System Log events for rate limits

System Log event types

Web request rate limit (org level)

The following org-based System Log events record system events related to your organization to provide an audit trail that you can use to understand platform activity and to diagnose problems.

Web request rate limit (client level)

The following client-based System Log events are fired when an individual client exceeds its assigned limit for the OAuth /authorize endpoint. The event that fires depends on the client-based rate limit mode that is set:

  • system.client.rate_limit.violation
    This event is fired when the framework is in Enforce and log per client mode and a specific client, IP address, or device identifier combination exceeds the total limit of 60 requests per minute. The System Log contains information about the client ID, IP address, device identifier, and the actual user if the user already has a valid session.

  • system.client.concurrency_rate_limit.violation
    This event is fired when the framework is in Enforce and log per client mode and a specific client, IP address, or device identifier combination makes more than two concurrent requests. The System Log contains information about the client ID, IP address, device identifier, and the actual user if the user already has a valid session.

  • system.client.rate_limit.notification
    This event is fired when the framework is in Log per client mode and a specific client, IP address, or device identifier combination exceeds the total limit of 60 requests per minute. However, the end user won't see a rate limit violation. Okta fires only a notification System Log event. The System Log contains information about the client ID, IP address, device identifier, and the actual user if the user already has a valid session.

  • system.client.concurrency_rate_limit.notification
    This event is fired when the framework is turned on in Log per client mode and a specific client, IP address, Device token combination makes more than two concurrent requests. However, the end user won't see a rate limit violation. Okta fires only a notification System Log event. The System Log contains information about the client ID, IP address, Device identifier, and the actual user if the user already has a valid session.

Operation rate limits

Some rate limits are enforced on specific actions within Okta, regardless of which API is called to invoke the action. For example, though there are multiple ways to initiate an SMS to a user, there may be a limit on how many are sent out, regardless of which API requests has been made to initiate the messages. The following event types may appear in these varying cases:

  • system.operation.rate_limit.violation
    This event type is sent once per rate limit period when a request or action is rejected for exceeding a rate limit. For example, if the rate limit that was exceeded has a reset period of one minute, then one event of this type is emitted during that period for the applicable scope.

  • system.operation.rate_limit.warning
    This event type may be sent once per rate limit period as a warning that some significant portion of your rate limit has already been used within a period. For example, you might receive a warning that you have reached 60% of your rate limit for an endpoint within a rate limit period.

  • system.operation.rate_limit.notification
    This event type can provide additional information about rate limit decisions. For example, this event might indicate that a violation event would have been emitted for a specific client rather than for a broader scope if you had chosen a different configuration.

DebugContext object for operation rate limits

For some event types, the fields provided in other response objects aren't sufficient to adequately describe the operations that the event has performed. In such cases, the DebugContext object provides a way to store additional information.

DebugContext object properties for operation rate limits

The following table describes the rate limit information that is returned in the DebugContext object.

Important: The information contained in debugContext.debugData is intended to add context when troubleshooting customer platform issues. The key names and values in the following table are standard properties for rate limit events. However, other properties may be included in the DebugContext object, for example: countryCallingCode. These types of event-specific properties may change from release to release and aren't guaranteed to be stable. Therefore, they shouldn't be viewed as a data contract but as a debugging aid instead.

Identity Engine

Note: The profile_reload type is only available for Okta Identity Engine.

Property Type Description
operationRateLimitScopeType String The type of rate limit scope affected. Example scopes: org or user
operationRateLimitSecondsToReset String The number of seconds that remain until the current rate limit period ends
operationRateLimitSubtype String The Subtype of the rate limit event affected. Example Subtypes: Email, SMS, Voice call
operationRateLimitThreshold String The relevant numerical limit that this event is associated with
operationRateLimitTimeSpan String The amount of time before the rate limit resets
operationRateLimitTimeUnit String Indicates the reset interval for operationRateLmitTimeSpan in minutes or seconds
operationRateLimitType String The type of rate limit event affected. Example types: web_request, authenticator_otp_verification, sms_factor_enroll, event_hook_delivery, elastic_rate_limit_activated, phone_enrollment, profile_reload Identity Engine , and so on

Note: Additional information for some events may be included in the DebugContext object, such as for the Notification or Warning event types. For example:
For Notification event types
A preview-type event might contain a link to where you can toggle some behavior

For Warning event types
The event might include the threshold % that is being used to trigger the warning

DebugContext object examples for operation rate limits

The following is an example System Log rate limit event where too many enrollment attempts for the SMS factor were made.

Operation rate limit subtypes

The following table includes the available Subtypes for operation rate limits.

Identity Engine

Note: The AD agent and LDAP agent subtypes are only available for Okta Identity Engine.

Subtype Description
Email The user exceeded their limit for sending email messages.
SMS The user exceeded their limit for sending SMS.
Voice call The user exceeded their limit for sending voice-call messages.
AD agent Identity Engine The user exceeded their limit for profile reload through the AD agent.
LDAP agent Identity Engine The user exceeded their limit for profile reload through the LDAP agent.
