Track custom events

This guide will help you track custom events using the Sqreen SDK and eventually automate security scenarios. Visit the security automation section to learn more.

Events are stored locally in a queue until the next heartbeat. Every minute, events tracked are flushed to our servers. When your app exits, events are flushed.

To complete this guide, you should have installed our library in your application. Follow the installation steps described here.

You can find a Go documentation reference of the SDK at


The Go agent does not automatically detect your web framework and you have to install the middleware functions for the web framework you use to use the SDK methods described below.

Tracking events

You use the TrackEvent() SDK method to record custom events.

To record an event, first name it:

sqreen := sdk.FromContext(ctx)

The SDK supports additional optional parameters, such as properties:

props := sdk.EventPropertyMap{"key": "value"}
sqreen := sdk.FromContext(ctx)

Later, when creating automation playbooks using this event, you can use these parameters to group events and apply conditions and detections.

Default properties

Out of the box, the Sqreen library collects some properties based on the HTTP request:

  • Client IP.
  • User agent.
  • Path requested.
  • Request HTTP verb.
  • HTTP parameters.

By default all of these properties are scrubbed of sensitive data. See PII scrubbing

Method definition

The TrackEvent() method is defined as:

func (ctx *HTTPRequestRecord) TrackEvent(event string) *HTTPRequestEvent

It creates a new event, named event, whose additional options you can set using the returned value's methods, such as WithProperties() or WithTimestamp().

Event options allows you to provide additional parameters:

func (e *HTTPRequestEvent) WithProperties(p EventPropertyMap) *HTTPRequestEvent
func (e *HTTPRequestEvent) WithTimestamp(t time.Time) *HTTPRequestEvent
func (e *HTTPRequestEvent) WithUserIdentifiers(id EventUserIdentifiersMap) *HTTPRequestEvent

  • WithProperties(): pass an object with arbitrary parameters to record custom event dimensions.

  • WithUserIdentifiers(): identify the user account which performed the event. This should be the same object provided to ForUser() method when used.

  • WithTimestamp(): manually set the event’s timestamp. By default, the current server time is used.

User tracking

To associate the event tracked with a user account, you can pass it to every TrackEvent() using WithUserIdentifiers() or rely on the ForUser() method to globally set it to the following method calls.

When TrackEvent() is provided with user identifiers, the identify value is overridden for the context of this event.

uid := sdk.EventUserIdentifiersMap{"uid": "my-uid"}

Monitor events

Congratulations! You've set up the Sqreen SDK successfully and tracked your first custom events.

Now, go to your dashboard and visit the Event Explorer to validate the events are properly recorded by Sqreen.

Next, depending on your traffic and the frequency of the tracked events, you may want to wait a few hours or days to collect enough events to craft a playbook.
