Custom markers

Custom markers can be added to graphs and charts to mark important changes. They work similarly to Deploy markers, which let you know when a deployment was made. There are several ways to send custom markers, through our UI, API and public endpoint API. The Ruby gem also includes a helper class to create custom markers through our public endpoint. See the example below on how it can be used:

Appsignal::CustomMarker.report(
  # The icon shown on the timeline
  :icon => "🎉",
  # The message shown on hover
  :message => "Big event happened!",
  # Any time object or a string with a ISO8601 valid time is accepted
  :created_at => Time.now
)

You can call this helper anywhere in your application where an event occurs that needs to be tracked on the graph timeline, like Rake tasks.
