Monitors

Sumo Logic Monitors allow you to set robust and configurable alerting policies that enable you to get notified about critical changes or issues affecting your production application. Monitors track your Metrics or Logs data in real time and send notifications when noteworthy changes happen in your production applications.

Rules

  • You need the Manage or View Monitors role capability to manage or view Monitors respectively.
  • Log Monitors use the role search filter of its creator.

  2. Provide a Query. A Logs Monitor can have one query. Metrics Monitors can specify up to five queries. When providing multiple metrics queries use the letter labels to reference a query row, see joined metrics queries for details. The monitor will automatically deduce the query row to use for the trigger. 

  3. Specify the Trigger Type. A monitor can have one critical, warning, and missing data trigger condition, each with one or more notification destinations.

    Triggers have different options depending on the query and alert type. Click the Expand button next to the query type you're using for configuration details.

    Metrics Monitors have an option to send notifications either as a group or separately. Group Notifications define whether you want single notifications per time series that match the monitor query or you want group notifications where you receive a single notification for the entire monitor.
    1. The Connection Type specifies the notification channel where you want to get notified, such as an email or webhook. See Connections for details. Monitor notifications support variables to reference monitor configuration settings or your raw data. See monitor variables for a table of the available variables.

      • Email: You must provide the recipient email addresses. You can customize the email Subject and Body.

      • Webhook: By default, the webhook configuration and payload defined on the Connection is used. You can customize your payload for each notification if needed.

    2. Select the Alert and Recovery checkboxes for each trigger type based on when you want to send a notification.  You can have different Trigger Conditions send a notification to different channels. For example, you can get notified on PagerDuty for Critical Incidents and get an email or slack notification for Warning incidents. 

    3. Add Notifications to add additional notification channels as needed. You can configure different notifications for each trigger type, critical, warning, and missing data.

  2. Enter a Name for the monitor. A Description is optional.
