Overview

Watchdog is an algorithmic feature for APM, Infrastructure, and Logs. It automatically detects potential issues by continuously observing trends and patterns in metrics and logs, and looking for atypical behavior.

Monitor creation

To create a Watchdog monitor in Datadog, use the main navigation: Monitors –> New Monitor –> Watchdog.

Select alert type

In this section, choose between an APM, Infrastructure, or Logs alert:

An APM alert is created when Watchdog detects anomalous behavior on your system’s services or their child resources.

Configuring a Watchdog Monitor on APM

Select sources

Select the scope to be alerted on by configuring:

1. Predefined selectors

  • The type of Watchdog anomaly: Error Rates, Latency, Hits, or any APM alert
  • The value for APM primary tags (see the Set primary tags to scope page for instructions to configure APM primary and second primary tags)
  • The APM service (choose Any services to monitor all services)
  • The APM resource of a service (choose * to monitor all resources of a service)

2. Additional filters

  • Filter on any additional tag available on the Watchdog event (like team for example)
  • Boolean and wildcards are supported
  • Dimensions available on the predefined selectors should not be used in the additional filters

3. Group By

After your selections are made, the graph at the top of the monitor creation page displays the matching Watchdog events over the selected time frame.

Configuring a Watchdog Monitor on Infrastructure

Select sources

Select the scope to be alerted on by configuring:

1. Predefined selectors

  • The Infrastructure integration to cover (select Any Infrastructure alert to cover them all). See the Watchdog overview for a full list of integrations covered by Watchdog infrastructure)
  • The Tags available for the selected integration

2. Additional filters

  • Filter on any additional tag available on the Watchdog event (like team for example)
  • Boolean and wildcards are supported
  • Dimensions available on the predefined selectors should not be used in the additional filters

3. Group By

After your selections are made, the graph at the top of the monitor creation page displays the matching Watchdog events over the selected time frame.

A logs alert indicates that either a new pattern of error logs has been detected or that there has been an increase in an existing pattern of error logs.

Select sources

Select the scope to be alerted on by configuring:

1. Predefined selectors

  • The environment (leave empty to alert on all environments). These values are derived from the env tag in your logs
  • The service (leave empty to alert on all services). These values are derived from the service reserved attribute in your logs
  • The log source (leave empty to alert on all sources). These values are derived from the source reserved attribute in your logs
  • The log status (leave empty to alert on all status). These values are derived from the status reserved attribute in your logs
  • The log anomaly type (new Error or Spike in existing logs) determines whether the anomaly describes a new pattern of error logs or an increase in an existing pattern of error logs

2. Additional filters

  • Filter on any additional tag available on the Watchdog event (like team for example)
  • Boolean and wildcards are supported
  • Dimensions available on the predefined selectors should not be used in the additional filters

3. Group By

After your selections are made, the graph at the top of the monitor creation page displays the matching Watchdog events over the selected time frame.
