Argument Reference

The following arguments are supported:

  • name - (Required) the name of your monitor. Note: All of your monitors must have a unique name.
  • notifications - (Required) where/how you wish to be contacted when a monitor's alerting is triggered. The following key/value pairs are all options, at least one of which must not be empty. Note: When extending notification template(s), passing an empty array will overload the templated notification settings for that key.
    • templates (Optional) - ordered list of templates (by key) to extend from. Merged from left-to-right, and then with any monitor-specific template settings defined here.
    • emails (Optional) - list of emails to send alerts to
    • slack (Array) - list of slack webhook URLs (found on account settings page)
    • pagerduty (Optional) - list of pagerduty keys (found on account settings page)
    • phones (Optional) - list of phone numbers to send SMS alerts to
    • webhooks (Optional) - list of URLs (prefixed with http:// or https://) to callback to
  • rule (Required) - When creating and updating a monitor you must specify the rules that will trigger alerts to be sent.
    • rule_type (Optional) - Options are:
      • not_on_schedule // default
      • run_ping_not_received
      • complete_ping_not_received
      • ran_longer_than
      • ran_less_than
      • run_ping_received
      • complete_ping_received
    • value (Optional) - For not_on_schedule rules, this should be a cron expression like */10 * * * 1-5. For run_ping_received and complete_ping_received, no value or time_unit is accepted. For all other rule types, this should be a number that is combined with with time_unit to specify a time interval.
    • time_unit (Optional) - Not required for not_on_schedule rules. Options are:
      • seconds
      • minutes
      • hours
      • days
      • weeks
    • hours_to_followup_alert (Optional) - how long to wait between sending you follow up alerts. By default Cronitor will wait 8 hours before sending a second round of alerts. The minimum value that you may set this to is 1 hour.
    • grace_seconds (Optional) - Specify a grace period for evaluation of this rule. For not_on_schedule rules, this is used when evaluating start time and total runtime duration.
  • tags (Optional) - A list of tags. Each tag must be a string <= 50 chars.
  • note (Optional) - a note that you would like to have included in alerts. It's useful if you need to include context/tips for anyone receiving these alerts. Note that due to the size limits on SMS messages it will not be included in those alerts.
  • timezone (Optional) - Override the provider's default timezone


Monitor can be imported using the code, e.g.
