing the name or ID under which OS service is recognized.

  • Condition in which you can define a string that:

    • Starts with – use $prefix qualifier, for example $prefix(ss).
    • Ends with – use $suffix qualifier, for example $suffix(hd).
    • Equals – use $eq qualifier, for example $eq(sshd).
    • Contains - use $contains qualifier , for example $contains(ssh).

    Available logic operations:

    • $not($eq(sshd)) – Matches if the service's property value is different from sshd.
    • $and($prefix(ss),$suffix(hd)) – Matches if service's property value starts with ss and ends with hd.
    • $or($prefix(ss),$suffix(hd)) – Matches if service's property value starts with ss or ends with hd.

Startup Type

With this property we define the services to be monitored based on their startup type.

  • Condition in which you can define a string that:

    • Equals – use $eq qualifier, for example $eq(manual).

    Available logic operations:

    • $not($eq(auto)) – Matches services with startup type different from Automatic.
    • $or($eq(auto),$eq(manual)) – Matches if service's startup type is either Automatic or Manual.

    Use one of the following values as a parameter for this condition:

    • manual for Manual - the service starts only if needed or if you invoke something to start the service.
    • manual_trigger for Manual (Trigger Start) - the service starts along with the startup of another service.
    • auto for Automatic - the service starts automatically.
    • auto_delay for Automatic (Delayed Start) - the service startup is delayed until the system has finished booting.
    • auto_trigger for Automatic (Trigger Start) - the service starts automatically on startup and may be started or stopped due to certain operating system events.
    • auto_delay_trigger for Automatic (Delayed Start, Trigger Start)
    • disabled for Disabled
  1. Select Add rule and then select the service you want to monitor:
    • Service property used for matching:
      • Service Name
      • Startup Type

Service Name

With this property we define the services to be monitored based on the service name.

Condition in which you can define a string that:

  • $contains(ssh) – Matches if ssh appears anywhere in the service's property value.
  • $eq(sshd) – Matches if sshd matches the service's property value exactly.
  • $prefix(ss) – Matches if ss matches the prefix of the service's property value.
  • $suffix(hd) – Matches if hd matches the suffix of the service's property value.

Available logic operations:

  • $not($eq(sshd)) – Matches if the service's property value is different from sshd.
  • $and($prefix(ss),$suffix(hd)) – Matches if service's property value starts with ss and ends with hd.
  • $or($prefix(ss),$suffix(hd)) – Matches if service's property value starts with ss or ends with hd.

Startup Type

With this property, we define the services to be monitored based on their startup type.

Condition in which you can define a string that:

  • $eq(enabled) – Matches services with startup type equal to enabled.

Available logic operations:

  • $not($eq(enabled)) – Matches services with startup type different from enabled.
  • $or($eq(enabled),$eq(disabled)) - Matches services that are either enabled or disabled.

Use one of the following values as a parameter for this condition:

enabled, enabled-runtimeThe service is marked as ready for startup.
staticThe unit file is not enabled and has no provisions for enabling in the install unit file section. Static units are installed as dependencies and can only be masked, but are not always executed. They will be executed only if another unit depends on them or if they're manually started.
disabledThe unit file is not enabled, but it contains an install section with installation instructions.
  1. Select Save changes.

Configure at scale using Settings API

You can use the Settings API to configure your service availability monitoring at scale.

  1. To learn the schema, use GET a schema with builtin:os-services-monitoring as the schemaId.
  2. Based on the builtin:os-services-monitoring schema, create your configuration object.
  3. To create your configuration, use POST an object.
